7 Common Tax Filing Errors and Mistakes to Avoid
The risks of making avoidable tax mistakes, especially near the tax filing deadline, are often high, some with negative consequences that can even lead to a tax audit or unnecessary delays in processing returns. Here are seven such mistakes that can be avoided by simply checking your completed returns before sending them to the IRS:
1. Incorrect Social Security numbers: Make sure all Social Security numbers, whether for yourself, children, spouse or dependents, are accurate. The IRS has rated this as the most common return mistake, so you should check it out. This must be done whether it is submitted on paper or online.
2. Name errors: Make sure you use your own name, especially if you’re married and filing separately instead of your spouse’s. Make sure the name on the statement matches the name on your Social Security card. Contact the Social Security Administration to get a new card if there is a change in name or names.
3. Incorrect/multiple filling states: You can only submit one filing status at a time. Although online tax preparation software does not support multiple selections of filing states, it is common for paper filers to check more than one state at a time. Make sure this doesn’t happen.
4. Signature of all signature areas: Your statement is only valid if it is signed by all relevant parties. If you’re filing a joint return, make sure your spouse signs as well, as failure to do so can result in delays or even rejection of the return.
5. Mathematical errors: Mathematical errors are common, especially when manually calculating the amount of tax payable. Avoid this by using only the most current version of the tax tables, check the math and make the necessary corrections.
6. Claim of credits and deductions: The rules for IRS credits and deductions are constantly changing every year, and you should check to make sure you qualify for some, such as the earned income credit, which is calculated based on gross income before to claim. The same applies to deductions, some of which are age-specific. To avoid delays in processing your return, claim credits and deductions to which you are entitled.
7. Routing and account numbers: Most taxpayers claiming refunds prefer IRS direct deposits, which are only possible if you provide accurate bank account and routing numbers. It is very easy to correct this error; just review the details before submitting.
Finally, don’t hesitate to request a tax return extension if you can’t file your return on time. This will ensure that you avoid not only common tax mistakes, but also IRS interest and penalties.

Ray Ban AAA Sunglasses Black Pattern Blue Rayban-0362,associated state dependent two point boundary value problem A
Two experiments were conducted to UK-Ray Ban Sunglasses 4216 Predator Leopard examine the relationship between individual differences in the general desire for control and the illusion of control. In Experiment 1, high desire for control college students bet significantly more than lows in a gambling game when they were playing with familiar cards, but not when playing with unfamiliar cards. In Experiment 2, high desire for control subjects demonstrated the illusion of control in a coin-toss game when they experienced success in anticipating the outcome of the coin toss at the begnning of the sequence. These subjects believed they had performed better on the task and anticipated they would do better on upcoming tasks than low desire for control subjects or subjects who experienced failure at the beginning of the sequence. In this paper, a fast numerical algorithm for nonlinear receding horizon control is proposed. The control input is updated by a differential equation to trace the solution of an associated state-dependent two-point boundary-value problem. A linear equation involved in the differential equation is solved by the generalized minimum residual method, one of the Krylov subspace methods, with Jacobians approximated by forward differences. The error in the entire algorithm Ray Ban AAA Sunglasses Black Pattern Blue Rayban-0362 is analyzed and is shown to be bounded under some conditions. The proposed algorithm is applied to a two-link arm whose dynamics is highly nonlinear. Simulation results show that the proposed algorithm is faster than the conventional algorithms.


What does it really mean when you see that a dilution is 1:64, 64:1 or so many ounces of cleaning chemical per gallon? The proper way to show a dilution is how many parts of the concentrated product (usually 1) are to be diluted to how many parts of the dilutant or extender (usually water or a solvent). As an example, 1-ounce to a gallon (128-ounces) would be 1:128, not 128:1.
To convert dilution ratios to ounces per gallon divide 128 (the number of ounces per gallon) by the dilution ratio. For example, for a dilution rate of 1:32, the ounces per gallon would be determined by the calculation: 128 ÷ 32 = 4-ounces per gallon of water.
If given the ounces per gallon, calculate the dilution rate by dividing the concentrate ounce per gallon into 128. For example, if a product dilutes at 4-ounces per gallon, the calculation would be: 128 ÷ 4 = 32, or a dilution rate of 1:32.
One of the most common errors in figuring out how much diluted product will result from a certain ratio is forgetting to add the amount of the concentrate to the total. For example, 1-ounce of a product diluted at 1:64 makes 65-ounces, not 64. This includes not only the 64-ounces of dilutant, but also the original 1-ounce of concentrate.
For metric conversion, here are some key equivalents:
Liter = 33.8-ounces, 1.057-quarts or 0.264-gallon
Gallon = 3.784-liters
Quart = 0.946-liter

Supplement of this angle is also x. ६ के हल में हम फलनों के प्राचलिक रूपों के अवकलज ज्ञात करना सीखते हैं। इन प्रश्नों में दो चर राशिओं x और y में एक तीसरी चर राशि की सहायता से संबंध बनाया जाता है। यह तीसरी राशि ही प्राचल कहलाती है। Click here to get the solutions of other exercises of , Go back to Solutions. The solutions for chapter 5 is given below exercise-wise to help students understand each concept of Elementary Shapes. Also, all the interior angles of the rectangle are of the same measure, i. Other than given exercises, you should also practice all the solved examples given in the book to clear your concepts on Understanding Elementary Shapes.
Acute angle is always lesser than 90º. The angle of measure 90° i. Therefore, this is the disadvantage in comparing line segments by mere observation. Where will the hand of a clock stop if it? Answer 90 Question 3 There are two set-squares in your box. Answer: a At 6 b At 8 c At 8 d At 2 Question 3: If you stand facing following cases, what fraction of revolution would have you been moved: a East and turn clockwise to face north? When we compare two line segments of almost same lengths, we cannot be sure about the line segment of greater length. Answer: A square is a quadrilateral.
Question 10: Indicate which pairs of angles are: i Vertically opposite angles. Remember you have to use all the available matchsticks in each case Name the type of triangle in each case. In this exercise, we have to learn about differentiation of parametric equation When two variables are expressed in the terms of third variable, the third variable is called parameter. Answer: i 90° ii 180° iii Supplementary iv Linear pair v Equal vi Obtuse angles Question 14: In the adjoining figure, name the following pairs of angles. Therefore, two obtuse angles cannot be in a supplementary angle pair.
Give rough sketch pentagons by drawing its diagonals. To keep the wire taut, let it be fixed to a stake at A. Perfect Square is a square of an integer and it is always positive. How many right angles do you make if you start facing a south and turn clockwise to west? Can you make a triangle with: a 3 matchsticks? Question 7: Can two angles be supplementary if both of them are: i Acute? Answer a Perpendicular b Not perpendicular c Perpendicular d Not perpendicular Question 2. So, v , vii and viii are not perfect squares.
Question 5: Measures the largest angle and find their angles. To prove : i ii iii Proof : i Since Therefore and each triangle is similar to Because Therefore ii Since, Therefore iii Since, Q. Therefore, a rectangle can be thought of as a special parallelogram. Therefore, it is better to use divider rule than a ruler, while measuring the length of a line segment. Product we get when a number is multiplied with itself is called a Square Number. Does the angle become larger? Two more examples are d The given figure is an octagon as this closed figure is made of 8 line segments.

Question 5: The line segment from the diagonal joins the any of two vertices in the polygon and is not in the side of the given polygon. . It can be observed that two angles, even of 89º, cannot add up to 180º.
The chapter summary and group activities help to develop a grip on the topic that also strengthens the foundation of the students on Elementary Shapes to deal with further complex topics meritoriously. Because Hence, the stake may be placed at distance of m from the base of the pole. Question 8 Find the measure of the angle shown in each figure. Students can use these methods to solve problems on textbooks, sample papers and previous year question papers. Looking through a magnifying glass, does the angle becomes larger? The sum of the measures of a supplementary angle pair is 180º. Answer: i For 3 matchsticks An acute angle triangle is formed with 3 matchsticks because the sum of the two sides is greater than the third side.
How far apart will be the two planes after 1½ hours? Here, their measures are 57º and 57º respectively. However, here their measures are 72º and 82º respectively. First estimate and then measure. Question 4: Analyze the diagram. Question 4: Draw a rough sketch of a regular hexagon. .
In the , we studied some basic shapes like line, line segment, angle, triangle, quadrilateral, polygon. Say True or False : a Each angle of a rectangle is a right angle. Please write in the comment section for any error or any solution related queries from the exercise. Therefore, it is not an appropriate method to compare line segments having a slight difference between their lengths. Answer a At 6 b At 8 c At 8 d At 2 Question 3 Which direction will you face if you start facing a east and make ½ of a revolution clockwise? Answer a ¾ b ¾ c ½ Question 5. This is because the sum of the lengths of any two sides of a triangle is always greater than the length of the remaining side of the triangle. Take any point C lying in between A and B.


$300 for the 15 hour Basic seminar
$575 for the 30 hour Premier seminar (usually offered in the summer/fall)
This includes: Instruction and textbook
$50 per hour for you alone
$40 per hour for you and a friend
$35 per hour for you and 2 friends
Attendance at all sessions of the seminar is highly encouraged. Students may be stronger in some areas than others and only desire instruction in their weaker areas. We encourage students to work on improving all areas of their test score because improving their strong areas will have an impact on the overall score as well.
For example, if Joe scores 25 on Math and 17 on English, he may feel that he only needs to improve the English score. However, if he works on both subjects and his math improves to 29 and English improves to 21, his cumulative score will increase more than if he just improved the English score. Improve the stronger areas as well as the weaker areas...that is a great way to reach your Great Goals!


2 edition of Music Expressions Grade 4 Teacher Edition Volume 3 found in the catalog.
2003 by Warner Bros. Publications .
Written in English
|The Physical Object|
Both appearance and content are improved. Students who complete both Algebra 1 and 2, but who do not intend to continue through Advanced Mathematics, will not have covered geometry sufficiently since Advanced Mathematics contains much of the geometry material. The fourth editions have plenty of word problems and real-life applications, but the humor has disappeared. In addition, geometric proofs are taught early in the course then used throughout the first half of the book.
This text moves even further into the theoretical math realm than do earlier Saxon texts. Some student books are hardcover and some softcover. In addition, a Test Analysis Form helps you identify lessons where concepts were originally taught so that students can review if needed for problems they missed. Workbook assignments are directly correlated with each textbook. Originally, Saxon Math took an unusual approach by integrating algebra, geometry, and trigonometry into three textbooks titled Algebra 1, Algebra 2, and Advanced Mathematics.
If your student starts to have more difficulty in the latter part of the course, consider doing only half a lesson each day. It provides elementary school students with the curricular foundation needed for secondary-school music disciplines including band, orchestra, chorus, and jazz ensembles. Every lesson develops critical thinking skills and music vocabulary, and provides cross-curricular connections, assessments, and additional resources for lesson expansion. Teacher Edition Each grade level includes four easy-to-carry volumes.
Handbook of programming languages
Committing to culture
manual for small archives
GCE A Level and special papers chemistry with answers
Roots of rebellion
use of stable activable tracer in hydrology
Research and training programs of the National Institute of Environmental Health Sciences
Good principals or good peers?
A History of Our Lady of the Snow
Environmental law and policy
Marketing and financial control.
The Mouth of the night
Sesame Street Road
Both of these publications help teachers understand the course material and provide suggestions to help you introduce concepts. They complete their geometry requirement with the Advanced Mathematics book.
Originally envisioned as a one-year course, Saxon now recommends that students take at least a year and a half to complete the course unless they are very bright. One of the most significant content changes is the early introduction and frequent use of a graphing calculator with graphing calculator labs.
Once a concept is introduced it is incorporated periodically into the mixed Music Expressions Grade 4 Teacher Edition Volume 3 book that students encounter every day. It covers word problems, scientific notation, statistics, probability, ratios, proportions, simplifying and balancing equations, factoring algebraic expressions, slope-intercept form, graphing linear inequalities, arcs, sectors, and the Pythagorean theorem.
Both appearance and content are improved. These features make this a great choice for many students at this level. Each lesson includes an introduction and explanation of the new concept, examples and practice problems, then a set of problems that not only reinforces the new lesson content but also reviews previously-learned concepts.
While the answer key might suffice, I recommend having the Solutions Manual in case students or parents cannot figure out how to arrive at a particular answer.
Teacher Support Pack At every level, the components of the Teacher Support Pack greatly enhance the curriculum and support instruction within the classroom.
Every lesson develops critical thinking skills and music vocabulary, and provides cross-curricular connections, assessments, and additional resources for lesson expansion.
Over time and through repeated exposure to a developing concept, students gain understanding and mastery.
These generally include math-fact practice, mental math problems, and a word problem. Homeschool kits include a non-consumable student edition textbook, either an answer key or solutions manual, and tests with answer keys.
Also, probability and statistics receive far more attention in keeping with current math standards. Students work with practical applications of concepts through word problems more than we find in many other second-year algebra courses. The Homeschool Kits include the student text, a solutions manual with complete solutions for the Warm Ups and all practice problems, and a Homeschool Testing Book.
Extra math drills for each lesson are at the back of the book.
Teacher Song Book Lesson-specific accompaniments for all "perform-along" songs are provided in this easy-to-use book. The songs include melody line and chord symbols for those who wish to play guitar, autoharp, or piano.
Teacher-student or student-student discussions are an important part of this program. Each lesson focuses on a particular set of music standards set forth in the National Standards Music Expressions Grade 4 Teacher Edition Volume 3 book Arts Education. They would need to use another resource to complete geometry requirements.
Features include embedded assessments, authentic recordings, and diverse content. Note that the third editions have answers to odd-numbered problems in the back of each student text, but there are no answers in the fourth edition textbooks.
This text moves even further into the theoretical math realm than do earlier Saxon texts. The program builds strong problem solving, critical thinking, and computational skills through well-chosen practice problems. Although many eighth graders will have no problem with this book, there are many who will not be ready to begin algebra for another year or two.
The Saxon Math program has tended to be strong on skill development, but weaker on conceptual explanation and application. A significant difference between the two is that the HIGs have a sidebar column that shows assignments complete with answers and often solutions. Its spiral structure builds music skills cumulatively from class to class and year to year.This Smart Notebook document features Lessons of Unit 4 (2-Digit Numbers), Grade 2 in Math Expressions.

Faculty: Bret Benesh, Philip Byrne, Robert Campbell, Sunil Chetty, Arein Duaibes, Robert Hesse, Kristen Nairn, Anne Sinko, Michael Tangredi.
Math Center Director: Brian Nyholm
The mathematics department offers courses to fit the needs of a wide variety of students: the student majoring in mathematics, the student majoring in another field who needs supporting courses in mathematics, and the general liberal arts student.
Since a knowledge of mathematics can be useful in disciplines as diverse as biology, philosophy and economics, the mathematics department offers a number of options to students. The major offerings are flexible enough to prepare students for further study in graduate school, for a career in secondary education, for a career as an actuary or data scientist, or for a career in business or industry. A student majoring in another discipline may choose to minor in mathematics. A major in elementary education may choose a minor in mathematics or the concentration designed especially for elementary teachers. (See the education department listing for more information.)
In addition to the formal courses described below, there are many other opportunities available for students interested in mathematics. An individual learning project on a topic of mutual interest can be designed with the assistance of a faculty member. The department supports students to engage in summer research in mathematics and related mathematical sciences, through a generous stipend program. Opportunities are available to combine the summer research with a Distinguished Thesis. An active student math club and a local chapter of Pi Mu Epsilon (a national honor society for students of mathematics) cooperate with the mathematics department to offer a rich program of seminars, films, visiting speakers, career information and social activities. Each spring the department hosts a regional Pi Mu Epsilon conference at which students and faculty from several colleges gather at Saint Benedict's and Saint John's for two days of presentations by students and invited speakers.
Each semester, the mathematics department employs students paid on an hourly basis as calculus teaching assistants, course assistants, and tutors. Calculus teaching assistants grade papers and, in consultation with the course instructor, supervise the calculus labs. Those labs, which meet regularly, provide students with additional opportunities to discuss course material and to practice problem-solving skills. Course assistants grade papers for lower division classes other than calculus I and II. Tutors give individual help to students at the Math Center.
Mathematics in the Integrations Curriculum
Mathematics, both as a skill and as a theoretical structure has played a crucial role in modern civilization and the everyday lives of individuals. Therefore, all students will be required to take and pass one course which satisfies the common curriculum requirement in mathematics, and students may opt to take a mathematics course to fulfill the Abstract Structures requirement for the Integrations curriculum. While different courses cover different topics, all courses meeting the requirement stress mathematics as a conceptual discipline and address its contemporary role. These courses will also enable students to understand and appreciate the power and limitations when using mathematical reasoning, its language, and notation to solve a variety of problems from other disciplines and from everyday life. Students enrolled in our courses are actively involved in doing mathematics.
We offer two 2-credit support courses for students who would prefer a review of mathematics. Students who wish to eventually take calculus will take Math 115, and most other students will take Math 111 if they wish to review material.

Data is qualitative if words, groups and categories represents the observations or measurements.
Example: colors, yes-no answers, blood group. Quantitative data is discrete if the corresponding data values take discrete values and it is continuous if the data values take continuous values. Example of discrete data: number of children, number of cars.
Example of continuous data: speed, distance, time, pressure. Introduction to Statistics What is Statistics? Statistics is a mathematical science including methods of collecting, organizing and analyzing data in such a way that meaningful conclusions can be drawn from them. In general, its investigations and analyses fall into two broad categories called descriptive and inferential statistics.
Learning statistics with jamovi – a free introductory statistics textbook
Descriptive statistics deals with the processing of data without attempting to draw any inferences from it. The data are presented in the form of tables and graphs. The characteristics of the data are described in simple terms. Events that are dealt with include everyday happenings such as accidents, prices of goods, business, incomes, epidemics, sports data, population data.

Inferential statistics is a scientific discipline that uses mathematical tools to make forecasts and projections by analyzing the given data. This is of use to people employed in such fields as engineering, economics, biology, the social sciences, business, agriculture and communications.
Introduction to Population and Sample A population often consists of a large group of specifically defined elements. All tests will be taken as scheduled, unless prior arrangements are made, with at least 48 hours of advance notice. I, and only I, have the right to agree to giving a makeup test.
The quizzes will either be announced or unannounced. The three tests will take place during the regularly scheduled class time on the following dates.
The plan is for the tests to last 60 minutes, most likely at the beginning of class. The students are expected to stay for the rest of the class. I might change this if it is not working The quizzes will cover material since the previous quiz. I will try to be as straightforward as possible with regards to the material covered over the quizzes and tests.
Introductory Statistics for Psychology - 1st Edition
The most common examples of gaining points but not limited to are through the quizzes, tests, extra-credit problems, and class participation. The most common examples of losing points but not limited to are not taking a quiz or test, and an unsatisfactory attendance record. If a student misses 2 classes, the instructor has the right to drop the student's course grade by one letter grade.
The official gradebook will be kept by the instructor.


Thank you all for your nice comments on Wisteria and for the tips. I'm going to keep working on it and will let you know how it goes.
This is just a quick post to wish you all a happy Pi Day. For those less geeky than I and not already familiar with the "holiday", Pi Day occurs on 3/14. Pi is the ratio of a circle's circumference to its diameter, and today serves as a convenient reminder to think about how important this number is.
For knitters, pi allows us to estimate how much yarn we need in doing a long-tail cast-on. If you visualize a knit stitch as basically a circular loop (more or less), then the amount of yarn needed to form the loop (its circumference) is about 3 times the width of the loop (its diameter). So if you are casting on for a piece of knitting that is going to be 10" across its width, you can estimate that you'll need a bit more than 30" of yarn to cast on. Of course, you'll need a some more for the tail itself, especially if you plan to use it to seam, but the "3x" rule is a good starting point.
Since pi is a constant, when the diameter doubles, so does the circumference. If you've ever knit some variation of EZ's pi shawl, then you've put this to good use. This is the reason that if you doubled your stitch count on row 3, then you'd do it on row 6, then 12, then 24, and so on! Sometimes when you knit a circle, the pattern will have you increase your stitch count more subtly, by tucking in a smaller number of increases on every round or every other, instead of doing them spaced out so far apart, but if you wrote out the stitch counts for each row, you'd see that this same relationship is maintained: double the row number, double the stitch count.
I am anxious to start working on a circular project of my own, but it's still percolating in my head. I'll be sure to show you if something comes of it.


Formal definition of derivatives a short explanation
Note: I’m trying something new, while I’m learning new concepts, I will try to use the Feynman technique to cement my learning and share the explanations with you. Hopefully, some of these explanations can prove helpful in your learning journey.
We can turn derivatives into limits.
Here we have an example graph:
Before finding the slope of a. We can work out the slope of the general function. The plot x and x + h.
h is an arbitrary small number that can be adjusted as h approaches 0.
2 x’s cancel out in the numerator.
As h approaches zero to get the slope we can write:
Which equals f’(x)the derivative of f(x).
Now we can use the a point from earlier. We can work out the derivative of a by just plugging in the point.
Now we have made a tangent line when x=a.
Now what happens if you don’t care about slope of the function and you only care about getting one point?
You can use an alternative form below:
In visual form:
As we can see we have a tangent line between a and x.
instead of h getting smaller we have x getting smaller and getting closer to a.

Latent variable models have been widely applied for the analysis and visualization of time series that result from techniques in experimental neuroscience. These are datasets in which the evolution of the observations is relatively smooth and possibly nonlinear. In this work we present Variational Inference for Nonlinear Dynamics (VIND), a variational inference framework that is able to uncover nonlinear, smooth latent dynamics from sequential data. The framework is a direct extension of PfLDS; including a structured approximate posterior describing spatially-dependent linear dynamics, as well as an algorithm that re- lies on the fixed-point iteration method to achieve convergence. We apply VIND to electrophysiology, single-cell voltage and widefield imaging datasets with state-of-the-art results in reconstruction error. In single-cell voltage data, VIND finds a 5D latent space, with variables akin to those of Hodgkin-Huxley-like models. The quality of VIND’s learned dynamics is further quantified by using it to predict future neural activity. VIND excels in this task, in some cases substantially outperforming current methods.


When learning to drive, one of the biggest things to remember is the stopping and the breaking distances of the car you are driving.
To be behind the wheel without knowing or being able to remember the distances can be extremely dangerous, not just to yourself and your passengers, but to others on the road too.
At Wimbledon Driving School, we recognise this and feel it is important to point out how to remember the calculations to everyone who learns to drive in order to give them the best chance of mastering their driving test.
Firstly we will look at stopping distance. So what exactly is the stopping distance?
Put simply, it is the distance the vehicle covers in the time it takes to react to a hazard, also known as the thinking distance, added to the distance you travel between hitting the break and actually coming to a stop, known as the breaking distance.
This is worked out by taking the speed of the car, adding in a ‘factor’ which is acknowledged to begin at 2 and increase in 0.5 intervals, and multiplying the two together.
If the car is travelling at 20mph with a factor of 2 the stopping distance would be 40 feet (20×2).
If the car is travelling at 30mph the factor would be 2.5 meaning the stopping distance would be 75 feet (30×2.5).
At 40mph the factor would be 3, so the stopping distance would be 120 feet.
50mph has a factor of 3.5 meaning a stopping distance of 175 feet.
With 60mph, the factor is 4 so the stopping distance is 240 feet.
And at 70mph the factor would be 4.5 so the stopping distance would be 315 feet.
Now let us look at the breaking distance. Once again, what exactly is the breaking distance?
The simple equation to work out the breaking distance is to take the stopping distance and remove the thinking distance.
The thinking distance is generally accepted as being the same in feet as in mph, so if the car is travelling at 30mph the thinking distance would be 30 feet, if it is going at 60mph it would be 60 feet and so on.
Putting those figures together, we get the following breaking distances:
20mph = 20 feet
30mph = 45 feet
40mph = 80 feet
50mph = 125 feet
60mph = 180 feet
70mph = 245 feet
For all of the above figures, we must stress they are worked out on dry road conditions. If you want to convert from feet into metres a general comparison would work out at 30 feet to equal 10 metres.
It should also be pointed out that in wet conditions the stopping distances are doubled, and if you are driving in snowy or icy conditions, then the stopping distances could be more than 10 times it would be when you are driving in what would be considered normal conditions.
When learning to drive with Wimbledon Driving School, ensure you have those calculations memorised to give you the best chance of passing your driving test.

BAURU, Brazil – Brazil’s 7-1 defeat at the hands of Germany in Belo Horizonte took players, pundits and fans completely by surprise. In Mathematical speak, how do we put a figure on exactly how shocking the even was? This perhaps flawed attempt to quantify our astonishment at the Brazilians’ thrashing is a cautionary tale for mathematically inclined investors.
Let us, for pure edification, employ an incredibly simple model: it assumes that goals in football follow a “Poisson Distribution”. The Poisson is a statistical staple because it is broadly applicable in the real world: it calculates the chance of a given number of events (such as goals being scored) happening within a specified length of time (such as a 90-minute football match), given the average rate at which those events have occurred in the past.
The rate in this world cup is the average number of goals scored per team per match. In this tournament, after Germany’s shock victory, this was about 1.4 (or 2.8 goals per game), according to the FIFA World Cup records on Wikipedia.
The Poisson distribution does an impressive job of describing the competition so far. The graph below shows how often teams scored a certain number of goals in a match. The bars show the actual results: teams scored zero 33 times, scored a single goal 43 times, and so on.
The total is 122, from the two teams in each of the 61 matches played up to and including the Germany-Brazil game. The dashed lines then show what the model predicts. It looks like a pretty good fit, but for one egregious exception: some team scored seven goals in a single match!
In fact, according to my model the odds of a team scoring seven or more goals in a match are well below 1 in a 1,000 games. So there you have it – a quantified surprise. Like the nation of Brazil, this must be equally shocking in the world of mathematics.
Even more surprising is the level at which this is happening. There are just 64 matches in a modern World Cup, and there have only been 800 matches in the competition’s entire history. This invites an almost philosophical question: how likely is it that, on that night, we genuinely witnessed a 1-in-1,000 game of football, unlikely to be repeated in a World Cup for perhaps a century hence? While it was quite a match, that seems an extraordinary claim.
The alternative is that the collapse of the Brazilian defence wasn’t a once-in-a-lifetime event. Perhaps this simple model doesn’t properly account for extreme events? It has done relatively well on the majority of matches, but a 7-1 thrashing does something fishy to the Poisson’s predictions.
There are myriad explanations, statistical and sporting, for Germany’s incredible seven-goal outlier. One likely contender is that football violates the assumptions implicit in this analysis. For example, the Poisson assumes that every goal is independent of every other goal: it assumes that the likelihood of scoring in any given minute of the match is the same, regardless of whether a single goal has been scored, or six. This seems implausible: Germany’s crowning three minutes, in which they went from 1-0 to 4-0 up in just 179 seconds, were surely not independent.
Perhaps an astounded Brazilian defence, gawping after Germany’s second rapid-fire goal, simply let the next two past? Or did the German team momentarily find and exploit their ruthlessly effective mojo? Whatever the explanation, it seems unlikely those goals were independent of one another.
This is a common problem when using statistical models, and it comes up in another context where the stakes are often higher, especially in the global financial system. Traders frequently use equations and algorithms to determine whether to buy or sell. Often computers will follow mathematical models automatically, trading thousands of times per second – far too fast for human oversight.
These algorithms run into similar issues as seen here. For example, a financial model might assume that the prices of certain stocks, currencies or commodities are more independent than they really are. As the financial system becomes ever more complex and interconnected, this kind of assumption makes it increasingly likely that models will ignore the kinds of extreme events we saw in Belo Horizonte, or during the 2007 financial crisis.
It’s even plausible that naive application of mathematics can contribute to modern financial crises.
For example, the widely-used Black–Scholes equation notoriously only works under conditions where market movements are marginal. In the real world, large shifts in stocks happen more often than the model predicts. Since so many investors make use of Black–Scholes and related models, shocks can affect the whole market and contribute to systemic collapse.
Similarly, there have only been a handful of financial crises interspersed in decades of regular trading, which makes it hard for banks and regulators alike to know when it’s safe to let traders make bets guided by equations.
In addition, this model doesn’t have to be certain at all times, presumably because all the teams at the World Cup are put through a rigorous quality control system, also known as World Cup Qualifiers, where nearly all 200 odd nations on Earth participate. This goes a long way to ensure that the 32 teams that arrive at the World Cup finals are of a comparable standard. Even then, the worst teams won’t play more than 3 matches, meaning they are less likely to buck the trends in the Poisson model.
The biggest problem here is the very rarity of extreme events. While this simple model is clearly broken, it is very hard to fix it: the German result is totally unprecedented in a World Cup semi-final, which makes it tricky to choose between the many subtly different mathematical explanations that might account for it.
The only sure thing, in footie or finance, is that extreme events are here to stay. In the World Cup, they just add to the excitement; for investors and regulators, taming this uncertainty could be the most important challenge facing the financial system.
This mathematical model suggests the Brazil-Germany result was a once-in-a-lifetime World Cup scoreline, but the Mathematics may be terribly wrong. In the end it was a shock, whatever way you might slice and dice it.


Mathematics is considered one of the most important subjects for students right from an early age. It not only enhances their logical capabilities but also opens up various career possibilities later on. It is also one of the highest-scoring subjects so much so that students who perform well in mathematics increase their chances of better performance in academics overall. For the same reasons, teachers and parents often encourage students to take interest in mathematics, but a lot of times, mathematics can turn out to be a real headache for some students.
Being a subject that is highly objective wherein either a question is either right or wrong with no possibilities in between, mathematics is a subject that demands a clear rational and logical approach which also makes understanding this subject quite a task. However, this is not to be assumed that to understand this subject one needs an extraordinary brain. It is quite likely that a student may start liking this subject with proper guidance and a good strategy in place. If students start from an early grade level such as Class 5 in the right direction, they can go on to develop quite strong and reliable foundations in this subject, helping them ace in mathematics later on academically. Here are such tips that can help students of Class 5 to score good marks in mathematics, that too in a short period.
- Start from the basics
As already mentioned, mathematics is a subject that demands a complete and clear understanding of the concepts without which solving problems will be impossible. To score well, make sure that student knows the core idea of a concept well. Inculcate thinking and analysing, not memorising. Teachers/mentors can also encourage students to explain concepts that they have studied to their classmates which will allow them to reorganise the understanding of that particular concept in their minds in a way that is best suited for them. Remember, well-understood basics go a long way.
- Have a clear idea of the syllabus and the paper pattern
One of the most important aspects of preparing a subject from an exam-centric point of view is having a clear understanding of the syllabus and types of questions asked. Teachers/mentors can help students understand the syllabus in simple terms in a way that prepares them for the demands of the subject. Instead of simply reading out the topics and subtopics, it will be advised that students are provided with a holistic view of the syllabus which connects various topics. It will allow them to have a coherent understanding of the subject.
- Highlight formulas and related concepts for quick revision
Mathematics is a subject based on formulas. One of the most common problems that students face in maths is that they don’t remember formulas and related concepts. Thus, it is highly recommended that students are encouraged to highlight such formulas in a way that comes in handy during last minute revision.
- Practice, practice and practice!
In a subject like mathematics, practising as many problems and questions as one can is the most crucial piece of scoring well. A lot of books available in the market already include an ample amount of questions for students to solve which familiarises them with the variety of questions that can be asked in the exam. NCERT Books for Class 5 Maths are one such example of a great learning material that contain a variety of sample problems, also with easy and understandable solutions for students to take help from. Teachers/mentors, from their side, can also help students in maintaining the habit of the rigorous practice of solving questions for every concept by using as many sample problems as they can during teaching a particular concept.
- Begin with easier topics
Managing the order of studying various topics can also create a huge difference because when students start with easier topics that they grasp well will encourage them to take on relatively more challenging topics. It will also increase their self-confidence and positive attitude towards the subject.
- Group study helps
Teachers/mentors can create small study groups for their students wherein every member can help each other with individual doubts and shortcomings. This goes on to inculcate the feeling of competitiveness among students who will work harder to strive for better results.
- Make use of Flashcards/online learning tools
For all those tech-savvy teachers/mentors out there, there are a wide variety of online tools available which allows them to create interactive worksheets and lessons for students which not only makes the subject much more understandable but also interesting and fun to learn. Tricks like making flashcards for important formulas allow students to do a quick revision before the exam.
- Connect with real-life applications
Studying a subject without underlining a clear understanding of its real-life applications can be quite confusing and challenging, especially true for subjects like mathematics. Hence, to make students score better in maths, they should be explained each concept along with its real-life application. This will help them memorise the actual idea behind formulas and concepts they are learning which will boost up their problem-solving capabilities.
- Review errors
No preparation for a subject gets completed without the final analysis of strengths and weaknesses in that particular subject. Teachers/mentors should help students in understanding their weak areas and common errors which is a first step towards rectifying those errors. For this, they can have regular assessment sessions wherein each student is made aware of topics that they need to put the effort into.
- Time management
Last but not the least, for every student to fare better in any field, he/she must be efficient in managing his/her time. This becomes even more crucial when exams are just around the corner and they need to prioritise which topics to read more on according to their relevance in final exams.
In conclusion, mathematics is not a subject to be mugged up just before final exams but is the one that is to be learned over some time. Nonetheless, by making use of the tips mentioned above students of Class 5 and even beyond can increase their chances of better score fairly well.


The Lotka-Volterra equations are a pair of first order, nonlinear, differential equations used to describe the interaction dynamics between two species of organisms that have a predator-prey relationship. Despite the name, this set of differential equations was independently introduced two mathematicians, Alfred J. Lotka in 1925 and Vito Volterra in 1926.
Although these two mathematicians produced identical equations, the underlying assumptions behind these equations differed. Lotka’s version of the Lotka-Volterra Model assumed that as long as the population of species remain within the logical neighborhood of equilibrium point of the system, these populations of organisms will eventually become self-sustainable: reaching a constant state. However, since these neighbor regions were hard to estimate, and the parameters of his equations were not defined by system wide constants, the applicably of Lotka’s assumptions were greatly hampered. On the other hand, Volterra’s assumptions of the Lotka-Volterra Model resolved this issue by using parameters that were derived by global constants with defined biological meaning, these parameter generated could be generally applicable to estimate periodic and chaotic cycles of any populations that have prey-predator relationships.
Ever since the introduction of the Lotka-Volterra model in the mid 1920s, this set of differential equations has seen an increase in application by the biological world. Other than estimating the interactions dynamics between predator-prey, these equations were also used to describe other similar interaction relationships such as the host-parasitoid relationship as well. In response to the increase in applications, were modifications to the equations that made this set differential equations become more realistic by inserting limiting functions such as logistic growth functions and mass action functions.
The most significant impact of the Lotka-Volterra equation is that this was the first attempt by mathematicians and biologist to use seemingly simple mathematical equations to model the interaction dynamics between two species of organisms. Despite the simplicity in their underlying assumptions and estimation of parameters, the results estimated by this set of differential equations nevertheless correlated closely to real life observations of those species in their natural habitat.
The system of differential equations of the unmodified Lotka-Voltera model in their dimensionalized form,
characterize the simplest way to describe a predator-prey relationship. N represents the number of prey and P represents the number of predators. and represents the growth of each respective population against time. The differential equation for prey population change is equal to exponential prey growth minus the rate at which the predator captures the prey, i.e. Holling Type I functional response . The term rN, which characterizes the exponential prey growth, assumes that there is an unlimited supply of resources for the prey to utilize. The term cNP, also called the Holling Type I functional response, is considered a mass action term describing predator-prey encounters. It predicts a linear relationship between the prey and predator. Lastly, the differential equation for predator population is equal to the predator growth minus the rate of predator death.
In order to do a mathematical analysis of this system of equations the non-dimensionalized form of the equations can be used:
The steady states for this system of equations are found to be: (0,0) and (1,1) . The Jacobian matrix is:
Plugging in the steady states into the Jacobian allows one to determine the stability of the steady states. The Jacobians that result from plugging in the steady states (0,0) and (1,1) are:
Finding the eigenvalues from each Jacobian will allow us to determine the stability of the respective steady state. The eigenvalues for J(0, 0) are :. The opposite signs of the eigenvalues inform us that at the steady state (0,0) we have a saddle point.
The eigenvalues for J(1,1) are : . Since the real part of both eigenvalues is zero, it is determined that at (1, 1) the steady state is neutrally stable. The neutrally stable spiral is meant to represent the periodically oscillating prey-predator population. However, it is inadequate because of its structurally unstable center. Any slight deviation from this steady state and the system (population) goes into chaos; the system is stable only for specific conditions.
Overall, due to the fact that this system of equations assumes exponential growth for the prey, a Holling Type I functional response, and a neutrally stable steady state, this model is not a reliable or realistic characterization of prey-predator interactions. It must be altered in order to realistically depict the periodic oscillations of prey-predator populations.
Modifications to the Model
The original Lotka-Volterra model assumes exponential growth of the prey population. This means that the prey population will continue to increase over time with the absence of predators. However, in natural populations, the prey population will not keep increasing in the absence of predators. The number of resources available in the area limits the populations. A given niche can only support a set number of individuals, called the carrying capacity. To make the model more realistic, a logistic growth was used in place of exponential growth. That is, the prey population levels reach a carrying capacity when predators are absent. The Lotka-Volterra model using logistic growth is shown below:
To find the steady states and stability of the Lotka-Volterra model with logistic growth of the prey population, the nondimensionalized form of the two equations are used:
The steady states are then (0,0), (1,0), and (α,1 − α), where α is between (0,1).
The Jacobian is given by the partial derivatives with respect to x and y at f(x) and g(x), where
f(x) = x(1 − x − y)
g(x) = β(x − α)y
and it is
For (0,0), the trace is 1 − βα and the determinant is − βα. Because the determinant is always negative, a saddle point exists at (0,0).
For (1,0), the trace is − 1 + β(1 − α) and the determinant is β(α − 1).
When α > 1, the determinant is less than zero, and the trace is less than zero, so (1,0) is a stable state.
When 0 < α < 1, the determinant is greater than zero, and (1,0) is a saddle point.
For (α,1 − α), the trace is − α and the determinant is αβ(1 − α).
Because 0 < α < 1, the determinant is always positive. However, the trace is always negative, so (α,1 − α) is stable.
Thus, with the logistic growth model, the Lotka-Volterra model loses its neutrally stable state and for 0 < α < 1, the population levels of prey and predators sinks to (α,1 − α), while for α > 1, the population level of prey goes to the carrying capacity, and the predator becomes extinct.
The functional response refers to the relationship between prey and predator. It describes the relationship between the density of prey in a region and the number of prey consumed by the predators in the region (Wikipedia. "Functional Responses"). There are three main types of functional responses.
The Type I functional response is the original assumed relationship between predator and prey interactions. Type I assumes a linear relationship between the number of prey in a region and the number of prey consumed. That is, the number of prey consumed by predators is directly proportional to the number of prey in a region. Under the original exponential growth Lotka-Volterra model, a neutrally stable state is found, while under the logistic growth Lotka-Volterra model, a stable node indicates the long term stability of the model.
This functional response is not very realistic because it is unlikely that predators will at larger population levels begin to kill and consume an infinite number of prey. While there may be a relationship at first, predators are limited by the time it takes to hunt and kill the prey, so at a certain prey population level, predators will likely not be consuming more prey with a spike in prey population levels. Holling devised two alternate functional responses to describe the rate at which the predator consumes prey in a region: Holling Type II and Holling Type III.
Holling Type II Functional Response
One way to improve the Lotka-Volterra Model is to include a more realistic functional response. The rate at which predators capture prey can be modeled as a hyperbolic function that saturates due to the limited time that predators have to search for prey. At some point, increases in prey density will have no effect on the amount of prey caught by predators. The following is a derivation that uses the time it takes to handle prey (Kot, 2001):
T = total time
Th = handling time for each prey (time it takes to eat)
N = number of potential prey
V = number of prey caught
Assuming that the number of prey caught (V) is proportional to the number of potential prey (N) and time spent searching (T-VTh),
V = αN(T − VTh) , where α is the proportionality constant.
If solved for V, the equation becomes
This equation can be re-written into the Michaelis-Menten form as
Incorporating the Holling Type II Functional Response into the logistic growth model yields
The non-dimensionalized forms of these equations are
The x-nullclines are:
x = 0 and
The y-nullclines are:
y = 0 and
The steady states are:
(0,0), (γ,0), and ,
The stability of the steady states can be summarized in a bifurcation diagram plotting x against γ.
The emergence of periodic solutions when γ = 3 suggests that the addition of the Holling Type II functional response into the logistic growth Lotka-Volterra model yields more biologically realistic solutions.
Holling Type III Functional Response
Holling Type III improves the modeled predator-prey dynamic in type II, and models the consumption rate, φ(t), as a sigmoid. Similar to the behavior exhibited in type II, the consumption rate φ(t) asymptotically approaches a steady state value for large prey density. At low prey density, the predatory consumption rate is modeled as exponential growth. This relationship is a function of predator learning time and prey switching. (Wikipedia. "Functional Responses"). A type III functional response takes the form
where φ is the consumption rate and N is the prey density . (Kot 2003).
At low prey density, the prey is scarce. Predators are unable to learn the eating, habitation, and other habits of the prey species. This inability to learn due to scarcity causes relatively inefficient predation, and the consumption rate is reduced. At higher prey densities, the prey is available in numbers abundant enough that the predator species is able to learn how to effectively hunt the prey. Predation becomes more efficient, and the consumption rate increases.
Predator species that are not tied to the specific prey under consideration have incentive to switch to alternative prey sources if the modeled prey density is low. Since the prey is harder to find, predators switch to other, more abundant prey species, causing the consumption rate to drop. High prey densities remove the incentive for predators to switch to other prey species, causing the consumption rate to increase until reaching steady state.


Can you even believe it is January!? We missed almost an entire week of school for snow so January just flew by! We will be making up for those missed days all of second semester so get ready! I have posted a geometry video on quadrilaterals for you and your kids to watch in our Math Lessons: Geometry section so take a few minutes to check that out. Also, the February newsletter has been posted and there are lots of reminders and important information there. Please be sure to read it carefully and mark your calendars as needed. Finally, we will be passing out Valentines on Friday, Feb 14. I have posted a list of kids' first names under our "Newsletters and Info" tab so please be sure to send in a Valentine for each student on that day if you choose to participate. Thanks for everything and Stay Warm!
I'm Mrs. Keleher! I love teaching 2nd Grade!


Today is the day, Peeps, when I figure out how much money I will pay myself for running. What?
I got this idea from a blogger several years ago (I wish I had remembered her name so I could credit her!), and I like it for two reasons:
1. It helps me justify the money I spend on running.
2. It's a great incentive for putting in more miles.
How does Payday work? Let me show you.
First, keep track of your yearly miles using any tracker tool you like. I like Dailymile.com because I can embed the widget in my blog that shows my weekly, yearly, and total miles.
Next, keep track of your racing miles and PRs. Athlinks.com is a good source for this information.
Then, decide how much money you think your activities are worth. I decided that for each mile I run, I will pay myself $.50. For each racing mile, I'll pay $1.00. Every PR gets me a $5.00 bonus. To keep it fair, I have to subtract racing fees, including babysitting. I don't add up my racing gear, but I know some people do. Let's try it, shall we? Oh, before we do, you need to know that I am not a math whiz.
Let me know if I made any mistakes:
2014 miles: 1,039
-race miles: 84 (rounded from 83.8)
2014 miles: 955 x $.50 = $477.50
+race miles 84.00
+ PR bonuses ($5 each) 40.00
Looks good so far, right? Now I have to deduct racing fees and babysitting. Ugh.
2014 racing fees: $235
+ babysitting $200
Last bit of math, Peeps. Stay with me here.
2014 miles: $601.50
-fees : $435.00
Whew! We made it! You get an A+ for seeing me through all of these numbers!
Any year that I can break even, or even make money, is a good year for me! But wait, Stephani (you say), aren't you paying yourself with your own money?! How is that even worth it? Good question! The way I see it, I don't often credit myself with things I do successfully; more often, I dwell on areas where I fall short. This system forces me to see my successes and reward myself for them. It's the equivalent of putting a penny in a jar every time you say something nice or do a good deed. At the end of a year, you look at the pennies (even though they ultimately came from your pocket), and you see the progress.
You don't even really have to pay yourself; you could use gold stars, or you could just do the math as a point system. I put the money in a tiny savings account I have set aside for this purpose. When there is "enough" money there, I will use it to splurge on a vacation, maybe. A race-cation. Paris Marathon, I'm looking at you.
|This is EXACTLY how I will look running along the Seine!|
The point is this: reward yourself for what you have accomplished. Find a way to recognize and celebrate your success. You have worked hard, and you deserve it, Peeps.
Here's to earning more in 2015!

My lovely friend brought me Starbucks this morning. Cause she loves me and knew it was going to be a long day of work and school for me. So sweet. As we were sitting having coffee and chatting Corbin my sleep giggler decided he to do some math.
C: Nine minus two equals seven!
Z: Corbin! What are you doing?
C: Math. (As he is removing the eggs from the container and putting them on the kitchen table.)
Z: Math with eggs might get a little messy!
C: I'm hungry and I'm doing math.
Me: I guess you want eggs for breakfast.
Apparently he was hungry enough to get the eggs out of the refrigerator while I wasn't looking and count how many eggs he wanted to eat and how many were left. I'm so glad my mom had them the rest of the morning. Hee Hee.


The relationship definition defines a relationship to be a union among two specific sets of people, whether they are enthusiasts or blood relatives. Definition for a marriage may also add a marriage in certain regions. It might be essential to understand that the relationship meaning does not pertain to detrimental unions or perhaps marriages. The relationship may also be between a parent and a child or between a spouse and a partner within a civil union. There are additional varieties too.
A marriage definition generally specifies the quantity of links feasible between parent and offspring, between littermates, and among parents and their rejeton. The cardinality of a relationship could possibly be called the generation quantity or it can be called the ancestral romance number or it may be referred to as the genealogical number. For example , the relationship description «child of x» identifies a set of back button ancestors. Through this example, there is as many descendants as there would be parents and either the fogeys or their particular descendants would have been delivered within the chosen generations.
To ensure one to manage to specify the cardinality of an relation, they have to identify every single generation, which can be usually done by use of terms such as era, ancestor, and rejeton. It is very simple to ascertain the cardinality of an set of contact on the basis of it is set of primitive and rejeton relationships. As an example, in a set of ancestral relationships, it is easy to ascertain the cardinality of father-son, daughter-son, mother-daughter, and so on. By use of these types of terms, one can easily determine the number of generations where a set of relationships belongs. This method is often used by genealogical research.
On the other hand, it is also possible to stipulate the cardinality of a pair of relations based on its pair of predecessor human relationships. The group of predecessors of any set of relations can be specific by by using central bifurcation. The theory of central bifurcation initial arose in mathematics when ever Dedekind utilized the mixture of sums of squares to acquire the sums of most elements of a huge field, particularly a set of substantial numbers. The results of the procedure provided rise for the axiom of several numbers and theorems of arithmetic. Theorems of arithmetic are traditionally used in research and in a large number of fields of mathematics.
A relationship classification can also be specific using hotter means. These means consist of integral remedies onebeautifulbride.net website and finite dissimilarities. An integral solution is a formulation whose solutions are capabilities that are themselves functions. A finite difference is a group of points (or segments) on the curve. In cases of bifurcation, the definition of the relationship is given by set of dissimilarities that are tangent to the interval of the pair of components, while a finite big difference calculus has by the group of differences that are parallel towards the interval.
A relationship definition can also be particular using algebraic means. Therefore either of two factors can be specific as a solitary worth (i. elizabeth., x+y=0), or that both variables could be specified as complex (x+y=both y and z). The selection between algebraic means and real world which means is consequently largely an issue of traditions. In general, however , a romantic relationship is easier to define once both variables are actual or rational and when their very own values are known to each and every one individuals mixed up in calculation. In cases of irrational info, the definition much more difficult because one particular must consider the effects of variance on the approximated value on the relationship. Similarly, the presumption that romantic relationships between variables are self-sufficient of one one more is an important basic principle that must be borne in mind when working with non-independent data.

And why isn’t any multiplication, subtraction, and division also posted? I like math, but there is something really confusing going on at Youtube… unless I’m missing something.


Not easy to draw legislative districts
September 23, 2021
