The bar graphs show U. S. film box-office receipts, in millions of dollars, and box-office admissions, in millions of tickets sold, for five selected years.
Use the information and a calculator to solve exercises 87-88.
87.
a. use the data displayed by the bar graphs to find the average admission charge for a film ticket in 1990. Round to two decimal places, or to the nearest cent.
b. use the models to write an algebraic expression that describes the average admission charge for a film ticket x years after 1980.
c. use the model from part (b) to find the average admission charge for a film ticket in 1990. Round to the nearest cent. Does the model underestimate or overestimate the actual average charge that you found in part (a)? By how much?
d. Can the polynomial division for the model in part (b) be performed using the methods that you learned in this section? Explain your answer.

- The U.S. Geological Survey monitors and reports on earthquakes, providing daily real-time, worldwide earthquake lists. Some of the information for four of the 105 earthquakes of magnitude 1.5 or greater that occurred on May 10, 2013, is shown in the following table. Magnitude is given on the Richter scale and NST stands for the number of stations that reported the activity on the same earthquake. Complete parts (a) through (e) below.

- 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 = 958.25(2.988)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 5. $143,163 $192,441 $228,235 $958,250arrow_forwardThe accompanying table displays information about the number of births (in thousands) and the number of deaths (in thousands) for certain years.

Trust in government hit an all-time low of 14% in 2014, while trust in the media bottomed out at 32% in 2016. The bar graph shows the percentage of Americans trusting in the government and the media for five selected years. Use this information to answer parts a-c. a. Use the information in the graph to estimate the yearly loss in the percentage of people trusting in government. The yearly loss in the percentage of people trusting in government is 36 %.
