In order to verify the accuracy of their financial accounts, companies use auditors on a regular basis to verify accounting entries. The company’s employees make erroneous entries 5% of the time. Suppose that an auditor randomly checks three entries.
a. Find the probability distribution for Y , the number of errors detected by the auditor.
b. Construct a probability histogram for p(y).
c. Find the probability that the auditor will detect more than one error.
To find the probability distribution for Y, the number of errors detected by the auditor, we can use the binomial distribution formula. The binomial distribution is used when there are only two possible outcomes, success or failure, and each trial is independent.
In this case, the probability of success (detecting an error) is 5% or 0.05, and the probability of failure (not detecting an error) is 1 - 0.05 = 0.95.
a. To find the probability distribution for Y, we can use the formula for the binomial distribution:
P(Y = y) = (nCk) * p^k * (1-p)^(n-k)
where n is the number of trials (3 in this case), k is the number of successes (errors detected), p is the probability of success (0.05), and (nCk) is the combination formula.
For y = 0:
P(Y = 0) = (3C0) * (0.05)^0 * (0.95)^(3-0) = (1) * (1) * (0.95)^3 = 0.857375
For y = 1:
P(Y = 1) = (3C1) * (0.05)^1 * (0.95)^(3-1) = (3) * (0.05) * (0.95)^2 = 0.135375
For y = 2:
P(Y = 2) = (3C2) * (0.05)^2 * (0.95)^(3-2) = (3) * (0.05)^2 * (0.95)^1 = 0.007125
For y = 3:
P(Y = 3) = (3C3) * (0.05)^3 * (0.95)^(3-3) = (1) * (0.05)^3 * (0.95)^0 = 0.000125
So the probability distribution for Y is:
Y = 0 with probability 0.857375
Y = 1 with probability 0.135375
Y = 2 with probability 0.007125
Y = 3 with probability 0.000125
b. To construct a probability histogram for p(y), you can create a bar graph where the x-axis represents the number of errors detected (Y) and the y-axis represents the probability (P(Y = y)). Each bar will have a height corresponding to the probability.
c. To find the probability that the auditor will detect more than one error, we need to calculate the sum of the probabilities for Y = 2 and Y = 3:
P(Y > 1) = P(Y = 2) + P(Y = 3) = 0.007125 + 0.000125 = 0.00725
Therefore, the probability that the auditor will detect more than one error is 0.00725.

Given a cone with height 10 feet and diameter of 22 feet, determine the radius of the smaller cone created when a horizontal plane passes through the cone at exactly 4 feet from the base
The radius of the smaller cone created when a horizontal plane passes through the cone at exactly 4 feet from the base is 6.6 feet.
To determine the radius of the smaller cone created when a horizontal plane passes through the cone at exactly 4 feet from the base, we can use similar triangles.
The given cone has a height of 10 feet and a diameter of 22 feet. The radius of the given cone is half of the diameter, so it is 22/2 = 11 feet.
When a horizontal plane passes through the cone at exactly 4 feet from the base, it divides the cone into two parts: the smaller cone and the frustum (the remaining part of the cone).
The height of the smaller cone is the distance from the 4-feet mark to the top of the cone, which is 10 - 4 = 6 feet.
Since the two cones are similar, their corresponding dimensions are proportional. The ratio of the corresponding heights is the same as the ratio of the corresponding radii.
So, we can set up the following proportion:
(r_small / r_given) = (h_small / h_given)
Substituting the values we have:
(r_small / 11) = (6 / 10)
Cross-multiplying:
10 * r_small = 11 * 6
r_small = (11 * 6) / 10
r_small = 66 / 10
r_small = 6.6 feet
Therefore, the radius of the smaller cone created when a horizontal plane passes through the cone at exactly 4 feet from the base is 6.6 feet.

does it make sense that the number of cats falling from the 5th floor would be greater than those of the 4th? why or why not?
No, it does not make sense that the probability of cats falling from the 5th floor would be greater than those of the 4th. The force of gravity is the same regardless of the floor, so the number of cats falling should be the same no matter what floor they start from.
The force of gravity is a constant force that is the same on all floors. This means that the same amount of force is acting on the cats, no matter which floor they start from. Therefore, the number of cats falling from the 5th floor should be the same as the number falling from the 4th floor. The number of cats falling from a higher floor may be greater if there are extra factors, such as wind, that could affect their fall, but the force of gravity does not change with the floor. Therefore, it does not make sense for the number of cats falling from the 5th floor to be greater than those of the 4th

What is set?
The mathematical logic subfield of set theory investigates sets, which can be loosely defined as collections of objects. Although any object can be combined into a set, set theory, as a mathematical discipline, focuses primarily on those that are relevant to mathematics as a whole.
Given union of set
(A ∪ B),
The set of all objects that are members of either A or B, or both, is the union of the sets A ∪ B.
let us take example,
A = { 1, 2, 3, 4}
B = {3, 4, 5, 6, 7}
(A ∪ B) = { 1, 2, 3, 4} ∪ {3, 4, 5, 6, 7}
we can simply write all of A and B's elements in a single set to avoid duplicates to find A U B.

330 grams decays by 25.5% per minute. how much of the element is remaining after 5 minutes
The remaining amount of the element after 5 minutes after exponential decay is approximately 114.26 grams.
To find out how much of the element is remaining after 5 minutes, we can use the formula for exponential decay.
First, we need to calculate the decay factor. The decay factor is equal to 1 minus the percentage decay rate, which is 25.5%, converted to decimal form (0.255). So, the decay factor is 1 - 0.255 = 0.745.
Next, we can calculate the remaining amount of the element by multiplying the initial amount (330 grams) by the decay factor raised to the power of the number of minutes (5 minutes).
Remaining amount = 330 grams * (decay factor)^(number of minutes)
Remaining amount = 330 grams * 0.745^5
Calculating this expression, we find that the remaining amount of the element after 5 minutes is approximately 114.26 grams.

What is eigenvalue?
In linear algebra, an eigenvector or characteristic vector of a linear transformation is a nonzero vector that, when the linear transformation is applied to it, changes at most by a scalar factor. The factor by which the eigenvector is scaled is known as the associated eigenvalue, frequently denoted by lambda.
a) -4
b) 1

a) The matrix A is given by:
\(A=\left[\begin{array}{ccc}-3 & 0 & 1 \\2 & -4 & 2 \\-3 & -2 & 1\end{array}\right]\\\)
where lambda are the eigenvalues and I is the identity matrix. By replacing you obtain:
\(A-\lambda I=\left[\begin{array}{ccc}-3-\lambda & 0 & 1 \\2 & -4-\lambda & 2 \\-3 & -2 & 1-\lambda\end{array}\right]\)
and by taking the determinant:\(\begin{aligned}& {[(-3-\lambda)(-4-\lambda)(1-\lambda)+(0)(2)(-3)+(2)(-2)(1)]-[(1)(-4-\lambda)(-3)+(0)(2)(1-} \\& \lambda)+(2)(-2)(-3-\lambda)]=0 \\& -\lambda^3-6 \lambda^2-12 \lambda-16=0\end{aligned}\)
and the roots of this polynomial is:
\(\begin{aligned}& \lambda_1=-4 \\& \lambda_2=-1+i \sqrt{3} \\& \lambda_3=-1-i \sqrt{3}\end{aligned}\)

A student decided to research primate psychology for their science project. They measured how long it took gorillas to adapt to their new habitat when moved from one zoo to another. They measured how long it took the new gorilla to interact regularly (more than 3 times per day) with the gorillas that already live there. Seven different cases were examined and the data collected. What can be said about the data?
The question is not complete, so i have attached it.
Answer:
Option A - The data may not be reliable because there is an outlier.
Step-by-step explanation:
Looking at the question attached and the number of the gorrila vis - a - vis the time to interact, we can see that majority of the time to interact falls between 2.5 and 3.4.
However, we have a time of 8.3 days which is for gorrila 3.
This 8.3 is far higher than the range of the other values. Thus, we have an outlier because an outlier is a value is much more smaller or larger than most of the other values in a set of given data.
Thus, the data may not be reliable because there is an outlier.
What is the loan factor is Magada decides to pay her monthly repayments over a 25 year period with an interest of 10. 75%
Magada's loan factor is approximately 0.006367. This means that for every $1 borrowed, Magada will have to pay approximately $0.006367 per month for the next 25 years to repay the loan with an interest rate of 10.75%.
To calculate the loan factor, we first need to calculate the monthly interest rate and the total number of monthly payments.
Monthly interest rate = Annual interest rate / 12
= 10.75% / 12
= 0.8958%
Monthly payments = Number of years * 12
= 25 * 12
= 300
Now, we can use loan factor formula, which is:
Loan factor = [monthly interest rate * (1 + monthly interest rate)^n] / [(1 + monthly interest rate)^n - 1]
Substituting the values, we get:
Loan factor = [0.008958 * (1 + 0.008958)^300] / [(1 + 0.008958)^300 - 1]

m=y₂-y₁/x₂-x₁
Let us write the given equation y=-1/4x-1
If we compare the given equation with slope intercept form
We get to know slope of line m is -1/4.
It two lines are perpendicular then the product of their slopes will be -1
-1/4×m=-1
m=4
Hence slope of line perpendicular to the line y=-1/4x-1 is 4.
