Answer:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 69 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 69, so we can write it down as 100%=69.

4. We know, that x% equals 87 of the output value, so we can write it down as x%=87.

5. Now we have two simple equations:

1) 100%=69

2) x%=87

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=69/87

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 87 is what percent of 69

100%/x%=69/87

(100/x)*x=(69/87)*x       - we multiply both sides of the equation by x

100=0.79310344827586*x       - we divide both sides of the equation by (0.79310344827586) to get x

100/0.79310344827586=x

126.08695652174=x

x=126.08695652174

now we have:

87 is 126.08695652174% of 69

Answer:

The answer is $104.

Step-by-step explanation:

So take away the discount which is $50. That leaves $130. Then do the percentage decrease which is 130 minus 20%. The answer to that is $26. Her grandparents pay $104. (I'm really not sure of my answer though).

Her grandparents pay $104.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Kelsey's preschool tuition is $180 per week.

She receives a small discount for the honor roll, $50 per month.

Her grandparents help out and pay 20% of her tuition.

Kelsey's tuition fee after discount= 180- 50 = $130

and, Her grandparents pay = 130- 130 x 0.2 = 130- 26= $104

Hence, Her grandparents pay $104.

Use the illustration to solve. (If you have one.)

Step-by-step explanation:

If this shape is Irregular, than use the other angles to solve.

The marginal probability distributions can be computed by summing the probabilities along the rows and columns of the joint probability distribution.

To compute the marginal probability distributions, we need to sum the probabilities along the rows and columns of the joint probability distribution. Let's denote the joint probability distribution as P(X, Y), where X represents one variable and Y represents the other variable.

Step 1: Compute the marginal probability distribution of X.

To find the marginal probability distribution of X, we sum the probabilities across each row of the joint probability distribution, fixing the value of X and summing over all possible values of Y. This will give us the probabilities P(X) for each value of X.

Step 2: Compute the marginal probability distribution of Y.

Similarly, to find the marginal probability distribution of Y, we sum the probabilities across each column of the joint probability distribution, fixing the value of Y and summing over all possible values of X. This will give us the probabilities P(Y) for each value of Y.

Step 3: Interpret the marginal probability distributions.

The marginal probability distributions provide the probabilities of each variable independently, disregarding the other variable. They give us insights into the individual behavior of each variable without considering their joint occurrence.

The statement If a simple random sample is chosen with replacement, each individual has the same chance of selection on every draw is True.

If a simple random sample is chosen with replacement, it means that after each selection, the chosen individual is placed back into the population before the next selection is made. In this case, each individual in the population has the same chance of being selected for every draw.

The process of replacing the selected individual ensures that the selection probabilities remain constant throughout the sampling process. As a result, each individual has an equal probability of being chosen on each draw, making the statement true.

The correct matches are =

Proxy voting- Allowing someone else to vote one's shares

Board of Directors- the committee that hires, evaluates and monitors the senior managers of the firm

Preemptive right- The right to firstly buy any additional shares that the firm may issue before they are sold to the public

Straight-line voting- each candidate for the board of directors is elected by a majority vote

Cumulative voting- board seats are awarded in proportion to the votes received.

Definitions =

Proxy voting = Proxy voting is when a shareholder delegates their voting rights to another person or entity, known as a proxy, to vote on their behalf. This can be done for various reasons, such as when a shareholder is unable to attend a meeting or wants to entrust their voting decisions to someone else. It does not directly relate to board seats being awarded in proportion to the votes received.

Board of Directors = The Board of Directors is a group of individuals elected or appointed to represent the shareholders and oversee the management of a company. They are responsible for making major decisions, setting company policies, and appointing senior executives. Each candidate for the board of directors is typically elected by a majority vote of the shareholders.

Preemptive right = Preemptive right, also known as the right of first refusal, is a privilege granted to existing shareholders of a company. It allows them to have the first opportunity to purchase additional shares before they are offered to the public. This right helps protect the ownership interests of existing shareholders by giving them the chance to maintain their proportional ownership in the company.

Straight-line voting = Straight-line voting is not a commonly used term in corporate governance. However, based on the given options, it seems to be referring to a voting system where each shareholder is entitled to one vote per share they own. This is the standard method of voting in most corporate elections, where each shareholder's voting power is directly proportional to their shareholding.

Cumulative voting = Cumulative voting is a voting method that allows shareholders to pool their votes and allocate them as they see fit among the candidates for the board of directors. It gives minority shareholders the opportunity to concentrate their votes on fewer candidates and increase their chances of electing a representative to the board. This mechanism helps to ensure a more proportional representation of shareholders on the board.

The given statement "if set of difference scores with df = 8 has a mean of md = 3.5 then sample will produce repeated-measures t statistic of t = 1.75." is false because  it is not possible to determine t statistic.

In a repeated-measures t-test, the t statistic is calculated using the sample mean difference, the standard deviation of the sample mean difference, and the sample size. The formula for calculating the t statistic in a repeated-measures t-test is:

t = (md - μd) / (s / √n)

where md is the mean of the difference scores, μd is the population mean of the difference scores (typically assumed to be zero), s is the standard deviation of the difference scores, and n is the sample size.

In the given statement, we are provided with the mean of the difference scores (md = 3.5) and the variance (s² = 36), but we do not have the sample size (n). Therefore, we cannot calculate the t statistic using the given information.

 By multiplying matrices B and A, we obtain the product BA. Using BA, we can solve the system of equations y + 2z = 7, x - y = 3, and 2x + 3y + 4z = 17.the values of x, y, and z are -1, 2, and 1 respectively

To find the product BA, we multiply matrix B with matrix A. The resulting matrix will have the same number of rows as B and the same number of columns as A. The product BA will be used to solve the given system of equations.
The product BA can be computed by multiplying each row of matrix B by each column of matrix A and summing the results. The resulting matrix will be:
Now, we can use the product BA to solve the system of equations:
-10x - 10y + 6z = 7,
3x - 8y + 2z = 3,
-6x - 16y + 15z = 17.

1 -1 2
2 3 1
0 4 2
We can rewrite this system of equations as:
-10x - 10y + 6z = 7,
3x - 8y + 2z = 3,
-6x - 16y + 15z = 17.
By comparing the coefficients of x, y, and z in the system of equations with the entries in the matrix BA, we can determine the values of x, y, and z.
Solving the system of equations using matrix BA, we get:
x = -1,
y = 2,
z = 1.
Therefore, the values of x, y, and z are -1, 2, and 1 respectively.

The edge length of each cube, out of 27 similar cubes with a total volume of 3375 cm³, is 5 cm.

To find the edge length of one cube, we can divide the total volume of the cubes by the number of cubes.

Given:

Total volume of 27 cubes = 3375 cm³

We need to find the edge length of one cube.

Let's denote the edge length of one cube as "x."

The volume of a cube is calculated by taking the cube of its edge length:

Volume of one cube = x³

Since we have 27 cubes with the same edge length, the total volume is the sum of the volumes of all the cubes:

Total volume of 27 cubes = Volume of one cube × Number of cubes

3375 cm³ = x³ × 27

To solve for x, we divide both sides of the equation by 27:

3375 cm³ / 27 = x³

125 cm³ = x³

Taking the cube root of both sides gives us:

∛125 cm³ = ∛x³

5 cm = x

Therefore, the edge length of one cube is 5 cm.
