Answer:

Step-by-step explanation:

Jasmine makes $2.08 more per hour cleaning a larger house compared to a smaller house.

Pricing strategies refer to the methods and techniques used by businesses or companies to set the prices of their products or services.

Let's first calculate the hourly rate Jasmine charges for cleaning a house with 2 bathrooms:

She charges $50 for a house with 3 bedrooms and 2 bathrooms, and it takes her 3 hours to clean it, so her hourly rate is:

⇒ $50 ÷ 3 hours = $16.67/hour

Now let's calculate the hourly rate she charges for cleaning a house with 3 or 4 bathrooms:

She charges $75 for a house with 3 to 4 bathrooms, and it takes her 4 hours to clean it, so her hourly rate is:

⇒ $75 ÷ 4 hours = $18.75/hour

Therefore, Jasmine makes $18.75/hour cleaning a larger house compared to $16.67/hour cleaning a smaller house.

To find out how much more Jasmine makes per hour cleaning a larger house compared to a smaller house, we can subtract the hourly rate for a smaller house from the hourly rate for a larger house:

⇒ $18.75/hour - $16.67/hour = $2.08/hour

So, Jasmine makes $2.08 more per hour cleaning a larger house compared to a smaller house.

Answer:

Step-by-step explanation:

Therefore, the rotated triangle has vertices at (-5, -10), (-3, -1), and (-4, -2), which forms a new triangle.

In mathematics, a vertex refers to a point where two or more lines, edges, or curves meet. In geometry, a vertex is a point where two or more edges of a polygon or polyhedron intersect. For example, in a triangle, each of the three points where the sides meet is a vertex.

A vertex is a fundamental unit of a graph, which is a collection of vertices connected by edges. Each vertex represents an entity or object, and the edges represent the relationships or connections between them. For example, in a social network graph, the vertices could represent individual users, and the edges could represent their friendships or connections with other users.

To perform a 270° counterclockwise rotation of a point about a center point, we can use the following formula:

[tex](x', y') = (x - a) * cos(theta) - (y - b) * sin(theta) + a, (x - a) * sin(theta) + (y - b) * cos(theta) + b[/tex]

where (x, y) is the original point, (x', y') is the rotated point, (a, b) is the center point, and theta is the angle of rotation in radians.

Let's first find the center point C(-5, -4) of the rotation. Then, we'll apply the formula to each vertex of the triangle to find its new location after the rotation.

[tex]Center point C = (-5, -4)[/tex]

Vertex P(-13, -3):

[tex]x' = (-13 - (-5)) * cos(270^{0} ) - (-3 - (-4)) * sin(270^{0} ) + (-5) = -5[/tex]

[tex]y' = (-13 - (-5)) * sin(270) + (-3 - (-4)) * cos(270) + (-4) = -10[/tex]

So, after the rotation, vertex P is at (-5, -10).

Vertex Q(-7, 3):

[tex]x' = (-7 - (-5)) * cos(270) - (3 - (-4)) * sin(270) + (-5) = -3[/tex]

[tex]y' = (-7 - (-5)) * sin(270) + (3 - (-4)) * cos(270) + (-4) = -1[/tex]

So, after the rotation, vertex Q is at (-3, -1).

Vertex R (-6, 2):

[tex]x' = (-6 - (-5)) * cos(270) - (2 - (-4)) * sin(270) + (-5) = -4\\y' = (-6 - (-5)) * sin(270) + (2 - (-4)) * cos(270) + (-4) = -2[/tex]

So, after the rotation, vertex R is at (-4, -2).

Scatterplots and correlation never prove causation. Causation may only be determined by well-designed experiments.

A scatterplot is a type of graph commonly used to observe and visually represent the relationships between variables. Variable values ​​are represented by dots. The position of the points on the vertical and horizontal axes indicates the value of each data point. Therefore, scatterplots use Cartesian coordinates to display the values ​​of the variables in the dataset. A scatterplot is also called a scatter graphs, scatter charts, or scattergrams.

Correlation means association, and more specifically, it measures how well two variables are related. Correlation analysis have three possible outcomes: Positive correlation, negative correlation, no correlation.

Based on the general properties of the MAD and the characteristics of the data sets, these matches seem reasonable.

In statistics, a dataset is a collection of data that is organized in a specific way. Typically, a dataset consists of multiple data points, where each data point represents an observation or measurement of a particular variable or set of variables.

We can make some general observations to match the data sets to the appropriate MAD value without actually calculating them:

The MAD measures the average distance between each data point and the median of the data set.

Therefore, the larger the MAD value, the more spread out the data set is.

Data set 1 will have the smallest MAD value, since it is the most tightly clustered around the median.

Data set 3 will have the largest MAD value, since it is the most spread out around the median.

Data set 2 will have a MAD value between those of data sets 1 and 3.

Based on these observations, we can match the data sets to the appropriate MAD value as follows:

Data set 1 has the smallest MAD value (7).

Data set 2 has a medium MAD value (9).

Data set 3 has the largest MAD value (11).

Of course, without actually calculating the MAD values, we can't say for certain whether these matches are correct.

Therefore, based on the general properties of the MAD and the characteristics of the data sets, these matches seem reasonable.

Scott Salman's net pay after subtracting all of his deductions is $1,620.26.

How To calculate Scott Salman's net pay?

To calculate Scott Salman's net pay, we need to first calculate his commission earnings and then subtract all of his deductions.

Commission Earnings:

3% of the first $20,000 in sales = $600

4% of the next $10,000 in sales = $400

6% of all sales over $30,000 = 6% × ($45,550 - $30,000) = $930

Total commission earnings = $600 + $400 + $930 = $1,930

Now we can calculate his gross pay by adding his commission earnings to his base salary:

Gross Pay:

Base salary = 0 (not given)

Commission earnings = $1,930

Total gross pay = $1,930

Next, we need to calculate his deductions. We'll assume the following rates for each deduction:

FICA: 7.65%

Medicare: 1.45%

Federal withholding: based on the IRS tax tables (not provided)

State disability insurance: 1%

State withholding: based on the state tax tables (not provided)

Retirement contribution: $45

Savings bond: $50

Charitable contributions: $20

Deductions:

FICA = 7.65% × $1,930 = $147.45

Medicare = 1.45% × $1,930 = $27.99

Federal withholding = based on the IRS tax tables (not provided)

State disability insurance = 1%×$1,930 = $19.30

State withholding = based on the state tax tables (not provided)

Retirement contribution = $45

Savings bond = $50

Charitable contributions = $20

Total deductions = $147.45 + $27.99 + $19.30 + $45 + $50 + $20 = $309.74

Finally, we can calculate Scott Salman's net pay by subtracting his total deductions from his gross pay:

Net Pay:

Gross pay = $1,930

Total deductions = $309.74

Net pay = $1,930 - $309.74 = $1,620.26

Therefore, Scott Salman's net pay after subtracting all of his deductions is $1,620.26.

Answer: Let's denote the length, width, and height of the cuboid as l, w, and h, respectively. We know that the shaded face is a square, which means that two of its dimensions are the same. Without loss of generality, let's assume that the dimensions of the square face are l and w.

Since the volume of the cuboid is 4900 cm³, we have:

lwh = 4900

Substituting l = 25 - w (since the length of the cuboid is 25 cm) and simplifying, we get:

(25 - w)w h = 4900

Now, we use the fact that the shaded face is a square. Since two of its dimensions are the same, we have:

l = w

Substituting this into the equation above, we get:

(25 - l)l h = 4900

Simplifying further, we have:

25l^2 - 4900 = 0

Solving for l using the quadratic formula, we get:

l = 14 or -14/5

Since the length of the cuboid cannot be negative, we have l = 14. Therefore, the length of one side of the square face is 14 cm.

What is the example polygon?

A polygon is any two-dimensional shape formed by straight lines. Triangles, hexagons, pentagons, and quadrilaterals are examples of polygons.

                               Polygons are flat two-dimensional shapes with straight sides that are completely closed. The sides should be straight, not curved. However, polygons can have any number of sides. The word polygon comes from the Greek word "polgonos". 

This figure is called a pentagon and has the shape of a trapezoid.

To find its area, we can calculate the area of the trapezoid, which is given by:

A = (b1 + b2)/2 * h

where b1 and b2 are the lengths of the parallel sides and h is the height.

In this case, the length of b1 is 43 meters and the length of b2 is 18 meters, and the height is 34 meters, so the area of the trapezoid is:

A = (43 + 16)/2 * 34 + (43 + 21) * 34

A = 1003 + 1088

A = 2091 square meters.

What is a series?

An n-arithmetic sequence is a sequence in which the difference d of successive terms is constant.

The general term of the arithmetic progression can be written using its first term [tex]a_1[/tex], tolerance [tex]d[/tex], and index [tex]n[/tex] as [tex]a_n=a_1+(n-1)d[/tex].

According to the alternating series test, if a sequence {b_n} satisfies the following three conditions:

[tex]b_n[/tex] is positive for all [tex]n[/tex].

[tex]b_n[/tex] is decreasing (i.e., [tex]b_n > = b_{n+1}[/tex] for all n).

[tex]\lim_{n \to \infty} b_n =0\\[/tex]

Then the alternating series [tex](-1)^n b_n[/tex] converges.

To apply the alternating series test to the sequence {a_n}, we first note that [tex]a_n = (-1)^{n+1}/n[/tex] satisfies condition 3, since [tex]\lim_{n \to \infty} \frac{1}{n} =0[/tex].

Next, we observe that [tex]a_n[/tex] is positive for n = 1, 3, 5, ... and negative for n = 2, 4, 6, ..., so [tex](-1)^n a_n = (-1)^{n+1}/n[/tex] is an alternating sequence.

Finally, we show that a_n is decreasing by considering the difference between successive terms,

[tex]a_{n+1} - a_n = (-1)^n/n - (-1)^{n+1}/(n+1)\\ = (-1)^{n} [(n+1)/(n(n+1))] \\= (-1)^{n}/n(n+1) < 0[/tex]
