Answer 1

Answer:

7.58 miles per week

Step-by-step explanation:

This is a mean question...

by mean I mean mean, like mean, median, mode, range. Wow that was confusing, let me start. ;)

To solve for mean, just add all numbers in the data set together, and then divide by the amount of numbers in the set.

5.5 + 7.25 + 10 = 22.75

22.75/3 = 7.58333333333

Round that to the hundredths and you get: 7.58 miles per week

If you liked my answer brainliest is always appreciated ;)

Answer 2

$\text{We need to find the average amount of miles she ran per week}\\\\\text{We know that she ran 5.5 miles the first week, 7.25 miles the second}\\\text{week, and 10 miles the third week}\\\\\text{To find the average, add all of the miles and divide by 3}\\\\5.5+7.25+10=22.75\\\\22.75\div3=7.5833333333\\\\\text{Round to the nearest hundredths place}\\\\\boxed{\text{7.58 miles}}$
