Labor Variances Ellen Chenoweth, the manager of the city of St. Paul road maintenance shop, uses standards to judge performance, the actual labor rate per hour for April was $19.35.
1. Actual Labor Rate per Hour:
The labor price variance formula is:
Labor Price Variance = (Actual Labor Rate - Standard Labor Rate) x Actual Hours
We are given that the labor price variance for April was unfavorable and equal to $1,157. We also know that the standard labor rate was $20 per hour. Using the formula above and plugging in the known values, we can solve for the actual labor rate:
-1,157 = (Actual Labor Rate - 20) x 1,780
-1,157 = 1,780Actual Labor Rate - 35,600
1,780Actual Labor Rate = 34,443
Actual Labor Rate = 19.35
Therefore, the actual labor rate per hour for April was $19.35.
2. Standard Hours Allowed for the Output Achieved:
The flexible-budget variance formula is:
Flexible-Budget Variance = (Actual Hours - Standard Hours) x Standard Labor Rate
We are given that the flexible-budget variance for April was favorable and equal to $1,643. We also know that the standard labor rate was $20 per hour.
Using the formula above and plugging in the known values, we can solve for the standard hours allowed:
1,643 = (1,780 - Standard Hours) x 20
1,643 = 35,600 - 20Standard Hours
20Standard Hours = 33,957
Standard Hours = 1,697.85
Therefore, the standard hours allowed for the output achieved in April was 1,697.85.

Therefore , the solution of the given problem of probability comes out to be z-score from a typical normal distribution.
What exactly is probability?Any considerations technique's fundamental objective is to determine the likelihood that a claim is true or that a particular incident will take place. Any number range from one to one, when 0 traditionally signifies a percentage and 1 typically implies the degree of certainty, can be used to represent chance. A probability illustration shows the likelihood that a particular event will occur.
Here,
The formula for the standard error of the mean (SEM), which is as follows:
=> SEM = the standard deviation / √(sample size).
We can enter these numbers into the SEM calculation to determine the SEM given that the standard deviation of the tariff rates is $1200 and the sample size is 400:
=> SEM=$1200/√(400)
=> $1200/20 =$60
It is possible to calculate the z-score for a $80 departure from the mean with a $60 SEM as follows:
=> z = (80 - 0) / $60 = 1.3333
Now that we have the probability corresponding to the z-score of 1.3333,
we can look up the cumulative distribution function (CDF) of the standard normal distribution using a z-table or a statistical calculator.
The CDF depicts the likelihood that a random variable will occur is less than or equal to a certain z-score from a typical normal distribution.

Suppose you wish to borrow $400 for five weeks and the amount of interest you must pay is $25 per $100 borrowed. What is the APR at which you are borrowing money?
If we borrowed amount of $400 for 5 weeks, then the APR at which the money is borrowed is 260.71%.
First, we calculate the total interest paid for borrowing $400 for five weeks.
The interest rate is $25 per $100 borrowed, so for $400 borrowed, the interest paid is : $25 × 4 = $100,
So, the total amount that needs to be paid-back is $400 (the original borrowed amount) plus $100 (the interest paid) = $500,
Next, we can use the APR formula to calculate, which is
⇒ APR = (Interest Paid/Amount Borrowed)/(Number of days) × 365 × 100,
In this case, the total interest paid is $100 and the total amount borrowed is $400, and
The number of days amount is borrowed is = 5×7 = 35 days,
Substituting the values,
We get,
⇒ APR = (100/400)/35 ×365 × 100 ≈ 260.71%
Therefore, the APR at which the money is being borrowed is 260.71%.

Answer:
55.8° (nearest tenth)
Step-by-step explanation:
The angle of depression is the angle between the horizontal line of sight at the top of the treehouse and line of sight to the sandbox (the flight path of the paper airplane). (See attached diagram).
To find the angle of depression, we can use the cosine trigonometric ratio. The cosine of an angle is equal to the ratio of the length of the side adjacent the angle to the length of the hypotenuse.
[tex]\boxed{\begin{minipage}{9 cm}\underline{Cosine trigonometric ratio} \\\\$\sf \cos(\theta)=\dfrac{A}{H}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]
In this case, the length of the side adjacent the angle of depression is equal to the distance between the base of the tree and the sandbox, so A = 9 ft. The hypotenuse is the distance the airplane flies through the air, so H = 16 ft.
Substitute these values into the cosine ratio and solve for θ:
[tex]\cos (\theta)=\dfrac{9}{16}[/tex]
[tex]\theta=\cos^{-1}\left(\dfrac{9}{16}\right)[/tex]
[tex]\theta=55.7711336...^{\circ}[/tex]
[tex]\theta=55.8^{\circ}\; \sf (nearest \; tenth)[/tex]
Therefore, the angle of depression that the paper airplane is flying down at is 55.8° (nearest tenth).

An amusement park has three roller coasters, the "Falcon Flyer placed at (50, 300), the "Sprinter" placed at (400, 550), and the "Air Rider" placed at (800, 250). All measurements are in meters. You are at a point half way between the "Falcon Flyer" and the "Sprinter", see a long line, and decide to take a shortcut to the "Air Rider". How far will you walk on this shortcut if it follows a straight path? Round your answer to the nearest meter
Answer: 601 meters
Step-by-step explanation:
First, let's find the midpoint between the "Falcon Flyer" and the "Sprinter".
The x-coordinate of the midpoint is (50 + 400)/2 = 225.
The y-coordinate of the midpoint is (300 + 550)/2 = 425.
So the midpoint is (225, 425).
Now we need to find the distance between the midpoint and the "Air Rider". Using the distance formula:
d = sqrt[(800 - 225)^2 + (250 - 425)^2]
d = sqrt[(575)^2 + (-175)^2]
d = sqrt[330625 + 30625]
d = sqrt(361250)
d ≈ 601.041
So the distance you will walk on this shortcut is approximately 601 meters.
Given the following table of scores, calculate the indicated locator and percentile.
Do not round your results.
Here are the answers to the above questions:
Locator for the 52nd percentile, L52: 6.7252nd percentile, P52: 61.4Percentage of scores above the 52nd percentile: approximately 48%What is the explanation for the above response?To calculate the locator and percentile, we need to first arrange the scores in ascending order:
6, 8, 11, 12, 14, 17, 20, 34, 36, 38, 47, 48, 49
a) To calculate the locator for the 52nd percentile, we use the following formula:
Lp = (p/100) * (N + 1)
where Lp is the locator for the pth percentile, p is the percentile we are interested in, and N is the total number of scores.
For the 52nd percentile, p = 52 and N = 13. Substituting these values into the formula, we get:
L52 = (52/100) * (13 + 1) = 6.72
Therefore, the locator for the 52nd percentile is 6.72.
b) To determine the 52nd percentile, we need to find the score corresponding to the locator L52. Looking at the ordered list of scores, we see that the score at position 6 is 17 and the score at position 7 is 20. Since the locator L52 falls between positions 6 and 7, we can use linear interpolation to estimate the 52nd percentile:
P52 = (7 - L52) / (7 - 6) * 50 + (L52 - 6) / (7 - 6) * 50
P52 = (7 - 6.72) / (7 - 6) * 50 + (6.72 - 6) / (7 - 6) * 50
P52 = 38 + 0.48 * 50
P52 = 61.4
Therefore, the 52nd percentile is approximately 61.4.
c) To find the percentage of scores that are above the 52nd percentile, we subtract the 52nd percentile from 100:
100 - 52 = 48
Therefore, approximately 48% of the scores in the dataset are above the 52nd percentile.

A vending machines coin box contains nickels dimes and quarters. The total number of coins in the box is 292 the number of dimes is three times the number of nickels and quarters together at the box contains $29.95. find the number of nickels dimes and quarters that it contains.
There are 32 quarters, 225 dimes, and 53 nickels in the vending machine.
Let's denote the number of nickels by N, the number of dimes by D, and the number of quarters by Q.
From the first sentence, we know that:
N + D + Q = 292 (total number of coins)
From the second sentence, we know that:
D = 3(N + Q) (the number of dimes is three times the number of nickels and quarters together)
From the third sentence, we know that:
0.05N + 0.1D + 0.25Q = 29.95 (total value of the coins is $29.95)
Now we can substitute the second equation into the third equation to get:
0.05N + 0.1(3(N + Q)) + 0.25Q = 29.95
0.05N + 0.3N + 0.1Q + 0.25Q = 29.95
0.35N + 0.35Q = 29.95
N + Q = 85
We can now substitute this last equation into the first equation to get:
N + D + Q = 292
N + D + 85 = 292
N + D = 207
We can substitute the second equation into this last equation to get:
N + 3(N + Q) = 207
4N + 3Q = 207
We can now solve the system of equations consisting of the last two equations we derived:
N + Q = 85
4N + 3Q = 207
Multiplying the first equation by 4 and subtracting it from the second equation:
4N + 3Q - 4(N + Q) = 207 - 4*85
-N = -53
N = 53
Substituting this value into the equation N + Q = 85:
53 + Q = 85
Q = 32
Finally, we can use the equation D = 3(N + Q) from earlier to find the value of D:
D = 3(N + Q)
D = 3(53 + 32)
D = 225
Therefore, the vending machine contains 53 nickels, 225 dimes, and 32 quarters.

Explain about the proportional relationship:A connection among two factors that changes proportionally is referred to as a proportional relationship. If y=kx, where k is just the proportionality constant, can be used to represent two quantities, x and y, then they are said to be proportional.
This implies that the ratio between both always remains the same and that as x increases, y increases, and as x drops, y decreases.The proportional connection equation's graph is a line that passes directly through the origin.From the given options, consider the table:
x 7 14 28 35
y 1 2 4 5
As per proportional relationship.:
y=kx
k = y/x (must be same in all cases)
k = 1/7
k = 14/2 = 1/7
k = 4/28 = 1/7
k = 5/35 = 1/7

What is the volume of the triangular prism
below?5 cm 3 cm 4 cm 3 cm pls show work
The volume of the triangular prism as shown in the attached image is 30 cm³.
Showing the working for volume of triangular prismTo find the volume of a triangular prism, we need to multiply the area of the triangular base by the height of the prism.
The area of the triangular base can be found using the formula:
Area = (1/2) × base × height
In this case, the base is 5 cm and the height is 4 cm, so the area of the triangular base is:
Area = (1/2) × 5 cm × 4 cm = 10 cm²
The height of the prism is 3 cm.
Therefore, the volume of the triangular prism is:
Volume = Area of triangular base × height
= 10 cm² × 3 cm
= 30 cm³

Lester Hollar is vice president for human resources for a large manufacturing company. In recent years, he has noticed an increase in absenteeism that he thinks is related to the general health of the employees. Four years ago, in an attempt to improve the situation, he began a fitness program in which employees exercise during their lunch hour. To evaluate the program, he selected a random sample of eight participants and found the number of days each was absent in the 6 months before the exercise program began and in the 6 months following the exercise program. Following are the results.
Employee Before After
1 8 7
2 7 3
3 8 2
4 8 4
5 6 5
6 7 10
7 6 4
8 8 9
At the 0.050 significance level, can he conclude that the number of absences has declined?
a. Compute the test statistic.
b. Compute the p-value.
The p-value can also be calculated using a t-distribution table or a statistical software package. Using a two-tailed test with 7 degrees of freedom and a significance level of 0.05, we obtain a p-value of 0.073.
How to solve the question?
To determine whether the fitness program has had a significant effect on reducing employee absenteeism, we need to conduct a hypothesis test.
Null hypothesis: The average number of absences before and after the fitness program are the same.
Alternative hypothesis: The average number of absences after the fitness program is less than before the program.
To test this hypothesis, we can use a one-tailed paired t-test with a significance level of 0.05. We will calculate the difference between the number of absences before and after the program for each employee, and then compute the mean and standard deviation of the differences. The t-test statistic will then be calculated as the mean difference divided by the standard deviation of the differences, multiplied by the square root of the sample size.
Using the given data, we calculate the differences and obtain the following results:
Employee Before After Difference (d) d²
1 8 7 -1 1
2 7 3 -4 16
3 8 2 -6 36
4 8 4 -4 16
5 6 5 -1 1
6 7 10 3 9
7 6 4 -2 4
8 8 9 1 1
Mean difference (d-bar) = -1.25
Standard deviation of differences (s) = 3.27
Sample size (n) = 8
The t-test statistic can now be calculated as:
t = (d-bar / (s / √(n))) = (-1.25 / (3.27 / √(8))) = -1.63
The degrees of freedom for the t-test is n-1 = 7, which can be used to obtain the p-value from a t-table or calculator. Using a one-tailed test with a significance level of 0.05 and 7 degrees of freedom, the critical t-value is -1.895.
Since our calculated t-value (-1.63) is greater than the critical t-value (-1.895), we fail to reject the null hypothesis. In other words, we do not have sufficient evidence to conclude that the fitness program has resulted in a significant reduction in employee absenteeism.
The p-value can also be calculated using a t-distribution table or a statistical software package. Using a two-tailed test with 7 degrees of freedom and a significance level of 0.05, we obtain a p-value of 0.073. Since this p-value is greater than the significance level, we again fail to reject the null hypothesis.

Miss Johnson's guests were to arrive at 6:15 P.M., but because of a bad storm they were 2/5 of an hour late. What time did they arrive for dinner?
the guests arrived for dinner at 6:39 P.M.which is solved by according to given question.
How to solve the question?
To solve this problem, we need to first convert the fraction of an hour that Miss Johnson's guests were late into minutes. We know that 1 hour is equal to 60 minutes, so we can find the number of minutes the guests were late by multiplying 2/5 by 60:
2/5 hour * 60 minutes/hour = 24 minutes
So the guests were 24 minutes late. To find out what time they arrived, we need to add 24 minutes to the original arrival time of 6:15 P.M.:
6:15 P.M. + 24 minutes = 6:39 P.M.
Therefore, the guests arrived for dinner at 6:39 P.M.
It's important to note that fractions can often be confusing when dealing with time calculations. In this case, we converted the fraction of an hour to minutes to make the calculation easier. Additionally, it's always a good idea to double-check your work to ensure that your answer makes sense in the context of the problem.
