As we know that the perimeter of a parallelogram is the sum of all the side lengths of it . Also we know that the opposite sides are equal in a parallelogram. Therefore, here the two other sides AD and DC would be "t" and "13m" respectively.

Now also we are given that the perimeter of the parallelogram is 54m . So we can create a equation to find out "t" as ,

[tex]:\sf\implies Perimeter = 13m + t + 13c

m + t\\[/tex]

Since the perimeter is 54m , therefore;

[tex]:\sf\implies 54m = 26m + 2t \\[/tex]

Subtract 26m on both the sides,

[tex]:\sf\implies 54m - 26m = 2t\\[/tex]

Simplify,

[tex]:\sf\implies 28m = 2t \\[/tex]

Divide both the sides by "2" ,

[tex]:\sf\implies t = \dfrac{28m}{2} \\[/tex]

Simplify,

[tex]:\sf\implies \pink{ t = 14m } \\[/tex]

Hence the value of t is 14m .

Jason is correct when he says that a graph of the relationship includes the point (63, 140).

A proportional relationship is a type of relationship between two quantities in which they maintain a constant ratio to each other. This means that if one quantity is multiplied by a certain factor, the other quantity will also be multiplied by the same factor.

The relationship is defined according to the equation presented as follows:

y = kx.

In which k is the constant of proportionality, representing the increase in the output variable y when the constant variable x is increased by one, which is also the constant ratio of the relationship.

From the table given at the end of the answer, when x = 54, y = 120, hence the constant is given as follows:

k = 120/54

k = 2.2222.

Hence the equation is:

y = 2.2222x.

When x = 63, the output of the function is given as follows:

y = 2.2222 x 63

y = 140.

Hence Jason is correct when he says that a graph of the relationship includes the point (63, 140), as when x = 63, the output of the function is of y = 140.

The table is given by the image presented at the end of the answer.

The approximate value of the maximum of the function is 2350. In terms of the problem scenario this means that the company will make a maximum daily profit of $2350.

Part A:

The y-intercept is the point where the graph intersects the y-axis, which is when x = 0. Therefore, we can find the y-intercept by substituting x = 0 into the equation:

P(0) = -[tex]6(0)^2[/tex] + 180(0) + 1000

P(0) = 1000

The approximate value of the y-intercept is 1000. In terms of the problem scenario, this means that when the company doesn't increase the price of the solar panels (x = 0), the daily profit is $1000.

Part B:

The x-intercept is the point where the graph intersects the x-axis, which is when P(x) = 0. Therefore, we can find the x-intercept by solving the equation:

-[tex]6x^2[/tex] + 180x + 1000 = 0

We can use the quadratic formula to solve for x:

x = (

where a = -6, b = 180, and c = 1000

x = (-180 ± sqrt([tex]180^2[/tex] - 4(-6)(1000))) / 2(-6)

x = (-180 ± sqrt(32400 + 24000)) / (-12)

x = (-180 ± sqrt(56400)) / (-12)

x ≈ 4.4 or x ≈ 29.4

The approximate value of the x-intercept is 4.4 (or 29.4). In terms of the problem scenario, this means that the company would need to increase the price of the solar panels by approximately $22 (or $147) in order to break even and not make a profit or loss for the day.

Part C:

The maximum of the function occurs at the vertex of the parabola, which is given by the formula:

x = -b / 2a

In this case, a = -6 and b = 180, so:

x = -180 / 2(-6) = 15

To find the maximum profit, we can substitute x = 15 into the equation:

P(15) = -[tex]6(15)^2[/tex] + 180(15) + 1000

P(15) = 2350

The approximate value of the maximum of the function is 2350. In terms of the problem scenario, this means that the company will make a maximum daily profit of $2350 when they increase the price of the solar panels by $75 (i.e., 15 increments of $5).

The probability of making a Type I error is represented by alpha (α), which is typically set to 0.05 in hypothesis testing. Therefore, if α = .05, the likelihood of making a Type I error is 5% at most.

What is hypothesis testing? Hypothesis testing, also known as statistical hypothesis testing, is a technique used to evaluate two hypotheses about a population using sample data. One hypothesis, known as the null hypothesis (H0), proposes that there is no significant difference between a population parameter and a sample parameter, whereas the other hypothesis, known as the alternative hypothesis (H1), suggests that there is a significant difference between a population parameter and a sample parameter.You might have made a Type I error, but the probability is only 5% at most is true if you complete a hypothesis test using α = .05, and based on the evidence from the sample, your decision is to reject the null hypothesis, but the treatment actually has no effect. In the given situation, if the treatment actually has no effect, you might have made a Type I error, but the probability is only 5% at most. When the null hypothesis is rejected when it should not be, a Type I error occurs.

The probability that the series lasts exactly five games is 2p raise to the power 4(1-p).

How to find probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain. The higher the probability, the more likely it is that the event will occur.

To find the probability that the series lasts exactly five games, we need to consider all possible ways in which a team can win four games in five games played.

One possible scenario is that team A wins the first four games and team B wins the fifth game. The probability of this happening is:

P(A wins the first four games and B wins the fifth game) = p⁴ * (1-p)

Another possible scenario is that team B wins the first game, team A wins the next four games. The probability of this happening is:

P(B wins the first game and A wins the next four games) = p⁴* (1-p)

Therefore, the probability that the series lasts exactly five games is the sum of these two probabilities:

P(series lasts exactly five games) = p⁴* (1-p) + p⁴ * (1-p)

Simplifying the expression, we get:

P(series lasts exactly five games) = 2p⁴(1-p)

Therefore, the probability that the series lasts exactly five games is 2p⁴(1-p).

A sample point refers to an option (c)  individual outcome of an experiment

In probability, a sample point is a specific outcome or event that can occur in an experiment or study. It represents a single instance or realization of the random process being studied. For example, if the experiment is flipping a coin, a sample point could be "heads" or "tails". The set of all possible sample points is called the sample space.

Sample points are important in probability theory because they help determine the probability of a particular event occurring. By calculating the number of sample points that satisfy a given condition, we can determine the likelihood of that condition being met, and make predictions about the behavior of random processes.

To implement the distributing principle to the phrase 7(2x+5) - 4(2x+5), we must first divide the 7 and 4 within the parenthesis to their respective terms:

7(2x+5) - 4(2x+5) = (72x + 75) - (42x + 45)

Within the parenthesis, each term is simplified:

= (14x + 35) - (8x + 20)

We may now reduce the phrase by grouping similar terms:

= 14x - 8x + 35 - 20

= 6x + 15

As a consequence, using the distributive property on 7(2x+5) - 4(2x+5) yields 6x + 15.

The average period of the trials that were conducted with an amplitude of 10 degrees is 1.694 seconds.

What is amplitude ?

In mathematics, amplitude refers to the maximum displacement or distance from the equilibrium position of a periodic function, such as a sine or cosine wave. In other words, if a periodic function oscillates back and forth between two extreme values, the amplitude is the maximum distance from the average value or midpoint of the oscillation to one of the extreme values.

To calculate the average period of the trials that were conducted with an amplitude of 10 degrees, we simply add up all the periods and divide by the total number of trials.

10 degrees: 1.66 s, 1.700 s, 1.71 s, 1.68 s, 1.72 s

Average period = (1.66 + 1.700 + 1.71 + 1.68 + 1.72) / 5 = 1.694 seconds

Therefore, the average period of the trials that were conducted with an amplitude of 10 degrees is 1.694 seconds.

For the number of miles driven, Company A will charge less than Company B if x<y, where x is the number of miles driven for Company A and y is the number of miles driven for Company B. Therefore, the inequality is x<y.

When comparing two companies for their charges for a specific service, it is necessary to obtain a basic understanding of the charges for each company. You can make use of the inequality operator to check when one company will charge less than the other company.

To use the inequality operator, you'll need to calculate the differences between the two companies for the specific mileage. Let's assume that the mileage is represented by "m" and that the charge for company A is "cA" and the charge for company B is "cB".

If the question only provides specific numerical values for these variables, you can substitute them into the inequality formula. If you're given algebraic expressions, you'll need to simplify them before substituting them into the inequality formula.

The inequality formula for comparing the charges is as follows: cA < cB.

To use this formula, substitute the expression for each variable.

For example: 4m + 20 < 3.5m + 35 Now, you'll need to simplify the inequality by performing algebraic operations on both sides of the inequality. Begin by subtracting 3.5m from both sides of the inequality: 0.5m + 20 < 35.

Next, subtract 20 from both sides of the inequality: 0.5m < 15 Finally, divide both sides of the inequality by 0.5: m < 30

Therefore, Company A will charge less than Company B for any mileage less than 30.

The perimeter of the letter "T" is 22 inches.

Since the letter "T" is formed by placing two rectangles next to each other, its perimeter is the sum of the perimeters of the two rectangles minus the shared side.

The shared side will be the width of the rectangles, which is 2 inches.

The lengths of the rectangles are 4 inches each.

Let's calculate the perimeter:

Perimeter of the top rectangle = 2 * (length + width) = 2 * (4 + 2) = 12 inches

Perimeter of the bottom rectangle = 2 * (length + width) = 2 * (4 + 2) = 12 inches

Now, subtract the shared side (width) once:

Shared side = 2 inches

Total perimeter = (Perimeter of top rectangle + Perimeter of bottom rectangle) - Shared side

Total perimeter = (12 + 12) - 2 = 22 inches

So, the perimeter of the letter "T" is 22 inches.

The total number of units produced in an 8-hour day is approximately 22.86 units.

There are different ways to approach this problem, but one possible method is to use the concept of cycle time and the total available production time to determine the number of units produced in a day.

An operation is performed on a batch of 100 units.

Setup time is 20 minutes and run time is 1 minute.

The total number of units produced in an 8-hour day is:

Step 1: Find the cycle time per unitThe cycle time per unit is the sum of the setup time and the run time:

Cycle time = setup time + run time = 20 minutes + 1 minute = 21 minutes.

Step 2: Find the total available production time in a day

One day has 24 hours, but 8 hours are not available for production due to breaks, maintenance, and other factors. Therefore, the total available production time is:

Total available production time = 8 hours × (60 minutes per hour) = 480 minutes.

Step 3: Calculate the number of units produced in a day

The number of units produced in a day is the total available production time divided by the cycle time per unit:

Units produced = total available production time ÷ cycle time= 480 minutes ÷ 21 minutes≈ 22.86 units (rounded to two decimal places)

Therefore, the total number of units produced in an 8-hour day is approximately 22.86 units.

This assumes that there is no variability in the process, and that all units are of good quality.

If there are any defects, rework, or other disruptions, the actual production may be lower.
