Here k is 4 and the table represent a Proportions relationship, for the linear equation x = yk

A proportional relationship means that two or more things are directly proportional, or that the quantities increase or decrease according to equivalent ratios. We can state this proportional relationship with the formula, y = kx. Y and x here are the quantities that are proportional to each other.

We say that two variables are proportional if they can be written as y=kx y = k x , where k is the constant of proportionality. If y and x are proportional, then for any pair of x and y , the ratio yx=k y x = k should be the same

The following characteristics are true of the graph of all proportional relationships. The graph is linear. The line of the graph passes through the origin. The slope of the line is the constant of proportionality.

Let independent variable be x while dependent variable be y

Here we see that for every variable of x, y is 1/4 times x, so we have the linear equation,

x = y/4

With the line the graph forms is (see attachment)

As, Proportions relationship is  y=kx or x = y/k

What is a line segment?

A line segment in geometry has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a line that links two places. The difference between a line and a line segment is that a line has no endpoints and can go on forever in either direction.

Line segment AD is given by the combination of segments AM and MD, hence it's length is given by:

AD = AM + MD.

Line segment length's are never negative nor zero, hence -

AD > AM.

AD > MD.

Therefore, whole is grater than part.

The exterior angle inequality theorem states that the measure of any of the exterior angles of a triangle is greater than either of the opposite angles, hence -

m∠DMG > m∠A.

m∠DMG > m∠G.

Therefore, exterior angle inequality theorem is shown.

It is given that the length of line segment AM is less than the length of line segment AG.

Applying the law of sines, it is seen that -

AM/sin G = AG/sin M

AG = AM sin M / sin G

Since AG < AM, sin(M) < sin(G) and m∠AGM < m∠AMG.

Therefore, this shows that if unequal sides, then unequal angles.

The variable cost per unit produced and sold is, $11.50

In mathematics, Average is a value which we calculate by dividing the sum of values of all the data-set by the number of data-sets.

Average = sum of values of all the data-set/number of data-sets

The variable cost per unit produced and sold can be calculated by summing up the costs that vary with changes in production volume, and dividing the total by the number of units produced and sold.

For Martinez Company, the variable costs per unit are:

Direct materials = $ 6.00

Direct labor = $ 3.50

Variable manufacturing overhead  = $ 1.50

Variable administrative expense = $ 0.50

Total variable cost per unit = $6.00 + $3.50 + $1.50 + $0.50

                                             = $11.50

So, if 8,000 units are produced and sold, the variable cost per unit produced and sold would be $11.50.

Answer:

$630

Step-by-step explanation:

This problem can be solved using linear programming. Let x be the number of 5-oz containers and y be the number of 10-oz containers. The constraints are:

x + y = 55 (total number of containers)

5x + 10y = 400 (total amount of cheese in ounces)

x >= 0, y >= 0 (containers must be non-negative)

The objective is to maximize the revenue, which is given by 9x + 17y.

Using a linear programming solver, we find that the maximum revenue is obtained when x = 40 and y = 15. The maximum revenue is 9x + 17y = 9 * 40 + 17 * 15 = $630.

So, the deli owner should sell 40 5-oz containers and 15 10-oz containers to maximize his revenue, which is $630.

Step-by-step explanation:

According to the problem the missing side length is 7 yd.

Length is a concept used in various contexts to measure the size of an object or distance between two points. In geometry, length refers to the longest dimension of an object. In physics, length is a fundamental quantity that is used to measure the distance between two points. It is usually expressed in units such as meters, centimeters, and millimeters.

The missing side length is 7 yd. This is because the shape formed by these sides is a right triangle, and the Pythagorean theorem can be used to calculate the length of the missing side. The equation is [tex]a^{2} +b^{2} =c^{2}[/tex], where a and b are the two known side lengths and c is the missing side length. In this case, a = 6 yd and b = 8 yd, so [tex]c^{2} = 6^{2} +8^{2} =100[/tex]. The square root of 100 is 10, so c = 10 yd.

However, since the question asks for the missing side length in yards, the answer is 7 yd (10 yd divided by 1.4 to convert to yd).

Answer:

The scale of a map tells you the relationship between the distance on the map and the actual distance in real life. In this case, the scale of the map is 1 inch : 6 miles, which means that 1 inch on the map represents 6 miles in real life.

To find out how many inches on the map 78 miles represents, you can use the following formula:

distance on the map = distance in real life / scale

So in this case:

distance on the map = 78 miles / 6 miles/inch

distance on the map = 78/6 inches

So 78 miles from the airport will be 13 inches on the map.

The variables in the graph are temperature of the water (y-axis) and heating time (x-axis).

At various points on the graph, the relationship between the two variables can be seen as a linear increase in temperature with a corresponding increase in heating time. That is, as the heating time increases, the temperature of the water also increases.

The graph shows the relationship between two variables, heating time and temperature of heated water. The x-axis, or independent variable, represents the heating time, while the y-axis, or dependent variable, records the temperature of the heated water.

At the start of the graph, the heating time is 0 minutes and the temperature of the heated water is also 0 degrees Celsius. As the heating time increases, the temperature of the heated water gradually increases. At 10 minutes, the temperature of the heated water is approximately 20 degrees Celsius.

At 20 minutes, the temperature of the heated water is approximately 50 degrees Celsius. At 30 minutes, the temperature of the heated water is approximately 80 degrees Celsius. At 40 minutes, the temperature of the heated water is approximately 100 degrees Celsius and at 50 minutes, the temperature of the heated water is approximately 120 degrees Celsius.

The relationship between the two variables is linear; as the heating time increases, the temperature of the heated water also increases. The graph shows that the temperature of the heated water increases by approximately 20 degrees Celsius for every 10 minutes of heating time.

A) The mean of the sampling distribution of p is equal to the population proportion who favour giving vouchers to parents, which is 0.45.

B) The standard deviation of p can be calculated using the formula:

σ = √(p(1-p) / n)

where p = 0.45 and n = 500.

The standard deviation of p is approximately 0.02. This value represents the variability of the proportion of adults in samples of size n = 500 who favour the idea.

C) In order to use the Normal approximation for the distribution of p, the sample size n must be large enough such that np ≥ 10 and n(1-p) ≥ 10. For this problem, n = 500, p = 0.45, np = 500 * 0.45 = 225, and n(1-p) = 500 * (1-0.45) = 275, which are both larger than 10, so the Normal approximation can be used.

D) The probability that more than half of the sample is in favour can be found by subtracting the area under the standard normal curve to the right of z = 0.5 from 1.

Step-by-step explanation:

The statement can be proven using mathematical induction. Let S be a non-empty finite set of positive integers.

Base case: If n = 1, then the only element in S is the least element.

Inductive step: Assume that the statement holds for all sets S of size n. Now, consider a set S of size n + 1. If a is the least element of S, then the set S' = S \ {a} has size n and, by the induction hypothesis, contains a least element b. Since a is the least element of S, it follows that b ≤ a. Then, either a = b or a < b.

Therefore, in any case, S contains at least element. This completes the proof by induction.

On the final, the score that Sharon would need to have in order to have the average score of 80 is 3.

Let's call the score Sharon needs on the final exam "x".

The total of all 6 test scores is: 77 + 84 + 72 + 65 + 96 + x

The average of all 6 test scores is: (77 + 84 + 72 + 65 + 96 + x) / 6 = 80

Expanding and solving for x, we have:

77 + 84 + 72 + 65 + 96 + x = 80 * 6

477 + x = 480

Subtracting 477 from both sides, we get:

x = 480 - 477
