Question

Each week your science teacher gives a fifteen-point quiz. Your current scores are shown in the table. What is your mean quiz score?

Answer 1

Answer:

12.

Step-by-step explanation:

To find the mean of a group of data, you add up all of the numbers and divide the total by the amount of numbers there are. In this case, you have 15,11,10,11,14,10,15,10,and 12.

All of those numbers added together is 108.

108 divided by 9 numbers, or weeks, is 12.

The average, or mean, is 12.

Answer 2

Answer:

12

Step-by-step explanation:

To get the mean score , sum the scores and divide the result by the number of scores

That’s

15 + 11 + 10 + 11 + 14 + 10 + 15 + 10 + 12 = 108

Therefore

108/9 = 12

The quiz mean score is 12
