The mean of sample x is 5.83

The standard deviation is 5.63

<h3>What is standard deviation?</h3>

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Given:

Frequency:  2 2 4 13 13 1

If x is the pair of sneakers owned of the frequency,

mean = 2+2+4+13+13+1/5

= 35/6

= 5.83

The  standard deviation is equal to 5.63.

Ryan $65 for n books. Write an expression that can be used to find the cost of one book.
eimsori [14]

Answer:

x=65/n where x is 1 book and n the number of books

Step-by-step explanation:

If n is the number of books, lets say 1 book is "x", then

nx=65

x=65/n

for example

n=1    then x=65

n=2 then x=65/2

n=3 then x=65/3
