Hey! solve these problems, a statement and reason format would be nice too. in advance for your i really appreciate it.
the typed out questions for 8 and 11 are : (if you can't read my handwriting)
8. the lengths of the shorter altitude and the shorter side of parallelogram are 9 cm and √82 (square root of 82) cm, respectively. the length of a longer diagonal is 25 cm and the length of an altitude is 15 cm. find the area of the trapezoid.
11. the perpendicular bisectors of sides ac and bc of triangle abc intersect side ab at points p and q, respectively, and intersect each other at point e in the exterior of triangle abc. find the measure of angle acb if measure of angle cpq=78° and measure of cqp is 62°.

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?
