The number of bags of chips sold in a month are tracked and follows a normal distribution after 2 years the mean is found to be 2.4million with a standard deviation of 0.3 million. what is the chance that 1.8 and 2.1 million bags are sold in a random month

Select all of the following expressions that are equal to 2.5.

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.
