Howmet Corporation needs $200,000 in 5 years.

Bogdan [553]

:)
The formula of the future value of annuity ordinary is
Fv=pmt [(1+r/k)^(kn)-1)÷(r/n)]
So we need to solve for pmt
Pmt=fv÷[(1+r/k)^(kn)-1)÷(r/n)]
Pmt=200,000÷(((1+0.10÷4)^(4×5)
−1)÷(0.10÷4))=7,829.43...answer

Hope it helps

Each face of cabinet 413s is in the shape of a rectangle. What is the volume of model 413s in cubic feet

Tasya [4]

Each side of the model of 413s is rectangular shaped.
So, by this statement we got to know that the model is in cuboid shape.
Hence, its volume will be (length×width×height) cubic feet.

Which equation represents a line that passes through (4, left-parenthesis 4, StartFraction one-third EndFraction right-parenthes

lina2011 [118]

Answer:

$y-\frac{1}{3}=\frac{3}{4}(x-4)$

Step-by-step explanation:

we know that

The equation of the line into point slope form is equal to

$y-y1=m(x-x1)$

In this problem we have

$(x_1,y_1)=(4,\frac{1}{3})$

$m=\frac{3}{4}$

substitute the given values

$y-\frac{1}{3}=\frac{3}{4}(x-4)$

therefore

y minus StartFraction one-third EndFraction equals StartFraction 3 Over 4 EndFraction left-parenthesis x minus 4 right-parenthesis.(x – 4)

Each year a town holds a winter carnival this year 40% of the attendees were children under the age of 10 if 304 children under

tatuchka [14]

Answer:

760 attendees

Step-by-step explanation:

40% of the attendees is 304. That means you can add 304 to 304 (304 x 2) to get 608. To get the last 20%, divide 304 by 2, because 40(%) divided by 2 is 20(%). The answer to that is 152. Now, add it all up. 608 + 152 = 760.

In conclusion, there were 760 attendees at the carnival.

A survey was conducted in a large city to investigate public opinion on banning the use of trans fats in restaurant cooking. A r

Answer:

There is no enough evidence to claim that there is a difference between the two population proportions.

Step-by-step explanation:

We have to perform an hypothesis testing for a difference between two population proportions.

The null hypothesis will state that both proportions are the same, and the alternative hypothesis will state that they differ. This would be than a two-side hypothesis test.

We can write this as:

$H_0: \pi_1-\pi_2=0\\\\H_a:\pi_1-\pi_2\neq0$

The significance level for this test is 0.05.

The sample of city residents with school-age children has a sample size n1=230 and a sample proportion p1=0.41

$p_1=X_1/N_1=94/230=0.41$

The sample of city residents without school-age children has a sample size n2=341 and a sample proportion p2=0.51

$p_2=X_2/N_2=147/341=0.43$

The weighted p, needed to calculate the standard error, is the weighted average of both sample proportions:

$p=\dfrac{n_1p_1+n_2p_2}{n_1+n_2}=\dfrac{230*0.41+341*0.51}{230+341}=\dfrac{94+147}{571} =\dfrac{241}{571}=0.42$

The standard error of the difference of proportions can now be calculated as:

$\sigma_p=\sqrt{\dfrac{p(1-p)}{n_1}+\dfrac{p(1-p)}{n_2}}=\sqrt{\dfrac{0.42*0.58}{230}+\dfrac{0.42*0.58}{341}}\\\\\\\sigma_p=\sqrt{\dfrac{0.2436}{230}+\dfrac{0.2436}{341}}=\sqrt{0.00106+0.00071}=\sqrt{0.00177}\\\\\\\sigma_p=0.042$

The test statistic z is:

$z=\dfrac{p_1-p_2}{\sigma_p}=\dfrac{0.41-0.43}{0.042}= \dfrac{0.020}{0.042}= 0.476$

The P-value for this two side test and this value of the z-statistic is:

$P-value=2*P(z>0.476)=0.634$

The P-value is bigger than the significance level, so the effect is not significant. The null hypothesis failed to be rejected.

There is no enough evidence to claim that there is a difference between the two population proportions.
