Factor the following polynomial: 11mn^3+9m^2n^2-7m^3n

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.

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
