The area of the shaded rectangle is 18 square units.

The shaded region is the framed rectangle, and the white part is the frame.

We know that the frame is 2 units wide, and the measure of the rectangle and the frame are:

Now, if we remove the frame, we will remove 2*2 units = 4 units for each measure (because for each measure we have the frame in both sides).

So the measures for the shaded rectangle are:

And the area of a rectangle is given by the product between the width and length, then we have:

A = (3 units)*(6 units) = 18 square units.

Answer:

\( \boxed{3x\degree = 30\degree} \)

Explanation:

Vertically opposite angles are equal.

Nadia was 1cm off the actual measurement of 5 cm. That is a percent error of 20%.

Sasha was 4 cm off the actual measurement of 100 cm. That’s a percent error of 4%.

From the information, the measurement was 4cm and the actual measurement was 5cm. Therefore, the difference will be:

= 5cm - 1cm

= 4cm

The percentage error will be:

= Difference in measurement / Actual measurement × 100

= 1/5 × 100

= 20%.

The percentage error for Sasha will be:

= 4/100 × 100

= 4%

A. The average number of minutes per day spent moving these products using the static storage policy is 1.33 minutes.

B.  The lowest value of average minutes per day used to move these SKUs with the heap policy is approximately 1.17 minutes per day. The initial placement of the SKUs does make a difference in determining the lowest average movement time, as shown by the difference between Scenario 1 and Scenario 2.

a. Static Storage Policy:

To minimize labor, we can allocate the SKUs to storage locations based on their respective travel times from the receiving area to the storage area. In this case, the travel times are 1 minute for location A, 2 minutes for location B, and 2 minutes for location C.

Given that we maintain a constant inventory of one pallet of SKU x and two pallets of SKU y at all times, we can allocate them as follows:

SKU x: Allocate it to the storage location with the shortest travel time, which is location A (1 minute).

SKU y: Allocate both pallets to the storage location with the next shortest travel time, which is location B or C (both have a travel time of 2 minutes).

By allocating SKU x to location A and both pallets of SKU y to either location B or C, we ensure that the SKUs are stored in the closest available locations, minimizing the travel time needed to move them.

The average number of minutes per day spent moving these products can be calculated by considering the dispatch and receiving schedule:

SKU x: Dispatched every three days. Assuming it takes 1 minute to move a pallet from storage to the receiving area, the average daily movement time for SKU x would be (1/3) minutes per day.

SKU y: Dispatched every two days. Assuming it takes 2 minutes to move a pallet from storage to the receiving area, the average daily movement time for SKU y would be (2/2) minutes per day.

Adding up the average daily movement times for SKU x and SKU y, we get:

Average daily movement time = (1/3) + (2/2) = 1.33 minutes per day.

Therefore, the average number of minutes per day spent moving these products using the static storage policy is 1.33 minutes.

b. Heap Policy:

The heap policy involves storing the most frequently dispatched SKU closest to the receiving area. In this case, SKU y is dispatched every two days, while SKU x is dispatched every three days.

To find the lowest value of average minutes per day used to move these SKUs with the heap policy, we need to consider the different initial placements of the SKUs.

Scenario 1: Initial Placement - Location A for SKU x and Location B for SKU y

SKU x: Travel time from storage to the receiving area = 1 minute

SKU y: Travel time from storage to the receiving area = 2 minutes

Average daily movement time:

SKU x: (1/3) minutes per day

SKU y: (2/2) minutes per day

Total average daily movement time = (1/3) + (2/2) = 1.33 minutes per day

Scenario 2: Initial Placement - Location A for SKU y and Location B for SKU x

SKU y: Travel time from storage to the receiving area = 1 minute

SKU x: Travel time from storage to the receiving area = 2 minutes

Average daily movement time:

SKU y: (1/2) minutes per day

SKU x: (2/3) minutes per day

Total average daily movement time = (1/2) + (2/3) ≈ 1.17 minutes per day

Therefore, the lowest value of average minutes per day used to move these SKUs with the heap policy is approximately 1.17 minutes per day. The initial placement of the SKUs does make a difference in determining the lowest average movement time, as shown by the difference between Scenario 1 and Scenario 2.

Answer and Step-by-step explanation:

We want to prove that 0.5555... = 5/9.

First, let's set 0.555... equal to x:

x = 0.555...

Now multiply this by 10:

10x = 5.555...

Now subtract the original from this new one:

   10x = 5.555...

-       x = 0.555...

______________

     9x = 5

Note that we could cancel all the recurring terms because they were the same for both 5.555... and 0.555... since the 5's go up to infinity.

We now have 9x = 5, so divide both sides by 9:

x = 5/9, as desired

I agree with your disagreement with the student's claim because the percent increase in the average price per gallon of gasoline for the two-year periods from 2011 to 2013 and from 1998 to 2000 is not the same.

To determine if the student's claim about the percent increase in the average price per gallon of gasoline is correct, we need to compare the two-year periods from 2011 to 2013 and from 1998 to 2000.

First, let's calculate the percent increase for each period. We'll use the formula:

Percent increase = [(New Value - Old Value) / Old Value] * 100For the two-year period from 2011 to 2013:

Percent increase = [(3.814 - 1.354) / 1.354] * 100 ≈ 181.66%For the two-year period from 1998 to 2000:

Percent increase = [(1.291 - 1.354) / 1.354] * 100 ≈ -4.64%

As we can see, the percent increase for the two-year period from 2011 to 2013 is approximately 181.66%, while the percent increase for the two-year period from 1998 to 2000 is approximately -4.64%. These values are significantly different, indicating that the student's claim is incorrect.

The minimum sample size needed assuming that no prior information is available is 667. Hence, n = 667.

Here are the steps to calculate the minimum sample size needed assuming that no prior information is available:

Given that the researcher wishes to estimate, with 99% confidence, the population proportion of motor vehicle fatalities that were caused by alcohol-impaired driving, and his estimate must be accurate within 4% of the population proportion.

Now, to calculate the minimum sample size needed when there is no prior information available, we use the formula for the sample size for proportions;

n = (zα/2/ E)²P (1 - P)

where n is the minimum sample size, zα/2 is the z-score for the confidence level, E is the margin of error, and P is the estimated proportion of the population that has the attribute of interest.

Confidence level = 99%,

hence the corresponding z-score (zα/2) = 2.58

Margin of error (E) = 4%

= 0.04

P = 0.5 (assuming the worst-case scenario, where the proportion of interest is 50%, which gives the maximum value for the sample size)

Now, we can substitute the values in the formula;

n = (zα/2/ E)²P (1 - P)

n = (2.58/0.04)²(0.5)(0.5)

n = 666.42

The minimum sample size needed assuming that no prior information is available is 667. Hence, n = 667.

Answer:

the answer is -90degrees

Step-by-step explanation:

DO substitite 180 for  pie and do -180/2 and get -90 degrees

The z-scores for the 10th and 90th percentiles are -1.28 and 1.28, respectively. The mean and standard deviation of the performance scores can be determined using the z-scores and the z-score formula.

a. To find the z-scores associated with the 10th and 90th percentiles from the standard normal distribution, we can use a standard normal distribution table or a calculator. The 10th percentile corresponds to a z-score of approximately -1.28, and the 90th percentile corresponds to a z-score of approximately 1.28.

b. To calculate the mean and standard deviation of the performance scores, we can use the z-score formula and the information given. Let's denote the mean as μ and the standard deviation as σ.

For the 10th percentile (z = -1.28):

-1.28 = (380 - μ) / σ

For the 90th percentile (z = 1.28):

1.28 = (160 - μ) / σ

Solving these two equations simultaneously will give us the values of μ and σ.

c. To find the performance score a manager must exceed to receive an A grade, we need to find the z-score associated with the top 3% of the standard normal distribution. The z-score corresponding to the top 3% is approximately 1.88. Using the z-score formula, we can calculate the corresponding performance score:

1.88 = (X - μ) / σ

Solving this equation for X will give us the performance score needed to receive an A grade.

Objective Function and Constraints:

Let:

x1 = amount spent on food

x2 = amount spent on shelter

x3 = amount spent on entertainment

Objective Function:

Maximize: 2x1 + 3x2 + 5x3 (since each dollar spent on food has a satisfaction value of 2, each dollar spent on shelter has a satisfaction value of 3, and each dollar spent on entertainment has a satisfaction value of 5)

Constraints:

Subject to:

x1 + x2 + x3 ≤ $1,500 (maximum disposable income)

x1 + x2 ≤ $1,100 (amount spent on food and shelter combined must not exceed $1,100)

x2 ≤ $800 (amount spent on shelter alone must not exceed $800)

x3 ≤ $400 (entertainment cannot exceed $400)

Using Excel Solver:

In Excel, set up a spreadsheet with the following columns:

Column A: Variable names (x1, x2, x3)

Column B: Objective function coefficients (2, 3, 5)

Column C: Constraints coefficients (1, 1, 1) for the first constraint (maximum disposable income)

Column D: Constraints coefficients (1, 1, 0) for the second constraint (amount spent on food and shelter combined)

Column E: Constraints coefficients (0, 1, 0) for the third constraint (amount spent on shelter alone)

Column F: Constraints coefficients (0, 0, 1) for the fourth constraint (entertainment limit)

Column G: Right-hand side values ($1,500, $1,100, $800, $400)

Apply the Excel Solver tool with the objective function and constraints to find the optimal allocation of funds.

Once the Excel Solver completes, it will report the maximum value of the objective function, which represents the optimal satisfaction value achieved within the given budget constraints.
