c. positive relationship; as the outside temperature increases, the amount of the heating bill increases.
d. negative relationship; as the outside temperature decreases, the amount of the heating bill increases
please select the best answer from the choices provided

Explanation:

A negative relationship means that as one variable increases, the other decreases. When the outside temperature decreases, people use more heating to keep warm, so the heating bill amount increases. This shows an inverse (negative) relationship.

Answer:

D. negative relationship; as the outside temperature decreases, the amount of the heating bill increases
