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.

Because the sample mean for students with a grade point average of 3.0–4.0 is

Tammy graphs the function h(x) = x² + 9. Sarah graphs the function g(x) = (x + 9)². Which statements are true regarding the two graphs? Select three options.


Tammy’s graph is a vertical translation of f(x) = x².

Sarah’s graph is a vertical translation of f(x) = x².

Tammy's graph moved 9 units from f(x) = x² in a positive direction.

Sarah's graph moved 9 units from f(x) = x² in a positive direction.

Tammy’s graph has a y-intercept of 9.

Sarah's graph has a y-intercept of 9.

The graph below shows the winter precipitation in Arizona from 1995 to 2002. It also shows the survival rates of Arizona pronghorn fawns for the same period.

Which two years had the most precipitation?

• Which two years had the best survival rates for fawns?

• Using your knowledge of biotic and abiotic factors and information from the graph, give two reasons why precipitation and fawn population are linked.

• Predict what would happen to the fawn population if the precipitation rate continues to go downward in 2003.

Cara likes candles. She also likes mathematics and was thinking about using algebra to answer a question she had about two of her candles. Her taller candle is 16 cm tall. Each hour it burns makes the candle lose 2.5 cm in height. Her short candle is 12 cm tall and loses 1.5 cm in height for each hour that it burns.

Write an equation for both candles and solve it by either substitution or elimination.

(If someone could please help me out with this, I would really appreciate it. I've been trying to do this for days now and I just can't figure it out..)
(By the way, the equation for the 16 cm candle is y = -2.5x + 16, and the equation for the 12 cm candle is y = -1.5x + 12, I just don't know how to solve it using substitution or elimination.)​

Solve the equation 18y – 17 = 7 for y.
