Sara got 88, 90, 75, 78, 100, 54, 90, 100, 45, and 60 on her English tests

What is the mean of Sarah's English tests

Answer: 78

Step-by-step explanation:

88+90+75+78+100+54+90+100+45+60 = 780

Divide this number by the total number of factors, in this case 10:

780/10 = 78

The answer is 78 because when you add all the numbers it equals 780 and you need to divide the end sum by the amount of numbers added to get it. So in the end there were 10 numbers added to equal 780 so 780/10 equals 78
