Many stores run "secret sales": Shoppers receive cards that determine how large a discount they get, but the percentage is revealed only after the purchase has been totaled at the cash register. The store is required to reveal (in the fine print) the distribution of discounts available. Are each of these probability assignments possible. Which of these probability assignments are legitimate?

Probabilites
10% off 20% off 30% off 50% off
a. 0.20 0.20 0.20 0.20
b. 0.50 0.30 0.20 0.10
c. 0.80 0.10 0.05 0.05
d. 0.75 0.25 0.25 -0.25
e. 1.00 0 0 0

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
