Question

101​, 121​, 104​, 114​, 110​, ​x, mean 106
What is X?

Answer 1

x = 86

Explanation:

The mean is calculated by summing the data set and dividing by the count.

`(101+121+104+114+110+x)/(6)` = 106

Multiply both sides by 6

550 + x = 636 ( subtract 550 from both sides )

x = 86

Answer 2

If the mean is 106 and the mean is all of the numbers added and divided by the amount of numbers, 106 * 6 = 636 which is the amount of each number added together. Subtract each of the known numbers from 636 to get the remaining, x. The answer is x = 86
