Dependent quantity: quantity of water in a boiler.

Dependent quantity: quantity of water in a boiler.

Correct Answer is : quantity of water

Step: 1

Independent quantity is the input and the dependent quantity is the output of the situation.

Step: 2

Independent quantity: Temperature of the oven

Dependent quantity: weight for a 2-pound roast

Dependent quantity: weight for a 2-pound roast

Correct Answer is : weight of a 2-pound roast.

Hours of sleep ( | 5.5 | 6.0 | 6.5 | 7.0 | 7.5 | 8.0 | 8.5 | 9.0 | 9.5 | 10.0 | 10.5 | 11.0 |

Minutes of nap time ( | 150 | 140 | 130 | 120 | 110 | 100 | 90 | 80 | 70 | 60 | 50 | 40 |

Step: 1

Independent variable is the input and the dependent variable is the output of the situation.

Step: 2

From the given function, independent variable is hours of sleep and the dependent variable is minutes of nap time.

Step: 3

Among the choices, "minutes of nap time and hours of sleep" is the correct answer.
