Scarcity principle: Resources are limited and choices must be made, b. Rational person: Makes decisions based on logical thinking and self-interest, c. Economic surplus: Net gain to society from producing and consuming a good, d. Marginal benefit: Additional benefit from consuming one more unit of a good or service.

A statement is a declarative sentence that expresses a fact, opinion, or idea. It is a sentence that makes a claim or assertion that can be true or false, and it can be either affirmative (positive) or negative. A statement can be a simple sentence, or it can be a complex sentence that includes multiple clauses

a. The scarcity principle is the economic principle that states that resources are limited and cannot satisfy all human wants and needs. This principle recognizes that we live in a world of limited resources, and therefore, we must make choices about how to allocate those resources to satisfy our wants and needs. For example, a farmer may have limited land and water resources to cultivate crops, and he must choose which crops to grow based on their profitability, water requirements, and market demand.

b. A rational person is an individual who uses logical thinking and makes decisions based on self-interest to achieve the best possible outcome. A rational person weighs the pros and cons of each option and selects the alternative that maximizes their satisfaction or utility. For example, a consumer may compare prices and quality of different brands before purchasing a product to get the best value for their money.

c. Economic surplus is the difference between the total value that consumers place on a good or service and the total cost of producing it. It represents the net gain to society from producing and consuming the good or service. For example, if a firm produces 100 units of a product at a total cost of $500 and sells them for a total of $700, then the economic surplus is $200.

d. Marginal benefit is the additional benefit that a person receives from consuming one more unit of a good or service. It is the change in total benefit divided by the change in the quantity consumed. For example, if a consumer derives 10 units of satisfaction from consuming the first slice of pizza and 8 units of satisfaction from consuming the second slice, then the marginal benefit of the second slice is 8-10=-2 units of satisfaction.

Therefore, a. Scarcity principle: Resources are limited and choices must be made, b. Rational person: Makes decisions based on logical thinking and self-interest, c. Economic surplus: Net gain to society from producing and consuming a good, d. Marginal benefit: Additional benefit from consuming one more unit of a good or service.

Answer:108 degrees

Step-by-step explanation:easy

Answer: The commission rate for the real estate agency is 7.5% of the sale price, which is:

0.075 x 343000 = $25,725

The agent's commission is 30% of the amount the agency gets, which is:

0.3 x 25725 = $7,717.50

Therefore, the real estate agency made $25,725 on the house and the agent earned a commission of $7,717.50.

Step-by-step explanation:

The area of the figure is approximately 163.8 square units, rounded to the nearest tenths place.

To find the area of this figure, we need to find the area of the parallelogram and the area of the semicircle, and then add them together.

The area of the parallelogram is given by the formula:

A = base x height

In this case, the base is 12 and the height is 9, so:

A_parallelogram = 12 x 9 = 108

The area of a semicircle is given by the formula:

[tex]A = (πr^2)/2[/tex]

where r is the radius of the semicircle.

The diameter of the semicircle is equal to the base of the parallelogram, which is 12. So, the radius of the semicircle is half of the diameter, or 6.

Substituting the values, we get:

A_semicircle = [tex](π x 6^2)/2 = 18π[/tex]

Adding the areas of the parallelogram and the semicircle, we get:

A = A_parallelogram + A_semicircle = 108 + 18π

Using a calculator to approximate π to the nearest tenths place, we get:

A ≈ 108 + 18 x 3.1 = 163.8

Therefore, the area of the figure is approximately 163.8 square units, rounded to the nearest tenths place.

Step-by-step explanation:

The product of eight and two is 8 x 2 = 16.

The product of three and four is 3 x 4 = 12.

So, the expression "the product of eight and two, minus the product of three and four" can be written as:

16 - 12 = 4

Therefore, the answer is 4.

The area of the ripple at t=2 is 32π square inches.

What is area ?

Area is the measure of the size of a two-dimensional surface enclosed by a closed boundary, such as a polygon or a circle. It is typically measured in square units such as square meters, square feet, or square inches.

The equation for the radius of the circular ripple is given by r(t) = √(15t+2). The equation for the area of a circle with radius r is A(r) = πr².

Therefore, the area of the ripple as a function of time is given by:

A(t) = π[r(t)]²

Substituting the expression for r(t), we get:

A(t) = π[(√(15t+2))²]

A(t) = π(15t+2)

A(t) = 15πt + 2π

To find the area of the ripple at t=2, we substitute t=2 into the expression for A(t):

A(2) = 15π(2) + 2π

A(2) = 30π + 2π

A(2) = 32π

Therefore, the area of the ripple at t=2 is 32π square inches.

the distance from the first plant to the last plant, ignoring the width of each plant stem, is 10.5 feet.

Why is it?

To find the distance from the first plant to the last plant, we need to add up the distances between each adjacent pair of plants. Since there are 8 plants, there are 7 pairs of adjacent plants, and each pair is separated by 1.5 feet.

So, the total distance from the first plant to the last plant is:

7 ×1.5 = 10.5 feet

Therefore, the distance from the first plant to the last plant, ignoring the width of each plant stem, is 10.5 feet.

In conclusion, the integer solutions of the given system of equations are [tex]$(x, y, z) = (1, 2, 0)$ and $(x, y, z) = (-1, 4, 0)$.[/tex]

An integer is a positive, negative, or zero-valued whole number. It is a number without a fractional or decimal component.

To find all integer solutions of the given system of equations:

[tex]x + y &= 3 \[/tex]

[tex]3xy - z^2 &= 9[/tex]

We can start by solving the first equation for one of the variables. Let's solve for y in terms of x:

[tex]x + y &= 3 \[/tex]

[tex]y &= 3 - x[/tex]

Now we substitute this expression for y into the second equation:

[tex]3xy - z^2 &= 9 \[/tex]

[tex]3x(3-x) - z^2 &= 9 \quad \text{Substituting } y = 3-x \[/tex]

[tex]9x - 3x^2 - z^2 &= 9 \[/tex]

[tex]3x^2 + z^2 &= 9x - 9 \[/tex]

[tex]3x^2 - 9x + z^2 &= -9 \quad \text{(1)}[/tex]

Now we will examine equation (1) for integer solutions.

To solve this problem, we can use the geometric distribution, which models the number of trials needed to obtain the first success in a sequence of independent trials.

Let X be the random variable representing the number of people a designer needs to ask until they find someone who agrees to be their model. Then X follows a geometric distribution with probability of success p = 0.38.

The probability that a designer needs to ask at most 3 people is the sum of the probabilities that they need to ask 1, 2, or 3 people:

P(X ≤ 3) = P(X = 1) + P(X = 2) + P(X = 3)

We can calculate these probabilities as follows:

P(X = 1) = p = 0.38

P(X = 2) = (1-p) × p = 0.62 × 0.38 = 0.2356

P(X = 3) = [tex](1-p)^{2}[/tex] × p = [tex](0.62)^{2}[/tex] × 0.38 = 0.1448

Therefore, the probability that a designer would have to ask at most 3 people to find someone that would agree to be their model is:

P(X ≤ 3) = P(X = 1) + P(X = 2) + P(X = 3) = 0.38 + 0.2356 + 0.1448 = 0.7604

Rounding this to four decimal places, we get 0.7604, which is closest to the answer option (D) 0.6156. However, none of the given answer options matches the calculated probability exactly.

Move the figure 2 units to the right  and  Move the figure 3 units downwards are the rules to translate any point on the red figure to the corresponding point on the orange figure, and vice versa

To describe the translation rule for the red figure to the orange figure, we need to determine how the red figure was moved to obtain the orange figure.

First, we can see that the orange figure is shifted to the right of the red figure. This means that the x-coordinate of every point on the orange figure is greater than the corresponding point on the red figure.

Second, we can see that the orange figure is shifted downwards from the red figure. This means that the y-coordinate of every point on the orange figure is less than the corresponding point on the red figure.

Therefore, the translation rule for the red figure to the orange figure is:

• Move the figure 2 units to the right (add 2 to the x-coordinate of every point), and

• Move the figure 3 units downwards (subtract 3 from the y-coordinate of every point).

We can use this rule to translate any point on the red figure to the corresponding point on the orange figure, and vice versa. This translation rule can be used in various applications such as computer graphics, engineering, and architecture, where precise translations of objects are necessary.
