Answer:
Time - independent variable
Score in test - dependent variable
Step-by-step explanation:
The relationship between Dependent and independent variables lies in the fact that, the outcome (dependent variable) relies on the value of the independent variable. Hence, the independent variable could be explained as a series of different possible values which has an effect on the value of the predicted variable. In an experiment, the dependent variable is predicted based on the input or value of the independent variable entered into the model.
Hence, in the scenario above, the study time could take up series of different possible values which could affect the score obtained in her tests. Hence, the test scores depends on the time dedicated to studying, making score obtained in test the dependent variable and the study time the independent variable.
Okay, here we have this:
Considering the provided expression, we are going to analize which exponential expression is equivalent, so we obtain the following:
As the property of the exponent of a multiplication says that it is equal to the product of each number raised to that power. We have this:

Finally we obtain that the correct answer is the option D.
