It’s D 69x3= 207
6% of 207 = 12.42
2% of 207 = 4.14
1% of 207 = 2.07
12.42 + 4.14 + 2.07 = 18.63
207+18.63 = 225.63
Answer:
d and e
Step-by-step explanation:
To factor 4x² + 17x - 15
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term, that is
product = 4 × - 15 = - 60 and sum = + 17
The factors are + 20 and - 3
Use these factors to split the middle term
4x² + 20x - 3x - 15 ( factor by grouping the first/second and third/fourth terms )
= 4x(x + 5) - 3(x + 5) ( take out the common factor (x + 5) )
= (x + 5)(4x - 3) → d/e
Answer:
21.1%
Step-by-step explanation:
(25 - 24.3) / 1.2 = 0.5833 z score = 78.9%
You need the percent that spend more than 25 hrs per week, so 100 - 78.9 = 21.1%
Answer:
Step-by-step explanation:
The formula for determining compound interest is expressed as
B = p(1 + r)^t
where
B is the balance (final amount),
p is the principle (starting amount),
r is the interest rate.
t is the time in years.
From the information provided,
p = $1
r = 10% = 10/100 = 0.1
t = 3 years
The balance in 3 years would be
A = 1(1 + 0.1)^3
A = 1(1.1)^3
A = $1.331
The interest earned after 3 years is
1.331 - 1 = $0.331
Rounding up to the nearest tenth, it becomes $0.3
