Ans - Parity.
Parity is a mathematical term that describes the property of an integer's inclusion in one of two categories: even or odd. An integer is even if it is 'evenly divisible' by two (the old-fashioned term "evenly divisible" is now almost always shortened to "divisible") and odd if it is not even.[1] For example, 6 is even because there is no remainder when dividing it by 2. By contrast, 3, 5, 7, 21 leave a remainder of 1 when divided by 2. Examples of even numbers include −4, 0, 8, and 1738. In particular, zero is an even number.[2] Some examples of odd numbers are −5, 3, 9, and 73. Parity does not apply to non-integer numbers.
A formal definition of an even number is that it is an integer of the form n = 2k, where k is an integer;[3] it can then be shown that an odd number is an integer of the form n = 2k + 1. This classification applies only to integers, i.e., non-integers like 1/2, 4.201, or infinity are neither even nor odd.
The mean is 6 and the standard deviation is 6
s = 4 h * 6 km/h = 24 km
v = 2 * 24 km / (3 h + 4 h) = 6.857 km/h
Fluffy is 9 9/16 lbs
Whiskers is 9 7/8 lbs
Mr. Nibbles is 9.75 lbs
Let’s first convert the fraction 7/8 to compliment the fraction 9/16:
7/8 = 14/16
9 7/8 is now 9 14/16, which is heavier than Fluffy’s weight.
Now that we know that, let’s convert .75 into a fraction:
.75 = 3/4
Make 3/4 compliment the other fractions:
3/4= 12/16
Let’s look at the weights now:
Fluffy: 9 9/16 lbs
Whiskers: 9 14/16 lbs
Mr. Nibbles: 9 12/16 lbs
Having a common denominator for all fractions makes it easier to determine how big or small the numbers are.
So, the order from heaviest to least heavy is:
Whiskers, Mr. Nibbles, Fluffy
