Find the mean number of hours for these students.
If necessary, round your answer to the nearest tenth.

Answer 1

To find mean, add all of them together then divide by number of terms.

15+6+20+17+7+17+10= 92
92/7≈13.1

hope it helps!!

Answer 2

What is the mean of numbers?

The mean value is the average of the numbers given to you. To find the mean, add the numbers up and divide by how many there are.

Let's address your question. You have been asked to find the mean of

15, 6, 20, 17, 7, 17, 10

First, add the values to each other:

15 + 6 + 20 + 17 + 7 + 17 + 10 = 92

Now, divide by the amount of numbers there are. There are 7 numbers, so:

92 ÷ 7 = 13.14285714

Round the number to the nearest tenth, and you have a mean value of 13.1
