（This should be right but if its not please let me know）

Answer:

Step-by-step explanation

Step #1

3.50-2.87  will equal 0.63

Step #2

put 0.63 over 3.50 times that by 100 and you 63 and 350 so you divide that and get 0.18 which equals 18% your welcome loves

Answer:

So, the correct answer is (30.104, 32.896).

Step-by-step explanation:

To find the 95% confidence interval for the mean number of pounds of trash per person per week, we can use the following formula:

CI = X + Zα/2 * (σ/√n)

σ = population standard deviation = 7.8 pounds

n = sample size = 120

Plugging in the values, we get:

CI = 31.5 ± 1.96 \times(7.8/√120)

CI = 31.5 ± 1.96 \times 0.711

CI = 31.5 ± 1.39

Therefore, the 95% confidence interval for the mean number of pounds of trash per person per week is (30.11, 32.89).

So, the correct answer is (30.104, 32.896).

Given the following information: Five years ago, someone used her $40,000 saving to make a down payment for a townhouse in RTP. The house is a three-bedroom townhouse and sold for $200,000 when she bought it. After paying down payment, she financed the house by borrowing a 30-year mortgage.

Mortgage interest rate is 4.25%. Right after closing, she rent out the house for $1,800 per month. In addition to mortgage payment and rent revenue, she listed the following information so as to figure out investment return: 1. HOA fee is $75 per month and due at end of each year 2. Property tax and insurance together are 3% of house value 3. She has to pay 10% of rent revenue for an agent who manages her renting regularly 4. Her personal income tax rate is 20%. While rent revenue is taxable, the mortgage interest is tax deductible. She has to make the mortgage amortization table to figure out how much interest she paid each year 5. In the last five years, the market value of the house has increased by 4.8% per year 6.

Answer:

-3x^2+5x+12x-20

Combine like terms

-3x^2+17x-20

That is your answer

Step-by-step explanation:

Brainliest please!

Answer:

-3x²+17x-20

Step-by-step explanation:

First, multiply 3x by -x:

\(3x\times-x=-3x^{2}\)

Next, multiply 3x by 4

\(3x\times4=12x\)

Next, multiply -5 by -x

\(-5\times-x=5x\)

Then, multiply -5 by 4

\(-5\times4=-20\)

This gets you \(-3x^{2} +12x+5x-20\).

Lastly, simplify the equation by mixing 12x+5x, to get your answer:

-3x²+17x-20

The integral of 37/(\(x(lnx)^p\)) converges for p > 1, as the denominator becomes increasingly smaller as x approaches infinity.

The integral of the function \(37/(x(lnx)^p)\) can be calculated to determine whether it converges or diverges. The integral converges if the limit of the integral is finite. This means that the integral can be defined for any real value of x, from 0 to infinity. The value of p must be greater than 1 in order for the integral to converge smaller as x approaches infinity .This is due to the fact that the denominator of the function,\(x(lnx)^p\), will become increasingly smaller as x approaches infinity. Therefore, the integral of the function \(37/(x(lnx)^p)\)converges for values of p greater than 1.

40% of Damien’s marbles are 6/5 or 1.2.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Damien has three marbles.

40% of Damien’s marbles are blue.

That means,

40% of 3 blue marbles.

So, using the percentage formula,

40% of 3,

= 40 x 3/100

= 120/100

= 12/10

= 6/5

= 1.2

The rotation matrices for the given rotations are as follows:

Rotation of 90° about the X-axis: [[1, 0, 0], [0, 0, -1], [0, 1, 0]]

Rotation of 90° about the Y-axis: [[0, 0, 1], [0, 1, 0], [-1, 0, 0]]

Rotation of 45° about the Z-axis: [[0.707, -0.707, 0], [0.707, 0.707, 0], [0, 0, 1]]

To determine the rotation matrices, we use the standard formulas for 3D rotations. Each rotation is specified by an angle of rotation and the axis of rotation.

For a rotation of θ degrees about the X-axis, the rotation matrix is given by: [[1, 0, 0], [0, cos(θ), -sin(θ)], [0, sin(θ), cos(θ)]]

For a rotation of θ degrees about the Y-axis, the rotation matrix is: [[cos(θ), 0, sin(θ)], [0, 1, 0], [-sin(θ), 0, cos(θ)]]

For a rotation of θ degrees about the Z-axis, the rotation matrix is: [[cos(θ), -sin(θ), 0], [sin(θ), cos(θ), 0], [0, 0, 1]]

Substituting the respective angles into these formulas, we obtain the rotation matrices as stated in the direct answer.

The rotation matrix for a rotation of 90° about the X-axis is [[1, 0, 0], [0, 0, -1], [0, 1, 0]]. The rotation matrix for a rotation of 90° about the Y-axis is [[0, 0, 1], [0, 1, 0], [-1, 0, 0]]. The rotation matrix for a rotation of 45° about the Z-axis is [[0.707, -0.707, 0], [0.707, 0.707, 0], [0, 0, 1]].

Answer:

\(y=-\frac{1}{4} x-6\)

Step-by-step explanation:

The slope-intercept form is \(y=mx+c\), where m is the slope of the line and c is where the line crosses the \(y\)-axis.

To calculate \(m\) we can use the formula \(m = \frac{dy}{dx}\) where \(dy\) is the difference in \(y\) between two points and \(dx\) is the difference between \(x\).

Information we can get from the graph given: \(c=-6\). Since \(c\) is the point at which the line crosses the \(y\)-axis.

To find \(m\) let's get two points from the graph.

Point 1: \((4,-7)\)

Point 2: \((8,-8)\)

Now use the equation \(m = \frac{dy}{dx}\).

\(m = \frac{-7 - (-8)}{4-8} = -\frac{1}{4}\).

Now we have \(m\) and \(c\), let's put them back into the general equation.

\(y=-\frac{1}{4} x-6\)

In the Subgame Perfect Equilibrium of a Stackelberg model, firm 1 chooses a number, and firm 2 chooses a function. Therefore, option (d) is the correct answer.

The Subgame Perfect Equilibrium (SPE) is a solution concept in game theory that analyzes strategic decision-making in sequential games. In a Stackelberg model, firm 1 acts as the leader and sets its output level first, followed by firm 2 as the follower, who observes firm 1's output before making its decision.

In the Subgame Perfect Equilibrium of this model, firm 1 chooses a number (output level) while firm 2 chooses a function (strategy). This implies that firm 1's decision is made independently as a quantity, and firm 2, observing firm 1's choice, formulates its strategy based on that information.

Therefore, option (d) is the correct answer: Firm 1 chooses a number, and firm 2 chooses a function in the Subgame Perfect Equilibrium of a Stackelberg model.

A vector parallel to the line of intersection of the two planes 2y - 2x + z = -3 and 3z - 5x = 3 is u = (3, 1, -2).

To find the vector parallel to the line of intersection of the two planes 2y - 2x + z = -3 and 3z - 5x = 3, first use the two equations to find the parametric form of the line of intersection.

This can be done by solving one of the equations for one of the variables, such as by solving the first equation for z, resulting in z = 2x + 2y - 3. Substitute this expression into the second equation, 3(2x + 2y - 3) - 5x = 3, to get 6x + 6y - 9 = 5x.

Solve for x to get x = 6y - 9, and substitute this into the first equation, 2y - 2(6y - 9) + z = -3, to get z = -12y + 21.

Therefore, the parametric form of the line of intersection is x = 6y - 9, y = y, z = -12y + 21. Since this line is parallel to a vector, take a nonzero value of y, such as y = 1, to get the vector u = (3, 1, -2).

The correct term for a sample obtained in such a way that every element in the population has an equal chance of being selected is a "random sample."

In a random sample, each member of the population has an equal probability of being chosen, providing a representative subset of the population. This sampling method helps to reduce bias and ensures that the sample is more likely to accurately reflect the characteristics of the entire population.

Random sampling is a fundamental principle in statistics and research, allowing for generalizations and inferences to be made about the population based on the characteristics observed in the sample. It is widely used in various fields, such as social sciences, market research, and opinion polls, to draw meaningful conclusions about a larger population.

In geometry if two shapes have same shape and sides. Congruency is applicable for angles and sides.

According to the given question JKLM is a parallelogram.

From the definition of parallelogram which opposite sides of a parallelogram are equal in length and parallel.

∴ JM is parallel to KL and ∠1 ≅ ∠2 by the corresponding angle theorem.(when two parallel lines are intersected by a transversal their corresponding angles are equal).
