(Addition and Multiplication Rules for Probability MC)A cafe offers 9 types of coffee, 3 types of tea, and 4 types of soft drinks. Determine the total number of beverages from which a customer can choose.

(Interpreting Data Distributions MC)The display shows data collected from a group of volunteers who attended a community service meeting.What percentage of the volunteers were aged 11 to 24?

(Set Operations and Relations MC)Given U = {g, h, i, j, k, l, m, n, o, p}, A = {h, j, m, n, o}, and B = {h, i, k, m, o, p}. If A′ ∩ B′ = {g, l}, determine (A ∪ B)′.

(Linear Models MC)Data collected from real estate agents were used to calculate the model ŷ = 89x + 102,790, where x represents the size of a house in square feet and ŷ represents the predicted selling price of the house in dollars. Using the model, predict the size of a house that sells for $350,000.

(Logic Operations and Equivalence MC)Use the statements and truth table to determine which statements are equivalent.p: It is a burger.q: It has ketchup on it. p q ~p ~q p → q ~q → ~p q → p T T F F T T T T F F T F F T F T T F T T F F F T T T T T

(Exponential Models MC)A music streaming platform used data to calculate the model ŷ = 803.3(1.138)x, where x represents the number of days since a song was released and ŷ represents the predicted number of downloads. Interpret the percent rate of change of the model in the context of the problem.

Identify the “cup.”

(Combinations and Permutations LC)Calculate the number of combinations, given n = 17 and r = 3.

(Comparing Data HC)Salary data were gathered from two companies and displayed in the stacked box plots.Part A: Compare the appropriate measure of center based on the shapes of the distributions. Explain your choice. (3 points)Part B: Compare the appropriate measure of variability based on the shapes of the distributions. Explain your choice. (3 points)Part C: Which company is better to work for if you are an average worker? Justify the answer. (4 points)

(Linear Models MC)Data were collected from several hospitals about the charge for medical procedures and the popularity of the procedures. The results were used to calculate the model ŷ = –58.25x + 927, where x represents the cost of the procedure in thousands of dollars and ŷ represents the predicted number of procedures performed. Using the model, how much would a procedure cost that is predicted to be performed 400 times?
