A group of students is arranging squares into layers to create a project. The first layer has 5 squares. The second layer has 10 squares. Which formula represents an arithmetic explicit formula to determine the number of squares in each layer? f(1) = 5; f(n) = 5 ⋅ d(n − 1), n > 0 f(1) = 5; f(n) = 5 ⋅ d(n + 1), n > 0 f(1) = 5; f(n) = 5 + d(n − 1), n > 0 f(1) = 5; f(n) = 5 + d(n + 1), n > 0

33% of college students say they use credit cards because of the rewards program. you randomly select 10 college students and ask each to name the reason he or she uses credit cards. find the probability that the number of college students who say they use credit cards because of the rewards program is (a) exactly two, (b) more than two, and (c) between two and five inclusive. if convenient, use technology to find the probabilities.

Which function has the domain x> -11?
