(a) find parametric equations for the line that passes through the point (−2, 5) and is parallel to the vector < 3, −8> . (enter your answer as a comma-separated list of equations where x and y are in terms of the parameter t.)

The parametric equations for the line are:

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
