given the mean of 4, 7, x, 9 and 8 is 16, find the value of x

OpenStudy (anonymous):

to find the mean, you add everything together and divide by the number of terms you added. so... you would add everything together and divide by 5 to get 16... so the sum of all of the numbers and x would have to = 16*5, which is 80... so subtract the sum of all of the numbers from 80 to get x
