Given,An investment of $50,000 in property taxes and rental income received of $800 per month, annual taxes of $1,500 paid monthly for four years.

We need to calculate the Return on Investment (ROI).Let us begin with calculating the total amount of rental income received by multiplying the monthly rental income by 12 and then multiplying the resultant by 4, as it is for 4 years. Rental income received= 12 × 4 × 800 = $38,400

Now, let us calculate the total amount of taxes paid by multiplying the annual taxes by 4. Annual taxes = $1,500Total taxes paid

= 4 × $1,500

= $6,000Now, let us calculate the ROI. ROI

= (Total rental income received − Total expenses)/Total investment

= (38,400 − 6,000)/50,000

= 32,400/50,000

= 0.648 or 64.8%

The ROI for the investment is 64.8%. Hence, e. 4.25% is the correct option.

Answer:

$12,155.06

Step-by-step explanation:

Using the compound interest formula;

A= P(1+r)^n

P = $10,000

rate r = 5% = 0.05

Time r = 4years

Substitute

A = 10,000(1+0.05)^4

A = 10,000(1.05)^4

A = 10,000(1.21550)

A = 12,155.06

Hence the amount after 4 years will be $12,155.06

If a U.S. adult is selected at random, the probability that he or she has never spent any money gambling online is 95.

Gambling, the betting or staking of something of value, with consciousness of risk and hope of gain, on the outcome of a game, a contest, or an uncertain event whose result may be determined by chance or accident or have an unexpected result by reason of the bettor’s miscalculation.

Given that there was a 5 probability of U.S. adults admitted to having spent money gambling online.

We have to find the probability of a U.S. adult selected randomly that he or she has never spent any money gambling online.

We will assume the probability of the outcome which is known as  P(E) and the probability of the outcome which we need to know as , P(E) since both are the complement of each other. Then we will substitute the value of P(E) in the formula compliment of P(E)= 1-P(E)  so as to obtain compliment of P(E)

Given that there was a 5 probability of U.S. adults admitted to having spent money gambling online, therefore

        P(E) =5

        P(E)= 5/100

               =0.05

The probability of a U.S. adult selected randomly that he or she has never spent any money gambling online will be given as compliment of P(E) , such that

compliment of P(E)= 1-P(E)

                             =0.95

                            = 0.95/100

                            =95

There are 176,851 ways to assign the 100 pages to the four printers.

Since there are no restrictions on how many pages a printer can print, we can think of this problem as distributing 100 identical pages among 4 distinct printers. This is an example of a "balls and urns" problem, which can be solved using the stars and bars formula.

The stars and bars formula states that the number of ways to distribute k identical objects among n distinct containers is:

C(k+n-1, n-1)

where C represents the combination function. In this case, we have k = 100 identical pages and n = 4 distinct printers. Therefore, the number of ways to assign the pages to the printers is:

C(100+4-1, 4-1) = C(103, 3) = 176,851

So there are 176,851 ways to assign the 100 pages to the four printers.

This refers to the ratio between the scale of a given original object and a new object. It is its representation but of a different size (bigger or smaller). For example, if we have a rectangle of sides 2 cm and 4 cm, we can enlarge it by multiplying each side by a number, say 2.

Solving for the area and scale factor we have:

L= 5 units

W = 2 units

A = (5 x 2)

A = 10 square units.

A= (Scale factor of  L * W)*  L * W

= (2 x 2 x 5 x 2)

Answer:

9π - 9

Step-by-step explanation:

Depends on what the question stated was pi (π). The area of the circle is 9(3 squared) * π. the shaded area is the area of the circle - the area of the triangle. The area of the triangle is base * high / 2. If the diameter of the circle (6) is what we use as the base, then 3 would be the high, making the area 9. This means the shaded area would be 9π - 9.

Our standard linear slope equation is:

mx + b = y

We're told our slope is 1/2, so that's our m value.

When x = 0 our value is 5. If you need this visualized, then:

1/2 * 0 +b = 5

0 + b = 5

b = 5

So our equation looks like:

x/2 + 5 = y

a) The statement is true. All square, upper triangular matrices are diagonalizable.

b)  The statement is false. If a matrix is diagonalizable, then it is invertible.

a) A square matrix is diagonalizable if and only if it has n linearly

independent eigenvectors, where n is the size of the matrix. For an

upper triangular matrix, the eigenvalues are simply the diagonal entries.

Since the eigenvectors of an upper triangular matrix are the standard

basis vectors (1,0,...,0), (0,1,0,...,0), ..., (0,0,...,1), they are linearly

independent. Therefore, every square, upper triangular matrix is

diagonalizable.

b)A matrix A is invertible if and only if its determinant is nonzero: det(A) ≠

0. A matrix is diagonalizable if and only if it has n linearly independent

eigenvectors, where n is the size of the matrix.

It is true that every invertible matrix is diagonalizable. However, the

converse is not true. For example, the zero matrix is diagonalizable (with

any set of linearly independent eigenvectors), but it is not invertible.

Similarly, the matrix with all entries equal to 1 is diagonalizable (with any set of linearly independent eigenvectors), but it is not invertible either.

The x-coordinate is 4: This tells us that the point lies on the vertical line that passes through x = 4 on the coordinate plane.

The y-coordinate is 122: This tells us that the point also lies on the horizontal line that passes through y = 122 on the coordinate plane.

Combining these two pieces of information, we can conclude that the point (4, 122) represents the intersection of the vertical line x = 4 and the horizontal line y = 122 on the coordinate plane.

In other words, if we were to plot this point on the coordinate plane, it would be 4 units to the right of the origin and 122 units above the origin.
