Alexandra is setting up tables for a party. Three of the tables are covered with red tablecloths, and nine of the tables are covered with white tablecloths. Guests will be randomly seated at the tables when they arrive. What is the probability that the first guest to arrive will be seated at the table with a red tablecloth?

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.
