2. You are president of the high school band booster club. You have arranged for school's jazz band to perform at a local coffee shop for three hours. In exchance the performance, the booster club will receive three-quarters of the shop's gross receint during that three-hour period. a. Let r be the independent variable representing the gross receipts of the coffee shon during the performance. Let y be the dependent variable representing the share of the gross receipts that the coffee shop will donate to the band boosters. Write an equation relating r and y. b. Use the equation from part a to complete the following table. x, TOTAL GROSS RECEIPTS ($) 250 500 750 1000 y, BOOSTERS' SHARE ($) c. If the coffee shop presents you with a check for $650, what were the gross recepo during the performance? Estimate your answer using a numerical approach.

Visualize that two tributaries A and B at their confluence form a river C. Statistical properties of flow data for tributaries A and B indicate that tributary A has a yearly discharge rate smaller than its mean flow rate (?̅?) in 50% of the years while tributary B has a yearly discharge rate smaller than its mean flow rate (?̅?) in 60% of the time. In 70% of the years in which tributary A has a discharge rate smaller than its mean discharge rate (?̅?), tributary B also has a discharge rate smaller than its mean discharge rate (?̅?). Compute the probability that (i) both tributaries have a discharge rate smaller than their mean discharge rates, (ii) at least one tributary has a discharge rate smaller than its mean discharge rate, (iii) tributary A has a discharge rate smaller than its mean discharge rate given that tributary B has a discharge rate smaller than its mean discharge rate, (iv) at least one tributary has discharge rate higher than its mean discharge rate, and (v) probability…

An ice cream vendor at Disney World sells ice cream for $4 a scoop. Let R be the revenue, in dollars, for one night's sales and S represents the number of scoops of ice cream sold. Which of the following statements about this model is true? Select one: O The model can be written as R = 4S; revenue is the independent variable and scoops is the dependent variable. O The model can be written as R = 4S; revenue is the dependent variable and scoops is the independent variable. O The model can be written as S = 4R; revenue is the independent variable and scoops is the dependent variable. O The model can be written as S = 4R ; revenue is the dependent variable and scoops is the independent variable. O The model can be written as 4S = 4R; both revenue and scoops are the independent variables. DE DII 80 F8 F7 F5 F6 F2 F3 F4
