To find out the average score, all we need to do is to add all the scores and then divide the result by the amount of numbers we added. So in this situation it'll look like this:

(10.2 + 11.4 + 10.5 + 12.6 + 12.2 + 11.6 + 13.1 + 12.8) ÷ 8 =
= 94.4 ÷ 8 =
= 11.8

Answer: Marvin's average score was 11.8.

Answer:

The average score is:

                           11.8

Step-by-step explanation:

We know that the average score is the ratio of the sum of all the scores to the total number of scores.

Here the total number of scores are: 8

Also, the sum of all the scores are:

10.2+11.4+10.5+12.6+12.2+11.6+13.1+12.8=94.4

Hence, the average score is:

[tex]Average\ score=\dfrac{94.4}{8}\\\\Average\ score=11.8[/tex]
