Describe the surface whose equation in cylindrical coordinates is z = 5r. SOLUTION The equation says that the z-value of each point on the surface is the same as 5r, the distance from the point to the z-axis. Because θ doesn't appear, it can vary. So any horizontal trace in the plane z = k (k > 0) is a circle of radius r = Incorrect: Your answer is incorrect. . These traces suggest that the surface is a cone. This prediction can be confirme

Match the vocabulary to the proper definition. in probability, two events in which 1. conditional probability the outcome of one event is independent of the outcome of a second event. 2. dependent events in probability, two events in which the outcome of one event is dependent on the outcome of a second event. the probability of an event in which the outcome of the event is conditional on the outcome of one or more different events. 3. independent events
