Giving 98 points! what is the effect on the graph of the function f(x) = x when f(x) is replaced with −1/2f(x) a) vertical reflection over x-axis and vertical stretch b) vertical reflection over x-axis and vertical compression c) horizontal reflection over y-axis and horizontal stretch d) horizontal reflection over y-axis and horizontal compression

Ill mark the brainliest if you me with the these three questions 7,8,9

Aadc is formed by reflecting aabc across line segment ac, as shown in the figure. if the length of ac is 4 units, the area of aadc is square units.

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?
