During the eclipse on january 26, 2009, the moon's shadow traveled 14,500 kilometers and covered 0.9 percent of the surface area of earth. earth's surface area is about 512 million square kilometers. suppose the area covered by the shadow was rectangular. what would be the width of such a rectangle? round your answer to the nearest kilometer. a: 318km b: 350km c: 3178km d: 392km

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)

Which graph represents the function g(x) = |x + 4| + 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?
