(Exponential Models MC)The level of fame of an artist is assigned from 1 to 10, with 10 signifying the most famous artist. Data are collected about selling prices for painting and the level of fame of the artists. The model ŷ = 948.25(2.998)x is calculated, where x represents the artist’s fame score and ŷ represents the predicted selling price of the painting. Use the model to predict the selling price of a painting whose artist’s fame is a level 4.

  (Linear Models MC)A theater manager collected data about ticket prices and attendance for an upcoming opening night. The results were used to calculate the model ŷ = –9.34x + 602.45, where x represents the selling price in dollars and ŷ represents the predicted number of tickets sold. Interpret the slope of the model in the context of the problem.

(Linear Models LC)The price for chicken and the amount sold are recorded in the table. Chicken price per pound (in dollars) 1.52 1.89 1.99 2.14 2.56 2.78 2.98 3.12 3.49 Chicken sold (in pounds) 25 22 22 20 19 17 15 10 10 The equation ŷ = –7.828x + 37.321 models the data, where x represents the chicken price per pound and ŷ represents the predicted number of pounds sold. For which of the following prices would predicting the amount sold be an extrapolation?
