Answer:

And if we have a binomial times a binomial we'll have four products or we can think of this as double distribution. We distribute the a so we'd have a times C plus a times D.

An ice skater is spinning about a vertical axis with arms fully extended. If the arms are pulled in closer to the body, in which

12345 [234]

It should be noted that the angular momentum remain constant and kinetic energy of the skater increases.

<h3>What is Angular momentum?</h3>

Angular momentum can be regarded as the property of any rotating object given by moment of inertia times angular velocity, since No net torque is done on the object, then angular momentum is constant.

Kinetic Energy which is also the energy of motion in the Ice skater will increase since their is a pull.

Consider a sample with data values of 27, 25, 20, 15, 30, 34, 28, and 25. Compute the 20th, 25th,65th , and 75th percentiles

Kay [80]

Answer:

Percentile of 20th = 20

Percentile of 25th = 22.5

Percentile of 65th = 28

Percentile of 75th = 29

Explanation:

Sort the numbers in ascending order:

15,20,25,25,27,28,30,34

i = P/100 * N ( i index is the position of the number. Index 1 = 15, index 2 = 20, and so on)

Index of the 20th percentile:

20/100 * 8 = 1.6

Round 1.6 to the next integer = 2

The second number I=20

The 20th percentile is 20

Index of the 25th percentile:

25/100 * 8 = 2

Because 2 is an integer the percentile of 25th is the average of I=20 and I=25

(20+25)/2=22.5

The 25th percentile is 22.5

Index of the 65th percentile

i = 65/100 * 8 = 26.5 = 5.2

Round to the next integer = 6

The 65th percentile is 28

Index of the 75th percentile

I = 75/100 * 8 = 6

Since 6 is an integer (28+30)/2 = 29 percentile
