Answer:

Step-by-step explanation:

The coefficient of variation CV is given by the following formula:

$CV = \frac{\sigma}{\mu}$

In which $\sigma$ is the standard deviation and $\mu$ is the mean.

Bob's weight has a mean of 200 pounds with a standard deviation of 16 pounds

This means that $\sigma = 16, \mu = 200$ .

So his coefficient of variation is

$CV = \frac{16}{200} = 0.08$

Mary's weight has a mean of 125 pounds with a standard deviation of 10 pounds.

This means that $\sigma = 10, \mu = 125$

So her coefficient of variation is

$CV = \frac{10}{125} = 0.08$

They have the same coefficient of variation, so the correct answer is.

RoseWind [281]

Answer:

You add 5 each time so we just need to multiple 5 by 40 since we alredy have the first three terms.

40*5=200

21+200=221

Hope This Helps!!!
