Question

If
the mean of 16, 14 ,x, 23, 20 is 8
Find
the value of x​

Answer 1

Answer:

mean =16 + 14 + x + 23 +20

5

8= 16 +14+23+20+x

5

8×5= 16+14+23+20+x

40= 73+x

40-73= x

-33=x

hence value of x is -33

Answer 2

Answer:

Given  

Mean = 8

Observations =16, 14, x, 23 ,20

No. of observations = 5  

Mean= sum of observation

            No. of observation

 8      = 16 + 14+x+23+20

                       5

8     =73 + x    ⇒ 73 + x = 8 * 5

              5

   73 + x = 40

      x = 40 - 73

     x = -33

The value of x = -33
