1) Richard is asked to transform the graph of b(x) below. b(x)
The graph of b(x) is transformed using the equation g(x)=(x-3)+21
Describe how the graph of b(x) changed to form the graph of g(x),

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
