The Social Graph of a Famous Mathematician
Above is the social graph [a.k.a. social network map] of Paul Erdõs. He was an expert in the mathematics of networks. Erdõs practiced what he preached — he was a weaver of social networks and thus a builder of social capital.
Erdõs was known for traveling the world and collaborating with mathematicians on problems and proofs he found interesting. Many scientific papers resulted from these intense face-to-face collaborations. Erdõs had 507 co-authors, some of whom collaborated with each other. Erdõs’s partnerships exposed the social structure of scientific discovery. An excellent mathematical analysis — Evolution of the social network of scientific collaborations[PDF] — is available from Laszlo Barabasi and colleagues.

For instance, she referred to "maths" as "maks." If only she knew that in the US, it was not even maths but math; I wonder how she would have pronounced "math."
The self-appointed spokesman for the "Queen's English" often harasses me for my American spellings, way more than the trouble I gave my grandmother. So, what is the deal with maths v. math, right?
Americans and Canadians tend to say math while Brits and Australians opt for maths.
The welfare queen, er, Her Majesty, might think that maths is the correct contraction for mathematics. Not so fast:
In the 17th century, English speakers fell under the spell of a peculiar linguistic fad. With some exceptions, they started to use a seemingly plural form of a field of study to refer to it in the singular. Enter physics, acoustics, economics, acrostics. The rule wasn’t applied uniformly: Disciplines that had been around for a while, such as arithmetic, had already rooted deeply enough in people’s minds to avoid the trend. But mathematic, the classical and somewhat arcane science of all things numerical, acquired an S.
Are you thinking what I am thinking after reading that? "What the hell is acrostics?" If you are "puzzled" then go figure that out yourself; I Do It Only Tuesdays!
Where was I? Yes, about mathematic.
Math as an autonomous term for mathematics came first to the United States, in 1890.
So, what about in Britain?
The British maths cropped up in 1911, and both terms leapt in usage for their respective countries during the second half of the 20th century.
Wait, so all these mean that there is no damn logic in why and how usages like math and maths developed?
Really, though, fate and chance factor into linguistic trends as much as anything. It only takes a few solemn Oxford whizzes talking about maths before much of London catches on, and then Australia, and then … you do the maths.
Which means if there were enough people like my grandmother, then we might have as well ended up with "maks"? Well, you do the math! ;)
PS: remember how 2+2 =5 in 1984?

One of my all time favorite books is The Very Hungry Caterpillar. When we read this book during our Spring Toddler Theme, Sicily was showing a strong interest in counting.
I decided to test out her signs of readiness as an invitation related to The Very Hungry Caterpillar.
I made pictures of all the food the caterpillar eats. I laid them out on the floor lined up by the amount he ate with a wooden number on top of each row. I placed the junk food he ate on the floor as well, but I didn’t add a number to it.
I also added the butterfly life cycle pictures for a discussion.
We started the activity by reading the book. She noticed the butterfly picture right away after reading, so we spent time talking about the life cycle and matching the pictures to the ones in the book.
I pointed out the numbers. As I pointed to each number, I said “This is the number 3″ and traced it with my finger. She decided to copy what I was doing.
We talked about how each number represents how many of each fruit the caterpillar ate. I pointed to each number again, said the name, and traced it. This time we counted each fruit.
When we finished, I sat back and let Sicily explore the invitation in her own way.
She lined up all the pictures and started counting…”1…2…3…1…2…3.” She only knew how to count to 3 by herself, so she just kept repeating. When she got to the end of the line, she was so excited.
Even though she didn’t count the “right” way, she was still getting valuable counting practice. Eventually, she will notice there are more than 3 numbers and begin counting higher. This is where the encouraging environment comes in.
Now that she is interested in counting, I’ll add more activities like this one to encourage her to learn more about counting and numbers.
During this activity, Sicily was honing her skills in counting, number recognition, one to one correspondence, classification (lining them up), and hand-eye coordination. She also got some science discovery with the butterfly life cycle.


Terminal velocity depends on atmospheric drag, the coefficient of drag for the object, the (instantaneous) velocity of the object, and the area presented to the airflow. If it takes 9.9 seconds for the object to hit the ground, its velocity is (1.01 s)*(9.8 m/s^2), or 9.9 m/s. Multiply feet per second by 0.68 to find the object's velocity in miles per hour. For example, if you’ve been given a time (usually in seconds), then the velocity of any falling object can be found with the equation v = g * t, where g is acceleration due to gravity. Calculate the maximum height. Required inputs are: the mass of the falling object/body, the drag coefficient and the projected area, as well as the air density and gravitational … The formula for finding average velocity is: A car starts at position x = 16 feet. It is a position function. For example, 483 ft^2/s^2 * 2 = 966 ft^2/s^2. As calculus is the mathematical study of rates of change, and velocity is the measure of the change in position of an object with respect to time, the two come in contact often. If you are at the surface of the earth the acceleration is g = 32.2 feet/sec 2 or 9.8 meter/sec 2.Integrating the acceleration once gives V = V o + g T where V o is the initial velocity, presumably zero, and T is the time of fall. Gravity will accelerate a falling object, increasing its velocity by 9.81 m/s (or or 32 ft/s) for every second it experiences free fall. What is the car’s average velocity? Setting h(t) = 0 gives: Step 3: Insert your answer from Step 2 into the function from Step 1: The velocity is 113.28 feet per second when the book hits the car, which is more than 100 feet per second. Ascertain the height from which the object fell. For example, if the velocity of the rock is calculated at a height of 8.10 m above the starting point (using the method from Example 1) when the initial velocity is 13.0 m/s straight up, a result of ±3.20 m/s is obtained. The car traveled from 16 feet to 134 feet (134 – 16 = 118). You know the function from Step 1. Example: at a straight jump from a ten meters tower, the jumper's center of gravity is about 11 meters above the water. If you are supplied an initial value, you can find the constant by setting time equal to 0. The sign of the function tells you the direction the object is traveling. d/dt 4t2 + 4t + 4 = 8t + 4 See: Integral Rules. Apart from the last formula, these formulas also assume that g negligibly varies with height during the fall (that is, … Take the square root of the previous result to calculate the velocity when the object hits the ground. In other words, you need to integrate the function. The total time taken by the object to reach earth is measured and entered in the speed of falling object calculator. If the mass is m = kg, then the kinetic energy just before impact is equal to K.E. Step 2: Solve the position function for zero (in other words, when the height is zero) to find out when the book will hit the car. The equation v = S/T gives you the average velocity of an object, given distance and time. It tells the speed of an object and the direction (e.g. Gravity accelerates you at 9.8 meters per second per second. If the object fell from 5 m, the equation would look like this: (2*5 m)/(9.8 m/s^2) =1.02 s^2. Male or Female ? In this example, we will use the time of 8 seconds. The Practically Cheating Calculus Handbook, The Practically Cheating Statistics Handbook, 2. Step 2: Perform integration on a(t). Your first 30 minutes with a Chegg tutor is free! Example problem: Frustrated with your calculus class, you throw your textbook out of your dorm window, which is 200 feet above your car in the parking lot. 1. Step One:Find the difference between the initial and final positions of the car. The general gravity equation for velocity with respect to time is: Since the initial velocity vi =0 for an object that is simply falling, the equation reduces to: where 1. vis the vertical velocity of the object in meters/second (m/s) or feet/second (ft/s) 2. g is the acceleration due to gravity (9.8 m/s2 or 32 ft/s2) 3. tis the time in seconds (s) that the object has fallen Velocity of a falling object as a function of time or displacement Example: Deflection of a Falling Object. This free fall calculator determines the velocity and the time of fall of a body falling to the Earth or another planet in a vertical direction if the height is known. a(t) = 10t + 5 The above equation can be used to calculate both impact force of a falling ojbect as well as impact force of a horizontally-moving object such as in a car crash or plane crash. If you are able to time how long it takes the object to fall, simply multiply that time by the acceleration due to gravity to find the final velocity. There are a few conceptual characteristics of free fall motion that will be of value when using the equations to analyze free fall motion. It must also meet the requirements for being a function. These equations do not apply to objects dropped from very high up, because such objects will reach a terminal velocity before they hit the ground. Take the square root of the result to calculate the time it takes for the object … For example, v(t) = 2x2 + 9. Gravity will accelerate a falling object, increasing its velocity by 9.81 m/s (or or 32 ft/s) for every second it experiences free fall. The acceleration due to gravity is 32.2 ft/s^2 for English units, or 9.8 m/s^2 for SI units. Enter one value at height, time and speed, the other two values will be calculated. If we drop an object from height , the effect of the centrifugal force is already in the local value and local direction of .The Coriolis force is not included and it is proportional to velocity so it will not affect the direction of plumb bobs. Change in potential energy =mgh Once the object hits the beam which is pivoted at the centre and gets attached to it. So let's try it out with some numbers. Yes, there will be a dent! You can differentiate it (i.e. The calculator will determine the final velocity and total height the object was dropped from. Plot this against height on a new graph. with rectiliear motion), you can use the sign to tell you whether the object is speeding up or slowing down: Watch the video for an example of to use the function to find total distance traveled. (Y axis: velocity; X axis: height fallen.) If it were constant, it would not have the variable in it, and it would also have an acceleration of 0. She holds a Master of Science in agricultural engineering from Texas A&M University. Integration is a somewhat advanced calculus method, so be sure to take a look at the articles specifically detailing it (see: Integrals) if you are unfamiliar with it. The book will dent your car if it’s going more than 100 feet per second. Using the above for example: Multiply the height by the object's acceleration due to gravity. If you know the terminal velocity of an object, divide that number by the square root of 2*g to determine the maximum height for which these equations will be valid for that object. Consequently, the velocity of the falling object in the example is 27.2 feet per second. The calculator uses the standard formula from Newtonian physics to figure out how long before the falling object goes splat: The force of gravity, g = 9.8 m/s 2 How you do this depends on what type of function you have. These concepts are described as follows: 1. However, if you’ve been given a position function (e.g. In order to find the velocity of a particular falling object, just multiply time (t) by gravity (t). If you’re given a position equation like h(t) or s(t), you’ll need to differentiate that function in order to find the velocity of the falling object. But we know that our velocity is going to be downwards here, because that is our convention. Tip: A negative sign indicates the height is decreasing. Calculates the free fall distance and velocity without air resistance from the free fall time. Example question: Find the velocity for the following position function:x(t) = 4t2 + 4t + 4, Step 1: In order to get from the displacement to the velocity, you will take the derivative of the displacement with respect to time. No further calculations are required here. Terminal Velocity Calculator. What is it’s velocity? This is linear motion. The function v(t) is the derivative of the position function. If an object is dropped from height h = m, then the velocity just before impact is v = m/s. Ascertain the height from which the object fell. This gives you an object’s rate of change of position with respect to a reference frame (for example, an origin or starting point), and is a function of time. If an object is traveling in a straight line (i.e. The program will read the height in meters (m) from which user dropped the object. The car traveled east a total of 118 feet. for the height), then you need a little calculus to derive the answer. On the other hand, if you have a jerk function you’re going to want to work backwards. Question: Hello, I Am Trying To Use Python To Calculate The Terminal Velocity Of An Object Falling From A Height Of 3 Meters. Step 2: Solve for the derivative. An object in free fall experiences an acceleration of -9.8 m/s/s. Georgia State University; Energy as a Tool for Mechanics in Problem Solving; R. Nave, Western Kentucky University; Falling Object Problems; David Neal; 2008. This is to say that the velocity of a free-falling object is changing by 9.8 m/s every second. The function enables you to find instantaneous change as well as average change. In order to find the velocity … The following formula is used to calculate an impact velocity. Tip: The velocity is not constant over time, so t makes an appearance. Velocity of a Falling Object Using Calculus, https://www.calculushowto.com/problem-solving/velocity-of-a-falling-object/. Multiply the height by 2, and divide the result by the object's acceleration due to gravity. Final Velocity of freely falling body from height h, when it reaches ground calculator uses Velocity on reaching ground=sqrt(2*Acceleration Due To Gravity*Height) to calculate the Velocity on reaching ground, The Final Velocity of freely falling body from height h, when it reaches ground is the speed just before touching the ground. v = Sqrt ( 2 * g * h ) Where v is the impact velocity (m/s) g is the acceleration due to gravity (9.8 m/s^2) h is the height of the object (m) Impact Velocity Definition The more, the heavier and more compact the falling object is. Determine the imperial solution by multiplying the time in free fall by 32 ft/s^2. Take the square root of the result to calculate the time it takes for the object to drop. If an object is merel… Calculate free fall velocity of an object Write a program that determines the speed or velocity of an object is traveling when it hits the ground. Hint:The given equation is not for the velocity of a falling object. When the projectile reaches the maximum height, it stops moving up and starts falling. Multiply the result by 2. If an object of mass m= kg is dropped from height h = m, then the velocity just before impact is The object undergo two kinds of forces they are, gravitational force and aerodynamic force. Copyright 2021 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. The average velocity that the car traveled was 14.75 feet-per-second eastward.

The simple and straightforward principles of Sudoku are one of its best features. Solving free Sudoku puzzle games can be a challenge sometimes. To play Sudoku for free, all one needs to do is be able to reason rationally and be familiar with the numbers from 1 to 9. The goal of this game is to complete the grid by using only the numbers from 1 to 9 without repeating any of them. The limitations the player must follow in order to fill the grid bring a lot of difficulties.
You’ve come to the right place if you want to play Sudoku more frequently but are not familiar with the rules. We examine the Sudoku rules that every beginner needs to be aware of in this article. Let’s get going!
Rule 1: Each Row Must Only Include One Instance of Each of the Numbers 1 Through 9.
The player must be very careful to avoid using any duplicate numbers when filling up any of the grid’s rows. The order of the digits doesn’t really matter.
Each free sudoku puzzle game begins with pre-assigned numbers on the grid, regardless of complexity. The player should use these numbers as clues to identify which digits are missing from each row and then insert them.
Rule 2: Each Column Can Only Include One Instance of Each of the Numbers 1 Through 9.
The same Sudoku rules apply to the columns and rows of the grid. The player also needs to fill in these with the numbers 1 through 9, making sure that each digit only appears once in each column.
The numbers assigned at the beginning of the puzzle act as clues for locating and recognizing the missing digits in each column.
Rule 3: The Digits May Only Appear Once in Each Block (nonet)
A typical 9 x 9 grid is made up of nine smaller 3×3 blocks, or nonets. Per nonet, the digits from 1 to 9 can only appear once.
This actually means that when the process of filling the rows and columns without duplicate digits moves forward, another restriction on the arrangement of the numbers is found inside each block.
Rule 4: Each Column, Row, and Nonet Must Sum Up to 45.
To check for duplicates or missing digits in each column, row, or block, the player can simply count the numbers or utilize their prowess in mathematics to add them all up. Each row, column, and group must add up to 45 (1+2+3+4+5+6+7+8+9=45).
Further Information to Put into Consideration
1. Every Puzzle has a Unique Solution.
Any given free Sudoku puzzle game has one solution, which is by correctly applying the Sudoku rules.
Only poorly designed puzzles or, more frequently, those where the player makes a mistake while solving and a duplicate is hidden somewhere else on the grid, are capable of having many solutions.
2. Guessing is Strictly Forbidden.
It is against the Sudoku rules to make an attempt to guess the solution for each cell. These mathematical puzzles need logic, not guesswork
The numbers supplied at the beginning of the game are the only hints needed to solve the grid.
3. Techniques and Notes
According to the Sudoku rules, noting the numbers that are potential candidates for each cell is both permitted and even encouraged. These help the player keep track of their progress and to think clearly and in an organized way.
Additionally, these notes become more crucial as the difficulty level of these puzzles increases so that you can apply the complex puzzle-solving techniques, such the X-Wing method or Swordfish approach, needed to finish the grid.
To sum up, Sudoku is a fantastic puzzle game for a reason. This game is a mind teaser and will leave your mind in terrific shape in addition to being entertaining and addictive to play. Additionally, Sudoku might enhance your ability to concentrate and use logic to solve it. These two crucial abilities will improve your life in many ways, whether at job or in your studies.
As was already mentioned, the best thing about free Sudoku puzzle game is how easy and uncomplicated its rules are. So long as you keep these rules in mind, you can complete your Sudoku puzzle fast and easily. Now that you are aware of the Sudoku rules, you may download it on your smartphone or table and demonstrate your Sudoku solving skills to relatives and peers.


New Delhi: Google Developer Emma Haruka Iwao spent Pi Day smashing the Guinness record for calculating Pi to the highest number of digits —31 trillion — breaking the previous record of 22 trillion. Iwao broke the record on March 14 by calculating the value of Pi, represented as 3/14 or 3.14 to 31.4 trillion decimal places. That's π x 10 to the power 13.
Denoted by the Greek letter π, Pi is defined as the ratio of a circle's circumference to its diameter. Pi's first three digits, 3.14, are known but the remaining is infinitely long. Calculating the rest of the digits that follow is difficult as the sequence follows no set pattern.
Iwao, a Google employee from Japan, used Google tool, Y-cruncher, a Pi-benchmark program created using a Google Compute Engine virtual machine cluster by Alexander J. Yee.
The calculation, which consumed 170TB of data, was completed in 121 days with 25 virtual machines. The new record is around 9 trillion digits more than the last world record set by Peter Trueb in November 2016. Iwao, who has worked at Google for the last three years, said she "feels very surprised."
She also became the third woman to set a world record for calculating pi.

A visually appealing arrangement or organization of 3 dimensional forms is known as a 3D- Composition. They can be created using simple geometric 3-D forms like cubes, spheres, cones, cylinders, cuboids or complex 3-D solids generated from basic forms.
Steps to create a 3-D Composition:
- Learn to draw 3-D objects preferably in Isometric view.
- Create an interesting arrangement of these objects considering
- Placement of the objects - smaller objects should be in front. The objects should be overlapping and preferably in two or maximum three layers. Avoid putting similar objects in the same area.
- Keep sufficient space around the composition as we may need to show the shadows of the objects.
- Show the effect of light by shading the object. Shading also helps to create the effect of three dimensionality of the objects.
- Show the cast shadows of the objects in the given light conditions.

On Thursday 2nd March 2017, year 5 dressed up for World Book Day.
We had a large range of different characters come to Cumwhinton School, a common character was 'Gansta Granny' written by David Walliams.
Our focus in Science has been materials. We tested which material would be best for a packaging material, by wrapping an egg in a chosen material and dropping it to see if it protected the egg from cracking.
We made this a fair test by using the same size egg and dropping the egg from the same height each time.
We have discovered that gravity is measured in Newtons. Did you know they are called newtons because the very first Scientist to think about gravity and ask the question Why? was called Isaac Newton!
We stood on a chair with a partner of different sizes and discovered that objects of different masses fall to the ground at the same speed because of gravity.
Another challenge we were given by Miss Collins was to build the tallest freestanding tower using only spaghetti and marshmallows.
This was difficult!

Have you heard the myth that girls are not good at math? Well, there’s a reason why it’s called a “myth”. It’s because it’s just not true. There can be no blanket statement that girls aren’t good at math, because math skills are influenced by genetics, culture, experience, upbringing and attitudes. There is not much
In a 2010 Change the Equation study, 30% of Americans polled said they would rather clean their bathrooms than do a math problem. Oh my gosh, seriously? There are a few things in life that are below cleaning my bathroom, but math certainly isn’t one of them. But then I’m one of the lucky ones
Boring. Repetitive. Pointless. Frustrating. Too easy. Too hard. These were a constant flow of phrases from the mouth of my 8-year-old daughter daily about math. As a homeschooling mom, I was the one enforcing this curriculum on her each day as we dove into our math lessons causing some math anxiety for both of us.
Did you know that you can pass your dislike of math down to your child? Studies show that a parent’s math anxiety can negatively impact their child’s future success in math. Researchers found that math-anxious parents who helped their children frequently with homework didn’t help much at all. Their children learned significantly less math during
For many, math is boring or seemingly irrelevant. It’s just numbers, formulas and word problems on paper. For others, math is intimidating because it can be abstract, complicated and full of bad memories. I’m certainly no mathematician as my C+ in high school calculus proves. And, I have felt all those feelings described above. Yet,

The program is intended for obtaining truth tables of logical functions with the number of variables from one to five. A logical (Boolean) function of n variables y = f(x1, x2, …, xn) is a function with all variables and the function itself can take only two values: 0 and 1.
The basic functions of logic
Variables that can take only two values 0 and 1 are called logical variables (or just variables). Note that a logical variable x can imply under number 0 some statement which is false, and under number 1 some statement which is true.
It follows from the definition of a logical function that a function of n variables is a mapping Bn to B, which can be defined directly by a table called the truth table of this function.
The basic functions of logic are functions of two variables z = f(x,y).
The number of these functions is 24 = 16. Let us renumber them and arrange them in the natural order.
Let us consider these functions in more detail. Two of them f0 = 0 and f15 = 1 are constants. The functions f3, f5, f10 and f12 are essentially functions of one variable.
The most important functions of two variables have special names and designations.
1) f1 – conjunction (AND function)
Note that the conjunction is actually the usual multiplication (of zeros and ones). This function is denoted by x&y;
2) f7 is a disjunction (or function). It is denoted by V.
3) f13 is implication (following). Denoted by ->.
This is a very important function, especially in logic. It can be viewed as follows: if x = 0 (i.e. x is “false”), then both “false” and “true” can be deduced from this fact (and this will be correct), if y = 1 (i.e. y is “true”), then truth is deduced from both “false” and “true”, and this is also correct. Only the conclusion “from truth is false” is incorrect. Note that any theorem always actually contains this logical function;
4) f6 – addition modulo 2. It is denoted by a “+” sign or a “+” sign in a circle.
5) f9 is equivalence or similarity. This f9 = 1 if and only if x = y. It is denoted by x ~ y.
6) f14 is Schaeffer’s dash. This function is sometimes called “not and” (since it is equal to the negation of the conjunction). It is denoted by x|y.
7) f8 is Pierce’s arrow (sometimes this function is called the Lukasiewicz stroke).
The remaining three functions, (f2 , f4, and f11) have no special designation.
Note that logic often considers functions from functions, i.e., superpositions of the above functions. In this case, the sequence of actions is indicated (as usual) by parentheses.

On International Pi day in 2011, I saw a video of a man playing notes that had been assigned to numbers 0-9, using the order of the digits of pi as the “score”.
In 2013, I circled back to this idea as a way to experiment with color palettes . Using the infinite numbers pi and phi as generators of painting sequence, I made a series of paintings. With each painting, I tweaked my code to determine what exact ratio of colors gave the feel of the source I was using for a palette reference. I tried out different formats. I did paint-offs to choose which infinite number yielded the most please flow of color. In the end pi won.


Below are four sample problems on two digit numbers involving calculations on the digits of the number.
If the digit in the ten's place of a two digit number is 3 less than the digit unit’s place and if the ratio of the sum of the digits of that number to that of the number is 1:4 then the number is:
a)32 b)34 c)36 d)38
Answer : c)36
Let the ten’s digit of the number be x.
Then the unit’s digit is x+3
Sum of the digits = x + x + 3 = 2x+3.
Then the number can be expressed as 10x +(x+3) = 11x + 3
The given ratio between the sum of digits to the sum = 1 / 4 = 2x+3 / 11x+3
4(2x + 3) = 11x + 3
3x = 9
x = 3
Then the required number is 11x + 3 = 11(3) + 3 = 36.
Hence the answer is 36.
The sum of the digits of a two digit number is equal to 9 and the number obtained by interchanging the digits of that number is 63 less than the number. Then the ten’s place of the two digit number is :
a)1 b)8 c)9 d)3
Answer : b)8
Let the ten’s place of the two digit number be x.
Since the sum of the digit is 9, the unit's place will be 9-x.
Then the number is represented by = 10x +(9-x) = 9x + 9
For the number with digits reversed, tens's place will be 9 - x and unit's place will be 9.
Therefore, the reversed digits number can be represented as 10(9-x)+x = 90 - 9x
Given that the new number is 63 less than the original number.
Therefore, New Number = Original Number - 63
i.e 90-9x = 9x + 9 - 63
18x = 144
x = 144/18
x = 8.
Then the number is 9(8) + 9 = 81.
Hence the required digit is 8.
If unit’s place of a two digit number is 2 more than the ten’s place and 144 is the product of the number and the sum of the digits of the number then the unit place of the number is:
a)4 b)1 c)5 d)3
Answer : a)4
Let the ten’s digit of the two digit number be x.
Then the unit’s digit is x + 2.
And the number = 10x + x + 2 = 11x + 2
The sum of the digits of the number = x + x + 2 = 2x + 2
Product of the number and sum of the digits = 144
i.e (11x + 2)(2x + 2) = 144
22x2 + 22x + 4x + 4 = 144
22x2 + 26x - 140 = 0
11x2 + 13x - 70 = 0
(x - 2)(11x + 35) = 0
x = 2 or x = -35/11
Since digit of a number cannot be a fraction, x has to be 2.
i.e., ten’s place of the number is 2.
And unit’s place = x + 2 = 4.
Hence the answer is 4.
If x and y are the numbers of ten’s and unit’s place of a two digit number(xy). If y is halved and x is doubled, the number obtained is equal to the number yx (i.e., interchange the digits of xy). Then the relation between x and y is:
a) x+y=2 b) x=2y c) y=2x d) x-y=2
Answer : c) y=2x.
Given that the ten’s and unit’s digit is x and y respectively.
Then the number = 10x + y.
The number obtained by interchanging the digits = 10y + x.
If y is halved (y/2) and x is doubled then the new number is 10(2x) + y/2
But the new number is equal to the number obtained by interchanging the digits.
Therefore, 10(2x) + y/2 = 10y+x
20x - x = 19y / 2
19x = 19y / 2
x = y/2
y = 2x
Hence the answer is option c.

A SIMPLE Introduction to Normal Deviations
A SIMPLE Introduction to Normal Deviations
You can find three basic sets of casino games: table games, video games machines, and randomly generated video games. Most table games, incorporating roulette, craps, baccarat, craps more, blackjack, etc., require several person to play. Some table games such as for example bridge, joker, etc., may be played by only one or two people. All other games are played by a team of competitors. The random variety game, also called slots, is probably the most popular casino games nowadays.
In the progressive slot machine game, as in other casino games like poker, blackjack, craps, etc., the object is to win real money from pay machines and obtain the corresponding payoff. Exactly the same type of progressive slot machine game are available in video slots. Some progressive slots in video casinos include their own distinct slot reels. When these distinct reels hit the pay-line, the correct quantity on the payoff reel pulls out and the appropriate amount on the device next pays out.
A lot of slot machines are available in most of the casinos. They’re categorized based on the winnings, maximum bet, reels used, locations and hrs of procedure. While playing a casino video game, there are a few types of slot machines that are popular among casino goers. These include regular machines, progressive devices and bonus/progressive machines.
As stated earlier, regular slots are available in the majority of the casinos. Slots in non-top quality casinos may use a random number generator. These machines can be purchased in various denominations, with regards to the casino’s minimum winning limit. They’re known by various names, included in this, regular, movie, combo, magnetic and spin equipment.
Progressive slots, because the name suggests, pay out a continuing amount regardless of how much the player has bet onto it. With the increase in house edge, the more a casino pays out, the larger the house edge is. With a more substantial house edge, a casino is said to get a “slot’s syndrome”, which is to state that the probability of a player winning 제왕카지노 on a progressive slot machine game is lower than in a normal machine.
Bonus offer and progressive casino gambling are also related because the latter make the gambler earn additional money in a shorter period of time. The casinos are able to maximize revenue through this. Put simply, the more the modern casino pays out, the more the player needs to win. On the other hand, in a casino, reward or progressive gambling house gambling means the same thing as good luck. This results in casino gamblers having a “feel good” factor and feeling positive about gambling.
The random number generator, which is a device found in casinos to assign probabilities, is also linked to the roulette wheel. Like the house edge, the probability of hitting a jackpot is definitely lower with the roulette wheel than in a machine. The random amount generator creates numbers which are independent of any acknowledged deterministic device. As such, a gambler can use this to his or her advantage. It makes the odds of hitting a bigger jackpot or number smaller compared to the actual probability on the roulette wheel and hence increases the chances of a gain.
Another factor that’s linked to the random number generator is the payout casino games. Although some of these casinos claim that they have their very own internal random generators, others simply just use a machine provided by the developer. Since they depend on the manufacturer’s guarantee of good quality, it isn’t surprising that the same email address details are again repeated again. This results in what is referred to as the diminishing returns.
An added factor that is linked to casino games available for roulette, craps, and slot machines is the stability of the payout. Roulette, craps, and slot machines are known to be the most popular type of games available for casinos. Their recognition is understandable given their ease of operation, which appeals to both gambling house owner and the gambler. The payout from these games is frequently the highest in every casino games available for people.
Common deviation, which is also known as mean-reverting mean, is used in standard deviation to calculate portfolio holdings of the gambler. Normal deviation can be used to measure how the portfolio holdings of the gambler modifications with time. Like the binomial model, the standard deviation gives rise to the casino principle “the standard deviation” (also called the beta distribution). Common deviation makes up about the beta distribution in regular casino games designed for roulette, craps, slots, along with other standard casino video games.
Apart from the profitability of the casino game titles, another factor affecting casino take up may be the casino house edge (house gain). The home edge is the difference between the expected winning number and the actual winning number at a internet casino. Standard deviations, in addition to the mean deviation, are widely used in casino management and games to ensure that casino games establishments have an optimal possibility of earning profits and minimizing prospective losses.

THINKING RETIREMENT – ANDY LANDIS – Let’s go back to school to study the math behind your Social Security. A little understanding of the numbers goes a long way to avoiding retirement surprises and shortfalls. Like other pension systems, your Social Security is based on three factors: eligibility, earnings and age. The Social Security Administration (SSA) puts its own twist on each factor.
Math 101: Compute your eligibility – To be eligible for Social Security retirement payments, you need 40 Work Credits (WCs). You can earn up to four WCs per year, so they’re sometimes called quarters. In 2015, you earn one WC for each $1,220 you earn anytime in the year. So if you earn four times $1,220, or $4,880 in 2015, you get all four WCs for the year. (Only work where you pay Social Security taxes counts. The cost per WC generally increases annually with inflation.) 40 WCs ÷ four WCs per year = 10 years of part-time work needed for a retirement payment. Click here to continue your lesson in retirement math.

The winners of the most prestigious prize in mathematics, the Fields Medal, were announced last week. The award, which recognizes up to four mathematicians under the age of 40 every four years, is recognition of both outstanding work and future promise.
Among the 2022 medalists, 37-year-old Marina Viazovska from Ukraine won for her groundbreaking work on how to pack 24-dimensional spheres.
In his honor, today’s first riddle is about how to wrap beers in three dimensions.
1. A checkout problem
Is it possible to put more than 40 cans of beer with a diameter of 1 unit and a height of 2.6 units in a box with dimensions 5 x 8 x 2.6?
James Maynard, 35, of the United Kingdom, won a 2022 Fields Medal for his numerous prime results. In tribute to its success, here is a puzzle around the number 13, a prime number.
2. Chairs, man.
Place 13 chairs along the walls of a rectangular room so that each wall has the same number of chairs as the wall it faces.
June Huh, 39, from the United States, won for her results linking graph theory, combinatorics, algebra and many other abstract concepts. A graph in this context means a network of discrete dots connected to each other, which is a way of thinking of a chessboard, which is made up of discrete squares connected to each other.
3. Chess Neighbors
Imagine a 9×9 chessboard. (Like a Sudoku grid, but with alternating black and white cells). Each square has a different person standing on it. Is it possible for all 81 people to walk to a neighboring square, so that each square again has a different person on it?
Hugo Duminil-Copin, 36, of French nationality, won a medal for his work on phase transitions in statistical physics. I couldn’t find a simple riddle on this area. If any readers can suggest one, please put it in the comments below.
I’ll be back at 5pm in the UK with the answers.
In the meantime NO SPOILERS!
Finally, if you like this column, you might want to buy the Guardian in newspaper form on Saturday, July 16. I have edited a 16 page summer puzzle supplement which will be free with the paper. It features puzzles from around the world, including hand-crafted sudoku by our friends at Cracking the Cryptic, all-new Japanese logic grid puzzles, a selection of Grabarchuk family teasers, many types of word puzzles and several crosswords, including a guide of how to solve the puzzles.

Hard math sat questions. Brief Overview of the ACT Math Section
Tonya hits a golf ball from an initial height of 10 American wire rope association. Want to improve your SAT score by points? For starters, you can tell Hard math sat questions the graph that the y-intercept is 2, which automatically eliminates "C" where the y-intercept is B The matth height of the students in Juan's English class is 2. This question is tricky because it gives you lots of numbers and letters and it's not entirely clear what you're supposed to do with them. Ask below and we'll reply!

The SAT doesn't just test how good you are at mathreading, and writing — it tests how good you are at taking the SAT. Preparing for the math section of the test Hard math sat questions lots of practice and memorization of some formulas, but it's also important to know how to recognize trick questionssift through unnecessary details, and remember simple tricks like reading the entire question through before starting to work on it.
Here are 15 math problems from the SAT that people usually get wrong — with step-by-step explanations for how to solve them. But look carefully, — it's asking for the original price of the computer. So if p is the total amount Alma paid to the cashier and x is the original price of the laptop, the equation reads as follows:. You're trying to figure out the price per pound of beef b when it was equal to the price per pound of chicken c.
So you need to find the value of x in order to plug it back into the "b" equationwrites Dora Seigel of PrepScholar. That leaves you with 0. Now that you know the value of x, you can put it into the equation for the price of beef:. This question is tricky because it gives you lots of numbers and letters and it's Wife swap cum gangbang entirely clear what you're supposed to do with them.
Bleach contact time crucial to figure out what the question is asking before you start doing pointless calculations that won't get you any closer to the answer.
PrepScholar suggests reading the entire question through, circling the important information, and determining what you're being asked before doing any work. Start with what you know: triangle ABC is a right triangle, and angle B is the right angle. That means that AC is the hypotenuse and Bed diaper in teen wetting is one of the sides.
You can use the Pythagorean theorum to figure out the length of the last remaining side:. Caroline C. The question is asking for the absolute value of x, not the actual value of x. You want the absolute value of x - 3 to be between six and seven, so multiple values of x work: But the answer you Hardcore seduction write is the absolute value of those numbers: 3. According to PrepScholar, eight and two are both powers of twoso you can simplify things before you begin:.
Because the numerator and denominator of the fraction are now the same, you can rewrite the equation as 2 3x-y. And how convenient! A big chart can scare off test-takers who think it will take too long and they'll return to it later if they have time. But PrepScholar says it's just like any other math question. For starters, you can tell from the graph that the y-intercept is 2, which automatically eliminates "C" where the y-intercept is Otherwise, the graph would be shifted to the left or right.
As PrepScholar explainsit's impossible to answer this question if you don't know the formulas for the sine and cosine of an angle. You can still solve this problem by drawing a diagram of the trianglebut speed is key on the math portion of the SAT, where you should allot yourself one minute per question. Here, the problem tells you that sides AB and AO of a triangle are equal.
AO is a Adult gay mpegs statement of the circle, and so is BO. The radii of Hard math sat questions circle are always equal, so AO and BO are also the same length.
That means that triangle ABO is an equilateral triangle, and all of its angles measure 60 degrees. Speed is key on the SAT, and the quickest way to solve this problem is to imagine that RS is the diameter of a complete circlesays Prepscholar. You can do this because the picture shows two radii and two half-circles — Pony mom them together and you have one circle.
PrepScholar recommends plugging in real numbers to a theoretical math question to figure out the correct answer. This equation is cleverly disguised as a word problem. Don't forget the last step! The question isn't asking for the value of x, it's asking for 2x.
Ben made three times as many as Ali, and Carla made twice as many as Ben. Put Carla's sandwiches in terms of Ali's sandwiches so that you can combine like terms. Talia Lakritz. Snapchat icon A ghost. Many people misread this question about the original price of a laptop. This question requires you to write out all the steps, even though the math itself isn't too complicated. Here, people often solve the wrong part of the equation — a common mistake. This question about absolute values is easy to slip up on if you miss one little detail.
Sometimes, it's simply the format of a question that throws people off. Pictures often confuse people. Quadratic functions sneak up on many people who take Daniel tracy morris new york SAT. Some people forget to memorize formulas that aren't provided.
If the problem involves a circle, the key is likely understanding the radius. Don't let drawings fool you — this is a question about circles, not squiggles. You can figure out theoretical math questions with real numbers.
For single variable equations, isolate the variable and make sure you know what the question is asking. You don't need multiple variables to solve this question about sandwiches. Keep everything in like terms for maximum efficiency.

This paper develops importance resampling into a variance reduction technique for Monte Carlo integration. Importance resampling is a sample generation technique that can be used to generate more equally weighted sam- ples for importance sampling. This can lead to significant variance reduction over standard importance sampling for common rendering problems. We show how to select the importance resampling parameters for near optimal variance reduction. We demonstrate the robustness of this technique on common global illumination problems and achieve a 10%-70% variance reduction over standard importance sampling for direct lighting. We conclude that further variance reduction could be achieved with cheaper sampling methods.
