Answer:

x =  9(a+g)

Step-by-step explanation:

x/9 - g = a

Add g to each side

x/9 - g+g = a+g

x/9 = a+g

Multiply each side by 9

x/9 * 9 = 9(a+g)

x =  9(a+g)

If lines A, B and C shows proportional relationships, then the line A has a constant of proportionality between y and x is 5

Given the line A, B and C

The constant of proportionality is the ratio of the y coordinates to the x coordinate

k = y /x

Where k is the constant of proportionality

Consider the line A

One point on the line = (1, 5)

Constant of proportionality K = 5/1

= 5

Consider the line B

One point on the line = (3, 5)

Constant of proportionality k = 5/3

Consider the line C

One point on the line = (7, 5)

Constant of proportionality = 5/7

Therefore, the line A has the constant of proportionality of 5

1. The variability of the data tends to increase when using a repeated measures design. Disagree.

The repeated measures design involves collecting data from the same participants under different conditions or time points. This design reduces the variability caused by individual differences, as each participant serves as their own control. Therefore, the variability of the data tends to decrease rather than increase.

2. The cost of the study will tend to decrease when using a repeated measures design. Agree.

In a repeated measures design, data is collected from the same participants multiple times, reducing the need to recruit a large number of participants compared to independent group designs. This reduction in participant recruitment and associated costs can lead to a decrease in the overall cost of the study.

3. The number of participants will tend to increase when using a repeated measures design. Disagree.

A repeated measures design typically requires a smaller number of participants compared to independent group designs. In repeated measures, the same participants are measured multiple times, providing more statistical power and efficiency. Therefore, the number of participants needed may decrease compared to other designs.

4. The time it takes to run a study will tend to decrease when running a repeated measures design. Agree.

Since repeated measures involve collecting data from the same participants multiple times, the time required to run the study can be reduced. Researchers do not need to recruit and coordinate with new participants for each condition or time point, leading to a more efficient data collection process.

the optimal solution to maximize Z is x1 = 25 and x2 = 0, with Z = 3000.

To solve the given linear programming model graphically, we need to plot the feasible region and identify the corner points to find the optimal solution. Here's the step-by-step process:

1. Plot the constraints:

  - Plot the line x1 = 40 (vertical line at x1 = 40).

  - Plot the line x2 = 10 (horizontal line at x2 = 10).

  - Plot the line 20x1 + 10x2 = 500 (which can be rewritten as 2x1 + x2 = 50).

  - Shade the feasible region that satisfies all the constraints.

2. Identify the corner points:

  - Determine the coordinates of the corner points where the boundary lines intersect.

3. Evaluate the objective function:

  - Calculate the value of the objective function Z = 120x1 + 80x2 for each corner point.

4. Determine the optimal solution:

  - Select the corner point that maximizes the objective function Z.

Here's the graphical representation of the feasible region:

            0`

The corner points of the feasible region are:

A: (0, 0)

B: (0, 10)

C: (25, 0)

D: (20, 5)

Now, we evaluate the objective function Z = 120x1 + 80x2 for each corner point:

Z(A) = 120(0) + 80(0) = 0

Z(B) = 120(0) + 80(10) = 800

Z(C) = 120(25) + 80(0) = 3000

Z(D) = 120(20) + 80(5) = 2400

From the above calculations, we can see that the maximum value of Z occurs at point C: (25, 0).

Answer:

The correct answer is C: Y = -1/2x - 4.The slope of the given line is -1/2, so any line that is parallel to it will have the same slope. In order to find the equation of a line with the same slope that passes through the point (2, -5), we can use the point-slope form of the equation of a line.The point-slope form of the equation of a line is:y - y1 = m(x - x1)where m is the slope of the line, and (x1, y1) is a point on the line.In this case, we can plug in the values m = -1/2, x1 = 2, and y1 = -5 to get:y + 5 = -1/2(x - 2)Solving for y, we get:y = -1/2x - 4Therefore, the equation of the line that is parallel to the given line and passes through the point (2, -5) is Y = -1/2x - 4.

Answer:

Step-by-step explanation:

we conclude that at 5:00 p.m. there are 8 more inches of snow than at 8:00 a.m.

We know that at 8:00 a.m. there were t inches of snow in the ground.

At 5:00 p.m. there were 3t inches of snow in the ground.

Then the difference between the heights of the snow is:

3t- t = 2t

And we know that at 5:00 p.m. there were 12 inches of snow then we can solve the linear equation for t:

3t = 12in

t = (12in)/3 = 4 in

Replacing that in the difference of heights:

2t = 2*4in = 8in

From this, we conclude that at 5:00 p.m. there are 8 more inches of snow than at 8:00 a.m.

Let the variable n represent the unknown number.

Based on the statement "The sum of seven times a number and 16 is 163," we can logically deduce the following algebraic equation;

7n + 16 = 163

7n = 163 - 16

7n = 147

The 3 is repeating

Step-by-step explanation:

The minimum number of $0.10 stamps he needs to use is 1 stamp.

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:

Ori needed at least $1.47 in postage.

x represents the number of $0.44 cent stamps.

and, y represents the number of $0.10 cent stamps.

Cost 3 stamps

= 3 x 0.44

= 1.32

So, price of $0.10 stamps

= 1.47 - 1. 32

= $0.15

So, number of $0.10 stamps he needs to use

= 0.15/ 0.10

= 1.5

= 2 or 1 stamps

Savings is proportional to number of months by equation y = 15x

Rate constant for the relationship is k = 15

A proportional relationship is a relationship between two variables in which their ratios are equal. In other words, in a proportional relationship, one variable is always a constant value times the other. This constant is called the "rate constant".

If a and b are proportional to each other

then, a/b = k , here k is rate constant

Given,

graph of Miguel's savings is shown as straight line.

Number of months is denoted by x

Savings is denoted by y

Points denoted on graph are (2, 30) and (4 , 60)

Equation of the line

y - y₁ = [(y₂ - y₁)/(x₂ - x₁)] (x - x₁)

y - 30 = [(60 - 30)/(4 - 2)] (x - 2)

y - 30 = [(30)/(2)] (x - 2)

y - 30 = 15 (x - 2)

y - 30 = 15x - 30

y = 15x

Savings is proportional to number of months.

y/x = 15

Rate constant k = 15

Hence, by equation y = 15x, savings is proportional to number of months.

k = 15 is rate constant.
