The probability distribution function of Y = |X| is given by:
P(Y ≤ y) = P(|X| ≤ y) = P(-y ≤ X ≤ y)
Since X ~ N(0, 2), we can use the standard normal distribution to find the probability;
P(Y ≤ y) = P(Z ≤ y/√2) - P(Z ≤ -y/√2)
where Z is a standard normal random variable.
To find E(|X|), we can use the formula:
E(|X|) = √(2/π) * σ
where σ is the standard deviation of X. Since X ~ N(0, 2), σ = √2, so:
E(|X|) = √(2/π) * √2 = √(4/π)
To find Var(|X|), we can use the formula:
Var(|X|) = E(X^2) - E(|X|)^2
Since X ~ N(0, 2), E(X^2) = σ^2 = 2. And we already found E(|X|) = √(4/π), so:
Var(|X|) = 2 - (4/π) = (2π - 4)/π
Therefore, the probability distribution function of Y = |X| is P(Y ≤ y) = P(Z ≤ y/√2) - P(Z ≤ -y/√2), the expected value of |X| is E(|X|) = √(4/π), and the variance of |X| is Var(|X|) = (2π - 4)/π.

Circle B is a dilation of circle A. How does the ratio of arc length compare to the scale factor?
We can conclude that the Ratio of arc = scale factor of dilation.
What is an Arc of a circle?An arc in mathematics is a section of a circle's or curve's perimeter. An open curve is another name for it.
The circumference of a circle, sometimes referred to as its perimeter, serves as its boundary. The distance between any two locations traced along the circle of an arc is hence its length.
Given : Radius of original circle A = 3
Radius of Dilation circle B = 9
We know that, Scale factor of dilation =
Dimension of Dilation shape / Dimension of original shape
So, Scale factor of given dilation = Radius of Circle B / Radius of Circle A
= 9/3
= 3.
Now, we know that arc of a circle can be found by using formula:
= Ф × π/180° × r
Arc of Circle A= 90 × π/180 × 3
= 3π/2
Arc of Circle B = 90 × π/180 × 9
= 9π/2
So, Ratio of arc = Arc of Circle B/Arc of Circle A
= 9π/2 ÷ 3π/2 = 3.
Hence, we can see that Ratio of arc = scale factor of dilation.

Find and simplify f (-x) and use it to determine itf is even, odd, or neither. Use * to enter exponents, as in - 3x^5+4x^2 means --3x3 + 4x?. Do not enter any spaces in the answear f(x) = x^4 - 6x + 2 f(-x)+_______
The answer is f(-x) = x^4 + 6x + 2 and the function is neither even nor odd.
To find f(-x), we simply substitute -x for x in the original function:
f(-x) = (-x)^4 - 6(-x) + 2 = x^4 + 6x + 2
Now, to determine if f is even, odd, or neither, we compare f(x) and f(-x). If f(x) = f(-x), then the function is even. If f(x) = -f(-x), then the function is odd. If neither of these conditions are met, then the function is neither even nor odd.
In this case, f(x) = x^4 - 6x + 2 and f(-x) = x^4 + 6x + 2. These are not equal, so the function is not even. However, if we multiply f(-x) by -1, we get:
-f(-x) = -x^4 - 6x - 2
This is also not equal to f(x), so the function is not odd either. Therefore, the function is neither even nor odd.

In another word, calculate the overall chances (expected values) of winning the games before/ and after you played? Note -Before you play, you believe that there is a 1% chance that your probability of winning any given game is 10%. - 2% chance that your winning probability is 20%, and so on.
The overall chances of winning the games before playing were 52%, and after playing and winning once but losing twice, the overall chances of winning are 17.33%. This shows that the new information has changed your belief about the probability of winning, and you now suspect that your chances of winning are lower than before.
Before playing the games, the expected value of winning is calculated by multiplying the probability of winning with the corresponding probabilities and adding them together. This is shown below:
E(win) = (0)(0) + (0.1)(0.01) + (0.2)(0.02) + (0.3)(0.04) + (0.4)(0.1) + (0.5)(0.15) + (0.6)(0.2) + (0.7)(0.25) + (0.8)(0.16) + (0.9)(0.04) + (1)(0) = 0.52
After playing the games and winning once but losing twice, the expected value of winning is calculated by multiplying the probability of winning with the corresponding probabilities, and adding them together. However, the probabilities are adjusted based on the new information. The new probabilities are shown below:
P(win) = (0)(0) + (0.1)(0.01)(1/3) + (0.2)(0.02)(1/3) + (0.3)(0.04)(1/3) + (0.4)(0.1)(1/3) + (0.5)(0.15)(1/3) + (0.6)(0.2)(1/3) + (0.7)(0.25)(1/3) + (0.8)(0.16)(1/3) + (0.9)(0.04)(1/3) + (1)(0)(1/3) = 0.17333

The Pythagorean Theorem is proven.
The reason that we can make the statement BC/AC = CD/AC is because corresponding sides of similar triangles are proportional. This is represented by option D. Corresponding sides of similar triangles are proportional.
To complete the proof of the Pythagorean Theorem, a² + b² = c², we can use the following steps:
As similar triangles have proportional sides, we can write the proportions AB/AC = AC/BC and AB/BC = BC/AC.
By the cross-product property, AB * BC = AC * AC and AB * AC = BC * BC.
By the addition property of equality, AB² + BC² = AC² + BC².
By the segment addition postulate, AC + BC = c.
By factoring, (AC + BC)² = c².
By the distributive property, AC² + 2*AC*BC + BC² = c².
By rearranging the terms, AC² + BC² = c² - 2*AC*BC.
By substituting the values of AC and BC from the proportions in step 1, we get a² + b² = c² - 2*a*b.
By simplifying, we get a² + b² = c².

At a Bloomburg City Council meeting, a plan to fund more swim safety programs was presented. The reasoning behind the request was that less than 40% of children under the age of 5 could pass a swim test. If this is true, the council will agree to fund more programs for these kids. The council decides to take a 200-person volunteer sample of children under 5 years in Bloomburg City and conduct a significance test for H0: p = 0. 40 and Ha: p < 0. 40, where p is the proportion of these children that can pass a swim test. They will perform a significance test at a significance level of α = 0. 05 for the hypotheses.
Part A: Describe a Type II error that could occur. What impact could this error have on the situation? (3 points)
Part B: Out of the 200 children under 5 that volunteered to take a swimming test, 87 passed, resulting in a p-value of 0. 8438. What can you conclude from this p-value given the data of the 200 children is sufficient to perform a significance test for the hypotheses? (4 points)
Part C: What possible defect in the study can you find in Part B? Explain. (3 points)
Part A: In this situation, a Type II error would take place if the council failed to reject the null hypothesis even if it was untrue (i.e., less than 40% of children under the age of 5 could pass a swim test).
what is a Type II error?If the researcher does not reject a null hypothesis that is actually wrong in the population, this is known as a type II error (false-negative). Notwithstanding the fact that type I and type II mistakes cannot be completely prevented, the researcher can lessen their risk by increasing the sample size.
from the question:
Part A: In this situation, a Type II error would take place if the council failed to reject the null hypothesis even if it was untrue (i.e., less than 40% of children under the age of 5 could pass a swim test). This would result in a lost chance to provide these kids with more swim safety training, perhaps placing them in danger of drowning or other swimming-related mishaps.
Part B: We are unable to reject the null hypothesis since the p-value (0.8438) exceeds the significance level (0.05). This indicates that there is insufficient information to draw the conclusion that less than 40% of children under the age of five can pass a swim test. But, since the test only looked at the alternative hypothesis that the fraction is less than 40%, we cannot draw the conclusion that it is exactly 40%.
Part C: One possible defect in the study is the use of a volunteer sample. The children who volunteered to take the swimming test may not be representative of the entire population of children under 5 in Bloomburg City. For example, parents who are more concerned about their children's swimming abilities may be more likely to volunteer their children for the test, leading to a biased sample. To obtain a more representative sample, a random sample of children under 5 could be selected from the population and asked to take the swimming test.

Which graph represents the function f(x)=✔️x-2-2
Answer:
The given function is f(x) = √(x-2) - 2.
The graph that represents this function will have the following characteristics:
The domain of the function is x ≥ 2, since the expression inside the square root must be non-negative.
The function approaches the x-axis but never touches it as x approaches positive infinity, since the square root will always be positive.
The function has a vertical asymptote at x = 2, since the expression inside the square root becomes zero at x = 2.
The function has a horizontal asymptote at y = -2, since the square root term dominates the function as x gets large, and the -2 term remains constant.
Based on these characteristics, you can compare the given graphs to see which one matches the given function.

In this case, the ratio between Alice and Brian is 1:4. This means that for every 1 unit of money that Alice receives, Brian receives 4 units of money. Therefore, the total number of parts in this ratio is 1 + 4 = 5.
To divide £400 in the ratio of 1:4, we need to find out how much of the total amount each part represents. To do this, we divide the total amount by the total number of parts:
£400 ÷ 5 = £80
So each part in this ratio represents £80.
Now that we know the value of each part, we can calculate how much Alice and Brian will receive.
Alice's share is one part, which represents £80. Therefore, Alice will receive
1 part x £80 = £80
Brian's share is four parts, which represents 4 x £80 = £320. Therefore, Brian will receive:
4 parts x £80 = £320

About 5,000 more fans attended the third round finals than the third round time trials.
Calculating the number of fans that attended the finals than the trialsFrom the question, we are to find the approximate difference between the attendance of the third round finals and the third round time trials.
From the given data, we have:
Attendance Time Trials Finals
1st round 12,645 17,352
2nd round 16,234 21,896
3rd round 18,817 23,773
Third round finals attendance = 23,773
Third round time trials attendance = 18,817
The difference between these two numbers is:
23,773 - 18,817 = 4,956
Rounding this to the nearest thousand gives:
4,956 ≈ 5,000
Hence, The number of fans that attended the third round finals than the third round time trials is about 5,000

Lesson 11-4 Three-dimensional Geometry Name "CHTC Lock hart 1. Identify each of the following polyhedra. Aloblique square pyramid
ABCD is the square base and A is the apex. As you can see, the apex is not directly above the center of the base, which makes this an oblique square pyramid.
An oblique square pyramid is a type of three-dimensional geometry that has a square base and four triangular faces that meet at a point, called the apex, but the apex is not directly above the center of the base. In other words, the pyramid is "tilted" or "leaning" to one side.
The key difference between an oblique square pyramid and a regular square pyramid is the location of the apex. In a regular square pyramid, the apex is directly above the center of the base, while in an oblique square pyramid, the apex is off-center.
Here is a diagram of an oblique square pyramid:
AIn this diagram, ABCD is the square base and A is the apex. As you can see, the apex is not directly above the center of the base, which makes this an oblique square pyramid.

(a) Factor f(x)=x^(3)-2x^(2)+49x-98 into factors of the form (x-c), given that 2 is a zero x^(3)-2x^(2)+49x-98
The factors of the form (x - c) are (x - 2) and (x² + 49).
To factor the polynomial f(x) = x³ - 2x² + 49x - 98 into factors of the form (x - c), we can use synthetic division with the given zero of 2.
2 | 1 -2 49 -98
| 2 0 98
1 0 49 0
The result of the synthetic division gives us the quotient (x² + 49) and a remainder of 0, confirming that 2 is indeed a zero of the polynomial.
Now we can write the polynomial as the product of (x - 2) and the quotient (x² + 49):
f(x) = (x - 2)(x² + 49)
Since the quadratic factor (x² + 49) cannot be factored further using real numbers, the final factorization of the polynomial is:
f(x) = (x - 2)(x² + 49)
