6 7.6 Two samples of water of equal mass are heated to 60 degrees Celsius (deg C). One sample is poured into an insulated container, and the other sample is poured into a non-insulated container. The samples are then left for 70 minutes to cool in a room having a temperature of 25 deg C. The graph above shows the temperature of each sample at 10-minute intervals. Which of the following statements correctly compares the average rates at which the temperatures of the two samples change?

A In every 10-minute interval, the magnitude of the rate of change of temperature of the insulated sample is greater than that of the non-insulated sample. B In every 10-minute interval, the magnitude of the rate of change of temperature of the non-insulated sample is greater than that of the insulated sample. C In the intervals from 0 to 10 minutes and from 10 to 20 minutes, the rates of change of temperature of the insulated sample are of greater magnitude, whereas in the intervals from 40 to 50 minutes and from 50 to 60 minutes, the rates of change of temperature of the non-insulated sample are of greater magnitude. D In the intervals from 0 to 10 minutes and from 10 to 20 minutes, the rates of change of temperature of the non-insulated sample are of greater magnitude, whereas in the intervals from 40 to 50 minutes and from 50 to 60 minutes, the rates of change of temperature of the insulated sample are of greater magnitude.

7 7.7 The graph below shows the total number of music album sales, in millions, each year from 1997 through 2009. Based on the graph, which of the following best describes the general trend in music album sales from 1997 through 2009?

A Sales generally increased each year since 1997. B Sales generally decreased each year since 1997. C Sales increased until 2000 and then generally decreased. D Sales generally remained steady from 1997 through 2009.

8

8 7.8 Michael swam 2,000 yards on each of eighteen days. The scatterplot above shows his swim time and corresponding heart rate after each swim. The line of best fit for the data is also shown. For the swim that took 34 minutes, Michael's actual heart rate was about how many beats per minute less than the rate predicted by the line of best fit?

A 1 B 2 C 3 D 4

9

9 7.9 A curator at a wildlife society created the scatterplot above to examine the relationship between the gestation period and life expectancy of 10 species of animals. What is the life expectancy, in years, of the animal that has the longest gestation period?

A 3 B 4 C 8 D 10

10

10 7.9 A curator at a wildlife society created the scatterplot above to examine the relationship between the gestation period and life expectancy of 10 species of animals. Of the labeled points, which represents the animal for which the ratio of life expectancy to gestation period is greatest?

A A B B C C D D

11

11 7.11 Wesley went to an amusement park with his family. He paid for his own admission ticket and all of the rides he rode. The scatterplot shows possible amounts that he could have paid. If a line of best fit is used to model the data, the equation of the line would be \(y=3r+b\). In this scenario, what does 3 represent?

A The cost of one ride B The number of rides Wesley rode C The cost of the admission ticket D The number of hours Wesley stayed at the park

5 minutes remaining
