And you would only fill in half a circle after that
Hope this helps
Answer: Choice H (upper right corner)
====================================================
Explanation:
Refer to the diagram below.
I started with the set of five circles you were given. Then I cut each of them in half. This results in 2*5 = 10 sections (each section is numbered in blue). If you shade 9 of those 10 sections, then you'll represent the fraction 9/10. This is what choice H represents, so that's why it's the answer
9/10 = 0.90 in decimal form
0.90 = 90% in percent form

Life in the neighborhood depicted in the film "Los Olvidados" is characterized by challenging economic and social conditions.
How do the economic and social conditions shape life in the neighborhood?The neighborhood in "Los Olvidados" is portrayed as a poverty-stricken area where the residents struggle to make ends meet. The film explores the lives of marginalized individuals most particularly young boys, who are caught in a cycle of poverty, violence, and neglect.
The economic conditions in the neighborhood are harsh, with limited opportunities for employment and a lack of access to basic necessities. As a result, the residents are often forced into criminal activities to survive leading to a high level of violence and crime within the community.
Moreover, the social conditions exacerbate the challenges faced by the neighborhood. There is a sense of abandonment and neglect from the government and wider society with little support or resources available to address the issues faced by the residents.

The way the federal tax affects a gross biweekly pay of $740 for a single person claiming 1 exemption is D. It decreases net pay by $65.
How does the federal tax affect the pay ?Looking at the table, for someone earning at least $740 but less than $760, and claiming 1 withholding allowance, the amount of income tax withheld is $65. This means that $65 will be subtracted from their gross pay.
Therefore, the answer is it t decreases net pay by $65.
This is because the gross pay is the amount before any deductions, and the net pay is the amount after deductions (like income tax). So, the federal tax decreases the net pay by $65.

Find the eigenvalues λn and eigenfunctions yn(x) for the given boundary-value problem. (Give your answers in terms of n, making sure that each value of n corresponds to a unique eigenvalue.)
y'' + λy = 0, y(0) = 0, y(π/4) = 0
Answers
the eigenvalues λn are given by \(\lambda n = n^2 = (4k)^2 = 16k^2\), and the corresponding eigenfunctions yn(x) are given by yn(x) = A sin(4kx), where k is an integer.
What is eigenvalues?
Eigenvalues are essential in linear algebra and are closely related to square matrices. An eigenvalue is a scalar value that describes how a matrix affects a vector along a particular direction.
The given boundary-value problem is y'' + λy = 0, with the boundary conditions y(0) = 0 and y(π/4) = 0. To find the eigenvalues and eigenfunctions, we can assume a solution of the form y(x) = A sin(nx), where A is a constant and n is a positive integer representing the eigenvalue.
Substituting this solution into the differential equation, we have:
y'' + λy = -A \(n^2\) sin(nx) + λA sin(nx) = 0
This equation holds for all x if and only if the coefficient of sin(nx) is zero. Thus, we obtain:
A \(n^2\) + λA = 0
Simplifying this equation, we have:
λ = \(n^2\)
So, the eigenvalues λn are given by λn = \(n^2\), where n is a positive integer.
To find the corresponding eigenfunctions yn(x), we substitute the eigenvalues back into the assumed solution:
yn(x) = A sin(nx)
Now, applying the boundary conditions, we have:
y(0) = A sin(0) = 0, which implies A = 0 (since sin(0) = 0)
y(π/4) = A sin(nπ/4) = 0
For the second boundary condition to be satisfied, we need sin(nπ/4) = 0, which occurs when nπ/4 is an integer multiple of π (i.e., nπ/4 = kπ, where k is an integer). This gives us:
n = 4k, where k is an integer
Therefore, the eigenvalues λn are given by \(\lambda n = n^2 = (4k)^2 = 16k^2\), and the corresponding eigenfunctions yn(x) are given by yn(x) = A sin(4kx), where k is an integer.

Answers
Having a small sample size compared to a large one may result in biased results due to sampling error.
Sampling is a crucial aspect of research because it allows researchers to generalize their findings to a larger population. In the case of the coal mine study, having a small sample size compared to a large one may result in what is known as a sampling error.
Sampling error is the difference between the sample's statistics and the true population's parameters. It occurs when the sample is not representative of the entire population, leading to biased results. In other words, the smaller the sample size, the greater the chance of sampling error occurring.
To understand this concept better, consider an example. Suppose we are trying to determine the average height of high school students in a particular city.
We randomly select ten students from one school and another ten from a different school, giving us a total of twenty students. If the average height of these students is 5'6", this may not be representative of the entire high school student population in the city. However, if we increase the sample size to 1000 students, the average height would likely be more accurate.

an unfair coin has probability 0.4 of landing heads. the coin is tossed three times. what is the probability that it lands heads at least once? round the answer to four decimal places.
Answers
The probability that it lands heads at least once is 1.0720.
Probability is the measure of the likelihood of an event occurring. In this case, we are looking at the probability of a coin landing heads at least once after three tosses.
Let's denote the event of the coin landing heads on the first toss as event A, the event of the coin landing heads on the second toss as event B, and the event of the coin landing heads on the third toss as event C.
The probability of landing heads at least once is equal to the sum of the probabilities of each individual event occurring (A, B, or C) minus the probability of all three events occurring (A and B and C).
P(A or B or C) = P(A) + P(B) + P(C) - P(A and B and C)
Since the coin is unfair and has a probability of 0.4 of landing heads, P(A) = P(B) = P(C) = 0.4.
Using the formula for the probability of multiple events happening simultaneously, we find that P(A and B and C) = P(A) * P(B) * P(C) = 0.4 * 0.4 * 0.4 = 0.064.
Plugging in all the values, we get:
P(A or B or C) = 0.4 + 0.4 + 0.4 - 0.064 = 1.136 - 0.064 = 1.072
Rounding to four decimal places, the answer is 1.0720, which means that the probability of the coin landing heads at least once after three tosses is 1.0720.

Zaid picked 6 and 1-eighth kilograms of peaches. He picked 3-eighths kilogram more peaches than his sister. How many kilograms of peaches did his sister pick?
Answers
Zaid picked 6 and 1-eighth kilograms of peaches, which is equivalent to 49/8 kilograms.
Let's call the amount of peaches Zaid's sister picked "x" kilograms. We know that Zaid picked 3-eighths kilogram more than his sister, which can be written as: 49/8 = x + 3/8
To solve for "x," we can subtract 3/8 from both sides: 49/8 - 3/8 = x
Simplifying the left side: 46/8 = x
Reducing the fraction: 23/4 = x

Zaid's sister picked 5 and 3-quarters kilograms of peaches.
Explanation:The question involves a scenario where Zaid has picked 6 and 1-eighth kilograms of peaches, which is 3-eighths of a kilogram more than the weight of the peaches his sister picked.
To find out how many kilograms Zaid’s sister picked, we subtract 3-eighths of a kilogram from Zaid's total weight of peaches, because that is the extra amount Zaid picked compared to his sister.
Therefore, Zaid's sister picked 6 and 1-eighth kilograms minus 3-eighths kilogram. When you take away 3-eighths from 1-eighth, the result is minus 2-eighths, which is the same as minus 1-quarter.So, Zaid's sister picked 6 kilograms minus 1-quarter kilogram, which is 5 and 3-quarters kilograms of peaches.
