The main cable of a suspension bridge is modeled by the equation y=0.0048(x - 50)2 + 6. At what
horizontal distances from the left support is the
cable 10 ft above the roadway?
y = height in feet of cable above the roadway
Choose the equation one must solve to answer the
question
O 0 = 0.0048(x - 50)2 + 6
10 =0.0048(x - 50)2 + 6
O y=0.0048(10 - 50)2 +6
DONE
x = horizontal distance in feet from left support

Combine the information in the problem and the chart using the average balance method to solve the problem.

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?
