What is basic algebra ?Algebra is one of the areas of mathematics where mathematical expressions can be used to represent situations or problems. In order for a mathematical statement to make sense, it must have mathematical operations like addition, subtraction, multiplication, and division as well as variables like x, y, and z. Every branch of mathematics, including calculus, trigonometry, and coordinate geometry, uses algebra. The equation 2x + 4 = 8 is a simple algebraic formula.Mathematical branch known as algebra deals with symbols and arithmetic operations on them. These symbols are referred to be variables since they lack set values. We frequently observe specific values that change in our day-to-day situations. However, there is a continuing need to depict these shifting values. These values are frequently represented in algebra by symbols, which are known as variables, such as x, y, z, p, or q. In order to determine the values, additional arithmetic operations such as addition, subtraction, multiplication, and division are performed on these symbols.

Option D is correct
What is function and graph of a function?
A function from A to B is a rule that assigns to each element of A a unique element of B.
Set of all points of the form (x, f(x)) is called graph of a function.
Here,
There is a hollow circle on y = 5 line and the function continues upwards
Also,
[tex]=\lim_{x \to 1} y(x)\\= \lim_{x \to 1} x^2 + 4\\= 1^2 + 4\\=5[/tex]
Now, there is a solid circle on y = -1 line and the function continues downward
So there is an equality on x = 1 downward
Now f(1) = [tex]1^3-2[/tex]
= -1
So the appropriate graph will be
[tex]\left \{ {x^3 - 2, {x \leq 1} \atop x^2+1, {x > 1}} \right.[/tex]

A.) 33 1/3%
B.) 37 1/2%
C.) 40%
D.) 62 1/2%
E.) 75%
As per given data of end of the season , ratio of teams win to losses is 3:5 and no ties, then percentage of game win by team is equal 37 1/2%.
As given in the question,
For the given dat of end of season,
Ratio of teams win to losses is equal to 3:5
Let x be the percentage of game
As per given ratio we have,
3x+ 5x =100%
⇒ 8x = 100
⇒x =100/ 8
⇒ x= 12.5
Percentage of winning the game by team = 3x
= 3(12.5)
= 37.5%
= 37 1/2%
Therefore, for given data of end of the season , ratio of teams win to losses is 3:5 and no ties, then percentage of game win by team is equal 37 1/2%.

It is True to state that Arcs AB, BC, CD, DE, EF, FA in the circumscribed hexagon are all equal. See the explanation below.
What is a regular hexagon?In geometry, a hexagon is a six-sided polygon. A regular hexagon is one in which the lengths of all the sides and the measurements of all the angles are identical. The sides of a regular hexagon are therefore equivalent.
Allow point P to be the hexagon's and circle's center.
The dimension of arc AB is the same as the measure of central angle APB, which are both 360/6 = 60 degrees. This also applies to the other arc measurements. The whole 360-degree circle is divided into six equal parts, each measuring 60 degrees.

What is the area of trapezoid ABCD? Enter your answer as a decimal or whole number in the box. Do not round at any steps.
The area of the trapezoid is given as 100. See the explanation for the same below.
What is a Trapezoid?A trapezoid is a quadrilateral with at least one set of parallel sides in American and Canadian English. A trapezoid is known as a trapezium in British and other varieties of English.
To find the length of each side of the trapezoid, you need to use the distance formula.
AB = (-1,5) and (3,2)
BC = (3,2) and (0,-2)
CD = (0,-2) and (-13, -11)
AD or DA = (-1,5) and(-13, -11)
Now, just use the distance formula for each line.
The Distance Formula is given as: d=√((x2 – x1)² + (y2 – y1)²).
Distance AB = √((3 – (-1))² + (2 – 5)²).
= √(4)² + (-3)²
= √(16+9)
= √25
AB = 5
lets us repeat this for the other section we will get:
Doing so gives us for all the points:
AB = 5
BC = 5
CD = 15.811388300842
DA or AD = 20
Note that:
The height is AD, the first base is AB and the second base is BC. We can plug the values for these sides into the trapezoid area formula, which is:
A = (base 1 + base 2) / 2 x height.
A = (5+5)/2 x 20
A = 5 x 20
A = 100.

A reflection is referred to as a twist in geometry. A reflection is the mirror image of shape . A line, called the line of reflection, will agree an image to reflect without change it. When all of the points in a figure are evenly spaced apart from one another, the two figures are said to reflect each other. The reflected picture should have the same size and shape as the original, but it faces the opposite way. Changes in position during contemplation may also result in translation. Pre-image and image are terms used to refer to the same thing in this context. ABC and A'B'C are used to represent the pre-image and image, respectively.

a refrigerator was originally priced at $250. it was then put on sale for 20% of. what is the number of dollars in the final price of the refrigerator if an additional 15% is taken off from the sale price?
The final price of the refrigerator after the additional 15% discount is $170
Given
The original sale price of the refrigerator = was $250
Given a 20 % discount on the original price, the new sale price would be as follows
Sale price = original price - Discount
= [tex]250-(\frac{20}{100} )250[/tex]
Sale price = $200
After this an additional 15% discount is given on new sale price.
So again deducting the discount from the sale price we get,
Sale price = 200 - discount(15%)
= [tex]200-(\frac{15}{100} )200[/tex]
Sale price = 170

solve for X on each of them and find the measurements of the angles
The unknown angles are as follows:
∠1 = 67.9°, ∠2 = 22.08°∠1 = 129°, ∠2 = 51°∠1 = 13.5°, ∠2 = 13.5°How to solve angles?complementary angles are angles that sum up to 90 degrees.
in other words, When two angles add to 90°, we say they "Complement" each other.
Therefore,
9x + 2x + 7 = 90
11x = 90 - 7
11x = 83
x = 83 / 11
x = 7.54
Therefore,
∠1 = 9(7.54) = 67.9°
∠2 = 2(7.54) + 7 = 22.08°
Supplementary angles are angles that sum up to 180 degrees.
Therefore,
3x + 8 + 9x = 180
12x + 8 = 180
12x = 180 - 8
12x = 172
x = 172 / 12
x = 14.3
Hence,
∠1 = 9(14.3) = 129°
∠2 = 180 - 129 = 51°
Vertically opposite angles share the same vertex. Vertically opposite angles are equal.
Therefore,
9x = 3x + 9
9x - 3x = 9
6x = 9
x = 9 / 6
x = 3 / 2
x = 1.5
Therefore,
∠1 = 9(1.5) = 13.5°

Assume that when human resource managers are randomly selected, 64% say job applicants should follow up within
two weeks. If 7 human resource managers are randomly selected, find the probability that exactly 4 of them say job
applicants should follow up within two weeks.
The probability is.
(Round to four decimal places as needed.)
BCEXIS
Using the binomial distribution, there is a 0.2740 = 27.40% probability that exactly 4 of them say job applicants should follow up within two weeks.
For each manager, there are only two possible outcomes, either they say that job applicants should follow up within two weeks, or they do not say it. The opinion of a manger is independent of the opinion of any other manager, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula for the probability of x successes is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are given by:
n is the number of trials of the experiment.p is the probability of a success on a single trial of the experiment.In the context of this problem, the parameters are given as follows:
n = 7, p = 0.64.
The probability of exactly 4 saying that applicants should follow up within two weeks is P(X = 4), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 4) = C_{7,4}.(0.64)^{4}.(0.36)^{3} = 0.2740[/tex]

You use floor tiles to help you learn a new dance move. You move 2 tiles right and 3 tiles up. Then you move 1 tile left and 1 tile down. Rewrite the composition as a single translation.
The given composition as a single translation is (x,y)→(x+1,y+2) .
In the question,
two translation are given , we have to write the composition of two translation in a single translation ,
we choose arbitrary points (x,y) in the tile , and find the horizontal and vertical shift in the coordinates of point after both translations .
let A(x,y) be an arbitrary point in the tile
So , by the first translation
"move 2 tiles right and 3 tiles up" ,
after first translation, the coordinates are A'(x+2,y+3)
The second translation "you move 1 tile left and 1 tile down" , will map A'(x+2,y+3) to
A"(x+2-1 , y+3-1)
= A"(x+1 , y+2)
Therefore , the single translation rule for the composition is (x,y)→(x+1,y+2) .
