Step-by-step explanation:

This would be a rhombus.

In a rhombus, all sides are equal and opposite sides are parallel.

Answer:

Therefore, Kiran swam approximately 0.189z laps in the pool.

Step-by-step explanation:

Let's assume the number of laps Kiran swims to be "x".

From the given information, we know that Clare swims 95 times as many laps as Kiran. Therefore, we can write an equation:

18 = 95x

To solve for x, we can isolate it by dividing both sides of the equation by 95:

x = 18/95

x = 0.189

The value of the side length PR using Trigonometric ratio is: PR = 3/√2

Pam takes 17 minutes for haircut and 49 minutes for hair coloring. The solution has been obtained by using the arithmetic operations.

What are arithmetic operations?

Using the four basic operations, also referred to as "arithmetic operations," all real numbers may be explained. In mathematics, operations such as division, multiplication, addition, and subtraction come before operations such as quotient, product, sum, and difference.

Let x be the time taken for haircut and y be for hair coloring.

Now, she gave 2 haircuts and colored the hair of 1 client in 83 minutes.

So, using addition operation, we get

2x + y = 83         ...(1)

Similarly, she gave 1 haircut and colored the hair of 3 clients in 164 minutes.

So, we get

x + 3y = 164          ...(2)

From (1), we get

y = 83 - 2x

On substituting this in (2), we get

⇒ x + 3 * (83 - 2x) = 164

⇒ x + 249 - 6x = 164

⇒ 249 - 5x = 164

⇒ 5x = 85

⇒ x = 17

So,

⇒ y = 83 - 2 (17)

⇒ y = 83 - 34

⇒ y = 49

Hence, Pam takes 17 minutes for haircut and 49 minutes for hair coloring.

Distance is a numerical measurement of the amount of space between two points. It is the length of a path that connects two points in a space, usually measured in units such as meters, kilometers, miles, etc.

In Euclidean space (a type of space

We can use the distance formula to find the possible coordinates of point A. The distance formula between two points (x1, y1) and (x2, y2) is:

d = √((x2 - x1)² + (y2 - y1)²)

Let the coordinates of point A be (x, y), where x = -2 (the x-coordinate of point A is -2, as given in the problem).

Then, we can write the distance formula as:

5 = √((2 - (-2))²+ (1 - y)²)

Simplifying this equation, we get:

25 = (2 - (-2))²+ (1 - y)²

25 = 16 + (1 - y)²

To determine the probability that the herd's daily production will be between 32.3 and 36.9 liters, we must compute the z-scores for each number and use a standard normal distribution table to calculate the area under the curve between those z-scores.

To find out the z - scores we need use z-score formula:

Z = X−μ / σ

where μ  is the mean, σ is the standard deviation and X is the observed value. In the problem μ  is 30 liters, X₁ = 32.3 liters & X₂ = 36.9 liters and σ = 8.2 liters.

Substituting the values in the equation to find the z-score for 32.3 liters is:

z₁ = (32.3 - 30) / 8.2 = 0.2804

z₁ = 0.28049

Substituting the values in the equation to find the z-score for 36.9 liters is:

z₂ =( 36.9 - 30) / 8.2 =  0.8414

z₂ = 0.8414

We can determine the area under the curve between these two z-scores using a conventional normal distribution table. The area between z = 0.28049 and z = 0.8414 and the probability is approximately 0.1894.

According to the algebraic expressions, the sum of four smaller rectangles is 96.

First, let's consider the figure as one large rectangle. To find the area of a rectangle, we multiply its length by its width. In this case, the length of the rectangle is 8 and the width is 6 + 2 + 4 = 12. Therefore, the expression for the area of the rectangle can be written as:

Area = length x width

Area = 8 x 12

Area = 96

So the area of the figure as one large rectangle is 96 square units.

To find the area of each rectangle, we'll use the formula for the area of a rectangle, which is length x width. We can see from the figure that:

Rectangle A has a length of 8 and a width of 6

Rectangle B has a length of 8 and a width of 2

Rectangle C has a length of 4 and a width of 6

Rectangle D has a length of 4 and a width of 2

Therefore, the expressions for the area of each rectangle can be written as:

Area_A = length x width

Area_A = 8 x 6

Area_A = 48

Area_B = length x width

Area_B = 8 x 2

Area_B = 16

Area_C = length x width

Area_C = 4 x 6

Area_C = 24

Area_D = length x width

Area_D = 4 x 2

Area_D = 8

To find the total area of the figure, we simply add up the areas of the four rectangles. Therefore, the expression for the area of the figure as a sum of four smaller rectangles can be written as:

What is Pentagon?

A pentagon is a geometric shape that has five sides and five angles. It is a two-dimensional polygon, which means it is a flat shape with straight sides.

To find the coordinates of the dilated pentagon A'B'C'D'E', we need to multiply the coordinates of each vertex of pentagon ABCDE by the scale factor. Since the origin is the center of dilation, we can use the formula:

(x', y') = k(x, y)

where (x, y) are the original coordinates of a vertex, k is the scale factor, and (x', y') are the new coordinates of the corresponding vertex.

To find the scale factor, we can use the distance formula to find the distance between the origin and any one of the vertices. Let's use vertex A for convenience:

Distance OA = sqrt((-1-0)² + (1-0)²) = sqrt(2)

Distance OA' = k * Distance OA

We want to find the scale factor that will result in a dilation centered at the origin, so we want OA' to be the desired distance between the origin and A'. Let's say that distance is d. Then:

d = k * sqrt(2)

Solving for k, we get:

k = d / sqrt(2)

We are not given the desired distance between the origin and A', so we cannot determine the exact value of k. However, we can still determine which answer choice represents the correct dilation.

Let's try answer choice A:

(x', y') = (3/7x, 3/7y)

This represents a dilation with a scale factor of 3/7. But we already know that the scale factor should be d / sqrt(2). Since d could be any value, we cannot say for sure whether 3/7 is the correct scale factor.

Answer choice B:

(x', y') = (x + 3/7, y + 3/7)

This represents a translation, not a dilation. Therefore, it cannot be the correct answer.

Answer choice C:

(x', y') = (x + 7/3, y + 7/3)

This represents a dilation with a scale factor of 1. This is not the correct scale factor, since we know that the distance between the origin and A' should be greater than the distance between the origin and A.

Answer choice D:

(x', y') = (7/3x, 7/3y)

This represents a dilation with a scale factor of 7/3. This is the correct scale factor, since we know that the distance between the origin and A' should be d, which is 7/3 times the distance between the origin and A.

Answer:

the mean absolute deviation for the given data set is 1.86.

Step-by-step explanation:

To find the mean absolute deviation, we first need to find the mean of the data set.

Mean = (1.25 + 3.50 + 2.55 + 8.20 + 4.80 + 0.30 + 0.75 + 2.25) / 8 = 3.07

Next, we find the absolute deviation of each data point from the mean by subtracting the mean from each data point and taking the absolute value:

|1.25 - 3.07| = 1.82

|3.50 - 3.07| = 0.43

|2.55 - 3.07| = 0.52

|8.20 - 3.07| = 5.13

|4.80 - 3.07| = 1.73

|0.30 - 3.07| = 2.77

|0.75 - 3.07| = 2.32

|2.25 - 3.07| = 0.82

Then, we find the mean of these absolute deviations:

Mean absolute deviation = (1.82 + 0.43 + 0.52 + 5.13 + 1.73 + 2.77 + 2.32 + 0.82) / 8

Mean absolute deviation = 1.86

Therefore, the mean absolute deviation for the given data set is 1.86.
