The cost of sales for liquor, expressed as a percentage is 19.39%.

To compute for the cost of sales for liquor, expressed as a percentage given that you have spent $2,500 on liquor for your bar and your bar sales have been $12,890, you can use the formula:

Cost of sales = (Cost of Goods Sold / Total Sales) × 100

where, Cost of Goods Sold (COGS) = Beginning Inventory + Purchases - Ending Inventory (or the total cost of goods sold during the period)

Total Sales = Gross sales - Sales discounts - Sales returns and allowances

Let's compute for the COGS first:

COGS = Beginning Inventory + Purchases - Ending Inventory

= $0 + $2,500 - $0

= $2,500

Total Sales = Gross sales - Sales discounts - Sales returns and allowances

= $12,890 - $0 - $0

= $12,890

Cost of sales is obtained as follows:

Cost of sales = (Cost of Goods Sold / Total Sales) × 100

= ($2,500 / $12,890) × 100

= 19.39%.

Therefore, the cost of sales for liquor, expressed as a percentage is 19.39%.

The production manager's claim that no more than 4,000 insulating washers are defective per day is likely to be true, based on the sample of 200 washers.

Proportion refers to the relationship between two quantities or numbers, indicating how they are related to each other in size or amount.

To determine whether the production manager's claim is likely to be true, we can use hypothesis testing. We can formulate the following hypotheses:

Null hypothesis (H0): The true proportion of defective insulating washers is equal to or less than 0.02 (4,000/225,000).

Alternative hypothesis (Ha): The true proportion of defective insulating washers is greater than 0.02.

We can use a significance level of 0.05, which means we are willing to accept a 5% chance of rejecting the null hypothesis when it is actually true.

To test these hypotheses, we need to calculate the test statistic and p-value. We can use the normal approximation to the binomial distribution, since the sample size (200) is large enough and the proportion of defective washers is relatively small (0.02).

The test statistic is calculated as:

z = (0.02 - 0.02) / √(0.02×(1-0.02)/200) = 0

The p-value is the probability of getting a test statistic as extreme or more extreme than the one observed, assuming the null hypothesis is true. Since we are testing the alternative hypothesis that the true proportion of defectives is greater than 0.02, we need to calculate the right-tailed p-value. We can use a standard normal distribution to calculate the p-value:

p-value = P(Z > z) = P(Z > 0) = 0.5

We are unable to reject the null hypothesis since the p-value is higher than the significance level of 0.05. This means we do not have sufficient evidence to conclude that the true proportion of defective insulating washers is greater than 0.02.

Therefore, the production manager's claim that no more than 4,000 insulating washers are defective per day is likely to be true, based on the sample of 200 washers.

Step-by-step explanation:

Cant really graph since we don't have access, but here are some pointers.

Answer:

To find out how many bushes are in each row, we need to use the information given in the problem. We know that there are a total of 15 bushes at the entrance to the park, and the garden contains the same number of bushes in each row. Therefore, we can subtract the 15 bushes at the entrance from the total number of bushes in the garden to find out how many bushes are in the rows:

Total number of bushes in the garden = Number of rows × Number of bushes in each row

Total number of bushes in the garden = 4 × Number of bushes in each row

So, we can write:

4 × Number of bushes in each row - 15 = Number of bushes in the garden

We are not given the total number of bushes in the garden, but we can use algebra to solve for the number of bushes in each row:

4 × Number of bushes in each row - 15 = Number of bushes in the garden

4 × Number of bushes in each row - 15 = 35 (since there are 15 bushes at the entrance to the park, the total number of bushes in the garden is 35)

4 × Number of bushes in each row = 50

Number of bushes in each row = 50 ÷ 4

Number of bushes in each row = 12.5

Since the number of bushes in each row must be a whole number, we can round up to get:

Number of bushes in each row = 13

Therefore, each row in the garden has 13 azalea bushes.

Answer: 60?

Step-by-step explanation:

The reference angle is the acute angle formed between the terminal side of an angle in standard position and the x-axis. To find the reference angle of an angle, you can follow these steps:

Determine the quadrant in which the angle terminates. For -60 degrees, this would be the fourth quadrant.

Determine the corresponding angle in the first quadrant by finding the angle formed between the terminal side and the x-axis. In the fourth quadrant, this angle is equal to 360 degrees minus the original angle. So for -60 degrees, the corresponding angle in the first quadrant is 360 - 60 = 300 degrees.

Subtract this angle from 360 degrees to find the reference angle. For -60 degrees, the reference angle is 360 - 300 = 60 degrees.

Therefore, the reference angle of -60 degrees is 60 degrees.

Let's use the variable "s" to represent the number of slices in each pizza.

The drama club bought 999 large pizzas, and each pizza had s slices. So, the total number of pizza slices is given by the product of 999 and s, which can be written as:

999s = 727272

To solve for s, we can divide both sides of the equation by 999:

s = 727272/999

Using a calculator, we can simplify this fraction to:

s ≈ 728.73

Therefore, each pizza has approximately 728 slices. Note that this is an unusual number of slices for a pizza, so it's possible that the problem is not intended to be taken literally, but rather as a math puzzle or word problem.

The number of receptacles required in the classroom is 14.

To determine the number of receptacles required in a classroom, we need to consider the electrical code requirements for the room size and layout.

According to the National Electrical Code (NEC), there should be at least one duplex receptacle for every 12 linear feet of wall space in a classroom.

In addition, there should be at least one receptacle within 6 feet of each doorway and at least one receptacle on each wall space that is 2 feet or more in width.

Using this information and the dimensions provided, we can calculate the required number of receptacles as follows:

Calculate the perimeter of the room:

Perimeter = 2(Length + Width) = 2(36 + 24) = 120 feet

Calculate the total linear feet of wall space:

Total wall space = Perimeter - Width of door = 120 - 3 = 117 feet

Determine the number of receptacles required:

Number of receptacles = Total wall space / 12 + Number of doorways + Number of wall spaces wider than 2 feet

Number of doorways = 1 (as stated in the question)

Number of wall spaces wider than 2 feet = 2 (the two 24-foot-long walls)

Answer: 240 miles in 2 hours

Step-by-step explanation:

we know the car is traveling 60 km per half hour (30 minutes)

so to find km per hour, multiply both by 2.

the rate of speed is 120 miles per 60 minutes (1 hour)

multiply 120 mph by the 2 hours given = 240 miles in 2 hours

Answer:

240 km in 2 hours

Step-by-step explanation:

If the car travels 60 km in 30 minutes, then its speed can be calculated as follows:

Speed = distance ÷ time

Speed = 60 km ÷ (30 minutes ÷ 60) = 120 km/hour

Since the car is traveling at a constant speed, we can use the formula:

Distance = Speed × Time

To find how far the car will travel in 2 hours, we can substitute the values we have found:

Distance = Speed × Time

Distance = 120 km/hour × 2 hours

Distance = 240 km

Therefore, the car will travel 240 km in 2 hours if it continues at the same constant speed.

The dollar interval that would give a probability of 0.500 is X ± $8.47.

To determine the dollar interval that would give a probability of 0.500, we need to calculate the confidence interval using the formula:

Confidence interval = X ± Zα/2 × σ/√n

where:

X = sample mean

Zα/2 = Z-score for the desired level of confidence (in this case, 0.500 corresponds to a Z-score of 1.96)

σ = population standard deviation

n = sample size

Substituting the given values, we have:

Confidence interval = X ± 1.96 × 80/√64

Confidence interval = X ± 19.6

Since we want a probability of 0.500, we need to find the z-scores that correspond to the middle 50% of the normal distribution. Using a standard normal table, we can find that the z-scores are approximately -0.6745 and +0.6745.

Therefore, the confidence interval that will give a probability of 0.500 is:

X ± 0.6745 × 80/√64

X ± 8.47

So, when presenting the Q2 Sales Report to management, we would have to provide a dollar interval of X ± $8.47 to obtain a probability of 0.500.
