Question

Mia’s goal was an average of 97 on her four tests. She scored a 94, 98, 99, and 97. Did she meet her goal?

Answer 1

• Average/Mean Formula:
  `\frac{\textsf{sum of all numbers in the data set}}{\textsf{how many numbers there are in the data set}}`

To find out if she met her goal, add the test scores and then divide by 4:

`(94+98+99+97)/(4)=(388)/(4)=97`

Since the average of her test scores is 97, she had met her goal.
