Below are the jersey numbers of 11 players randomly selected from a football team. Find the range, variance, and standard deviat

Aleksandr-060686 [28]

Answer:

Range = 71

Variance = 546.0

Standard Deviation = 23.4

Option A) Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless.

Step-by-step explanation:

We are given the following data set in the question:

33, 29, 97, 56, 26, 78, 83, 74, 65, 47, 58

Formula:

$\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}}$

$\text{Variance} = \displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}$

where $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{646}{11} = 58.7$

Sum of squares of differences = 5460.18

$\text{Variance} = \frac{5460.18}{11} = 546.0$

$S.D = \sqrt{\frac{5460.18}{10}} = 23.4$

Sorted Data Set: 26, 29, 33, 47, 56, 58, 65, 74, 78, 83, 97

Range = Maximum - Minimum

Range = 97 - 26 = 71

Based on the values, we can say that

Option A) Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless.

Point m is the midpoint of line segment ab, b is at (20,4), m is at (18, -2) and a is at (p,q). what is p+q?

Alexandra [31]

The x-value of a midpoint is the average of the x-values of the ends.
The y-value of a midpoint is the average of the y-values of the ends.

The x-value of the end at b is 20 and it's 18 at the middle.
x has decreased by 2 in the course of 1/2 of the line.
So it will decrease another 2 during the other half of the line.
The x-value at the other end, at a, then, is 16.

The y-value of the end at b is 4 and it's -2 at the middle.
y has decreased by 6 in the course of 1/2 of the line.
So it will decrease another 6 during the other half of the line.
The y-value at the other end, at a, then, is -8.

The other end of the line, at a, is at (16, -8) .

The sum of the coordinates at a (p+q) is 8 .

LMNP is rotated 180 degrees clockwise around the origin. What are the coordinates of L?

Alona [7]

$\huge\boxed{L^\prime(0, -1)}$

To rotate a point around the origin by 180 degrees, multiply both parts of the coordinate point by $-1$ . (This means you go from $(x, y)$ to $(-x, -y)$ .)

$L(0, 1)$

$L^\prime(0*(-1), 1*(-1))\\\boxed{L^\prime(0, -1)}$
