Let X be a random variable with support {1, 2, 3, 5, 15, 25, 50}, each point of which has the same probability 1/7. Argue that c = 5 is the value that minimizes h(c) = E( |X − c| ). Compare c with the value of b that minimizes g(b) = E[(X − b)2].

Solving equation 13-715x=130x we get $x= \frac{1}{65}$

Step-by-step explanation:

We need to solve the equation 13-715x=130x

Combining like terms and solving

$13-715x=130x\\Adding \ 715x \ on \ both \ sides:\\13-715x+715x=130x+715x\\13=845x\\Divide \ both \ sides \ by \ 845\\\frac{13}{845}=\frac{845x}{845}\\=x= \frac{1}{65}$

So, solving equation 13-715x=130x we get $x= \frac{1}{65}$
