Question

the mean of 4,8,9,x,2 is 6. calculate the value of x

Answer 1

Answer:

7

Step-by-step explanation:

the mean is (the sum of numbers in a data set)/(# of points in that data set).

So,

$\frac{4+8+9+x+2}{5} = 6$,

$\frac{23+x}{5} = 6$,

23+x = 6*5

23+x = 30

x= 30-23

x = 7

Hence, the value of x is 7.
