Answer 1

So to find the mean of the grades you would add them all up then divide by the number of number like below:
87+95+88+92+90+73+98= 623
623/7=89
So your answer would be C.89


I hope this helps!!!!!!!

Answer 2

Hi there!

This is simply just adding up all the numbers and dividing it by the number of values there are.

So 87+95+88+92+90+73+98= 623
There are 7 values so
623/7= 89
The average of the values is 89.

Hope this helps!
