Find the value of x2 - 5x + 9 when x = 6.
The value of the expression when x = 6 is

X²-5x+9

=>6²-5×6+9

=>36-30+9

=>6+9

=>15

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

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
