Answer:
6.2%
Step-by-step explanation:
Credit rating is an evaluation of the credit risk of a borrower, that how often a person is going to repay their debt, by credit rating it predicts the ability of the debtor to payback.
Mike has credit rating = 720
Tyler has credit rating = 560
Both are approved for loan. Mike's Credit score is higher, which means he is a much safer debtor as compared to Tyler. Mike will be able to pay back much easily than Tyler. Therefore Mike interest rate is 3.2%
Interest rate of Tyler is higher as he is not that trusted and has low Credit rating. Tyler is approved for a loan that charged 3 percentage points higher because of his inferior credit rating so it interest on the loan will be
Interest = 3.2%+3% = 6.2%
Setup is
y = k/x
8 = k/3
k = 24
Now use 6 for y
6 = 24/x
x = 24/6 = 4 or A
12 = 30% of what
12 = 0.30x
12 / 0.30 = x
40 = x.......so 12 is 30% of 40
Answer:
a) 3C1 * 12 C1 / 15 C2
b) 1 - 12C2 / 15C2
Step-by-step explanation:
Được
Viên bi đỏ = 3
Viên bi trắng = 5
Viên bi xanh = 7
Hai quả bóng được rút ra một cách ngẫu nhiên
a) Có 1 bi đỏ
3C1 * 12 C1 / 15 C2
b) Có ít nhất 1 viên bi đỏ trong số 2 viên lấy ra.
Số kết quả của việc chọn hai quả bóng trong số 15 quả bóng = 15 C2
Số kết quả của việc chọn 0 quả bóng đỏ = 15C12
Xác suất chọn được ít nhất 1 viên bi đỏ = 1 - 12C2 / 15C2
