Answer:

The dependent variable is number of calories burnt.

Step-by-step explanation:

The dependent variable of an experiment is the variable under study, i.e. it is the variable that is being observed for any changes, when the other variables are changed.

The independent variable is the variable that is being altered to observe the changes in the dependent variable.

A dependent variable can be affected by one or more than one independent variables.

In this case, the data provided represents the number of calories Maggie burned based on the number of miles she ran.

So, the amount of calories burnt is dependent upon the number of miles covered running.

So, the dependent variable is the number of calories burnt and the independent variable is the number of miles she run.

Thus, the dependent variable is number of calories burnt.
