Answer 1

First you add all the numbers together. So you add 82+93+75+89 to get 339. Once you get that, you divide it by the amount of numbers there are. In this case, it's 4. 339 divided by 4 is 84.75.

Answer 2

The average of the John scores is 84.75.

Explanation:

Formula of average is given as :

`A=\frac{\text{Sum of all the terms}}{\text{Number of terms}}`

We have:

Test grades of John: 82, 93, 75, and 89

Number of terms - 4

Average of the score of the John;

`a=(82 + 93 +75 + 89)/(4)=84.75`

The average of the John scores is 84.75.
