Question

Solve the following question. *

Answer 1

The mean of x and y is equal to t.

Explanation:

Given that,

The mean of t and t+2 is x.

The mean of t and t-2 is y.

i.e.

`x=(t+t+2)/(2)\\\\x=(t+1)`

and

`y=(t+t-2)/(2)\\\\x=(t-1)`

The mean of x and y is :

`M=(x+y)/(2)\\\\M=((t+1)+(t-1))/(2)\\\\M=(2t)/(2)\\\\M=t`

Hence, the mean of x and y is equal to t.
