Question

b) The median of 6. X + 6. 2x + 6. 24 is 9. Find x. Also, find
their mean.​

Answer 1

Answer:

6.x+6.2x+6.24 = 6x+12x + 134

median = (n+1)/2=(3+1)/2 4th term = 12x

A.T.Q 12x=9 or x = 3/4

6x = 6*3/4 = 9/2 = 4.5

12x = 12*3/4 = 9

data = 4.5 + 9 + 134

mean =(4.5 + 9 + 134)/3 = 147.5/3 = 49.1666667

hence x = 3/4 and mean = 49.16666667
