Drag the ordered pairs to match the points shown on the coordinate grid.

The values for \((dw/dx)y\) is\(-2*pi^2\)and\((dw/dz)y\) is 0.

We are given:

\(w = x^2 y^2 z^2\)

ysinz zsinx = 0

Part a: To find (dw/dx)y, we need to differentiate w with respect to x, treating y as a constant, and evaluate the result at (x,y,z) = (-pi, -1, 2pi).

Taking the partial derivative of w with respect to x, we get:

\(∂w/∂x = 2xy^2 z^2\)

So, \((dw/dx)y = 2xy^2 z^2.\)

Substituting (x,y,z) = (-pi, -1, 2pi), we get:

\((dw/dx)y = 2*(-pi)(-1)^2(2pi)^2 = 8pi^4\)

Therefore,\((dw/dx)y = 8pi^4.\)

Part b: To find (dw/dz)y, we need to differentiate w with respect to z, treating x and y as constants, and evaluate the result at (x,y,z) = (-pi, -1, 2pi).

Taking partial derivative of w with respect to z, we get:

\(∂w/∂z = 2x^2 y^2 z\)

Using the given equation ysinz zsinx=0, we can infer that either y=0 or sinz=0 or z=0 or sinx=0.

If y=0, then \((dw/dz)y=0.\)

If sinz=0, then z=kπ where k is an integer. But z=2π, so k=2. Thus, z=2π.

If z=0, then\((dw/dz)y=0.\)

If sinx=0, then x=jπ where j is an integer. But x=-π, so j=-1. Thus, x=-π.

Substituting (x,y,z) = (-pi, -1, 2pi), we get:

\((dw/dz)y = 2*(-pi)^2*(-1)^2*(2pi) = 4pi^3\)

Therefore, \((dw/dz)y = 4pi^3.\)

The number of possible king-queen pairs can be determined by multiplying the number of candidates for king by the number of candidates for queen.

To calculate the number of king-queen pairs, we multiply the number of candidates for king by the number of candidates for queen. In this case, there are four candidates for homecoming queen and three candidates for king. Therefore, the total number of king-queen pairs would be 4 multiplied by 3, which equals 12.

Each candidate for king can be paired with each candidate for queen, resulting in multiple possible combinations. By multiplying the number of candidates for each position, we account for all possible pairings. In this scenario, there are three potential kings and four potential queens. For each king, there are four possible queens he can be paired with. Since there are three kings, we multiply 3 by 4 to get the total number of 12 king-queen pairs.

What is the slope of a line?

The slope of a line is the tangent of the angle that the line makes with the positive direction of the x-axis. It signifies the rise in the y-variable for a unit change in the x-variable.

If the line passes through the points (x, y) and (x, y), then the slope of the line, m = (y - y)/(x - x).

\(y < \frac{1}{3}x + 2\\y \leq -2x + 2\)

Step-by-step explanation:

The equation of a line can be simply found via slope-intercept form-y = mx+b,

where m is the slope and b is the y-intercept.

To find the y-coordinate of point P on the unit circle, given that its x-coordinate is 5/13, we can utilize the Pythagorean identity for points on the unit circle.

The Pythagorean identity states that for any point (x, y) on the unit circle, the following equation holds true:

x^2 + y^2 = 1

Since we are given the x-coordinate as 5/13, we can substitute this value into the equation and solve for y:

(5/13)^2 + y^2 = 1

25/169 + y^2 = 1

To isolate y^2, we subtract 25/169 from both sides:

y^2 = 1 - 25/169

y^2 = 169/169 - 25/169

y^2 = 144/169

Taking the square root of both sides, we find:

y = ±sqrt(144/169)

Since we are dealing with points on the unit circle, the y-coordinate represents the sine value. Therefore, the y-coordinate of point P is:

y = ±12/13

So, the y-coordinate of point P can be either 12/13 or -12/13.

The domain and range of the inverse relation are {2, 3, 5, 7, 8} for both.

The given relation consists of the points 2, 3, 5, 7, and 8. To find the domain and range of the inverse relation, we need to swap the x-values with the y-values. The resulting set of values will represent the domain and range of the inverse relation.

In the given relation, the x-values are 2, 3, 5, 7, and 8, and the corresponding y-values are not provided. To find the inverse relation, we swap the x-values with the y-values.
After swapping the values, we obtain the following set of points: (2, 2), (3, 3), (5, 5), (7, 7), and (8, 8). These points represent the inverse relation.
The domain of the inverse relation is the set of x-values from the swapped points, which is {2, 3, 5, 7, 8}. This means that these are the values for which there exist corresponding y-values in the original relation.
Similarly, the range of the inverse relation is the set of y-values from the swapped points, which is also {2, 3, 5, 7, 8}. These are the values that correspond to the x-values in the original relation.
Therefore, the domain and range of the inverse relation are {2, 3, 5, 7, 8} for both.

Here, x value of 8 would be located on the left tail of the normal distribution curve, 3.67 standard deviations below the mean (μ=22.3) and with a very low value in terms of percentile or probability (0.015%).

To indicate where the given x value of 8 would be on the curve, we need to plot it on a normal distribution curve with a mean (μ) of 22.3 and a standard deviation (σ) of 3.9.
First, we need to convert the given x value of 8 into a z-score by using the formula:  z = (x - μ) / σ
Plugging in the values, we get: z = (8 - 22.3) / 3.9 = -3.67
This means that the value of 8 is located 3.67 standard deviations below the mean.
Next, we need to find this point on the normal distribution curve. We can use a z-score table or a graphing calculator to find the corresponding area under the curve.
If we use a z-score table, we can look up the area to the left of -3.67, which is 0.00015. This means that only 0.015% of the data falls below this point.
To plot this on the curve, we can locate the mean (μ) and mark it as the center of the curve. Then, we can count 3.67 standard deviations to the left of the mean and mark this as the point where the value of 8 would be located.

the lunch cost, including tax and tip 67.31$.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, the Patterson family went to eat lunch at a new restaurant. They spent $52.30 on their meal. The restaurant will add a 7 1/4% tax to the cost of the meal.

total cost after the tax = 52.30*(1 + 7 1/4)%

total cost after the tax = 52.30* 7.25/100 + 52.30

total cost after the tax = 3.79 + 52.30

total cost after the tax = 56.09

Since,

Mr Patterson was very happy with the food and service so he gave a 20% tip to the waitress.

Thus,

Total cost after the tip = 56.09(1 +20/100)

Total cost after the tip = 56.09 * 1.2

Total cost after the tip =  67.308

Therefore, the lunch cost, including tax and tip 67.31$.

Answer:

To find the average distance away from the mean, we need to first find the mean distance from the mean. To do this, we need to find the mean of the distances from the mean:

|32 - 33| = 1

|45 - 33| = 12

|23 - 33| = 10

|35 - 33| = 2

|30 - 33| = 3

Mean distance from the mean = (1 + 12 + 10 + 2 + 3) / 5 = 6. However, the question asks for the average distance away from the mean, so we need to take the absolute value of this result:

Average distance away from the mean = |6| = 6

To find the mean absolute deviation, we first need to find the deviations from the mean:

12.7 - 15.2 = -2.5

22 - 15.2 = 6.8

23.5 - 15.2 = 8.3

24 - 15.2 = 8.8

11 - 15.2 = -4.2

22 - 15.2 = 6.8

Next, we need to take the absolute value of each deviation:

|-2.5| = 2.5

|6.8| = 6.8

|8.3| = 8.3

|8.8| = 8.8

|-4.2| = 4.2

|6.8| = 6.8

The sum of these absolute deviations is:

2.5 + 6.8 + 8.3 + 8.8 + 4.2 + 6.8 = 37.4

To find the mean absolute deviation, we divide this sum by the number of data points:

Mean absolute deviation = 37.4 / 6 = 6.23
