Heloise considered two types of printers for her office. each printer needs some time to warm up before it starts
printing at a constant rate.
the first printer takes 30 seconds to warm up, and then it prints 1 page per second.
the printing duration (in seconds) of the second printer as a function of the number of pages is given by the
following table of values:
16
pages duration (seconds)
40
32 60
48
80
which printer takes more time to warm up?

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?
