Data from the past three months at Gizzard Wizard (GW) shows the following: Month Prod. Volume DM DL MOH May 1000 $400.00 $600.00 $1200.00 June 400 160.00 240.00 480.00 July 1600 640.00 960.00 1920.00 If GW uses DM$ to apply overhead, what is the application rate?
The application rate is 3 (per DM$).
The given below table shows the monthly production volume, direct materials, direct labor, and manufacturing overheads for the past three months at Gizzard Wizard (GW):
Month Prod. Volume DM ($)DL ($)MOH ($)May 1000$400.00$600.00$1200.00
June 400160.00240.00480.00
July 1600640.00960.001920.00
By using DM$ to apply overhead, we have to find the application rate. We know that the total amount of manufacturing overheads is calculated by adding the cost of indirect materials, indirect labor, and other manufacturing costs to the direct costs. The formula for calculating the application rate is as follows:
Application rate (per DM$) = Total MOH cost / Total DM$ cost
Let's calculate the total cost of DM$ and MOH:$ Total DM$ cost = $400.00 + $160.00 + $640.00 = $1200.00$
Total MOH cost = $1200.00 + $480.00 + $1920.00 = $3600.00
Now, let's calculate the application rate:Application rate (per DM$) = Total MOH cost / Total DM$ cost= $3600.00 / $1200.00= 3
Therefore, the application rate is 3 (per DM$).
Hence, the required answer is "The application rate for GW is 3 (per DM$)."

Consider the function f(x)= x^2-4x^2
a. Find the domain of the function.
b. Find all x- and y-intercepts.
c. Is this function even or odd or neither?
d. Find H.A. and V.A.
e. Find the critical points, the intervals on which f is increasing or decreasing, and all extrem values of f.
f. Find the intervals where f is concave up or concave down and all inflection points.
g. Use the information above to sketch the graph.
So, the function has an extremum value of -4 at x = 2, a. The domain of a function is the set of all possible input values for which the function is defined.
In this case, the function is a polynomial, so it is defined for all real numbers. Therefore, the domain of the function f(x) = x^2 - 4x is the set of all real numbers, (-∞, ∞).
b. To find the x-intercepts of a function, we set the function equal to zero and solve for x. In this case, we have:
x^2 - 4x = 0
x(x - 4) = 0
x = 0 or x = 4
So, the x-intercepts of the function are x = 0 and x = 4.
To find the y-intercept, we evaluate the function at x = 0:
f(0) = 0^2 - 4(0) = 0
So, the y-intercept of the function is y = 0.
c. To determine whether a function is even or odd, we check whether the function satisfies the properties of even or odd functions. In this case, the function f(x) = x^2 - 4x is neither even nor odd, because it does not satisfy the symmetry conditions for even or odd functions.
d. The function f(x) = x^2 - 4x is a quadratic function, and as x approaches positive or negative infinity, the function also approaches positive infinity. Therefore, there is no horizontal asymptote (H.A.).
To find the vertical asymptote (V.A.), we need to determine if there are any values of x for which the function approaches infinity or negative infinity. However, in the case of the given function, there are no vertical asymptotes because the function is defined for all real numbers
parts e, f, and g:
To find the critical points, we find the values of x where the derivative of the function is zero or undefined. In this case, the derivative of f(x) = x^2 - 4x is f'(x) = 2x - 4. Setting f'(x) equal to zero, we get:
2x - 4 = 0
2x = 4
x = 2
So, the critical point is x = 2.
To determine the intervals of increasing and decreasing, we check the sign of the derivative on either side of the critical point. For x < 2, f'(x) is negative, indicating a decreasing interval. For x > 2, f'(x) is positive, indicating an increasing interval.
To find the extremum values, we substitute the critical point x = 2 into the original function:
f(2) = 2^2 - 4(2) = -4
So, the function has an extremum value of -4 at x = 2.
To find the intervals of concavity and the inflection points, we take the second derivative of the function.
The second derivative of f(x) = x^2 - 4x is f''(x) = 2. Since the second derivative is constant and positive, the function is concave up for all values of x and there are no inflection points.

If the population standard deviation of a sample increases without other changes, what is most likely to happen to the confidence interval?
If the population standard deviation of a sample increases without other changes, the confidence interval is most likely to widen.
This is because the standard deviation is a measure of the spread of the data, so if it increases, the data points are more spread out from the mean. As a result, the range of values that could reasonably contain the true population parameter (i.e., the confidence interval) needs to be wider to account for the increased variability in the sample.
If the population standard deviation of a sample increases without other changes, the confidence interval is most likely to become wider.
When standard deviation increases, it indicates more variability in the data. As a result, the confidence interval, which is a range of values that estimates the true population parameter with a certain level of confidence, needs to be wider to account for the increased variability. This ensures that the true population parameter is still captured within the interval with the same level of confidence.

It took Franny 5 minutes to walk each lap. The correct option is B.
Franny spent a total of 35 minutes walking around the track and made 7 laps around the track, so the total time for all 7 laps is 35 minutes. Let's assume it took Franny t minutes to walk each lap. Then, we can set up the following equation:
7t = 35
We can solve for t by dividing both sides of the equation by 7:
t = 35/7 = 5
Therefore, the correct option is B.

If the graph of y = |x| is translated so that the point (1, 1) is moved to (4, 1), what is the equation of the new graph?
Answer:
y = |x - 4|
Step-by-step explanation:
Because the x value is the only variable that changed, it means the graph has moved only horizontally. The only value you are adding to will be inside the absolute value, not outside (as that is vertical transformation)
If that is the case, the graph has only moved right from (1, 1) to (4, 1), and thus from the parent graph y = |x| you would derive y = |x - 4|.

(a) [infinity]∑n=116n∑n=1[infinity]16n
(b) [infinity]∑n=1n+4n2+8n+4
The series diverges with an integral of 1/ln(16) and the series converges with an integral of 1/4 and a sum of 1/2.
We can use the integral test to determine the convergence of the series ∑n=1∞ 1/6n. The integral of the function f(x) = 1/6x is:
\(∫f(x) dx = (1/6) ln(x) + C\)
Using the limits of integration from 1 to ∞, we get:
∫1∞ f(x) dx = (1/6) ln(∞) - (1/6) ln(1) = ∞
Since the integral diverges, the series also diverges.
We can use the integral test to determine the convergence of the series ∑n=1∞ \((n+4)/(n^2+8n+4\)). The integral of the function f(x) = \((x+4)/(x^2+8x+4)\) is:
∫f(x) dx = (1/2) ln(x^2 + 8x + 4) + 3 ln|x + 4| + C
Using the limits of integration from 1 to ∞, we get:
∫1∞ f(x) dx = (1/2) ln(∞) + 3 ln(∞ + 4) - (1/2) ln(13) - 3 ln(5) = ∞

Set (X, Y) Unif([0, 1] x [-1,0]). This means that (X, Y) is a uniform random point on the rectangular [0, 1] x [-1,0] then X and Y are independent.
How to explain the informationSince the area of this region is 1, we have:
f(X,Y) = 1
Now we need to find the marginal PDFs of X and Y. In order to find fX(X), we integrate f(X,Y) over all possible values of Y:
fX(X) = ∫ f(X,Y) dy
= ∫ 1 dy (since f(X,Y) = 1)

Similarly, to find f_Y(Y), we integrate f(X,Y) over all possible values of X:
f_Y(Y) = ∫ f(X,Y) dx

hat formula is used to gain information about an individual data value when the variable is normally distributed?
The formula used to gain information about an individual data value when the variable is normally distributes is, Z = (X - μ)/σ.
What is standard normal distribution?
The standard normal distribution, also known as the z-distribution, is a unique type of normal distribution in which the mean and standard deviation are both equal to 1.
Any normal distribution's values can be transformed into z scores to standardize it.
Z scores indicate the number of standard deviations away from the mean that each value represents.
The Z score is determined by the number of standard deviations above or below the mean for the standard normal distribution.
When a variable (let's say X) is normally distributed, then to get insights from its distribution, we transform it (i.e. X) into standardized variable (which constitutes "Standard" Normal Distribution).
Standardized variable, Z, is given by (X - μ)/σ
Hence, option B is correct answer. Z = (X - μ)/σ.
