Given that the city officials estimate that 46 percent of all city residents are in favor of building a new city park. A random sample of 150 city residents will be selected and assume that 51 percent of the sample are in favor of building a new city park. The sampling distribution of the sample proportion for samples of size 150 is approximately normal, and the mean is 0.46. The statement that describes the distribution of the sample proportion for samples of size 150 is "The distribution is approximately normal, and the mean is 0.46."

Sample size n = 150

Sample proportion = 51% = 0.51

The distribution of the sample proportion of all possible samples of size n (n = 150) is called the sampling distribution of the sample proportion.

The central limit theorem (CLT) states that the sampling distribution of the sample proportion will be approximately normal if the sample size is large enough. The sample size is large enough if

np ≥ 10 and n(1 - p) ≥ 10.

Here p is the population proportion.In the given problem, the population proportion is not known. But the sample size is 150, which is large enough to apply CLT.The mean of the sampling distribution of the sample proportion is the same as the population proportion.

Given that the city officials estimate that 46 percent of all city residents are in favor of building a new city park.

Hence, the mean of the sampling distribution of the sample proportion is 0.46.

At a discount rate of 20%, the present value of your aunt’s offer of $22,000 in 17 years is approximately $190.46.


To calculate the present value of your aunt’s offer, we use the discount rate of 20%. The formula for present value is PV = FV / (1 + r)^n, where PV is the present value, FV is the future value, r is the discount rate, and n is the number of periods. Plugging in the values, we have PV = $22,000 / (1 + 0.20)^17, which gives us approximately $190.46.

For the investment scenarios, we use the compound interest formula: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount (initial investment), r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years. Plugging in the given values for each case, we calculate the final amounts.
a. A = $12,500(1 + 0.07/1)^(1*8) ≈ $19,956.77.
b. A = $12,500(1 + 0.10/1)^(1*17) ≈ $46,426.32.
c. A = $12,500(1 + 0.12/2)^(2*20) ≈ $73,785.59.
Therefore, if you invest $12,500 today, you will have approximately $19,956.77 in 8 years at 7%, $46,426.32 in 17 years at 10%, and $73,785.59 in 20 years at 12% compounded semiannually.

In a square, the length of its sides are equal, and the diagonal of a square is equal to the length of its sides times the √2.

A square is a type of rectangle that has four equal sides and four equal angles of 90 degrees.

Let's start by labeling the vertices of the square ABCD. We can call the bottom left vertex "A", the top left vertex "B", the top right vertex "C", and the bottom right vertex "D". Since this is a square, we know that AB and DC are both equal to the length of the sides of the square. So, we can write:

AB = DC = x

In this case, we can break the square into two 45-45-90 triangles and use the Pythagorean theorem to find the length of the diagonal. In a 45-45-90 triangle, the ratio of the length of the shorter side to the length of the hypotenuse is 1:√2. So, the length of AC can be found as follows:

AC = BD = x * √2

Now, we can use the Pythagorean theorem again to find the length of y, which is the distance from point A to point C. We can form a right triangle with AC as the hypotenuse and x and y as the other two sides. Using the Pythagorean theorem, we can write:

x² + y² = (x * √2)²

Expanding and simplifying this equation, we find:

x² + y² = 2x²

So,

y² = x²

And,

y = x

Therefore, since x and y are equal, we can write:

x = y = AB = DC

So, the measure of x, y, AB, and DC is equal to the length of the sides of the square ABCD.

Answer:

\(\displaystyle c = \frac{20}{3}\)

Step-by-step explanation:

According to Rolle's Theorem, if f(a) = f(b) in an interval [a, b], then there must exist at least one c within (a, b) such that f'(c) = 0.

We are given that g(5) = g(8) = -9. Then according to Rolle's Theorem, there must be a c in (5, 8) such that g'(c) = 0.

So, differentiate the function. We can take the derivative of both sides with respect to x:

\(\displaystyle g'(x) = \frac{d}{dx}\left[ -7x^3 +91x^2 -280x - 9\right]\)

Differentiate:

\(g'(x) = -21x^2+182x-280\)

Let g'(x) = 0:

\(0 = -21x^2+182x-280\)

Solve for x. First, divide everything by negative seven:

\(0=3x^2-26x+40\)

Factor:

Zero Product Property:

\(x-2=0 \text{ or } 3x-20=0\)

Solve for each case. Hence:

\(\displaystyle x=2 \text{ or } x = \frac{20}{3}\)

Since the first solution is not within our interval, we can ignore it.

Therefore:

\(\displaystyle c = \frac{20}{3}\)

Total number of functions from A to B: 16807. Number of injective (one-to-one) functions from A to B: 2520 and number of functions from A to B with (1) = 14 and (2) = 2: 20. Number of functions from A to B with (3) = 6 and (4) ≠ 8: 30.

1. To find the total number of functions from A to B, we need to determine the number of possible mappings for each element in A. Since there are 5 elements in A and 7 elements in B, each element in A has 7 choices of elements in B to map to. Therefore, the total number of functions from A to B is 7^5 = 16807.

2. To count the number of injective (one-to-one) functions, we need to ensure that no two distinct elements in A are mapped to the same element in B. Since A has 5 elements and B has 7 elements, the first element in A has 7 choices, the second element has 6 choices (excluding the element already chosen for the first), the third element has 5 choices, the fourth has 4 choices, and the fifth has 3 choices. Therefore, the number of injective functions from A to B is 7 * 6 * 5 * 4 * 3 = 2520.

3. For (1) = 14, we need to assign the element 14 in B to one of the elements in A. There are 5 choices for this assignment. For (2) = 2, we need to assign the element 2 in B to one of the remaining elements in A. There are 4 choices for this assignment. Therefore, the number of functions from A to B with (1) = 14 and (2) = 2 is 5 * 4 = 20.

4. For (3) = 6, we need to assign the element 6 in B to one of the elements in A. There are 5 choices for this assignment. For (4) ≠ 8, we need to assign any element in B except 8 to one of the remaining elements in A. There are 6 choices for this assignment. Therefore, the number of functions from A to B with (3) = 6 and (4) ≠ 8 is 5 * 6 = 30.

Answer:

Z=16

Step-by-step explanation:

just add 12 to both sides so you are left with only Z on one side

Answer:

=16

Step-by-step explanation:

Simplifying

z + -12 = 4

Reorder the terms:

-12 + z = 4

Solving

-12 + z = 4

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Add '12' to each side of the equation.

-12 + 12 + z = 4 + 12

Combine like terms: -12 + 12 = 0

0 + z = 4 + 12

z = 4 + 12

Combine like terms: 4 + 12 = 16

z = 16

Simplifying

z = 16

The estimated monthly payment for Brian's home loan would $1413.52.

To calculate the best estimate of the monthly payment for Brian's home loan, we can use the formula for calculating a fixed-rate mortgage payment.

The formula for the monthly payment of a fixed-rate mortgage is:

M = P * (r * (1+r)^n) / ((1+r)^n - 1),

where M is the monthly payment, P is the principal amount (loan amount minus down payment), r is the monthly interest rate, and n is the number of monthly payments.

In this case, Brian's principal amount is $220,000 - $22,000 = $198,000 (loan amount minus down payment). The monthly interest rate is 3.5% / 12 = 0.0029 (converted from annual interest rate to monthly rate), and the number of monthly payments is 180.

Plugging in these values into the formula, we get:

M = $198,000 * (0.0029 * (1+0.0029)^180) / ((1+0.0029)^180 - 1).

M = $198,000 * (0.0029 * (1+0.0029)^180) / ((1+0.0029)^180 - 1)

M = $1413.52

Evaluating this expression gives us the best estimate of the monthly payment. However, the calculation involves complex mathematical operations, and it is recommended to use a financial calculator or spreadsheet software to obtain an accurate estimate.

Note: It's important to consult with a financial advisor or a mortgage professional to get precise and personalized information about mortgage terms, interest rates, and monthly payments based on individual circumstances and loan options available.

\(x=1\)

Step-by-step explanation:

\(\sqrt{x-1} =2-\sqrt{x+3}\)

Square both sides.

\(\left(\sqrt{x-1}\right)^2=\left(2-\sqrt{x+3}\right)^2\)

\(x-1=x+7-4\sqrt{x+3}\)

Subtract x on both sides.

\(x-1-x=x+7-4\sqrt{x+3}-x\)

\(-1=-4\sqrt{x+3}+7\)

Subtract 7 on both sides.

\(-1-7=-4\sqrt{x+3}+7-7\)

\(-8=-4\sqrt{x+3}\)

Square both sides.

\(\left(-8\right)^2=\left(-4\sqrt{x+3}\right)^2\)

\(64=16x+48\)

Subtract 48 on both sides.

\(64-48=16x+48-48\)

\(16=16x\)

Divide both sides by 16.

\(\frac{16}{16} =\frac{16x}{16}\)

\(1=x\)

Switch sides.
