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.
Interesting question
Usually when you look at something like that construction, you think that AB has been bisected by PQ and that the two segments are perpendicular. They are perpendicular but nowhere is that stated. So the answer is C because all the other answers are wrong.
PQ is congruent AB is not correct. As long as the arcs are equal and meet above and below AB there is no proof of congruency. In your mind widen the compass legs so that they are wider than AB and redraw the arcs. You get a larger PQ, but it has all the original properties of PQ except size.
PQ is not congruent to AQ. How would you prove conguency? You'd have to put both lines into triangles that can be proved congruent. It can't be done.
The two lines are not parallel. They are perpendicular. That can be proven. They meet at right angles to each other (also provable).

First, let's find the area! The formula to find the area of a circle is πr²
πr²
3.14 · 4²
50.24 yds²
Now let's find the circumference. The formula for this is 2πr
2πr
2 · 3.14 · 4
25.12 yds
Hope this helps!
