Question

1. If the median of 12, 13, 16, x+2, x+4, 28, 30, 32 is 23 then find the value of “x”?

Answer 1

Answer:

value of “x” is 20

Step-by-step explanation:

Data points : 12, 13, 16, x+2, x+4, 28, 30, 32

n = 8 (even)

Median is average of 8/2th data point and 10/2th data point

8/2th data point is x+2

10/2th data point is x+4

Median = (x+2+x+4) / 2

 23       = (2x +  6)/2

 46     = 2x  + 6

 2x    =  40

    x = 20
