Answer:
D) Yes. The five trials are independent, have only two outcomes, and have the same P(success); n = 5, r = 2, p = 1/6.
Step-by-step explanation:
The Number of boxes = 6
Box containing a prize = 1
Probability of success, p = box containing a price / number of boxes = 1 /6
Number of trials = 5
Probability of success on exactly 2 trials, r = 2
Hence,
P(r = 2) = nCr * p^r * (1-p)^(n-r)
n = 5 ; r = 2 ; p = 1/6
Using a binomial probability calculator :
P(r = 2) = 0.1608
Answer:
5
Step-by-step explanation:
The sum of adjacent sides of the rectangle is half the perimeter, 50, so ...
... AH = 50-40 = 10
Then ...
... OP +QR = 10 = 2×OP . . . . . QR ≅ OP
... OP = 5 = PQ . . . . . . . . . . . . PQ ≅ OP
I think 1 hour about I do not have enough info to know of it is right or not.
12. The interest due will be
I = Prt = (1.0565·$12,465.00-1300.00)·0.064·(1/12) = $63.30 . . . . correct
13. The interest due will be
I = Prt = (1.0565·$12,465.00-1500.00)·0.05·(1/12) = $48.62
Then your savings is $63.30 -48.62 = $14.68 . . . . correct
14. The balance is 3489.90/5000.00 ≈ 69.8% of the card's credit limit. We do not know the "acceptable debt ratio percentage", so we cannot answer how much over that ratio this balance might be. (Usually such a debt ratio would be the ratio of total debt to income. Knowing just the credit card debt is insufficient information.)
