Answer:
Base: , Height:
Step-by-step explanation:
Let the base be . Then the height is .
By the area of a triangle theorem, we have that .
Multiplying by and expanding gives , so . We see that this quadratic factors into . Because the base is a side length and must be positive, we have that the base is .
The height is then .
Answer:
10 units
Step-by-step explanation:
We look at the number -7 on the number line and count how many units it is from 3
it looks like you can say 3 - (-7 ) = 10

Answer:
"If we examine the proportion of students at their campus who still live at home with their parents, how likely is that proportion to be more than 36%?"
Step-by-step explanation:
The third option. When running the hypothesis test, you are comparing your sample size (of the campus) to the known sample size (the results given by the Pew Research Center). The results of the test give you the probability of the sample happening by random chance. We always test for equality (the sample being equal to the population), so if we reject the null, there will be evidence to suggest that the population proportion is actually more, given that the sample is an unbiased representation of the actual population
Answer:
a) $32,000
b) 9/25
c) 36%
Step-by-step explanation:
Hello!
A) How much did you save?
Let's see. In order to find the savings, we must subtract the new price from the original.
You saved $32,000 (a pretty good deal!)
B) What fraction of the original price was this?
To find the fraction, we must divide the new price from the original.
- 18,000/50,000
- 9,000/25,000 => SImplify
- 9/25 => Simplify
It's 9 twenty-fifths of the original price.
C) What fraction of the original price was this?
Convert the fraction to percent
- 9/25
- 9*4/25*4 => Denominator of 100
- 36/100
- 36%
