Which statement best describes the association observed in the graph?

• As the temperature increases, so does the number of ice cream cones sold.

• There is no relationship between the temperature and the number of ice cream cones sold.

• As the temperature increases, the number of ice cream cone cones sold decreases.

• As the temperature decreases, the number of ice cream cones sold increases.

The scatterplot represents the relationship between the temperature outside and the number of ice cream cones sold. Predict how many ice cream cones would be sold if the temperature outside was 100°F.

• about 80 ice cream cones

• about 90 ice cream cones

• about 100 ice cream cones

• about 120 ice cream cones

Predict the number of school districts and private school options that would be available in a city in Texas that has a population of 200,000.

Predict the population of a Texas city that has 1 schooling option.

• approximately 10,000

• approximately 20,000

• approximately 30,000

• approximately 40,000
