The function f(x) = -0.3x2 + 2.5x + 5 can be used to approximate the distance a thrown ball is from the ground, where x is
the distance between the ball and the person throwing the ball. the mathematical domain of the function is all real
numbers.
the reasonable domain of the function is when 0

Arestaurant gives out a scratch-off card to every customer. the probability that a customer will win a prize from a scratch-off card is 25%. design and conduct a simulation using random numbers to find the experimental probability that a customer will need more than 3 cards in order to win a prize. justify the model for your simulation, and conduct at least 10 trials.
