18x+12x = 180

30x = 180

x = 180/30

x = 6

The experimental probability of rolling a 1 or a 2 is 0.2.

Hence, Option A is correct.

We know that,

The experimental probability of an event is defined as the number of times the event occurred divided by the total number of trials.

In this case,

The event is rolling a 1 or a 3,

Which occurred ⇒  3 + 1

                           = 4 times.

Given that there are total number of trials = 20.

Therefore,

The experimental probability of rolling a 1 or a 3 = 4/20,

                                                                                = 1/5

                                                                                 = 0.2

Hence, the required probability is 0.2.

A point that represents how Dre can spend money on spray paint is plotted on the proportional relationship graphed at the end of the answer.

The money spent after sales tax is obtained multiplying the money spent before sales tax by a constant, hence a proportional relationship models the situation.

The general format of a proportional relationship is given as follows:

y = kx.

In which k is the constant of proportionality.

In this problem, the sales tax rate is of 10%, meaning that the total amount paid is composed as follows:

Considering x as the cost before sales tax, the equation is given as follows:

y = x + 0.1x

y = 1.1x.

Meaning that one point is given as follows:

(5,5.5).

Meaning that when the cost before sales tax is of $5, the cost including sales tax is of $5.5.

Assume the sales price is $15 per unit, variable cost is $6 per unit, and fixed cost is $5,000. If the variable cost decreases to $3 per unit. The number of units is 250 units.

Using this formula to find the units sold

Number of units = [Fixed cost / ( Sales - variable cost)]  - [Fixed cost / ( Sales - decrease in variable cost)

Let plug in the formula

Number of units = [$9,000 / ($15- $6)] - ($9,000 / ($15-$3)

Number of units = ($9,000 /$9) - ($9,000 / $12)

Number of units = 1,000- 750

Number of units = 250 units

Note:

(Fixed cost + target profit = $5,000+$4,000 = $9,000)

Therefore 250 units was sold.

The expression "five to the three-fourths power raised to the two-thirds power" can be rewritten as a radical expression.

First, let's calculate the exponentiation inside the parentheses:

(5^(3/4))^2/3

To simplify this, we can use the property of exponentiation that states raising a power to another power involves multiplying the exponents:

5^((3/4) * (2/3))

When multiplying fractions, we multiply the numerators and denominators separately:

5^((3 * 2)/(4 * 3))

Simplifying further:

5^(6/12)

The numerator and denominator of the exponent can be divided by 6, which results in:

5^(1/2)

Now, let's express this in radical form. Since the exponent 1/2 represents the square root, we can write it as:

√5

Therefore, the expression "five to the three-fourths power raised to the two-thirds power" simplifies to the radical expression √5.

The distance the puck traveled from the wall to Pedro is determined as √(ab).

Let's call the distance from Meg to the wall "a" and the distance from Pedro to the wall "b".

Let's also call the distance the puck travels from the wall to Pedro "x".

Since the two triangles are similar, we can set up a proportion:

a / x = x / b

We can cross-multiply to get:

x² = ab

And then take the square root of both sides to get:

x = √(ab)

12 pieces can the sausage be cut if each piece is to be two-thirds of an inch.

Multiplication is the opposite of division. If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group. Creating equal groups or determining how many people are in each group after a fair distribution is the basic objective of division. In mathematics, division is the process of dividing a number into equal parts and calculating the maximum number of equal parts that may be formed. For instance, dividing 15 by 3 results in the division of 15 into 3 groups of 5 each.

The Sargan and Hansen tests are statistical tests used to check the validity of instruments in the context of instrumental variables (IV) regression. These tests help determine whether the instruments are uncorrelated with the error term and correctly excluded from the estimated equation. When to use each test:

1. Sargan Test: You can use the Sargan test when performing Two-Stage Least Squares (2SLS) regression with multiple instruments. The test is applicable for both over-identified and exactly identified models, but it is not robust to heteroskedasticity or autocorrelation.

2. Hansen Test: Also known as the J-test, the Hansen test is used when performing Generalized Method of Moments (GMM) regression. It is applicable for over-identified models and is robust to both heteroskedasticity and autocorrelation, making it a more reliable choice in those situations.

In summary, use the Sargan test when you're working with 2SLS regression, and choose the Hansen test when dealing with GMM regression or when you need robustness against heteroskedasticity and autocorrelation.

Sabemos que:

\(MH(x, y) = \frac{2xy}{x+y}\)

y tenemos que:

\(MH (a,4) = \frac{2*a*4}{a+4} = \frac{8*a}{a+4} = 6\)

Con esto podemos encontrar el valor de a:

8*a/(a+ 4) = 6

8*a = 6*(a + 4) = 6*a + 24

8a - 6a = 24

2a = 24

a = 24/2 = 12.

Tambien sabemos que:

\(MH(8,b) = \frac{2*8*b}{8+b} =\frac{16*b}{8+b} = 12\)

Y de ahí podemos despejar b:

(16*b)/(b + 8) = 12

16*b = 12*(b + 8) = 12b + 96

16b - 12b = 96

4b = 96

b = 96/4 = 24

Entonces tenemos a = 12 y b = 24, y el MH de a y b es:

MH(12,24) = 2*12*24/(12 + 24) = 24*24/36 = 16

We can see that the marginal product of labor column for each worker can be filled with the calculated values of the marginal product of labor (MPL).

In the given problem, we are provided with the output data of a pizza-making firm. We have to fill in the blanks to complete the marginal product of labor column for each worker.

Let us first define Marginal Product of Labor:

Marginal product of labor (MPL) is the additional output produced by an extra unit of labor added, keeping all other inputs constant. It is calculated as the change in total output divided by the change in labor.

Let us now calculate the marginal product of labor (MPL) of the given workers: We are given the following data:

Labor Output Marginal Product of Labor (Number of Workers) (Pizzas) (Pizzas) \(0 0 - 1 50 50 2 90 40 3 120 30 4 140 20 5 150 10\)

To calculate the marginal product of labor, we need to calculate the additional output produced by an extra unit of labor added. So, we can calculate the marginal product of labor for each worker by subtracting the output of the previous worker from the current worker's output.

Therefore, the marginal product of labor for each worker is as follows:

1st worker = 50 - 0 = 50 pizzas 2nd worker = 90 - 50 = 40 pizzas 3rd worker = 120 - 90 = 30 pizzas 4th worker = 140 - 120 = 20 pizzas 5th worker = 150 - 140 = 10 pizzas

Thus, we can see that the marginal product of labor column for each worker can be filled with the calculated values of the marginal product of labor (MPL).

The correct option is;

f(x) = 64(three-fourths)Superscript x minus 1

Step-by-step explanation:

The first peak height that the bouncing toy reaches = 64 inches

The second peak height that the bouncing toy reaches = 48 inches

The third peak height that the bouncing toy reaches = 36 inches

Therefore, given that the sequence has a common ratio, r = 48/64 = 36/48 = 3/4

The first term of the sequence, a = The first peak height reached = 64

The xth term of the geometric sequence with general form, xth term = ar⁽ˣ⁻¹⁾

The xth term of the geometric sequence, f(x), is therefore, given as follows;

The rule for the given set of data is y = 3x - 1.

The relationship between dependent and independent variables, expressed as an equation, is referred to as a function rule. In order to calculate the value of the dependent variable, say y, in terms of the independent variable, say x, one must follow a specific function rule.

A function rule can be defined as the procedure that transforms an input value into an output in plain English.

Lets put two of the points in slope formula

y - y₁ = m(x - x₁)

29 - (-13) = m(10 - ( -4))

42 = m14

m = 42/14

m = 3

Now lets make the equation

y - 29 = m(x - 10)

y = 3x - 30 + 29

y = 3x - 1

Thus, the rule for the given set of data is y = 3x - 1.

In linear equations, 64% of samples have nitrogen levels and phosphorus levels that are low.

What is linear equations?

P(low nitrogen) = 46% = 0.46

P(low phosphorus) = 28% = 0.28

P(low nitrogen and low phosphorus) = 10% = 0.10

P(low nitrogen or low phosphorus) = P(low nitrogen) + P(low phosphorus) - P(low nitrogen and low phosphorus)

= 0.46 + 0.28 - 0.10

= 0.64 = 64%

Hence , 64% of samples have nitrogen levels and phosphorus levels that are low.
