When tossed, head shows up 4 times more considera con that is not fair. (4 marks) often than tails. assign valid probabilities to this experiment 18. if p(e)-0.25, p(f)-0.3 and p(enf)-0. determine the probability of p(euf). [4 marks)

Express -5 2/5 as an improper fraction.

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.
