A) 26.7%
B) 40%
The probability of A is given by 4/6(2/5), since this is done without replacement; there are 4 blue marbles out of 6. When the first one is gone, there are 2 red out of 5 remaining.
The probability of B is given by 4/6(3/5), since this is done without replacement; there are 4 blue marbles out of 6. When the first one is gone, there are 2 blue out of 5 remaining.
Alright so since the area of one side of the door is 2,880 inches squared and he wants to paint both sides, you must multiply that by 2.
2880 * 2 = 5760
Since he wants to put 2 coats of paint, this essentially means he wants to paint over everything twice so you must multiply by 2 once more.
5760 * 2 = 11520
This being the total surface area we are going to need to paint. So now we must discover the least amount of money Luke must pay. Knowing we need to cover 11,520 inches worth of door:
4400 * 2 = 8800
8800 + 2200 = 11000
This means we either need to pay another $7 or just buy three gallons.
Best option: Purchase 3 gallons of paint costing 30$
30$
<u>Missing step in this proof</u> :-
Step 3 :-
→ (Option B)
Statement - DE is parallel to AC
Reason - AB is a traversal cutting DE and AC.
Answer:
Assumptions before conduction hypothesis test are mentioned below in the explanation.
Step-by-step explanation:
As this question is incomplete, and I will try my best to answer this question.
We are asked in this question to write the assumptions that we check before conducting the hypothesis test.
Solution:
Assumptions of hypothesis test:
1. We have to make assumption that all the observations are independent.
2. Secondly, we need to take assumption that, all the parent population of the data reflects normal distribution.
3. Furthermore, we need to assume that experimental error or random error is independently identical and normally distributed with mean "0" and variance of (σ^2).
Above are the assumptions that we should check before conducting hypothesis test.
