Use the graph of a survey of 70 zoo visitors were asked to name their faviorate animal exhibit.
bears. 6
elephants. 17
monkeys. 21
penguins. 13
snakes. 13

a. suppose 540 people visit the zoo. predict how many people will choose the monkey exhibit as their faviorate.

b. suppose 720 people visit. predict how many people will choose the penguin exhibit as their faviorate.

What are the solutions of the system? y = x^2 + 2x +3y = 4x - 2a. (-1, -6) and (-3, -14)b. (-1, 10) and (3, -6)c. no solutiond. (-1, -6) and (3, 10)

In which direction does the left side of the graph of this function point? f(x) = 3x3 - x2 + 4x - 2

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?
