Answer 2

The value of E(2x - 9) = 1

Given :

The mean of a distribution is 5

To find :

The value of E(2x - 9)

Formula :

E(ax + b) = aE(x) + b

Solution :

Step 1 of 2 :

Write down the given data

Here it is given that mean of a distribution is 5

∴ E(x) = 5

Step 2 of 2 :

Find the value of E(2x - 9)

$\displaystyle \sf{E(2x - 9) }$

$\displaystyle \sf{ = E(2x ) - E(9) }$

$\displaystyle \sf{ = 2E(x ) - 9 }$

$\displaystyle \sf{ = (2 \times 5) - 9 }$

$\displaystyle \sf{ = 10 - 9 }$

$\displaystyle \sf{ = 1}$
