Opposite angles are equal, so we know that C=2x and D=5x+5 as well.
The sum of the interior angles of any quadrilateral is 360, so we have
So, the measures of the angles are
Since Louis jumped 270 times in 6 hours this means that she jumped:
45 times per hour.
Now we need to find how many times she jumped per minute to do this we have to remember that one hour has 60 minutes then we divide the number of jumps per hour by the 60 minutes, that is:
This means that she jumps 0.75 times per minute. Finally to find out how many times she jumped in foour minutes we multiply the 0.75 by 4:
Therefore, Louis jumped 3 times in four minutes.
Answer:
A) 2.58
B) 1.96
C) 1.65
Step-by-step explanation:
A hypothesis used to test that

Question:
The majority of U.S. car owners still buy American cars." Ideally, what would the sample be in the study that generated this stat?
answer choices
a) Everyone in the United States who owns a car
b) Everyone in the United States who owns an American car
c) A randomly selected group of car owners in the U.S.
d) A randomly selected group of Americans who own American cars
Answer:
A randomly selected group of car owners in the U.S.
Step-by-step explanation:
In this study, we are told the majority of U.S car owners still buy American cars. The sample in the study that generated this stat would be "a randomly selected group of car owners in the U.S".
⬤ Option A is incorrect, because collecting a sample from every car owner in U.S is impossible as the sample size would be rather tool large.
⬤ Option B is also incorrect because just like in option A, the sample size would be too large. Also this does not take into consideration those who don't use American cars
⬤ Option D is incorrect, this study deals with all car owners in the U.S, not Americans who own American cars. Therefore selecting a sample from Americans who own American cars would be wrong.
Answer:
Step-by-step explanation:
You don't say whether this is compound interest or simple interest.
I will assume it's compounding that interests you.
The appropriate formula is
A = P(1 + r)^t, where r is the interest rate as a decimal fraction, t is the time in years, and P is the original amount. Thus:
A = $1000·(1 + 0.05)^t, or A = $1000·(1.05)^t
Please note: There were apparently possible answer choices. Next time, please be sure to list such choices. Thank you.
