A company that manufactures memory chips for digital cameras uses the formula 31ñ (407n +9n) to determine the cost, c, in dollars, for producing n chips. This formula
can be written as c = 120/na + 27 Vn, where a and b are constants.
What are the values of a and b?
A. a = 2 and b = 3
B. a = 3 and b = 2
C. a = 4 and b = 6
D. a = 6 and b = 4

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?
