5 Hours
Step-by-step explanation:
Given :- 2 hours can be earned each day if she eats all of her vegetables and does all of her chores.
Saved hours at the start of the week = 3 hours
Hours earned in 4 days = 2 hours × 4
= 8 hours
Hours used in 4 days = 6 hours
Hours left after 4 days = Saved hours at the start of the week + Hours earned in 4 days - Hours used in 4 days
Hours left after 4 days = 3 + 8 - 6
= 5 hours

Answers
Answer:
m = 4
Step-by-step explanation:
ABCD ~ QRST, therefore, their corresponding side lengths brae proportional. This implies that:
10/m = 22.5/9
Cross multiply
m*22.5 = 9*10
22.5m = 90
Divide both sides by 22.5
m = 90/22.5
m = 4

a customer purchases windows for $15,000 using a credit card. If the interest is compounded monthly at a rate of 16% per year, how much interest will be charged at the end of three years?
Answers
Answer:
≈ $9164.35
Step-by-step explanation:
The future amount A is calculated as
A = P [tex](1+\frac{r}{n}) ^{nt}[/tex]
P is the Principle
r is interest rate
n is number of times per year compounding happens
t is the number of years
Here P = 15000 , r = 16% = 0.16, n = 12 , t = 3
A = 15000 [tex](1+\frac{0.16}{12}) ^{(12(3))}[/tex]
= 15000 ([tex](1.01333)^{36}[/tex]
≈ 24164.35
Interest paid = $24164.35 - $15000 = $9164.35
Answer:
The future amount A is calculated as
A = P (1+\frac{r}{n}) ^{nt}(1+nr)nt
P is the Principle
r is interest rate
n is number of times per year compounding happens
t is the number of years

Answers
Answer:7
Step-by-step explanation: 3 1/4 is equal to 13/4. When dividing fractions, you switch the numerator and denominator in the second fraction and change the symbol to a multiplication symbol. You then multiply straight across and then divide the top number by the bottom number. The whole number is how many times you can divide it equally

(b) Compute Ra2. (Round your answer to three decimal places.) Ra2 =
(c) Comment on the goodness of fit. (For purposes of this exercise, consider a proportion large if it is at least 0.55.)
The estimated regression equation provided a good fit as a large proportion of the variability in y has been explained by the estimated regression equation.
The estimated regression equation did not provide a good fit as a small proportion of the variability in y has been explained by the estimated regression equation.

Answers
Answer:
a) = 0.9739
b) = 0.969
c) option A is correct
Step-by-step explanation:
Given that:
sample size n = 30
SST = 1803
SSR = 1756
[tex]R^2 = \dfrac{SSR}{SST} \\ \\ R ^2 = \dfrac{1756}{1803} \\ \\ \mathbf{R^2 =0.9739}[/tex]
The adjusted [tex]R_a^2[/tex] is computed as:
[tex]R_a^2 = 1 - (\dfrac{n-1}{n-p})(1-R^2)[/tex]
where;
[tex]p = k+1 \\ p= 4+1 = 5[/tex]
[tex]R_a^2 = 1 - (\dfrac{30-1}{30-5})(1-0.9739)[/tex]
[tex]R_a^2 = 1 - (\dfrac{29}{25})(0.0261)[/tex]
[tex]R_a^2 = 1 - (1.16)(0.0261)[/tex]
[tex]R_a^2 = 1 -0.030276[/tex]
[tex]\mathbf{R_a^2 \simeq 0.969}[/tex]
