Answer for Question 3:
Double-line graphs are typically used to compare two sets of data over a period of time. Looking at the options provided, the type of information best suited for display on a double-line graph is option D: average prices of two car models at five dealerships.
Answer for Question 4:
To determine how many students ran more than 30 miles, we need to count the number of data points that have a value greater than 30 on the stem-and-leaf plot. From the given stem-and-leaf plot, there are 5 data points with values greater than 30 (6, 42, 46, 47, and 48). Therefore, the answer is B: 5.
Answer for Question 5:
To determine how many residents are older than 80, we need to count the number of data points with stems greater than 8 on the stem-and-leaf plot. From the given stem-and-leaf plot, there are 11 data points with stems greater than 8. Therefore, the answer is B: Sandy Ridge, 13; Autumn Care, 11.
