Question

The mean of 6 observations is x,x+3,x+6,x+9,x+12,x+15 is 8

Answer 1

ANSWER:

1/2;7/2;13/2;19/2;25/2;31/3

EXPLANATION:

Given:

mean of the data=8

We know that , mean of the data=sum of observations÷ Number of observations

sum of observations=X+X+3+X+6+X+9+X

+12+X+15=6x+45

Number of observations=6

As per the problem, 6x+45/6=8

6x+45=48

6x=48-45

X=3/6=1/2

Therefore , the 6 observations are 1/2;7/2; 13/2;

19/2;25/2;31/2
