Question

What is the mean (rounded to the nearest hundredth) of

90.75
99.17
71.80
100.00
97.33
79.58
92.58
87.09
81.59
91.86
and 94.18

Answer 1

To find the mean, you need to add up all the numbers and then divide by the total number of numbers.

90.75 + 99.17 + 71.80 + 100.00 + 97.33 + 79.58 + 92.58 + 87.09 + 81.59 + 91.86 + 94.18 = 985.93

There are 11 numbers, so we divide the sum by 11:

985.93 ÷ 11 = 89.63

Rounded to the nearest hundredth, the mean is 89.63.

Answer 2

To find the mean of the given numbers, we need to add them up and divide by the total number of numbers.

90.75 + 99.17 + 71.80 + 100.00 + 97.33 + 79.58 + 92.58 + 87.09 + 81.59 + 91.86 + 94.18 = 985.93

There are 11 numbers in the list, so we divide the sum by 11:

985.93 ÷ 11 ≈ 89.63

Therefore, the mean (rounded to the nearest hundredth) of the given numbers is 89.63.
