Answer:
15x² - 64x + 64
Step-by-step explanation:
To find the area of shaded region, we will first find the area of the whole shape then subtract the area of the white region.
The area of a square is calculated by multiplying the one side with itself:(4x-8)×(4x-8) = 16x² - 64x - 64 is the area of the whole shape
x*x = x²
Now subtract x² from the whole area16x² - 64x - 64 - x² = 15x² - 64x - 64

find the following probabilities related to odds. step 1 of 2 : if the odds in favor of a horse winning a race is 8:9 , what is the probability of the horse winning the race? express your answer as a simplified fraction.
Answer: The odds in favor of a horse winning a race are given as 8:9, which means that the probability of the horse winning is 8/(8+9) = 8/17. Therefore, the probability of the horse winning the race is 8/17.
Step-by-step explanation:
The probability of the horse winning the race is 8/17.
The odds in favor of a horse winning a race is 8:9. To find: The probability of the horse winning the race. The odds are defined as: The odds in favor of an event = Number of ways an event can occur : Number of ways the event cannot occur.
Here, the odds in favor of a horse winning a race = 8 : 9. That means, the horse can win in 8 ways and lose in 9 ways. Therefore, the probability of the horse winning the race can be calculated as follows:
Probability of horse winning the race = Number of ways the horse can win / Total number of possible outcomes
= 8 / (8 + 9) [As total outcomes = winning outcomes + losing outcomes]
= 8 / 17
Therefore, the probability of the horse winning the race is 8/17.

If FG = 10 and GH=7 what is EG
Therefore , the solution of the given problem of triangle comes out to be EG = 23.14.
What is triangle?A triangle is a hexagon because it has two or more extra polygon sections. Its form is a simple rectangular one. A and B are the only 2 different edges of a form that can set it apart from a regular triangular. When bounds are still not precisely collinear, Euclidean geometry produces a single section rather than a full cube. Three edges and three angles make up a triangle.
Here,
The length of EG can be determined as follows if EF = 24:
First, we calculate the length of FG using the Pythagorean theorem:
=> FG² = EF² - EG²
=> 10² = 24² - EG²
=> EG² = 24² - 10²
=> EG² = 536
=> EG = √536 ≈ 23.14
Consequently, EG 23.14 when FG = 10 and GH = 7 if E is the right angle apex of a right triangle EFG and EF = 24.

For a sample of 20 IQ scores the mean score is 105. 8. The standard deviation, o, is 15. Determine
whether a normal distribution or a t-distribution should be used or whether neither of these can be used
to construct a confidence interval. Assume that IQ scores are normally distributed,
A) Use normal distribution,
B) Cannot use normal distribution or t-distribution,
C) Use the t-distribution
The 95% confidence interval for the population mean IQ score is (99.62, 111.98), therefore option(A) use normal distribution
Since the sample size is greater than 30 (n=20), we can use the normal distribution to construct a confidence interval for the population mean.
We can use the formula:
Confidence Interval = sample mean ± z (standard error)
where z is the critical value from the standard normal distribution corresponding to the desired level of confidence, and the standard error is calculated as:
standard error = o / sqrt(n)
where o is the sample standard deviation and n is the sample size.
Assuming a 95% confidence level, we can find the critical value z from the standard normal distribution table or using a calculator. The critical value for a 95% confidence level is 1.96.
Substituting the values in the formula, we get:
Confidence Interval = 105.8 ± 1.96 × (15 / sqrt(20))
Confidence Interval = 105.8 ± 6.18
Therefore, the 95% confidence interval for the population mean IQ score is (99.62, 111.98).
Therefore, we can use the normal distribution to construct a confidence interval for the population mean IQ score.
Therefore, the correct option is (A) Use normal distribution.

A container in the shape of a triangular prism is used to hold a slice of pizza. The dimensions of the container are shown in the diagram.
Pizza, 10.8 inches, 7.2 inches, 1.5 inches, 9 inches
What is the volume of the container in cubic inches?
For the pizza box shaped in triangular prism, the volume is obtained as 58.32 cubic inches.
What is volume?
Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
The volume of a triangular prism is given by the formula:
V = (1/2) × base × height × length
where the base and height are the dimensions of the triangular base and the length is the height of the prism.
In this case, the base of the prism is a right-angled triangle with base 10.8 inches and height 7.2 inches.
The area of the base can be found as -
Area = (1/2) × base × height
= (1/2) × 10.8 × 7.2
= 38.88 square inches
The length of the prism is given as 9 inches.
Therefore, the volume of the container can be calculated as -
V = (1/2) × base × height × length
= 38.88 × 1.5
= 58.32 cubic inches
Hence, the volume of the container is 58.32 cubic inches.

To calculate a confidence interval for the difference between the proportions of acceptable DVDs produced by two different fabricating machines, we need to ensure that the following conditions are met:
Random: The sample of DVDs from each machine should be selected randomly, without any bias. This is important to ensure that the sample is representative of the population of all DVDs produced by each machine.
The sample size should be no more than 10% of the population of DVDs produced by each machine. This is important to ensure that the sampling distribution of the sample proportions is approximately normal.
Large counts: The number of acceptable and unacceptable DVDs in each sample should be large enough to satisfy the normal approximation to the sampling distribution of the sample proportions.
Therefore, the correct answer is (e) Random: met, 10%: met, Large Counts: met. All conditions for calculating a confidence interval for the difference between the proportions of acceptable DVDs produced by two different fabricating machines are met in this scenario.

Answer:
See attached image
Step-by-step explanation:
This is how I did it
I made point A as (0,0)
Point B is 12 units right and 4 units up from A. So B is(12,4)
Point C is 8 units right and 8 units down from A so it is at (8, -8)
When dilated by 1/4 with point A as center of dilation, B coordinates are reduced by 1/4 so the image B' coordinates are (12/4, 4/4) = (3,1)
C coordinates are reduced by 1/4 so C' coordinates of image are (8/4, -8/4) = (2, -2)
The A' coordinates are unchanged at A'(0,0)
So the image is A'B'C' as shown in the blue triangle
I do not know what that other triangle is for, it plays no role in the dilation
I also realize you may have been given some other strategy for solving but this is the way I did it

Points P,Q,S appear in that order on a line. The ratio PQ:QR is 3:4. The ratio QR:RS is 2:5. The length PQ is 6 in. Find the length PS
Based on according to the ratio given for PQ:QR, The length of side PS on the line is 34 inches.
What is an equation?We can use the ratios given to find the lengths of the other segments and then add them up to get the length of PS.
Let x be the length of QR. Then, according to the ratio given for PQ:QR, we have:
PQ:QR = 3:4
6:x = 3:4
Multiplying both sides by 4x, we get:
24 = 3x
x = 8
So, QR is 8 inches long. Now, using the ratio given for QR:RS, we have:
QR:RS = 2:5
8:y = 2:5
Multiplying both sides by 5y, we get:
40 = 2y
y = 20
So, RS is 20 inches long. Finally, we can add up the lengths of PQ, QR, and RS to get the length of PS:
PS = PQ + QR + RS
PS = 6 + 8 + 20
PS = 34
Therefore, the length of PS is 34 inches.

• À. True
• B. False
Finding a line segment parallel to another segment and passing through a given point is true.
What is line segment?A line segment is a finite portion of a line that is bounded by two distinct points.
According to question:The statement is asking whether the following method is true or false for finding a line segment parallel to another segment and passing through a given point:
Take a piece of paper.Fold the paper so that the fold line goes through the given point.Place the original segment on the paper so that one end of the segment is on one side of the fold and the other end is on the other side of the fold.Trace the segment onto the paper on both sides of the fold.Remove the original segment and connect the two traced segments with a straight line.This method is called the "fold-and-copy" method, and it is a valid way to construct a segment parallel to another segment and passing through a given point. The reason this works is because when the paper is folded along the given point, the fold line is perpendicular to the original segment. When the segment is copied onto the paper on both sides of the fold, the resulting segments are also perpendicular to the fold line. Since two lines that are both perpendicular to the same line are parallel, the resulting segment is parallel to the original segment. The resulting segment also passes through the given point, since it was copied from the original segment which passes through the given point. Therefore, the statement is true.

In a fraction the numerator is 1 less than the denominator if 1 is added to the numerator and 5 to denominator the fraction becomes 1 / 2 find the original fraction
If in a fraction the numerator is 1 less than the denominator if 1 is added to the numerator and 5 to denominator the fraction becomes 1 / 2 . The the original fraction is4/5.
What is the original fraction?Let's assume that the denominator of the original fraction is x. Then, according to the problem, the numerator is x - 1.
If 1 is added to the numerator and 5 is added to the denominator, we get:
(x - 1 + 1) / (x + 5) = 1/2
Simplifying the left side of the equation, we get:
x / (x + 5) = 1/2
Multiplying both sides by 2(x + 5), we get:
2x = x + 5
Subtracting x from both sides, we get:
x = 5
So, the denominator of the original fraction is 5, and the numerator is 5 - 1 = 4.

x = 2 and y = 0
Step-by-step explanation:
Let's solve your system by elimination.
2x−3y=4;4x+3y=8
2x−3y=4
4x+3y=8
Add these equations to eliminate y:
6x=12
Then solve 6x=12 for x:
6x=12
x = 2
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
2x−3y=4
Substitute 2 for x in 2x−3y=4:
(2)(2)−3y=4
−3y+4=4 (Simplify both sides of the equation)
−3y+4+−4=4+−4 (Add -4 to both sides)
−3y=0

The plan for a new football stadium calls for the stands to be in a region defined by two concentric ellipses. The outer ellipse is to be 240 yd long and 200 yd wide. The inner ellipse is to be 200 yd long and 100 yd wide. A football field of standard dimensions, 120 yd by 160 ft, will be laid out in the center of the inner ellipse.
To find the particular equations of the two ellipses, we can make use of the following: standard form of equation of an ellipse:x2/a2 + y2/b2 = 1 The outer ellipse: Major axis = 240 yd = 480 yd/2a = 480/2 = 240 yd Minor axis = 200 yd/2b = 100 yd Now, substituting the values in the standard equation of an ellipse, we have:x2/2402 + y2/1002 = 1Multiplying both sides by 2402 * 1002, we have: 1002x2 + 2402y2 = 2402 * 1002
The particular equation of the outer ellipse is therefore: 1002x2 + 2402y2 - 2402 * 1002 = 0 The inner ellipse: Major axis = 200 yd = 400 yd/2a = 400/2 = 200 yd Minor axis = 100 yd/2b = 50 yd Now, substituting the values in the standard equation of an ellipse, we have: x2/2002 + y2/502 = 1 Multiplying both sides by 2002 * 502, we have:502x2 + 2002y2 = 2002 * 502The particular equation of the inner ellipse is therefore:502x2 + 2002y2 - 2002 * 502 = 0
The eccentricity of an ellipse is given by the formula: e = √(1 - b2/a2)For the outer ellipse: a = 240, b = 100∴ e = √(1 - 1002/2402) = √0.694 = 0.833 For the inner ellipse: a = 200, b = 50∴ e = √(1 - 502/2002) = √0.9375 = 0.968
To find the clearance between the corner of the field and the inner ellipse in the direction of the end line, we need to find the distance between the foci of the inner ellipse, which is given by: d = 2 * √(a2 - b2)where a = 200 yd and b = 50 yd. Substituting the values, we have: d = 2 * √(2002 - 502)≈ 387.29 yd The clearance between the corner of the field and the inner ellipse in the direction of the end line is approximately 387.29 - 120/2 = 343.29 yd.
The area of the stands is the area between the two ellipses. Using the formula given in the question, A = πab, where a = 240 yd/2 and b = 200 yd/2, the area is: A = π * 120 * 100 = 37,699.1 sq yd Approximate seating capacity of the stadium will be number of seats = 37,699.1 / 0.8 = 47123.88 ≈ 47124 seats.
A circle is a special case of an ellipse, where both radii are equal. In the case of a circle with radius r, the formula for the area of an ellipse is reduced to the formula for the area of a circle: A = πab = πr2 = area of a circle

Answer:
[tex]x=\frac{7}{30}[/tex]
Step-by-step explanation:
Solve for x:
[tex]x+\frac{2}{3}=\frac{9}{10}[/tex]
Subtract [tex]\frac{2}{3}[/tex] on both sides
[tex]x=\frac{7}{30}[/tex]
Answer:
X= 7/30
Step-by-step explanation:
subtract 2/3 from both sides.
X+ 2/3 = 9/10
X +2/3 -2/3 =9/10 -2/3
simplify the expression
X + 2/3 -2/3 =9/10 -2/3
X=7/30
