Question

The mean of 3, 7, 8, 10, and X is 8
FInd the value of x

Answer 1

Answer:

(6+8+10+x+7) divided by 5 = 8

Therefore 31+x = 40 by cross multiplication

Hence on solving, x = 9

Answer 2

Answer:

12

Step-by-step explanation:

mean =sum of all observations/number of observations

mean=8

observations=3,7,8,10andx

(3+7+8+10+x)/5=8

(28+x)=8*5

28+x=40

x=40-28

x=12

value of x is 12
