Step-by-step explanation:

Answer: 12 inches

Step-by-step explanation:

The 20 inches is the hypotenuse whereas 16 inches is the height of the triangle respectively.

So,

let keep the paper's length as x inches.

20² = 16² + x²

x² = 20² - 16²

x = [tex]\sqrt{20^{2}-16^{2} }[/tex]

x = 12

I am not sure if this is right because i have never done a sum in inches before but  I hope this helps sorry if it is not right.

The probability that the website has fewer than 8 million visitors in a single day is 0.2061 or 20.61%.Hence, option C is correct.

The traffic to the web site of Made by Charmz, LLC which sells customized mugs, follows a normal distribution,

with a mean of 8.5 million visitors per day and a standard deviation of 610,000 visitors per day.

The problem asks us to find the probability that the website has fewer than 8 million visitors in a single day.

Therefore, we need to find P(X < 8 million).

Using the Z-score formula, we have;

[tex]Z=\frac{X-\mu}{\sigma}[/tex]

Where X = 8 million, μ = 8.5 million and σ = 610,000.

Substituting the given values in the formula, we get:

[tex]Z=\frac{8-8.5}{0.61}=-0.8197[/tex]

Using a standard normal table, the probability corresponding to Z-score = -0.8197 is 0.2061.

Therefore, the probability that the website has fewer than 8 million visitors in a single day is 0.2061 or 20.61%.Hence, option C is correct.

With little knowledge of the square shape, we know that the area of the shaded region is (B) x² - 2y².

A square is a regular quadrilateral in Euclidean geometry, which means that it has four equal sides and four equal angles.

It can alternatively be explained as a rectangle with two neighboring sides that are of equal length.

As we previously stated, a square is nothing more than a rectangle with equally long neighboring sides.

The area of a rectangle is therefore expressed as Area = Length Breadth.

So, according to the given figure:
The area of the shaded region would be:

x² - y²

But as we know that 2 triangles make up 1 small square, so the formula can be molded as:

x² - 2y²

Therefore, with little knowledge of the square shape, we know that the area of the shaded region is (B) x² - 2y².

Open circle and move to the left.

Point E: (7, 3), Point F: (1, 3), Point G: (1, -2) and Point H: (7, -2) are the coordinates of each point.

To translate a point in the (x, y) coordinate plane, we add the translation distances to the x-coordinate and the y-coordinate of the point.

For each point in the quadrilateral EFGH, we can apply this translation as follows:

Point E: (4, 5) + (3, -2) = (7, 3)

Point F: (-2, 5) + (3, -2) = (1, 3)

Point G: (-2, 0) + (3, -2) = (1, -2)

Based on the Hypotenuse-Length Theorem of Congruence (HL), the values of x and y that will make both right triangles congruent are:

x = 8 and y = 4

Two triangles are said to be congruent if the three sides and three angles are equal in all directions.

Two right triangles are congruent to each other by the Hypotenuse-Length Congruence Theorem (HL) if the hypotenuse length and one leg of a right triangle are congruent to the hypotenuse length and leg of the other right triangle.

Thus, for both right triangles to be congruent, it means that their hypotenuse and one of their corresponding legs must be equal to each other.

Use this to create two equations and solve them to get the value of x and y.

Equal Hypotenuse:

    x + y = 3y

⇒ x +4 -4 = 3y -4

⇒ x = 3y -4              ------------------------ (1)

Equal legs:

x = y +4                    _______________ (2)

Find the value of y, by substituting x = (y + 4) into eqn. 1.

   y + 4 = 3y - 4

⇒ -2y = -8

⇒ y = 4

Find the value of x, by substituting y = 4 into eqn. 2.

   x = y + 4

⇒ x = 4 +4

⇒ x = 8

Therefore, based on the Hypotenuse-Length Theorem of Congruence (HL), the values of x and y that will make both right triangles congruent are: x = 8 and y = 4.

The domain of a function refers to the set of all values of the independent variable (usually denoted by x) for which the function is defined.

For the function f(x) = 2, the expression is defined for all real values of x. Therefore, the domain of f(x) is all real numbers.

If the function was f(x) = 2 / (x - 9), then the expression is undefined for x = 9. Therefore, the domain of f(x) would be all real numbers except 9.

If the function was f(x) = 2 / (x - 3)(x + 3), then the expression is undefined for x = 3 and x = -3. Therefore, the domain of f(x) would be all real numbers except 3 and -3.

If the function was f(x) = sqrt(2x - 5), then the expression is only defined for values of x that make the argument of the square root non-negative. Therefore, the domain of f(x) would be all real numbers such that 2x - 5 >= 0, which simplifies to x >= 5/2.

Therefore, without more information about the function, it is impossible to determine its domain.

Answer:

To find out how much more Joi paid than Adelyn for each fidget popper, we need to know how much Adelyn paid for each fidget popper.

If we assume that Adelyn bought the same set of fidget poppers as Joi at the regular price of $20 without tax, then we can calculate how much Adelyn paid for each fidget popper by dividing the total price by the number of fidget poppers in the set.

Let’s say that there are 10 fidget poppers in the set. Then, Adelyn paid $20 / 10 = $2 per fidget popper.

Joi bought the same set of fidget poppers at the regular price of $20 plus 8% sales tax. To find out how much Joi paid for each fidget popper, we can add the sales tax to the regular price and then divide by the number of fidget poppers in the set.

The sales tax is 8% of $20, which is $1.60. So, Joi paid a total of $20 + $1.60 = $21.60 for the set.

If there are 10 fidget poppers in the set, then Joi paid $21.60 / 10 = $2.16 per fidget popper.

To find out how much more Joi paid than Adelyn for each fidget popper, we can subtract Adelyn’s price per fidget popper from Joi’s price per fidget popper:

$2.16 - $2 = $0.16

Therefore, Joi paid $0.16 more than Adelyn for each fidget popper

Thus, the two factors of quadratic expressions found after factorization are 2 and 3.

Factorization is the technique of expressing a given statement as the product between two or more components. The sum of the greatest common factors of the integer coefficients and the same letters with the smallest powers yields the greatest common factor for two or more monomials.

Given quadratic expressions:

=  x² - 5x + 6

To factorize the expression, find the factors of 6 such that on addition it becomes -5.

= x² - 3x - 2x + 6

Taking x common from first two terms and -2 from last two terms.

= x(x -3) -2(x - 3)

Taking (x - 3) common.

= (x - 3)(x - 2)

x -3 = 0

x = 3

and, x - 2 = 0

x = 2

If repeats are forbidden, the provided letters u, v, w, x, y, and z can be used to create 8 lists of length 3, each of which has a w or u in the second entry.

We can apply the inclusion-exclusion concept to resolve this issue.

First, let's determine how many total lists of length three can be created using the provided letters without any limitations. There are six options for the first submission, five for the second (since it must be either w or u), and four for the third (since no characters can be repeated). Thus, there are a total of the following lists:

6 × 5 × 4 = 120

Next, let's count the number of lists of length 3 that do not have a w or u in the second entry. We have 6 choices for the first entry, 4 choices for the second entry (since we can't choose w or u), and 4 choices for the third entry (since we can't repeat any letters). Thus, the total number of such lists is:

6 × 4 × 4 = 96

Similarly, we can tally the number of lists of length 3 lacking a w or u in the first entry as well as the number of lists of length 3 lacking a w or u in either the first or second entry. Which are:

4 × 5 × 4 = 80 (no w or u in first entry)

4 × 4 × 4 = 64 (no w or u in first or second entry)

Finally, we can use the principle of inclusion-exclusion to count the number of lists that have a w or u in the second entry. This is:

120 - 96 - 80 + 64 = 8

In 1960, the percentage of black students attending integrated schools in the South was approximately 2%.

Brown v Board of Education was a landmark decision in 1954 that declared segregation in public schools unconstitutional. However, it took several years for this decision to be implemented in Southern states, and in 1960, only 2% of black students in the South attended integrated schools. This highlights the resistance to desegregation in Southern states and the slow pace of change. It also underscores the ongoing struggles for civil rights and the continued efforts to address systemic racism in education and other aspects of American society.

Option D is incorrect because it gives a value that is not consistent with the scatter plot and the line of fit. The correct answer is: The y-intercept is 40.98. The machine starts with 40.98 ounces of diet soda.

In the context of a graph, the y-intercept is the point where a straight line or curve intersects the y-axis. It is the value of the dependent variable (y) when the independent variable (x) is equal to zero. Mathematically, it is the value of y when x = 0 in the equation of the line or curve. The y-intercept is also known as the initial value or starting point of the graph. It is often denoted as (0, b), where b is the y-coordinate of the intercept point.

The y-intercept of the line of fit represents the starting point of the relationship between the two variables, in this case, the amount of diet soda in the machine and the time after the machine is filled. Therefore, the y-intercept value of 40.98 means that the machine starts with 40.98 ounces of diet soda when it is filled.

Option A is incorrect because the y-intercept is a starting value, and it does not represent a rate of change.

Option B is also incorrect because it suggests that the machine loses 4.8 fluid ounces of diet soda every hour, which is not what the y-intercept represents.
