Option C : (-4, 6) are the coordinates of B'.
What are meant by coordinates?
Coordinates are two integers (Cartesian coordinates) or often a letter and a number that identify a particular place on a grid known as a coordinate plane. A coordinate plane has four quadrants and two axes: the horizontal x-axis and the vertical y-axis (vertical).
Given T(ABCD) = (A'B'C'D') and A = (6, -8) , A' = (-2, 4)
If B = (4, -6) then let B' = (x, y)
now, x - 4 = -2 - 6
x = 4 - 2 - 6 = -4
and y - (-6) = 4 - (-8)
y + 6 = 4 + 8
y = 6
Therefore, B' = (-4, 6)

A sorting algorithm is defined as an algorithm that sorts the elements of a list. The most commonly used sequences are numerical sequence and lexicographical sequence, ascending or descending.
A sorting algorithm is used to reorder an array or list of elements according to an element comparison operator. Comparison operators are used to define a new order of elements in that data structure. Consider example, The above list of characters is sorted in ascending order by their value. That is, characters with lower values are placed before characters with higher values. It is important in real life because it supports the development of the scientific concept that things can be owned and organized into distinct groups (e.g. creatures, cars, weather types, etc.). We will now discuss some real-world examples of using sorting algorithms.
1) Your phone's contact list is sorted. This means that your data is organized in this way so you can easily access the contacts you want from your phone. That is, "I ordered."
2) Paper sorting : Imagine a teacher sorting students' work alphabetically by student name. This type of operation is similar to the functionality of sorting algorithms such as bucket sort. Sorting is more efficient process.
3) Traffic lights : Traffic lights are a good example of how algorithms are used in the real world around us. Next time you get stuck in a car at a red light, think about the algorithm that traffic lights run." Most traffic lights don't automatically switch between green, yellow, and red. This algorithm is a well-established turn-by-turn algorithm that directs traffic correctly. It's in order (it may not seem that way when you're sitting at a red light).

Consider the following ordered data. 10 13 13 14 15 15 16 17 18 Find the low, Q_1, median, Q_3, and high. low ________ Q_1 ___________ median _________ Q_3 ___________ high ___________ Find the interquartile range. _________
The low Q₁ is 13 and the median Q₃ is 16.5, the high is 18 and the interquartile range is 3.5
The interquartile range is a measure of dispersion that tells us how spread out the middle 50% of a dataset is. To calculate the IQR, we first need to find the quartiles of the dataset. Quartiles divide a dataset into four equal parts, with the first quartile (Q₁) representing the 25th percentile, the second quartile (Q₂) representing the 50th percentile (also known as the median), and the third quartile (Q₃) representing the 75th percentile.
To find the quartiles of the dataset {10, 13, 13, 14, 15, 15, 16, 17, 18}, we first need to order the data in ascending order:
10, 13, 13, 14, 15, 15, 16, 17, 18
The low is the smallest value in the dataset, which is 10.
To find Q₁, we need to find the value that is 25% of the way through the dataset. Since we have 9 values in our dataset, 25% of 9 is 2.25. This means that Q₁ lies between the 2nd and 3rd values in the dataset, which are both 13. To find the exact value of Q₁, we can take the average of these two values:
Q₁ = (13 + 13) / 2 = 13
The median is the middle value in the dataset, which is 15.
To find Q₃, we need to find the value that is 75% of the way through the dataset. 75% of 9 is 6.75, which means that Q₃ lies between the 6th and 7th values in the dataset, which are 16 and 17, respectively. To find the exact value of Q₃, we can take the average of these two values:
Q3 = (16 + 17) / 2 = 16.5
The high is the largest value in the dataset, which is 18.
Now that we have found the quartiles, we can calculate the IQR by subtracting Q1 from Q₃:
IQR = Q₃ - Q₁ = 16.5 - 13 = 3.5
Therefore, the interquartile range of the dataset {10, 13, 13, 14, 15, 15, 16, 17, 18} is 3.5. This tells us that the middle 50% of the dataset is relatively tightly clustered around the median, with values ranging from 13 to 16.5.

Triangle GHI has coordinates G(-5, -2), H(3, 8), and I(2, 1). If the triangle is translated 1 unit up, what are the coordinates of H'?
The coordinates of point H' will be: H'(3, 9)
What is Translation ?We know that a translation is basically a transformation that occurs when an object is moved from one place to another place.
The original object's dimensions, orientation, or shape are unaffected by translation.
Translating a point P(x, y) 1 unit up means we need to add to use P'(x, y+1), that is adding 1 unit to the y-coordinate of the point P'(x, y).
Now we have to translate the triangle 1 unit up. So, use the formula
P(x, y) → P'(x, y + 1)
Thus, the coordinates of point H' will be:
H( 3, 8) → H'( 3, 8+1) → H'(3, 9)
Therefore, the coordinates of point H' will be: A'(3, 9).

Can someone help and find the length of AC?
If AD = 12 and BD = 36 in the right triangle ABC with altitude BD was drawn to hypotenuse AC, then the length of AC is 12√82.
What is the similarity law for triangles?
It is defined as the law to prove that two triangles have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the complementary angles are congruent.
We can use the property of similar triangles to find the length of AC.
Since BD is an altitude of triangle ABC, we can write:
(AD)(DC) = (BD)²
Substituting the given values, we get:
12(DC) = 36²
Solving for DC, we get:
DC = (36)²/12 = 3 x 36 = 108
Now, using the Pythagorean theorem, we can write:
(AC)² = (AD)² + (DC)²
Substituting the given values, we get:
(AC)² = 12² + 108²
Simplifying and solving for AC, we get:
AC = √(12² + 108²) = √(12² x (1 + 9²)) = 12 x √(1 + 9²) = 12 x √(82)
Therefore, If AD = 12 and BD = 36 in right triangle ABC with altitude
BD was drawn to hypotenuse AC, then the length of AC is 12√82.

What is the angle bisector of an angle?
The angle bisector of an angle is a line or line segment that divides the angle into two equal parts, creating two smaller angles that are congruent (i.e., have the same measure). The angle bisector starts from the vertex of the angle and extends to the opposite side or ray of the angle, dividing the angle into two smaller angles that have the same number of degrees.
By the definition of the angle bisector of an angle, the angle bisector divides the angle in two equal measures.
As m∠AOB = 155°
m∠BOX = 1/2 * m∠AOB
m∠BOX = 1/2 * 155
m∠BOX = 77.5°
also m∠AOX = 77.5°

What is the domain of the function?
The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
The domain of the function f(x) = √(6-x) is the set of all real numbers x such that 6-x ≥ 0, which is x ≤ 6.
The domain of the function g(x) = x² - x is the set of all real numbers x, since there are no restrictions on the input.
To find the domain of the function f * g, we need to consider the values of x for which the expression f(x) * g(x) is defined.
We have:
f(x)g(x) = √(6-x)(x² - x)
The expression is defined only if both factors are defined.
For the first factor, √(6-x) to be defined, we need 6-x ≥ 0. This means that x ≤ 6.
For the second factor, x² - x to be defined, there are no restrictions on the input.
Therefore, the domain of f * g is the set of all real numbers x such that x ≤ 6.

The future value is 6,495,554.308.
What has compounded annually?
The interest charged on a loan or deposit is known as compound interest. It is the idea that we use the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal and cumulative interest. The main distinction between compound and simple interest is this.
Compound interest can be calculated in math in a variety of ways depending on the circumstances. To make the calculations simpler, we can use the compound interest formula. We need to know the amount and the principal in order to calculate compound interest. The distinction is between the amount and the principal.
Given that $12,000 is invested in a project at 7% for 9 years.
The formula of compound interest is
A = P(1+r/n)^nt
A = amount
P = principal
r = rate of interest
t = time
n = number of compound interest per annum
For the given problem:
P =12,000, r = 7%, t = 9, n = 365:

The probability that a randomly selected cat has no treatment and no fleas is 43/87.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Total number of cats = (cats sprayed with flea deterrent + cats with no treatment)
= (33+6 + 43+5)

we need to find the number of cats with no treatment and no fleas, and divide it by the total number of cats.
Now we can see that the number of cats with no treatment and no fleas is 43.
Therefore, the probability that a randomly selected cat has no treatment and no fleas is:
P(no treatment and no fleas) = number of cats with no treatment and no fleas / total number of cats
= 43 / 87

perfectly and 20% of the time it turns into a full toss. When Harry Brook faces a yorker, he hits it
for a boundary 20% of the time. When Harry Brook faces a full toss, he hits it for a boundary 90%
of the time. Haris Rauf is bowling the last ball of the innings to Harry Brook. Before running in to
bowl this last ball, Haris Rauf has decided to bowl a yorker, what is the probability that a boundary
will be scored of this last ball of the innings.
Answer:
To solve it, you need to use probability. Let me show you how.
We can use a tree diagram to represent the possible outcomes of the last ball. Here is the diagram:
```
Haris Rauf
/ \
yorker full toss
0.8 0.2
/ \ / \
boundary no boundary boundary no boundary
0.2 0.8 0.9 0.1
```
The probability of a boundary is the sum of the probabilities of the branches that end with a boundary. To find the probability of each branch, we multiply the probabilities along the branch. For example, the probability of a yorker and a boundary is 0.8 × 0.2 = 0.16.
So, the probability of a boundary is:
0.8 × 0.2 + 0.2 × 0.9 = 0.16 + 0.18 = 0.34
Therefore, the probability that a boundary will be scored of the last ball is 0.34 or 34%.

The probability of drawing an orange marble and then a green marble without replacement is (a) 1/15 .
The probability of drawing an orange marble on the first draw = 2/10 because there are 2 orange marbles out of total of 10 marbles .
After 1 orange marble is drawn, there are 9 marbles left in the box, of which 3 are green.
So, the probability of drawing a green marble on the second draw, given that an orange marble was drawn on the first draw, is 3/9.
⇒ P(orange, green) = P(orange) × P(green | orange was drawn)
⇒ P(orange, green) = (2/10) × (3/9) = 6/90 = 1/15 ;
Therefore , the value of P(Orange , Green) is = 1/15 .

if the ratio of two sample variances exceeds the critical value of f at a defined confidence level, then___
if the ratio of two sample variances exceeds the critical value of f at a defined confidence level, then the level of confidence also exceeds the critical level.
All tests that make use of the F-distribution are collectively referred to as "F Tests." The F-Test to Compare Two Variances is often what is meant when the term "F-Test" is used. However, a number of tests, including regression analysis, the Chow test, and the Scheffe test, use the f-statistic. If we are conducting an F-Test, we might employ a variety of technological tools. since doing an F-test manually while accounting for variations is a difficult and time-consuming operation.

find the size of angle x 164
Note that the size of angle x = 115°. This is a problem relating to the sum of angles in a circle. See the computation below.
What is the sum of angles in a circle?The sum of angles in a circle is always equal to 360 degrees or 2π radians.
This means that the sum of the measures of the angles formed by any number of rays or line segments that meet at a common point, or vertex, and whose endpoints lie on the circle, will always add up to 360 degrees or 2π radians. This property is often used in geometry and trigonometry to solve problems involving circles and angles.
With regard to the above problem,
We are given three angles in a circle named as follows:
a) 81°
b) 164°
c) x
The above rule state that
81 + 164 + x = 360°
thus, x = 360 - 81 - 164
x = 360 -245
x = 115°
Thus the value of ∠x is 115°

A city's population is currently 365,000. If the population doubles every 24 years, what will the population be 96 years from now?
Answer:
5,840,000
Step-by-step explanation:
Let P be the population after x years. The population after 24 years is 2P. So, we have:
P = 365,000 * 2^(x/24)
To find the population after 96 years, we plug in x = 96:
P = 365,000 * 2^(96/24) = 365,000 * 2^4 = 365,000 * 16 = 5,840,000
So, the population of the city will be 5,840,000 after 96 years.

Look at the picture of a scaffold used to support construction workers. The height of the scaffold can be changed by adjusting two slanting rods, one of which, labeled PR, is shown:
A support structure is shown in which a right triangle PQR is formed with the right angle at Q. The length of PQ is shown as 14 feet, and the length of QR is shown as 9 feet.
Part A: What is the approximate length of rod PR? Round your answer to the nearest hundredth. Explain how you found your answer stating the theorem you used. Show all your work. (5 points)
Part B: The length of rod PR is adjusted to 18 feet. If width PQ remains the same, what is the approximate new height QR of the scaffold? Round your answer to the nearest hundredth. Show all your work. (5 points)
Solving the provided question, we can say that By, Pythagorean theorem PR = √277 and b = 11.31
What is Pythagorean theorem?The Pythagοrean Theorem, sometimes known as the Pythagοrean Theorem, is the basic Euclidean geοmetry relationship between a right triangle's three sides. Accοrding to this rule, the area of a square with the hypotenuse side equals the sum οf the areas of squares with the other twο sides. The Pythagοrean Theorem, often knοwn as the generic algebraic nοtation a² + b² = c², states that the square that crοsses the hypotenuse οf a right triangle οpposite the right angle equals the sum of the squares that span the sides of a right triangle.
By, Pythagοrean theorem
PR² = PQ² + QR²
PR² = 14² + 9²
PR² = 196 + 81
PR = √277
Again by Pythagorean theorem
c² - a² = b²
18² - 14² = b²
b² = 324 - 196
b = √128
b = 11.31
