The absolute value or modulus |x| of a real number x is the non-negative value of x without regard to its sign.

The absolute value is always a positive value and not a negative number. so those numbers are called absolute values.

It is represented as |a|, which defines the magnitude of any integer ‘a’.

It defines removing any negative sign in front of a number and thinking of all numbers as positive.

Absolute value is a term used in mathematics to indicate the distance of a point or number from the origin (zero point) of a number line or coordinate system.

When x itself is negative (x<0), then its absolute value is necessarily positive

A 1-U, 1-V graph is a special type of graph that has only one vertex of degree 1 (U) and one vertex of degree 2 (V). The edge connecting the two vertices is called the "bridge" of the graph.

Because the graph has only one vertex of degree 2, it forms a simple path (a straight line) between the two vertices. The vertex of degree 1 is a leaf, which means it is only connected to one vertex, and the vertex of degree 2 is the other end of the path. The path is a simple one, meaning it has no loops or multiple edges between the two vertices.

In a 1-U, 1-V graph, the vertex of degree 1 (U) can be thought of as the start of the path and the vertex of degree 2 (V) as the end of the path. Because there are no other edges or vertices in the graph, the path is the only structure in the graph and it's a straight line.

It's important to note that a 1-U, 1-V graph is a special case of a graph and it's not a general representation of all possible graphs. Most graphs have more than one vertex and multiple edges, making them more complex than a simple straight line.

The value of 7th decile is, 250.2.

The value of 35th percentile is, 100.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The donations are as follows,

⇒ 50, 50, 50, 100, 100, 100, 150, 150, 200, 250, 250, 300, 300, 400, 500.

Now, We find the values as;

a) The upper quartile is,

⇒ Qₐ = a/4 (n + 1)

Here, n = 15

So, We get;

⇒ Q₃ = 3/4 (15 + 1)

        = 3/4 × 16

        = 12

So, Q₃ is in 12th position.

So, The value of Q₃ = 300

The value of 7th decile is,

⇒ D₇ = 7/10 (15 + 1)

        = 7/10 × 16

        = 11.2

Here, 11.2 is between the position 11th and 12th position which are 250 and 300 respectively.

Then, We get;

⇒ 300 - 250 = 50

Hence, The value of D₇ = 250 + 0.2

                                     = 250.2

Now, The value of 35th percentile is,

⇒ Pₐ = a/100 (n + 1)

⇒ P₃₅ = 35/100 (15 + 1)

The area of inscribed regular hexagon is 6[tex]\sqrt{3\\[/tex] unit square using the properties of equilateral triangles which combined, form the hexagon.

In a circle, a regular hexagon can be inscribed with all the six vertices of hexagon touching the circumference of the circle. The center of the circle is the center of the hexagon itself.

Now, if we join the center with all the vertices of the hexagon, we see six equilateral triangles are formed. The other two sides of each triangle apart from the ones joining the vertices of hexagon, are radii of the circle and all the sides are equal in length. The attached image can be referred for better understanding.

To find the area of the hexagon, we need to find the area of single equilateral triangle and multiply it by 6, as six triangles make a regular hexagon.

Radius of the circle ([tex]r[/tex]) = 2 units

Area of a single equilateral triangle = [tex]\sqrt{3} /4[/tex] [tex]r^{2}[/tex]

Answer:

Since 21 and 22 are vertical angles, they are congruent. Therefore, m/1 = m22.

Using the equation m/1 = (17x + 1) we can find the measure of the angle m22.

m22 = (17x + 1)

Since ZK and ZL are complementary angles, the sum of their measures is 90 degrees.

mZK + mL = 90

Using the equations mZK = (3x + 3) and mL = (10x-4) and substituting them in the equation, we can find the measure of each angle.

3x + 3 + 10x - 4 = 90

13x - 1 = 90

13x = 91

x = 7

Therefore, mZK = (3x + 3) = (3(7) + 3) = 24 and mL = (10x-4) = (10(7) - 4) = 66

Step-by-step explanation:

Answer:

a. y = 2x - 6

To find the slope of the equation, we need to find the coefficient of x which is 2. So the slope of this equation is m=2

To find the y-intercept, we can substitute x = 0 into the equation:

y = 2(0) - 6

y = -6

So the y-intercept of this equation is b = -6

b. y = 1/2 * x + 12

To find the slope of the equation, we need to find the coefficient of x which is 1/2. So the slope of this equation is m=1/2

To find the y-intercept, we can substitute x = 0 into the equation:

y = 1/2(0) + 12

y = 12

So the y-intercept of this equation is b = 12

Therefore, the slope-intercept form of the equation is y = 2x - 6 and y = 1/2x + 12 respectively.

So, the equation to determine the number of months is 200 + 10x = 0 + 60x.

Let x be the number of months you can belong to each gym for it to cost the same at both places.

The equation to determine the number of months is:

200 + 10x = 0 + 60x

To solve for x, we can subtract 200 from both sides of the equation:

10x = -200

And finally, we divide both sides by 10:

x = -20

Therefore, you can belong to each gym for -20 months for it to cost the same at both places. But since month are positive numbers, x=-20 is not a solution. Therefore, the statement is not true, the cost will never be the same for both gyms.

Answer:

Step-by-step explanation:There are a total of 20 sweets in the bag (5 red + 6 blue + 9 yellow).

To find the probability that Sarah takes two sweets of the same color, we need to find the probability of her choosing a sweet of a specific color on her first pick and then the probability of her choosing another sweet of that same color on her second pick.

For example, if she chooses a red sweet on her first pick, the probability of that happening is 5/20, or 1/4. Then the probability of her choosing another red sweet on her second pick, given that she already picked one, is 4/20, or 2/10. Therefore the probability of her choosing two red sweets in a row is (1/4) * (2/10) = 1/20.

Similarly, the probability of her choosing two blue sweets in a row is (6/20) * (5/20) = 3/50.

The probability of her choosing two yellow sweets in a row is (9/20) * (8/20) = 9/100.

The probability of her choosing two sweets of the same color is the sum of the probability of her choosing two red sweets, two blue sweets, or two yellow sweets in a row.

P(Two same color) = 1/20 + 3/50 + 9/100 = 11/50

So, the probability of her choosing two sweets of the same color is 11/50.

This is a condition known as ankylosis, and it describes a situation in which two bones lose their contact with each other.

Ankylosis can result from a variety of causes, including trauma, infection, or degenerative joint diseases. In cases of trauma, the articulating surfaces of the bones can be damaged, leading to a complete absence of contact between the two bones. Similarly, if an infection is present, the cartilage and ligaments of the joint can be destroyed, leading to ankylosis.

Finally, in cases of degenerative joint diseases, such as arthritis, the joint's articulating surfaces can be damaged, leading to a complete loss of contact between the two bones.

The symptoms of ankylosis vary depending on the severity of the condition. In mild cases, the patient may experience stiffness, pain, and reduced range of motion in the joint. In more severe cases, the joint may become completely immobile, and the patient may have difficulty walking or performing other activities.
