Given the equation y=mx+b, what will happen to the corresponding linear graph when the value of b is changed? a. the line will become flatter b. the line will become stepper c. the line will shift up or down d. this cannot be determined from the information given

What is the sum of these mixed numbers 2 1/8 + 4 3/8

State one method by which you can recognize a perfect square trinomial.

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?
