Question 8 Multiple Choice Worth 4 points) (04.02 MC)
Randolph is creating rectangle WXYZ so that WX has an equation of y = -x + 4. Segment XY must pass through the point (-2, 6). Which of the following is the equation for XY?
Oy-6= 1(x- (-2)
Oy-(-2) = 36-6)
Oy - 6 = -4x-(-2))
Oy - (-2) = -4(x - 6)

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event a↵ect the mean and standard deviation of the wait time until success?
