What is the surface area in square inches of direct angular prism formed by folding the net below.

a) The total amount that the Scotts ended up paying for the townhome (including the down payment and the monthly payments) is $445,144.80.

b) The total interest paid on the mortgage is $213,144.80.

The down payment is the advance payment made on a mortgage or loan to satisfy the lending concerning the borrower's financial capacity.

The down payment reduces the mortgage liability, including interest.

The cost of the townhome = $232,000

The down payment for the town home made by the Scotts = $48,000

The mortgage = $184,000 ($232,000 - $48,000)

Monthly payment = $1,103.18

The mortgage period = 360 months (30 years x 12)

The total payment on the mortgage over the mortgage period = $397,144.80 (1,103.18 x 360)

The total payment, including the down payment = $445,144.80 ($397,144.80 + $48,000)

The total interest paid = $213,144.80 ($445,144.80 - $232,000)

Answer:

830.53 in²

Step-by-step explanation:

Find the area of the full circle and divide it by 2:Use the circle area formula, A = r²Plug in 3.14 as pi, and plug in the radius:A = r²A = 3.14(23²)A = 1661.06Divide this by 2:1661.06 / 2= 830.53So, the area of one semicircle is 830.53 in²

Answer: The area of one semicircle is approximately 830.53 square inches.

Step-by-step explanation:

The area of a circle is given by the formula:

A = πr²

where A is the area of the circle and r is its radius.

The radius of the circle cut out of the piece of wood is about 23 inches. Therefore, its area is:

A = πr²

A = π(23)²

A = π(529)

A ≈ 1661.06 square inches

The carpenter cuts the circle into two semicircles. Therefore, the area of one semicircle is:

A/2 ≈ 830.53 square inches

Therefore, the area of one semicircle is approximately 830.53 square inches.

A secant of the circle is AD

A point of tangency is F

7. To find the radius, identify the diameter of the circle. For the diagram, it can be said that the diameter of the circle P is 4.

The radius then is 4/2 = 2.

The radius of circle q is 2/2 = 1

You could also use the formula

Answer: 6

Step-by-step explanation:

a) the   proportion of even numbers in the population is 2/3 or approximately 0.667.

b. Sample Proportions and Probability Distribution Table is attched.

c) c. The mean of the sampling distribution of the sample proportion of even numbers is approximately 0.3333.

d. The sample poportion is a biased estimator of the population proportion because   the  sample proportions do not target the proportion of even numbers in   the population.

a. The population consists of 2, 6, and 7. The proportion of even numbers in the population is 1/3 since only 6 is even.

b. We can find the proportion of even numbers in each sample as follows:

2,2:   2/2 = 1

2,6: 1/2 = 0.5

2,7: 1/2  = 0.5

6,2: 1/2 =   0.5

6,6:   2/2 = 1

6,7: 1/ 2 = 0.5

7, 2: 1/2 = 0.5

7,6: 1/2 = 0.5

 7,7: 0/2   =0

This means that

   0 ⇒     1/9

  0.5⇒    5/9

   1  ⇒    3/9 (or 1/3)

So the above is summarized onto the table attached.

C)  The mean of the sampling distribution    of the sample proportion of even numbers is the weighted average of the possible values of the sample proportion,

where the weights are the probabilities of each value. Hence,

(0 x 1/9) +   (0.5 x 6/9 ) + (1 x 2/  9)

Using the Law of Cosines, the angle between the lines PX and PY is found to be approximately 101.5°. Subtracting this angle from the bearing of Y from P (125°) and the bearing of X from P (35°) gives a bearing of approximately 54.5° from X to Y.

We can use the Law of Cosines to find the angle between the lines PX and PY, and then add this angle to the bearing of X from P to find the bearing of Y from X.

Let A be the angle between the lines PX and PY, and let C be the distance between X and Y. Then we have

C² = PX² + PY² - 2(PX)(PY)cos(A)

Substituting the given values, we get

950² = 420² + PY² - 2(420)(PY)cos(A)

Solving for cos(A), we get

cos(A) = (PY^2 - 950^2 - 420^2) / (-2)(420)(950)

cos(A) = -0.186

Since A is an acute angle, we can take the inverse cosine to find its measure

A = cos⁻¹ (-0.186)

A ≈ 101.5°

The bearing of X from P is 35°, so the bearing of Y from X is

125° - 35° - A ≈ 54.5°

Therefore, the bearing of Y from X is approximately 54.5 degrees to the nearest minute.

When the number of milligrams reaches 11, the drug is to be injected again. We need approximately 6.7 hours between injections.

The given function is D(h)=30[tex]e^{-0.35h[/tex], which gives the number of milligrams D(h) of the drug in the patient's bloodstream h hours after it is injected.

When the drug is injected again, the number of milligrams in the bloodstream will be 11. Therefore, we need to find the value of h that satisfies the equation:

11 = 30[tex]e^{-0.35h[/tex]

To solve for h, we can first divide both sides by 30:

11/30 = [tex]e^{-0.35h[/tex]

Next, we take the natural logarithm of both sides:

ln(11/30) = ln([tex]e^{-0.35h[/tex])

Using the property of logarithms that ln(eˣ) = x, we can simplify the right side:

ln(11/30) = -0.35h

Finally, we can solve for h by dividing both sides by -0.35 and multiplying by -1:

h = (-1/0.35)ln(11/30)

The test statistic is z₀ = 2.65 and the P-value is 0.004. The null hypothesis is rejected at the 5% level of significance, and we conclude that there is sufficient evidence to suggest that the true proportion is greater than 0.8.

To test the hypothesis using the P-value approach, we can follow these steps:

Check whether the sample size is large enough for the normal approximation to the binomial distribution. The requirements are satisfied if np₀ >= 10 and n(1-p₀) >= 10,

where p₀ is the hypothesized proportion under the null hypothesis. In this case, p₀ = 0.8, n = 125, so np₀ = 100 and n(1-p₀) = 25, both of which are greater than 10.

Set up the null and alternative hypotheses.

The null hypothesis is H₀: p = 0.8 (the true proportion is 0.8).

The alternative hypothesis is H₁: p > 0.8 (the true proportion is greater than 0.8).

Calculate the test statistic.

Under the null hypothesis, the test statistic follows a standard normal distribution.

The test statistic is calculated as:

z₀ = (x - np₀) / sqrt(np₀(1-p₀))

where x is the number of successes in the sample.

Plugging in the values, we get:

z₀ = (105 - 1250.8) / √(1250.8 x 0.2)

z₀ = 2.65

Calculate the P-value.

The P-value is the probability of observing a test statistic as extreme or more extreme than the one calculated from the sample, assuming the null hypothesis is true.

Since this is a right-tailed test (H₁: p > 0.8), we calculate the area to the right of the test statistic.

Using a standard normal table or calculator, we find that the area to the right of z₀= 2.65 is 0.004.

Therefore, the P-value is 0.004.

Make a decision and interpret the results.

Using a significance level of α = 0.05, we compare the P-value to α.

Since the P-value (0.004) is less than α (0.05), we reject the null hypothesis.

We conclude that there is sufficient evidence to suggest that the true proportion is greater than 0.8 at a 5% level of significance.

When an object turns 90 degrees around in a circle, it turns 1/4 of the way around in a circle. Therefore, the correct statement is: "It turns 1/4 of the way around in a circle."

To understand why an object turning 90 degrees around in a circle turns 1/4 of the way around in a circle, it's helpful to consider the relationship between angles and circles.

A circle is a geometric shape that is defined by a set of points that are equidistant from a center point.

The distance from the center point to any point on the circle is called the radius of the circle. The circumference of a circle is the distance around the circle, and it is equal to 2π times the radius.

A circle has a total angle of 360 degrees. When an object turns 90 degrees around in a circle, it covers only a quarter of the total angle.
