Adam earned a score of 57 on Exam A that had a mean of 63 and a standard deviation of 20. He is about to take Exam B that has a mean of 400 and a
standard deviation of 100. How well must Adam score on Exam B in order to
do equivalently well as he did on Exam A? Assume that scores on each exam
are normally distributed.

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.
