Responses
A 80
B 50
C 55
D 20
E 60
To find the mean of a set of numbers, you add up all the numbers and then divide the sum by the total number of values. Therefore, the mean of the given set of numbers {20, 30, 40, 50, 60, 70, 80} is:
(20 + 30 + 40 + 50 + 60 + 70 + 80) / 7 = 350 / 7 = 50
Therefore, the correct answer is B, 50.
