The number of people who enter an elevator on the ground floor is a poisson random variable with mean 10. if there are n floors above the ground floor, and if each person is equally likely to get off at any one of the n floors, independently of where the others get off, compute the expected number of stops that the elevator will make before discharging all of its passengers.

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
