The transformation rule that describes the rotation from the original parallelogram ABCD to the image parallelogram A'B'C'D' is (x, y) → (–y, x).

The rule that describes the transformation from the original parallelogram ABCD to the image parallelogram A'B'C'D' is (x, y) → (–y, x).

To understand this, let's apply the transformation rule to each vertex of the original parallelogram ABCD:

Point A (2, 5) becomes A' (-5, 2).

Point B (5, 4) becomes B' (-4, 5).

Point C (5, 2) becomes C' (-2, 5).

Point D (2, 3) becomes D' (-3, 2).

By applying the transformation rule, we observe that the x-coordinate of each point becomes the negative of the original y-coordinate, and the y-coordinate becomes the original x-coordinate.

This transformation is a 90-degree counterclockwise rotation about the origin (0, 0) on the coordinate plane. The image parallelogram A'B'C'D' is obtained by rotating the original parallelogram ABCD by 90 degrees counterclockwise.

Visually, this transformation can be seen as the original parallelogram being rotated around the origin, where the x-axis becomes the y-axis, and the y-axis becomes the negative x-axis.

Therefore, the transformation rule that describes the rotation from the original parallelogram ABCD to the image parallelogram A'B'C'D' is (x, y) → (–y, x).

Answer:

b = -4

Step-by-step explanation:

Divide by 2:

b + 12 = 8

b = -4

Answer:

B = -4

Step-by-step explanation:

Take,

-4 + 12 = 8

Then,

8 x 2 = 16.

We are given that ||u + v|| = ||u|| + ||v||, where ||u|| and ||v|| denote the magnitudes of the vectors u and v, respectively. This equation is known as the triangle inequality.

From the triangle inequality, we know that the magnitude of the sum of two vectors cannot be less than the sum of the magnitudes of the vectors. This is because in any triangle, the sum of the lengths of any two sides is always greater than or equal to the length of the third side.

Therefore, if ||u + v|| = ||u|| + ||v||, then the vectors u and v must lie on the same line and point in the same direction. This is because if the vectors were not collinear, then ||u + v|| would be greater than ||u|| + ||v||, due to the triangular shape formed by the vectors.

In other words, the vectors u and v must be scalar multiples of each other, or u = kv for some nonzero scalar k. This is because in this case, the magnitude of u + v is equal to the magnitude of (k+1)v, which is equal to (k+1)||v||. Therefore, the condition ||u + v|| = ||u|| + ||v|| is satisfied if and only if u and v are scalar multiples of each other.

So, if ||u + v|| = ||u|| + ||v||, then we can conclude that u and v are collinear and point in the same direction, or u = kv for some nonzero scalar k.

A system of equations, or equation system, is a collection of finite equations for which common solutions are sought. A set of simultaneous equations may also be referred to as an equation system.

While using the System of equation:

we can say that:

country A won medal  = X

country B won medal  = Y

country C won medal  = Z

Total number of medals have  = 123

so we can say that

X + Y + Z = 123

Country B won 8 more medals than Country C.

So Y = Z + 8

Country A won 34 more medals than the total amount won by the other two.

X - (Y + Z) = 34

From the equation

(Y + Z)  = 123 - X

Putting the value (Y + Z)

X - (123 - X) = 34

2X - 123 = 34

2X = 157

X = 157/2

X = 78.5

Finding the value of Z.

when X = 78.5, Y = Z + 8

X + Y + Z = 123

78.5 + (Z + 8) = 123

86.5 + 2Z = 123

Z  = 36.5/2

Z = 18

Finding the value of Y

Y = Z + 8

  = 18 + 8

  =  26

So,

country A won medal  = 87

country B won medal  = 18

country C won medal  = 26

The mid point between the two points is at 13/8 .

A line segment is  a line of fixed measure .

The line segment extends from (-3/4) to  \(\rm 2 \dfrac{1}{2}\)

i.e the line extends form -3/4 to 5/2

To find the mid point , the total distance needs to be determined

So the distance between the two point is

(5/2) + (3/4) = 13/8

The mid point is at half the distance of this

so it is at 13/8 from both the points

Any point at 13/8 distance from 5/2  towards (-3/4) will be

= (5/2) - (13/8)

= 7/8

The numbers of the jerseys of 5 randomly selected Carolina Panthers would fall under the category of quantitative discrete data.

Quantitative data are numerical measurements or counts that can be added, subtracted, averaged, or otherwise subjected to arithmetic operations. Discrete data, on the other hand, can only take on specific, whole number values, as opposed to continuous data which can take on any value within a range.

Qualitative data, on the other hand, are non-numerical data that cannot be measured or counted numerically. Examples include colors, names, opinions, and preferences. Since the numbers of the jerseys are specific numerical values, they are considered quantitative data.

Since they can only take on specific, whole number values (i.e. the jersey numbers are not continuous values like weights or heights), they are considered discrete data. Therefore, the correct option for the given question is option "quantitative discrete".

If,

the values of x and y that satisfy the system of equations are x = -14/11 and y = 13/11.

To solve the system of linear equations using one of the three methods (elimination, substitution, or matrix inversion), let's first check the rank of matrix A and [A b].

The matrix A is a 3x2 matrix:

A = [2 3]

[-1 4]

[5 -6]

To find the rank of A, we can perform row operations to reduce the matrix to row-echelon form. The rank of A is equal to the number of non-zero rows in its row-echelon form.

Performing row operations on A, we have:

Row 2 = Row 2 + 0.5 * Row 1

Row 3 = Row 3 - 2.5 * Row 1

The row-echelon form of A is:

A = [2 3]

[0 5]

[0 -21]

Since A has two non-zero rows, the rank of A is 2.

Next, we check the rank of [A b]. The vector b is a 3x1 vector:

b = [1]

[6]

[-3]

We can append vector b as an additional column to matrix A:

[A b] = [2 3 1]

[-1 4 6]

[5 -6 -3]

Performing row operations on [A b], we have:

Row 2 = Row 2 + Row 1

Row 3 = Row 3 - 2 * Row 1

The row-echelon form of [A b] is:

[A b] = [2 3 1]

[0 7 7]

[0 -12 -5]

Since [A b] has two non-zero rows, the rank of [A b] is also 2.

Since the rank of A and [A b] are both 2, we can proceed with solving the system of linear equations using any of the three methods.

Let's use the method of matrix inversion to solve the system.

The system of equations can be written as a matrix equation:

Ax = b

To find x, we can multiply both sides of the equation by the inverse of A:

\(A^(-1) * A * x = A^(-1) * b\)

\(I * x = A^(-1) * b\)

\(x = A^(-1) * b\)

To find the inverse of A, we can use the formula:

\(A^(-1) = (1 / (ad - bc)) * [d -b][-c a]\)

Plugging in the values of matrix A, we have:

\(A^(-1) = (1 / (2 * 4 - 3 * -1)) * [4 -3][1 2]\)

Calculating the inverse of A, we have:

A^(-1) = (1 / 11) * [4 -3]

[1 2]

Multiplying A^(-1) by vector b, we have:

\(x = (1 / 11) * [4 -3] * [1][6][-3]\)

Calculating the product, we get:

x = (1 / 11) * [4 * 1 + -3 * 6]

[1 * 1 + 2 * 6]

Simplifying, we have:

x = (1 / 11) * [-14]

[13]

Therefore, the solution to the system of linear equations is:

x = -14/11

y = 13/11

Hence, the values of x and y that satisfy the system of equations are x = -14/11 and y = 13/11.

Step-by-step explanation:

First calculate the slope. \(\frac{y2-y1}{x2-x1}\). In this case, the slope is \(\frac{4}{5}\).

If you look at all of the answer choices, they are in slope - intercept form. This makes it easier! All you have to do is find an equation with the slope 4/5 that uses the point (4,1) or (9,5).

The standard slope intercept form for a point (a,b) is

y-b = m(x-a).

Remember that two negatives equal a positive.

Substitute in the slope for m and (4,1) or (9,5) for the point (a,b).

(a) The estimated cost for the Publinskys’s house if they use their talents to do some of the work themselves (all plumbing, painting and interior decoration) is $139 x 2,100 x 0.87.

To calculate the estimated cost for the Publinskys' house if they do some of the work themselves, we need to determine the costs for the tasks they will be handling and add them to the remaining tasks that will be completed by contractors.

The tasks the Publinskys will handle themselves are plumbing, painting, and interior decoration, which account for a total of 4% + 5% + 4% = 13% of the total cost.

Therefore, the estimated cost for the Publinskys' house if they do some of the work themselves is:

Estimated cost = $139/sq.ft. x 2,100 sq.ft. x (100% - 13%)

Calculating the expression:

Estimated cost = $139/sq.ft. x 2,100 sq.ft. x 87%

Estimated cost = $139 x 2,100 x 0.87

(b)  The estimated cost for the Publinskys' house if they use contractors to complete all of the work is the same as the total cost of the house.

To calculate the estimated cost for the Publinskys' house if they use contractors to complete all of the work, we need to consider the costs for all the tasks listed in the bank's average cost information.

The estimated cost for the Publinskys' house using contractors is:

Estimated cost = $139/sq.ft. x 2,100 sq.ft. x 100%

Calculating the expression:

Estimated cost = $139 x 2,100 x 1

To find the slope, find the difference in the y coordinates and  divide it by the difference in the x coordinates .

y coordinates:   16 - (-6) = 22

x coordinates ;   15 - (-19) = 34

22/ 34 = 11/17

1.1. The Pearson's coefficient of skewness is approximately 1.643.

1.2. The quartile deviation is approximately 12.05.

1.3. The quartile coefficient of skewness is approximately 0.251.

1.4. This is because the semi-interquartile range uses only the middle 50% of the data, which is more resistant to extreme values.

1.5. The standard deviation can be used to make comparisons between datasets that have different means and ranges, whereas the range cannot.

1.6.  One can also use Box plots instead of range to visualize the distribution of the data, which provides more information about the shape of the distribution than the range alone.

1.1. Pearson's coefficient of skewness is given by:

Skewness = 3 * (Mean - Median) / Standard Deviation

Substituting the values given, we get:

Skewness = 3 * (111 - 107.91) / 18.36

Skewness = 1.643

Therefore, the Pearson's coefficient of skewness is approximately 1.643.

1.2. Quartile deviation is given by:

Quartile deviation = (Q3 - Q1) / 2

Substituting the values given, we get:

Quartile deviation = (122.64 - 98.54) / 2

Quartile deviation = 12.05

Therefore, the quartile deviation is approximately 12.05.

1.3. Quartile coefficient of skewness is given by:

Quartile coefficient of skewness = (Q3 + Q1 - 2 * Median) / (Q3 - Q1)

Substituting the values given, we get:

Quartile coefficient of skewness = (122.64 + 98.54 - 2 * 107.91) / (122.64 - 98.54)

Quartile coefficient of skewness = 0.251

Therefore, the quartile coefficient of skewness is approximately 0.251.

1.4. The main advantage of the semi-interquartile range is that it is less affected by outliers than other measures of dispersion such as range and standard deviation. This is because the semi-interquartile range uses only the middle 50% of the data, which is more resistant to extreme values.

1.5. The standard deviation is generally regarded as a better measure of dispersion than the range for the following reasons:

Unlike the range, the standard deviation takes into account all the data points in the sample, not just the extreme values.

The standard deviation is a more precise measure of dispersion than the range because it considers the variation of each data point from the mean, whereas the range only considers the difference between the highest and lowest values.

The standard deviation can be used to make comparisons between datasets that have different means and ranges, whereas the range cannot.

1.6. The disadvantages of the range can be largely overcome by using other measures of dispersion such as the standard deviation or the semi-interquartile range. These measures are less affected by outliers and provide a more accurate representation of the spread of the data. Additionally, one can also use Box plots instead of range to visualize the distribution of the data, which provides more information about the shape of the distribution than the range alone.
