A student earned the scores in the data set in one course. {90, 87, 58, 79, 91} What is the mean of the scores?

Answer 1

mean of the scores: 81

Step-by-step explanation: Mean means the average

Mean = (sum of #s) / amount of #s

sum of numbers = 90 + 87 + 58 + 79 +91 = 405

amount of #s = 5

405/5 = 81

First, add all the numbers together:

90 + 87 + 58 + 79 + 91

= 405

405 ÷ 5

= 81
