b The following numbers are written in descending order of their values:
-8, 60, 52, X-3, X-8, X-11, 30, 25, 22 and 20.1f their median is 39, find the value
fx and hence find the mean of the given observations.

Answer 1

Step-by-step explanation:

x=n/2(n=total numbers in question)

x=10/2

x=5

:.x-3=5-3=2

x-8=5-8=-3

x-11=5-11=-6

mean = -8+60+52+2-3-6+30+25+22+20/10

mean = 90/10

mean = 9

thats it
