As a result, the Last boxplot is the one that shows the distribution that is given and the highest value is 30 .

The mean of a dataset, often known as the arithmetic mean, is the sum of all values divided by the total number of values (as opposed to the geometric mean). This is the most often used indicator of central tendency and is frequently referred to as the "mean." This is obtained by dividing the number of values in the dataset by the sum of all the values. Calculations can be performed using either raw data or data that has been integrated into frequency tables. A number's average is referred to as its average. Simple math can be used to determine: After adding up all the digits, divide by the number of digits. the sum divided by the number.

The measure of BC is 9 units.

Now, According to the question:

The given data is:

Quadrilateral ABCD is similar to Quadrilateral WXYZ.

AB =15 WX =25 XY =15 and YZ =20

To find the measure of BC.

We know that the corresponding sides of similar figures are proportional.

It is given that Quadrilateral ABCD is similar to Quadrilateral WXYZ. It means their corresponding sides are proportional.

[tex]\frac{AB}{WX}=\frac{BC}{XY}=\frac{CD}{YZ}=\frac{AD}{WZ}[/tex]

Now,

[tex]\frac{AB}{WX}=\frac{BC}{XY}[/tex]

After substituting the given values, we get

Quadratic equation will have 2 solution

Common quadratic equation as follows :

[tex]f(x) = ax^{2} + b(x) + c[/tex]

where :

a is the coefficient of [tex]x^{2}[/tex]

b is the coefficient of x

c is the constant term

To solve this equation there are several ways to do. One of the way is by factor.

For example :

[tex]x^{2} +7x + 10 = 0[/tex]

From above equation we search for factor. Assume they are a and b.

a. If a x b, the result will be 10

b. If a + b , the result will be 7

As we know that factor of 10 is 1, 2, 5, 10.

The best answer for those equation will be a = 2 and b = 5

[tex]x^{2} + 7x +10 = 0[/tex]

( x + 5 )( x + 2 ) = 0

x = -5 or x = -2

The solutions of the equation x² + 6x - 5 = 0 are m = -7 and n = 4.

An equation is an expression that states the equality of two mathematical quantities. It usually involves a set of mathematical symbols, such as an equal sign, numbers, and operators, which represent the relationship between the two sides of the equation. Equations are used to solve a variety of mathematical problems, ranging from simple equations to complex systems of equations.

We can solve this equation by using the Quadratic Formula.
The Quadratic Formula states that x = (-b ± √(b² - 4ac))/(2a).
In this equation, a = 1, b = 6, and c = -5.
Therefore, x = (-6 ± √(6² - 4(1)(-5))/(2(1))
x = (-6 ± √36 + 20)/2
x = (-6 ± √56)/2
x = (-6 ± √7(8))/2
x = (-6 ± 8)/2
x = (m = -14/2) + (n = 8/2)
Therefore, the solutions of the equation x² + 6x - 5 = 0 are m = -7 and n = 4.

The binomial that completes the factorization S³-1=( )(s²+s+1) is (S - 1).

A polynomial called a binomial has only terms. As an illustration, x + 2 is a binomial, where x and 2 are two distinct terms. Additionally, in this case, x's exponent, coefficient, and constant are all equal to 1.

A binomial is an algebraic expression with two terms that contains a variable, a coefficient, exponents, and a constant. The binomial polynomial x2 + 4x is another illustration. 

Given that

S³-1=( )(s²+s+1) complete the factorization by finding the correct binomial

But this expression follows difference of cubes and factors as

a³ - b³ = (a - b)(a² + ab + b²)

Time is always x, the independent variable.

Distance, money, etc. is always y, the dependent variable, when dealing with time.

Start with the ratio of 6:30.

If you travel 6 miles in thirty minutes, how many do you have in one?

Simplify it like this: [tex]\frac{6}{30} :\frac{30}{30}[/tex] [tex]= \frac{1}{5}: \frac{1}{1}[/tex]

The polygon with vertices A(11, 3), (3, -11), C(-13, -9) and D(-5, 9) is a rhombus

The vertices of a polygon are the points where the sides of the polygon meet. A polygon is a closed shape that is made up of a finite number of straight line segments. The number of sides in a polygon is called its order or its degree.

The vertices of a polygon can be used to identify the shape of the polygon, for example a triangle with vertices (2,3), (4,5) and (6,7) are different from triangle with vertices (3,4), (5,6) and (7,8)

In addition, the vertices can be used to find the lengths of the sides of the polygon and to calculate its area and perimeter. Vertices can also be used to indicate the relative position of a polygon to other shapes or figures.

It's worth noting that the term "vertex" is also used to refer to the top of a pyramid or cone and the peak of a mountain. In these cases, it refers to the highest point of the object.

In this problem, the vertices A(11, 3), (3, -11), C(-13, -9) and D(-5, 9) when plotted on a graphing calculator shows that the two opposite sides are not equal to one another.

The shape with the vertices is a rhombus.

The probability that they read both newspapers will be 9/40.

What is probability?

Probability denotes the likelihood of something happening. It is a mathematical discipline that deals with the occurrence of a random event. The value ranges from zero to one. Probability has been introduced in mathematics to predict the likelihood of occurrences occurring. Probability is defined as the degree to which something is likely to occur. This is the fundamental probability theory, which is also utilised in probability distribution. To determine the likelihood of a particular event occurring, we must first determine the total number of possibilities.

Now,

3. 1 1/6 + 2 5/6 = 3 1/6 cups of milk

Tyrone started out with 1 1/6 cup of milk. This could have been used for any number of things, such as cereal or baking. He then used 1 1/6 cup of this milk to make hot chocolate. After using the milk, Tyrone decided to buy 2 5/6 cups of milk from the store. This was most likely to make up for the milk he had used and to have enough for future use.

There are infinitely many possible solutions to a two-variable linear equation. Every point  which is a straight line, represents a solution to a linear equation with two variables.

In algebra, multiple equations are referred to as simultaneous equations or systems of equations because they must be solved simultaneously (the solution must satisfy each system of equations). For a system to have a singular solution, there must be an equal number of unknowns and equations. When there are enough data to construct equations from multiple unknowns, systems of equations are used to solve problems. When there are n unknowns, we typically require sufficient knowledge to formulate an equation for each one.

Thus, a system of linear equations with two variables has infinitely many  solutions.

Answer:

To find the new price of the bed sheets, we can calculate the amount of discount first and then subtract it from the original price.

The bed sheets were on sale 25% off, so the amount of discount is:

$36 x 25/100 = $9

To find the new price of the bed sheets, we can now subtract the discount from the original price:

$36 - $9 = $27

So the new price of the bed sheets is $27.

Answer:

$36 * 0.75 = $27. That is the answer.

If 1.00 is 100 percent, subtract 0.25 or 25 percent from that to get 0.75 or 75 percent as the value which is left then multiply the original price, $36 to get the equation and answer above.

The finance charge after the purchases and payment for a single billing period is $12.38.

The finance charge is the multiplication of the average daily balance and the monthly periodic rate.

To calculate the finance charge for a single billing period, we need to determine the average daily balance and then multiply that by the daily rate and the number of days in the billing period.

Here's the calculation:

Purchase 1: $100

Purchase 2: $200

Payment: $150

Average daily balance: (100 + 200) / 2 = $150

Daily rate: 15.5% / 365 days = 0.0425%
