The type of sampling method used by Mrs. Trahan is clustering method. The correct option is 4.

A population is divided into many clusters that are representative of homogenous traits and have an equal probability of being included in the sample using the sampling technique known as cluster sampling.

Using this sampling approach, researchers examine a sample that includes a variety of sample criteria, including demographics, lifestyle, background, or any other population characteristic that may be the subject of the research being done. This approach is typically used when a statistical population is made up of comparable but internally heterogeneous groupings. Cluster sampling divides the population into smaller, more productive groups, allowing the researchers to obtain data without picking the full population.

Answer:

We can solve for y in the equation y = 2y - 2 by substituting y = 2x - 5.

Starting with y = 2y - 2, we substitute y = 2x - 5:

2x - 5 = 2(2x - 5) - 2

Expanding the right side:

2x - 5 = 4x - 12

Next, we isolate y by subtracting 2x from both sides:

-2x - 5 = 4x - 12

Adding 2x to both sides:

-5 = 6x - 12

Adding 12 to both sides:

7 = 6x

Finally, we divide both sides by 6 to solve for x:

x = 7/6

So, y = 2x - 5 = 2(7/6) - 5 = 7/3 - 5 = -14/3.

Therefore, y = -14/3 is the solution to the system of equations y = 2y - 2 and y = 2x - 5.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, The ratio of flour to eggs in a pancake recipe is constant.

The pancake recipe uses 5 cups of flour for each egg.

Since,

With one egg we need a total number of cups of flour = 5

Thus,

For 2 eggs, we need a total number of cups of flour = 5*2

For 2 eggs, we need a total number of cups of flour = 10

For 5 eggs, we need a total number of cups of flour = 5*5

For 5 eggs, we need a total number of cups of flour = 25

Thus, the required table

Cups of Flour               Number of Eggs

We are asked to find there are how many deciliters which is equivalent to 9 cups,

Since,

1 cup = 0.237 liters

1 liter = 10 dL

Therefore,

1 cup = 0.237 x 10 = 2.4 dL

Answer:

543 fee

Step-by-step explanation:

The difference between 535 and -8 is the distance between them, but it is not specified in what unit this distance should be measured. If you meant to find the difference in feet, then:

535 - (-8) = 535 + 8 = 543

So the distance between 535 and -8 in feet is 543 feet.

The statement that describes the relationship is: option B.

The situation that can be represented by the equation y = 12x is: B. "Yvonne has y dollars. This is one half more dollars than her friend Marie who has x dollars."

In the equation y = 13x, y is equal to 13 times x. This means that y increases by a factor of 13 for every increase in x.

In the equation y = x + 13, y is equal to x plus 13. This means that y is always 13 more than x.

Therefore, the answer is:

B. "In y = 13x, the value of y is 13 times the value of x, and in y = x + 13, the value of y is 13 more than the value of x."

The equation y = 12x means that y is equal to 12 times x. In the given situation, Yvonne has y dollars and Marie has x dollars. Yvonne has 12 times more dollars than Marie, and one half more than Marie. Therefore, the situation can be represented by y = 12x.

The correct answer is:

B. "Yvonne has y dollars. This is one half more dollars than her friend Marie who has x dollars."

The measure of angles ∠DEM and ∠MEF will be the same which is 41.8 degrees.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

Adjacent angle - In math, two points are nearby in the event that they have a typical side and a typical vertex.

EM bisects DEF and ∠DEF = 83.6°. Then the measure of the angle ∠DEM and ∠MEF will be the same. Then we have

∠DEM + ∠MEF = ∠DEF

The algebraic fraction which is an equivalent fraction with the denominator 24a^3b^2 is 15b/24a^3.

To find an equivalent fraction with the denominator 24a^3b^2, we need to find a common denominator for the two fractions 5b and 8a^3. This common denominator is 24a^3b^2.

To find an equivalent fraction for 5b, we can multiply both the numerator and denominator by the same factor to obtain the desired denominator. To do this, we need to find a factor that would give us a denominator of 24a^3b^2 when multiplied with 8a^3.

The factor that would give us a denominator of 24a^3b^2 is 3.

So, the equivalent fraction for 5b with the denominator 24a^3b^2 is (5b * 3)/(8a^3 * 3) = 15b/24a^3.
