5 positive integers are arranged in ascending order, as follows:
7, 8, 11, 11, X
The median and the range are equal.
Find 2.

Respuesta :

Answer:

X = 18.

Step-by-step explanation:

The median = 11 so the mean is also 11 (given).

So mean  = 11 = (7 + 8 + 11 + 11 + X) / 5

(37 + x)/ 5 = 11

x + 37 = 55

x = 55 - 37 = 18.
