A pizza is removed from an oven at a temperature of 425°F. After 15 minutes, it has cooled to 200°F. Use a continuous exponential decay model to approximate the rate of decay as a percent.

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.
