Solve the quadratic equation by using a graphic approach. Round your answer to the hundredths place. x squared minus 2 x minus 4 = 0 a. x = 3.24 or x = -1.24 c. x = 4.24 or x = -0.24 b. x = 2.73 or x = -0.73 d. x = 5.24or x = -1.24

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

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
