This means the mean of the distribution of is either 45 + 12 = 57 or 45–12 = 33, because for data value x = 45 deviation is 12.

in second case

This means the mean of the distribution of is either 84 + 12 = 96 or 84–12 = 72, because for data value x = 84 deviation is 12.

It means the mean of the distribution of is either 84 - 20 = 64 or 84 + 20 = 104 , because for data value x = 84 deviation is -20.

HI!,

Let f(x)=cosx

Prove f^(x)=sinx by definition

and...

Let f(x)=x^n

Prove f^1(x)=nx^n-1  by definition
