Question

The median of the following observations in ascending order. 8, 9, 12, 18, (x+2), (x+4), 30, 21, 34, 39 is 24. Find x. (GET 45 PTS)

Answer 1

Hey !

I would be glad answering that !

Here, we observe that 'n' is even.

So, the formula (n/2)th + (n/2 + 1)th/2 will be used.

So it will be 5th + 6th/2 = 24
which is 2x + 6/2 =24
2x + 6=48
2x = 42
x = 21

Hope I helped you !

Answer 2

the formula (n/2)th + (n/2 + 1)th/2 will be used.

So it will be 5th + 6th/2 = 24
which is 2x + 6/2 =24
2x + 6=48
2x = 42
x = 21
