An engineer lives 21 miles east and 22 miles north of a water tower. A bridge she is building is located 12 miles west and 34 miles south of the water tower. Find the
distance between where the engineer lives and the bridge

There are 4 cups in a quart and 4 quarts in a ganon. jug of water? . how many cups are in a 5-gallon jug of water?

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?

According to the general equation for conditional probability if p(anb)=3/7 and p(b)=7/8 what is p(a i b)
