An office supply store carries several types of all-in-one printers. For one particular model, the business managers are trying to determine
what price will result in the best sales of the printer. The graphs of revenue, cost, and profit for this model, based on price, are shown
Using the graph, which price should result in the maximum profit for the sales of this printer?

Can you me find the slope! (30 points)

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?
