Which of the following statements describes a relationship that is linear?
- The price of houses in the neighborhood is increasing at the rate of 12% per year.
- The number of bacteria is increasing at the rate of 18% per minute.
- The temperature is increasing at the rate of 7° degrees per hour.
- The number of cars in the parking lot is decreasing at the rate of 15% per hour.
Homework Answers
C. The temperature is increasing at the rate of 7° degrees per hour. describes linear relationship because every hour the decrease is by 7 and not any percentage value

Biologists have noticed that the chirping rate of crickets of certain species is related to temperature, and the relationship appears to be very nearly linear. A cricket produces 113 chirps per minute at 70 degrees Fahrenheit and 173 chirps per minute at 80 degrees Fahrenheit. What is the slope of the graph of a linear equation that models the temperature T as a function of the number of chirps per minute N?

There is a linear relationship between the number of chirps made by the striped ground cricket and the air temperature. A least-squares fit on some data collected by abiologist gives the model y(hat) = 25.2 = 3.3x, 9<x<25, where x is the number of chirps per minute and y(hat) is the estimated temperature in degrees Fahrenheit.What is the estimated increase in temperature that corresponds to an increase of 5 chirps per minute?(a) 3.3 Fahrenheit(b) 16.5 Fahrenheit(c) 25.2 Fahrenheit(d) 28.5 Fahrenheit(e)...

Which of the following statements about the relationship between pressure and temperature is true? Increasing the temperature would make some of the gas escape from the balloon, decreasing the volume. As temperature increases, the volume of a gas decreases. As temperature increases, the volume of a gas also increases. The volume of a gas is affected by temperature changes, but it is not possible to predict how it is affected The volume of a gas is unaffected by temperature changes.
