Question

The mean for the set of numbers 12 10 7 8 m is 25 what is the value of m

Answer 1

m = 88

Explanation:

The mean of a set of data is calculated using the formula

mean =
`(sumofdata)/(count)`

hence

`(12+10+7+8+m)/(5)` = 25 ( multiply both sides by 5 )

37 + m = 125 ( subtract 37 from both sides )

m = 88
