3. Two Distances. The distance between the two towers is 38 miles. From the western cell tower a phone is 21 miles away, and from the eastern cell tower the same phone is 52
miles away. Determine the angles and the directions from each of the cell towers. Sketch a
diagram

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e.g. 98.7654). x f(x) 0 1 2 3

Which one is the correct answer, and why?
