There are 30 billiard balls in a bag: some have only a red stripe, some only have a blue stripe, still others have both a red and a blue stripe. Anna draws 5 balls simultaneously: 2 have only the red stripe, 2 have both the red stripe and the blue stripe and one has only the blue stripe. Which are the minimum and maximum values of the difference between the number of balls that have only one type of strip? in correspondence with these values, how many balls would have both stripes?

1. if events a and b are non-overlapping events, how do you find the probability that one or the other occurs? 2. what does it mean if p(a or b) equals 1?

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.
