How to define an exponential function?

An exponential function is defined as follows:

y = ab^x.

In which:

a is the initial value.b is the rate of change.

For this problem, the function is defined as follows:

y = 30000(1.04)^x.

In which:

x is the number of years since 2012.y is the cost in x years after 2012.

C(3) represents the cost in 2015 and is obtained as follows:

C(3) = 30000(1.04)^3 = $33,746.

C(-5) represents the cost in 2007 and is obtained as follows:

C(-5) = 30000(1.04)^(-5) = $24,658.

Answers

Answer:

4/15

Step-by-step explanation:

Bag A

3 red marbles and 6 blue marbles.  = 9 marbles

P(blue) = blue/total =6/9 = 2/3

Bag B

Answers

Answer:

$10.00 per hour

Step-by-step explanation:

Overhead application rate which is also known as overhead absorption rate on the basis on labor hours is the total budgeted overhead  for 2019 which is $900,000 divided by the expected production of 90,000 labor hours for the year.

overhead application rate=$900,000/90,000=$10 per hour

This implies that for every one hour worked overhead cost of $10 would be added to the other costs incurred.

The correct option then is the third option of $10.00 per hour

Jeanine’s swimming pool has a diameter of 27 feet. Surrounding the pool is a deck that extends 5 feet from the edges of the pool. Jeanine wants to paint the deck and then put a fence around it. Paint costs $0.85 per square foot and fencing costs $8.25 per foot. How much will it cost Jeanine to paint the deck and add fencing?

Answers

Answer:

The total cost of painting the deck and add fencing is $1,386.79.

Step-by-step explanation:

Consider the diagram below.

The smaller circle represents Jeanine’s swimming pool with diameter,

d = 27 feet.

And the outer circle represents the deck.

The width of the deck is 5 feet.

Then the diameter of the bigger circle is:

D = 27 + 5 + 5 = 37 feet

It is provided that Jeanine wants to paint the deck and the paint costs $0.85 per square foot.

The cost of painting the deck can be computed using the formula:

Cost of painting = Area of Deck × Cost of paint/square foot

Compute the area of the deck as follows:

Area of Deck = Area of bigger circle - Area of smaller circle

                      [tex]=\pi R^{2}-\pi r^{2}\\\\=\pi(R^{2}-r^{2})\\\\=\frac{22}{7}\times [(\frac{37}{2})^{2}-(\frac{27}{2})^{2}]\\\\=502.86[/tex]

Then the cost of painting the deck is:

Cost of painting = Area of Deck × Cost of paint/square foot

                           [tex]=502.86\times \$0.85\\=\$427.431\\\approx \$427.43[/tex]

The cost of painting the deck is $427.43.

Now Jeanine also wants to put a fence around the deck.

The cost of fencing is, $8.25 per foot.

The cost of putting the fence can be computed using the formula:

Cost of putting the fence = Circumference of the big circle × Cost of fencing

Compute the cost of putting the fence as follows:

Cost of putting the fence = Circumference of the big circle × Cost of fencing

                                          [tex]=2\pi R\times \$8.25\\\\=2\times \frac{22}{7}\times \frac{37}{2}\times \$8.25\\\\=\$959.36[/tex]

The cost of putting the fence is $959.36.

The total cost of painting the deck and add fencing is:

Total Cost = Cost of painting the deck + Cost of putting the fence

                 = $427.43 + $959.36

                 = 1386.79

Thus, the total cost of painting the deck and add fencing is $1,386.79.

Northlake high scores to lunch. Soon can eat their lunch in the cafeteria or on an outside patio about 35% of students who have first lunch eat outside compare this with a percenta

Answers

Answer:

The proportion of second lunch students who eat outside is more than that for the first lunch students.

Step-by-step explanation:

The complete question is:

Points Northlake High School has two lunch periods. Students can eat their lunch in the cafeteria or on an outside patio. About 35% of students who have first lunch eat outside. Compare this with the percentage of second-lunch students who eat outside.

                            Eat Outside         Eat Inside          Total

First Lunch                 0.19                    0.35               0.54

Second Lunch           0.22                   0.24               0.46

Total                           0.41                    0.59               1.00

Solution:

The conditional probability of an event B given that another event A has already occurred is:

[tex]P(B|A)=\frac{P(A\cap B)}{P(A)}[/tex]

The probability of students who have second lunch (S) and eat outside (O) is:

P (S ∩ O) = 0.22

The probability of students who have second lunch (S) is:

P (S) = 0.41

Compute the proportion of student who eats outside given they have second lunch as follows:

[tex]P(O|S)=\frac{P(S\cap O)}{P(S)}[/tex]

            [tex]=\frac{0.22}{0.41}\\\\=0.536583\\\\\approx 0.54[/tex]

The proportion of second lunch students who eat outside is more than that for the first lunch students.

Mjhs is refinishing a basketball court and decided to paint everything shown below blue. How many square feet will be painted blue?

Answers

Answer:

Mjhs needs 189.25 square feet of blue paint, approximately.

Step-by-step explanation:

As you can observe in the image attached, the basketball court is a composite figure formed by a rectangle and half of a circle.

The rectangle has dimensions of 10 feet by 15 feet. The circle has a diameter of 10 feet.

The expression of this composite area would be

[tex]A= w \times l + \frac{\pi (\frac{l}{2} )^{2} }{2}[/tex]

Where [tex]w = 15 \ ft[/tex] and [tex]l = 10 \ ft[/tex]. Replacing these values, we have

[tex]A= 15 \times 10 + \frac{3.14 (\frac{10}{2} )^{2} }{2}\\ A=150 + \frac{3.14 \times 25}{2}=150+39.25 \\ A \approx 189.25 \ ft^{2}[/tex]

Therefore, Mjhs needs 189.25 square feet of blue paint, approximately.

Find a 99​% confidence interval for the mean duration of​ imprisonment, mu​, if a sample of the size determined in part​ (c) has a mean of 36.5 months.

Answers

Answer:

a) [tex] E = \frac{49.2-17.6}{2}= 15.8[/tex]

b) For this case we have 95% of confidence that the true mean would be between [tex]\pm 15.8[/tex] units respect the true mean.

c) [tex]n=(\frac{2.58(45)}{11})^2 =111.39 \approx 112[/tex]

So the answer for this case would be n=112

d) [tex]36.5-2.58\frac{45}{\sqrt{112}}=25.53[/tex]    

[tex]36.5+2.58\frac{45}{\sqrt{112}}=47.47[/tex]

Step-by-step explanation:

Part a

For this case we know that the cinfidence interval for the true mean is given by:

[tex] \bar X \pm E[/tex]

Where E represent the margin of error. For this case we have the confidence interval at 95% of confidence and we can estimate the margin of error like this:

[tex] E = \frac{49.2-17.6}{2}= 15.8[/tex]

Part b

For this case we have 95% of confidence that the true mean would be between [tex]\pm 15.8[/tex] units respect the true mean.

Part c

The margin of error is given by this formula:

[tex] ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}[/tex]    (a)

And on this case we have that ME =11 and we are interested in order to find the value of n, if we solve n from equation (a) we got:

[tex]n=(\frac{z_{\alpha/2} \sigma}{ME})^2[/tex]   (b)

The critical value for 99% of confidence interval now can be founded using the normal distribution. The critical value would be [tex]z_{\alpha/2}=2.58[/tex], replacing into formula (b) we got:

[tex]n=(\frac{2.58(45)}{11})^2 =111.39 \approx 112[/tex]

So the answer for this case would be n=112

Part d

The confidence interval for the mean is given by the following formula:

[tex]\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}}[/tex]   (1)

Replcaing the info given we got:

[tex]36.5-2.58\frac{45}{\sqrt{112}}=25.53[/tex]    

[tex]36.5+2.58\frac{45}{\sqrt{112}}=47.47[/tex]
