Your

fixed expenses
The amount allowed for housing and expenses is $2023.73.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Gross pay = $2759
Deduction:
7.65%
= 7.65/100 x 2759
= $211.06
12%
= 12/100 x 2759
= $331.08
7%
= 7/100 x 2759
= $193.13
The remaining amount.
= 2759 - 211.06 - 331.08 - 193.13
= $2023.73
Thus,
The amount allowed is $2023.73.

Suppose that the population of a certain town is made of 45% men and 55% women. Of the men, 40% wear glasses, and of the women 20% wear glasses. Given that a person chosen at random from this town wears glasses, what is the probability that the person is a woman?
The probability that the person is a woman is 40%.
what is the probability that the person is a woman?P(woman | glasses) = (20% * 55%) / (40% * 45% + 20% * 55%) = 0.55There is a 50% probability that a sperm will fertilize a boy and a 50% chance that a sperm will fertilize a female ovum each time.The probability that a randomly chosen person in this town wears glasses is equal to the sum of the probability of a man wearing glasses and the probability of a woman wearing glasses.P(Glasses) = P(M ∩ G) + P(W ∩ G)
P(Glasses) = 0.45 × 0.40 + 0.55 × 0.20
P(Glasses) = 0.27
The probability that the randomly chosen person is a woman is equal to the probability of a woman wearing glasses divided by the probability of a person wearing glasses.P(Woman) = P(W ∩ G) / P(Glasses)
P(Woman) = 0.55 × 0.20 / 0.27
P(Woman) = 0.44

Answer:
The exact value of x so that the greatest possible amount of light is emitted is 8.96ft.
What is the perimeter of a semicircle?
The perimeter of a semicircle is half that of a circle, that is [tex]\pi r[/tex], where r is the radius of the circle.
Step-by-step explanation:
Given the width of the rectangle is x, let the height of the rectangle be y.
The radius of the semicircle is x/2.
The perimeter of the window is equal to [tex]2y+x+\pi \frac{x}{2} =32[/tex].
The area of the window is [tex]xy+\frac{1}{2}(\pi )(\frac{x}{2})^2=xy+\frac{\pi x^2}{8}[/tex].
We can insert into the formula for the area to obtain the area in terms of only x by solving the equation for the perimeter of y in terms of x.
[tex]2y=32-(1+\frac{\pi }{2} )x=32-(\frac{2+\pi }{2} )x\\y=16-(\frac{2+\pi }{4} )x[/tex].
Now the area of the window in terms of only x is:
Area=[tex]16x-(\frac{2+\pi }{4} )x^2+\frac{\pi x^2}{8}[/tex].
Since it is given in the question that maximum light should be admiitted, we will differentiate the Area and set it to 0.
[tex]16-2(\frac{2+\pi }{4} )x+\frac{\pi x}{4}=0\\ 16=x(1+\frac{\pi }{4})\\ x=\frac{16}{1+\frac{\pi }{4}} \\x=8.96ft[/tex].

The data file contains the midterm and final scores of 32 students in a statistics course. To estimate a student's final score as a function of their midterm score, we used a regression analysis. The regression equation was Final = 27.5818 + 0.6774 Midterm. This equation can be used to predict the final score of a student based on their midterm score. The standard error of the estimate was 14.947. This indicates the accuracy of the estimated final score. The coefficient of determination was 0.5297, which means that 53% of the sample variation in final grades is explained by the regression equation. This tells us that the regression equation is a relatively good predictor of a student's final score.
Given:
Midterm Score = x
Final Score = y
Regression Equation: y = 27.5818 + 0.6774x
Standard Error of the Estimate = 14.947
Coefficient of Determination = 0.5297
Calculating Final Score:
y = 27.5818 + 0.6774x
y = 27.5818 + 0.6774(x)
y = 27.5818 + 0.6774(x)
y = 27.5818 + 0.6774(x)

And △RVS is not equilateral.
Then the explanation for this one is written as,
Let us assume temporarily that △RST is equilateral.
And we have given that △RVT and SVT are equilateral, then the sides of △RVT, SVT, and RST are congruent.

The length of the vector v is approximately 4.24. A vector is a mathematical object that has both magnitude and direction
Vectors are commonly used in physics, engineering, and other fields to represent quantities that have both magnitude and direction, such as velocity, acceleration, and force. They are also important in linear algebra, where they can be used to represent lines and planes in space, and to solve systems of linear equations.
The vector v can be expressed in component form as v = <2-5, 10-7> = <-3, 3>.
To express the vector v as a linear combination of the unit vectors i and j, we can write it as v = (-3)i + 3j.

A one degree inequation is known as linear inequation.
The given linear inequation is
[tex]y \leq \frac{1}{2}x -5[/tex]
Here equality is maintained. So the line is a solid line
Now, (0, 0) does not satisfy the inequality.
So the solution is below the line
When graphing the inequality above, we will draw a solid line and the solution lies below the line

1. A taxi service charges a $ 1.95 flat rate plus $ 0.55 per mile. Jason only has $ 12 to spend on a ride. Which graph best represents the number of miles Jason can afford to travel?
Answer:
B
Step-by-step explanation:
Subtract $1.95 from $12 to account for the flat rate that Jason must pay, then divide that by 0.55, or the per mile charge. The answer, or the highest amount of miles he can go with $12, is 18.27272727. The answer that best represents the number of miles he can go is B because he can go up to 18 miles, including 18 miles, hence the closed circle.
Find the length and width of a rectangle that has the given area and a minimum perimeter.
Area: 5A square cm
Find length and width of a rectangle with minimum perimeter that has an area of 5A square cm
length=
width=
By taking minimum perimeter the value of length and width will both be [tex]\sqrt{5A}[/tex].
What is perimeter?Perimeter is basically the sum of all sides of a figure.
How to calculate perimeter of rectangle?The perimeter of a rectangle is 2l + 2w where l = length and w = width of rectangle.
Since the perimeter needed in this question is minimum, the figure must be a square and not a rectangle. For a square, area = a^2
5A = a^2
a = l = w = [tex]\sqrt{5A}[/tex]
Hence, both the length and width are equal to [tex]\sqrt{5A}[/tex].

The value of x from the triangle is x = 31
What are similar triangles?
If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be ABC
The measure of side AB = 14.5
The measure of side BC = 15.5
Let the second triangle be XYZ
The measure of side XY = 29
The measure of side YZ = x
Now , if the triangle ABC is similar to triangle XYZ , then the corresponding sides of the triangles will be equal in ratio
So , the equation will be
XY / AB = YZ / BC
Substituting the values in the equation , we get
29 / 14.5 = x / 15.5
On simplifying the equation , we get
x/15.5 = 2
Multiply by 15.5 on both sides of the equation , we get
x = 2 x 15.5
x = 31
Therefore , the value of x is 31
Hence , the value of x of side YZ is 31

For a hypothesis test comparing two independent population means, the combined degrees of freedom are 56. Which of the following statements about the two sample sizes cannot be true? Assume the population standard deviations are unknown but equal Multiple Choice O m = 29, n2 - 29 O m-27; 12 - 29 O m = 26; * 32 28O n2 = 30
Option B [tex]n_{1} = 27 ,n_{2} = 29[/tex] are the two sample sizes cannot be true.
HYPOTHESIS TEST
Hypothesis testing in statistics is the process of putting a population parameter assumption to the test. The analyst will select a method based on the type of data used and the goal of the research. Hypothesis testing is a method used to determine whether a hypothesis is tenable by using sample data.Given that:
The degree of freedom for the test of two independent population means is 56.
Degrees of freedom for two independent populations are well known.
[tex]n_{1} + n_{2} - 2[/tex]
[tex]n_{1} + n_{2} - 2[/tex] = 56
[tex]n_{1} + n_{2}[/tex] = 54
Total sample sizes = 54
Option B ( [tex]n_{1} = 27 ,n_{2} = 29[/tex] ) cannot be true.
