The perimeter of a shape is the measurement around its edge and it is 101.36 in.

We must sum up the lengths of the quadrilateral four sides to determine its perimeter. Since there are two of each side measurement, it is easy to accomplish this by simply adding the length and width and multiplying the result by two.

Perimeter of given shape = 18 + 27 +27 + perimeter of the arc

the perimeter of the arc = Perimeter of the semicircle = [tex]\pi r[/tex]

Therefore the perimeter of the shape = 72 + 3.14 * 9 = 101.36 in.

The true statement about effect size is: The effect size is the extent to which the null or statistical hypothesis is false. Effect size is a measure used in research studies to quantify the magnitude of the difference between groups or the strength of an association between variables.

It helps determine the practical significance of the research findings, as opposed to the statistical significance.
When the effect size is small, detecting it is not necessarily easier, and a larger sample size may be required to achieve adequate statistical power. A larger effect size, on the other hand, might be easier to detect and might require a smaller sample size.
There is not just one type of effect size measure used in research studies. There are various measures of effect size, such as Cohen's d, Pearson's correlation coefficient (r), and odds ratio (OR), among others. Each type of effect size is suitable for different research designs and data types.

Choosing the appropriate effect size measure depends on the research question, the design of the study, and the type of data being analyzed.

To increase the value of the expression 1/3A-B^2, increasing A and keeping B constant will cause the expression's value to increase.

This is because the expression has a linear term of A and a quadratic term of B^2. Increasing A will result in a larger linear term, which will increase the value of the expression. None of the other options will necessarily increase the value of the expression. Keeping AAAA constant and decreasing BBBB or decreasing A and keeping B constant will both cause the value of the expression to decrease while keeping AAAA constant and increasing BBBB will only increase the quadratic term of the expression and may or may not result in an overall increase depending on the values of A and B.

If a simple random of size n is drawn from a population, then the 95% confidence-interval about "μ", if the sample size "n" is 23 is (101.68 , 110.32).

The population from which a simple random of size "n" is drawn is normally distributed,

We have to construct "95% confidence-interval" when n = 23,

So, c = 0.95, n = 23,

⇒ degree of freedom(df) = 23 - 1 = 22,

from t-distribution table, the critical-value corresponding to c = 0.95 and df = 22 is t = 2.074,

the lower bound is = x' - (t×s)/√n = 106 - (2.074×10)/√23 = 101.68,

the upper bound is = x' + (t×s)/√n = 106 + (2.074×10)/√23 = 110.32,

Therefore, the required 95% confidence interval is (101.68 , 110.32).

the first five terms of the geometric sequence can be either [tex]{2, 6, 18, 54, 162} or {-2, 6, -18, 54, -162}.[/tex]

Assume that "a" is the first letter of the geometric sequence and "r" is the common ratio.

According to the problem statement, the second term is 6. Therefore, we have:

[tex]ar = 6 .....(1)[/tex]

Similarly, the fourth term is 54, which gives us:

[tex]ar^3 = 54 .....(2)[/tex]

We must first determine the values of "a" and "r" in the geometric sequence. The two equations mentioned above can be solved simultaneously to achieve this.

The result of dividing equation [tex](2)[/tex] by equation [tex](1)[/tex] is

[tex]r^2 = 9[/tex]

When we square the two sides, we obtain:

r = ±3

Now, using equation (1), we can find the value of "a" as follows:

[tex]ar = 6[/tex]

Substituting r = 3, we get:

[tex]3a = 6[/tex]

[tex]a = 2[/tex]

Substituting [tex]r = -3[/tex], we get:

[tex]-3a = 6[/tex]

[tex]a = -2[/tex]

Therefore, the first term of the geometric sequence is either  [tex]2[/tex] or [tex]-2[/tex]  , and the common ratio is 3 or -3.

If the first term is 2 and the common ratio is 3, then the first five terms of the geometric sequence are: [tex]2, 6, 18, 54, 162[/tex]

The first five terms of the geometric sequence are as follows, if the common ratio is three and the first term is two:

[tex]-2, 6, -18, 54, -162[/tex]

So, the first five terms of the geometric sequence can be either [tex]{2, 6, 18, 54, 162} or {-2, 6, -18, 54, -162}.[/tex]

10t + 4p ≤ 25 inequality shows the maximum number of tables and people Nathaniel can invite while staying within his budget.

What is inequality?

In mathematics, an inequality is a statement that two values or expressions are not equal, but rather that one is greater than or less than the other. An inequality is denoted by the symbols "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to).

Let the number of tables Nathaniel buys be represented by t, and the number of people he invites be represented by p.

Then, the total cost can be expressed as:

Cost = 100t + 40p

Since Nathaniel does not want to spend more than 250, we can set up the inequality:

100t + 40p ≤ 250

We can simplify this inequality by dividing both sides by 10:

10t + 4p ≤ 25

Step-by-step explanation:

The perimeter of the rectangle is 38 feet, the predicted perimeter is 26 feet, the area of the rectangle is 30 square feet, and the predicted area is also 30 square feet.

The formulas for the perimeter and area of a rectangle are:

Perimeter = 2(length + width)

Area = length x width

In these formulas, "length" refers to the longer side of the rectangle, and "width" refers to the shorter side of the rectangle. The perimeter is the total length of the sides of the rectangle, and the area is the amount of space inside the rectangle.

To find the perimeter of the rectangle, we simply add up the lengths of all four sides:

Perimeter = 10 feet + 3 feet + 6 feet + 6 feet + 4 feet + 9 feet

Perimeter = 38 feet

To predict the perimeter, we could use the formula for the perimeter of a rectangle, which is:

Predicted Perimeter = 2(length + width)

We can find the length and width of the rectangle by finding the longest and shortest sides:

Length = 10 feet

Width = 3 feet

Therefore, the predicted perimeter would be:

Predicted Perimeter = 2(10 feet + 3 feet)

Predicted Perimeter = 26 feet

To find the area of the rectangle, we multiply the length by the width:

Area = 10 feet × 3 feet

Area = 30 square feet

To predict the area, we could use the formula for the area of a rectangle, which is:

Predicted Area = length × width

Using the same values for length and width as before, the predicted area would be:

Predicted Area = 10 feet × 3 feet

Predicted Area = 30 square feet

Therefore, the perimeter of the rectangle is 38 feet, the predicted perimeter is 26 feet, the area of the rectangle is 30 square feet, and the predicted area is also 30 square feet.

The total number of possible three-digit numbers is not odd, does not contain 6, and has at least one repeated digit is 13,221,888.

To find the number of possible three-digit numbers we need to use the systematic approach method

Step 1:

we have to find the number of three-digit numbers that are not odd. Number of possible choices for the units digit (0, 2, 4, or 8)= 4

Number of possible choices for tens and hundreds of digits (0-9 excluding 6 = 9

the total number of three-digit numbers that are not odd is,

= 4 x 9 x 9

= 324.

Step 2:

Count the number of three-digit numbers that do not contain 6.

Number of possible choices for each digit (0-5, 7, 8, or 9) = 8

the total number of three-digit numbers that do not contain 6 is,

= 8 x 8 x 8

= 512.

Step 3:

Count the number of three-digit numbers that do not have distinct digits. The number of possible choices for the repeated digit and 9 choices for the other digit = 9

the total number of three-digit numbers that have a repeated digit is

= 9 x 9 = 81.

Step 4:

Find the intersection of the sets of numbers counted in Steps 1-3.

To do this, we multiply the number of choices in each set:

= 324 x 512 x 81

= 13,221,888.

Therefore, 13,221,888 possible three-digit numbers are not odd, do not contain 6, and have at least one repeated digit.

To draw the image of triangle △ABC under a dilation with center C and a scale factor of 2, we need to follow a few steps. Firstly, we need to draw the original triangle △ABC. Then, we need to draw a straight line from the center of dilation C to each vertex of the triangle. These lines will act as our guides for where the new vertices will be located.

Next, we need to use the scale factor of 2 to determine the distance between the original vertices and the new vertices. This means that we need to multiply the distance between each vertex and the center of dilation by 2. We can then plot the new vertices along the lines we drew in the previous step.

Finally, we can connect the new vertices to form the image of the triangle under the dilation. This image will be twice as large as the original triangle and will be located in the same direction as the lines we drew from the center of dilation to each vertex.

The polygon is translated five units to the right.

A translation does not alter the appearance of a shape; it merely shifts it up, down, or from side to side. A metamorphosis serves as an example of translation. A transformation is a method for changing a shape's size or placement. At each location, the shape is translated in the same direction by the same amount.

The polygon ABCD's vertices are provided to us as A (-1, -1); B (1, -5); C (5, -5) and D (3, -1)

Also, the vertices of second polygon A'B'C'D' are given as A' (4, -1); B' (6, -5); C' (10, -5) and D' (8, -1).

It is evident that neither polygon's y coordinates have changed.

A 5 increment is made to the x-coordinates.

It would take the faster computer 525/20 minutes to do the job on its own.

Let the rate of the faster computer be F and the rate of the slower computer be S. Since they can complete the job together in 15 minutes, we have:

F + S = 1/15

We also know that the slower computer takes 35 minutes to do the job on its own, so:

S = 1/35

Now, we can substitute the value of S into the first equation to solve for F:

F + 1/35 = 1/15

F = 1/15 - 1/35

F = (35 - 15) / (15 * 35)

F = 20 / 525

Therefore, the rate of the faster computer is 20/525. To find how long it takes the faster computer to do the job on its own, we take the reciprocal of this rate:

A horizontal compression is identified by a factor inside the function, affecting the input variable, while a vertical compression is identified by a factor outside the function, affecting the output variable.

When examining the formula of a function that is the result of multiple transformations, a horizontal compression can be identified by a factor that appears inside the function, affecting the input variable (typically x). For example, if the original function is f(x) and the horizontal compression is by a factor of 2, the function would be written as f(x/2), indicating that the input values are being compressed horizontally.

On the other hand, vertical compression can be identified by a factor that appears outside the function, affecting the output variable (typically y). For example, if the original function is f(x) and the vertical compression is by a factor of 1/2, the function would be written as (1/2)f(x), indicating that the output values are being compressed vertically.

The equation of the circle with center (5,5) containing the point (0,-2) is [tex](x - 5)^2 + (y - 5)^2 = 74[/tex]

The standard equation of a circle is given by: (x-h)2 + (y-k)2 = r2 Where (h,k) is the coordinates of center of the circle and r is the radius.

To determine the equation of the circle, we need to find the radius first. Since the center of the circle is (5,5), we can use the distance formula to find the distance between the center and the given point (0,-2):

[tex]distance = \sqrt{[(x2 - x1)^2 + (y2 - y1)^2]}\\distance = \sqrt{[(0 - 5)^2 + (-2 - 5)^2]}\\distance = \sqrt{[(-5)^2 + (-7)^2]}\\distance = \sqrt{[25 + 49]}\\distance = \sqrt{[74]}[/tex]

Therefore, the radius of the circle is sqrt[74].

Now, we can use the standard form of the equation of a circle to find the equation of the circle:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

where (h,k) is the center of the circle, and r is the radius.

Plugging in the values we have:

[tex](x - 5)^2 + (y - 5)^2 = (\sqrt{[74]})^2[/tex]

Simplifying the equation:

[tex](x - 5)^2 + (y - 5)^2 = 74[/tex]

Therefore, the equation of the circle with center (5,5) containing the point (0,-2) is [tex](x - 5)^2 + (y - 5)^2 = 74.[/tex]
