- College students are graduating with the highest debt burden in history. The bar graph shows the mean, or average, student-loan debt in the United States for five selected graduating years from 2001 through 2013. Here are two mathematical models for the data shown by the graph. In each formula, D represents mean student-loan debt, in dollars, x years after 2000. The Model 1 is, D = 1188x + 16,218 and the Model 2 is D = 46x2 + 541x + 17,650. Solve, a. Which model better describes the data for 2001?b. Does the polynomial model of degree 2 underestimate or overestimate the mean student-loan debt for 2013? By how much?arrow_forwardThe boxplot below shows salaries for Actuaries and CPAs.

One aspect of the study was to develop a model that could be used to predict a bear's weight (since it is not practical to weigh bears in the field). One variable thought to be related to weight is the length of the bear. The accompanying data represent the lengths and weights of 12 American black bears. Complete parts (a) through (d) below.

- Rhonda took a ribbon which was originally 81 cm in length. She cut the ribbon in thirds and measured each piece, recording the data in the table at right. She continued to cut each piece of ribbon into thirds and record the lengths. Theoretically, how many cuts would it take to reach a length of about 0.037 cm for one piece of ribbon?

- As the new owner of a supermarket, you have inherited a large inventory of unsold imported Limburger cheese, and you would like to set the price so that your revenue from selling it is as large as possible. Previous sales figures of the cheese are shown in the following table. Price per Pound, p $3.00 $4.00 $5.00 Monthly Sales, q (pounds) 404 281 225 (a) Use the sales figures for the prices $4 and $5 per pound to construct a demand function of the formq = Ae-DP, where A and b are constants you must determine. (Round A and b to two significant digits.) q = (b) Use your demand function to find the price elasticity of demand at each of the prices listed. (Round your answers to two decimal places.) p = $3 E = p = $4 E = p = $5 E = (c) At what price should you sell the cheese to maximize monthly revenue? (Round your answer to the nearest cent.)

Situation: According to literacy reports in the city of Gotham, youth literacy went up to 7% since 2012. Here is the data: In 2010, only 43% of the youth population was literate. In the next census at 2015, it went up by 2%. After five years, the literacy rate was at 47%.

The diversity index in the United States varies widely from region to region, from as high as 81 in Hawaii to as low as 11 in Vermont. The bar graph shows the national diversity index for the United States for four years in the period from 1980 through 2010.The data in the graph can be modeled by the formulaD = 0.005x2 + 0.55x + 34,where D is the national diversity index in the United States x years after 1980. According to the formula, what was the U.S. diversity index in 2010? How does this compare with the index displayed by the bar graph?arrow_forward
- Americans' trust in government and the media has generally been on a downward trend since pollsters first asked questions on these topics in the second half of the twentieth century. 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.
