Question

Find the value of x such that the data set has a mean of 107.

100,123,106,115,108,X
X=

Answer 1

Take 107 and multiply it by 6, this gives you what you want to end up with.

Then add all the numbers you are given together.

Next take the above answer, plus x, set it equal to what 107*6 equals then solve

100+123+106+115+108+x=107(6)
552+x=642
552-552+x=642-552
x=90

Answer 2

the answer would be 90
