Answers

Answer 1
Use the Pythagorean Theorem since triangle ABC is a right triangle.

Pythagorean Theorem: a^2+b^2=c^3.

Substitute the 2 side lengths in and find the 3rd side length:

15^2+10^2=c^2.

225+100=c^2 by exponents.

325=c^2 by addition.

18.027=C by Square Root P.O.E.

C=18.027 by Symmetric P.O.E

The 3rd length is 18.027 or Square root of 36.

Garret studies number of hours sleep per night among students who have a grade point average of 3.0–4.0 versus students who have a grade point average of 2.0–3.0.

His theory is that students who get more sleep will have a higher grade point average than students who get less sleep because they are more rested and, therefore, better able to concentrate.

In his samples, the mean number of hours of sleep students with a grade point average of 3.0–4.0 received each night was 6.8. The mean number of hours of sleep students with a grade point average of 2.0–3.0 received each night was 6.4.

Assuming there are no outliers or skew, do the results support Garret's theory?

Select from the drop-down menus to correctly complete the statements.

Since the samples were large and randomly chosen, we can use the samples to understand the populations.
