230 is written as 2.3 × 10^2
Answer: 
Step-by-step explanation:
Let p be the population proportion for the graduates from private nonprofit colleges in the region had at least one outstanding student loan at the time of graduation.
Given : Tristan is an administrator for a private nonprofit college and read a surprising statistic that 74% of graduates from private nonprofit colleges in the region had at least one outstanding student loan at the time of graduation.
i.e. 
He believes that percentage is high and claims that the proportion of graduates at his college is less than the regional rate.
i.e. 
Since, the null hypothesis is a statement which always takes equal sign or generally shows " no difference " where as alternative hypothesis takes unequal signs.
Then, the null and alternative hypotheses for this hypothesis test :-

Answer:
x ≤ 17
Step-by-step explanation:
Pick up fee = 2.80
Cost per mile = 1.25
Total cost = $24.05
Number of miles ride, x
Pickup fee + mile per ride * number of ride ≤ total cost
2.80 + 1.25x ≤ 24.05
1.25x ≤ 24.05 - 2.80
1.25x ≤ 21.25
x ≤ 17
Number one of miles ride x ≤ 17
Answer:
(2,1)
Step-by-step explanation:
So the first thing you want to do is substitute. You want to plug in the equation for y in for the y value above.
So you would do 3x+4(x-1)=10. As you can see we took the bottom equation and put it in for the top equation. We did this so we only have x s and no y s.
Now you would solve. You would distribute first. You would get 3x+4x-4=10. Now combine like terms. 3+4 is 7 so you would get 7x-4=10.The next thing you want to do is get the 7x by itself so move the 4.You would get 7x=14. Now divided both sides by 7 because you want to get the x by itself.
You would get x=2. Now for the y value just plug it in for an equation above. The easier one would be y=x-1. y=(2)-1 will equal 1. You write your final answer in (x,y) style. Your final answer will then be (2,1)
