the number of points in the first five games of the football season are listed below. what is the mean number of points scored?

yarga [219]

^ You again? Quit being sus and answer the question here instead of elsewhere.

To find the mean, all you have to do is add each number and then divide by how many numbers you added.

So, 38 + 29 + 16 + 42 + 33 = 158. There were five numbers added, so the next step is to divide 158 by 5. That equals 31.6 as your answer.
