The coordinates of the intersection of the diagonals are CD.

Answer:

I assume you mean the volume. V = (pi)(125)/6 cm³

Step-by-step explanation:

h = 10 cm

r = d/2 = 5/2 = 2.5 cm

volume = pi(r)(r)(h)/3

V = pi(2.5)(2.5)(10)/3 = (pi)(125/6)

Answer:

12x + 22

Step-by-step explanation:

3(6x+4) -2(3x-5)

= 18x + 12 - 6x + 10

= 12x + 22

So, the answer is 12x + 22

Answer:

To find the area of the rectangular window in square inches, we need to convert the dimensions from feet to inches. Since there are 12 inches in a foot, we can multiply the length and width of the window by 12 to get the measurements in inches.

Length of the window: 4 ft * 12 in/ft = 48 inches

Width of the window: 2 ft * 12 in/ft = 24 inches

Now, we can calculate the area of the window by multiplying the length and width:

Area = Length * Width

Area = 48 inches * 24 inches

Area = 1152 square inches

Therefore, the area of the rectangular window is 1152 square inches.

The sample mean is 24.67 mins while the population means is 27 mins. The estimated margin of error of the sample population is 5.32 mins.

a) Sample mean and the Population mean:

Sample Mean:

Sample mean is the sum of all the commute time and dividing it by the number of selected employees.

Sample mean (Xbar) = (31 + 10 + 13 + 42 + 20 + 23 + 23 + 27 + 25 + 31 + 18 + 13) / 12

          = 296 / 12

          = 24.67 minutes

Population Mean:

The population mean is the average of all possible values in the entire population. However, from the question, we are given the  population mean to be 27min

Population mean = 27 minutes

b) Margin of error of the sample population using the standard deviation:

Standard Deviation (s):

The standard deviation of a sample measures the average distance of individual data points from the sample mean.

Step 1: Calculate (X - Xbar):

(31 - 24.67),

(10 - 24.67),

(13 - 24.67),

(42 - 24.67),

(20 - 24.67),

(23 - 24.67),

(23 - 24.67),

(27 - 24.67),

(25 - 24.67),

(31 - 24.67),

(18 - 24.67),

(13 - 24.67)

Step 2: Calculate (X - Xbar)²:

44.11, 214.52, 130.38, 321.89, 22.11, 1.62, 1.62, 4.72, 0.18, 44.11, 40.18, 130.38

Step 3: Sum up the squared differences:

Sum = 44.11 + 214.52 + 130.38 + 321.89 + 22.11 + 1.62 + 1.62 + 4.72 + 0.18 + 44.11 + 40.18 + 130.38

    = 974.82

Step 4: Divide by the sample size minus 1:

s = √(974.82 / (12 - 1))

  ≈ √(974.82 / 11)

  ≈ √88.62

  ≈ 9.41 minutes

Margin of Error:

The margin of error is calculated by multiplying the standard deviation by a critical value, which depends on the desired level of confidence. For a 95% confidence level, the critical value is approximately 1.96.

Margin of error = 1.96 * (s / √n)

              = 1.96 * (9.41 / √12)

              ≈ 1.96 * (9.41 / 3.464)

              = 5.32 minutes

The equation f(x) = k * (x + 2) / [(x - 5) * (x - 1)] could represent the given rational function with an x-intercept at (-2, 0) and vertical asymptotes at x = 5 and x = 1.

To write an equation that represents the given rational function with an x-intercept at (-2, 0) and vertical asymptotes at x = 5 and x = 1, we can start by considering the factors in the numerator and denominator of the function.

Since the function has an x-intercept at (-2, 0), it means that the numerator of the function has a factor of (x + 2).

Since the function has vertical asymptotes at x = 5 and x = 1, it means that the denominator of the function has factors of (x - 5) and (x - 1).

Putting these factors together, the equation that could represent this function is:

f(x) = k * (x + 2) / [(x - 5) * (x - 1)]

Here, k represents a constant multiplier that scales the function, and it can be any non-zero constant value.

The dimensions of the lot that maximize the enclosed area are 150 meters in width and 300 meters in length.

To find the dimensions of the lot that maximize the enclosed area, we can use the concept of calculus and optimization.

Let the width of the lot as 'w' and the length of the lot as 'l.'

Given that the lot is bordered on one side by a stream and on the other three sides by 600m of fencing,

we can set up the equation for the perimeter of the lot:

Perimeter = 600m

Since the length of the lot is bounded by the stream and the width is bounded by the remaining three sides, we have:

Length (l) + 2 × Width (w) = 600m

We may use the constraint equation to solve for one variable in terms of the other since we need to represent the area of the lot in terms of just one variable.

l = 600m - 2w

The area (A) of the lot is given by:

A = Length × Width

Substituting the value of l from the constraint equation, we have:

A = (600m - 2w) × w

A = 600w - 2w²

To find the maximum area, we differentiate A with respect to w and set it equal to zero:

dA/dw = 600 - 4w = 0

Solving this equation, we find:

4w = 600

w = 150m

Substituting the value of w back into the constraint equation, we can solve for l:

l = 600m - 2(150m)

l = 300m

Therefore, the dimensions of the lot that maximize the enclosed area are 150 meters in width and 300 meters in length.

All three approaches yield the same result: AED4,600,000 (Expenditure Approach), AED1,600,000 (Income Approach), and AED1,800,000 (Production Approach). This consistency demonstrates that the three approaches provide equivalent measures of GDP.

To calculate the contributions to GDP of the given transactions, we can use the three approaches: the expenditure approach, income approach, and production approach. Let's calculate the GDP using each approach and demonstrate that they give the same answer.

Expenditure Approach:

GDP is calculated as the sum of all final expenditures. In this case, the final expenditures are the sales of the supercomputers.

GDP = Sales of supercomputers

= (3 * AED1,000,000) + (1 * AED800,000)

= AED3,800,000 + AED800,000

= AED4,600,000

Income Approach:

GDP can also be calculated by summing up all the incomes earned during production. In this case, the incomes include wages, interest, and taxes.

GDP = Wages + Interest + Taxes

= (Labour costs for ABC + Labour costs for Jumbo) + (Interest on debt for ABC) + (Taxes for ABC + Taxes for Jumbo)

= (AED1,000,000 + AED200,000) + AED100,000 + (AED200,000 + AED100,000)

= AED1,200,000 + AED100,000 + AED300,000

= AED1,600,000

Production Approach:

GDP can also be calculated by summing the value added at each stage of production. In this case, the value added is the sales price minus the cost of components purchased.

GDP = Sales price of supercomputers - Cost of components

= (3 * AED1,000,000) + (1 * AED800,000) - (4 * AED500,000)

= AED3,000,000 + AED800,000 - AED2,000,000

= AED1,800,000

As we can see, all three approaches yield the same result: AED4,600,000 (Expenditure Approach), AED1,600,000 (Income Approach), and AED1,800,000 (Production Approach). This consistency demonstrates that the three approaches provide equivalent measures of GDP.

To convert caster sugar from grams to cups, you can use the fact that 1 cup of caster sugar is equivalent to approximately 200 grams. So, to convert a given amount of caster sugar in grams to cups, you can divide the number of grams by 200.

For example, if you have 400 grams of caster sugar, you can convert it to cups by dividing 400 by 200, which gives you 2 cups.

It's important to note that this conversion is an approximation and can vary slightly depending on factors such as the density of the sugar and how tightly it is packed into the cup. For more precise measurements, it's always a good idea to use a kitchen scale to weigh ingredients.

Answer: B. Yellow

Step-by-step explanation: Yellow has the largest number of students out of the entire data set, so it will consume the largest area on a pie chart.

Answer:

A pie chart is a type of graph that shows the relative sizes of different categories of data by dividing a circle into sectors or slices. Each sector represents a fraction of the whole circle, which is equal to 100%. The angle of each sector is proportional to the percentage of the data it represents. To answer a question based on a pie chart, we need to compare the sizes of the sectors and find the one that matches the given condition.

For example, consider the following question:

When asked their favorite color, 20 students said red, 23 students said blue,

25 students said green, and 28 students said yellow. Students with which

favorite color would be represented by the largest wedge in a pie chart?

To answer this question, we need to find the total number of students who participated in the survey. We can do this by adding up the numbers of students who chose each color:

20 + 23 + 25 + 28 = 96

Next, we need to find the percentage of students who chose each color by dividing the number of students by the total and multiplying by 100:

Red: (20 / 96) x 100 = 20.83%

Blue: (23 / 96) x 100 = 23.96%

Green: (25 / 96) x 100 = 26.04%

Yellow: (28 / 96) x 100 = 29.17%

Finally, we need to compare the percentages and find the largest one. In this case, it is yellow with 29.17%. Therefore, students who chose yellow as their favorite color would be represented by the largest wedge in a pie chart.

The answer is B. Yellow.

Step-by-step explanation:

B is the only choice of graph that matches the inequality x²≥4

The magnitude of the vector sum (A + B) is approximately 4.974.

To find the magnitude of the vector sum (A + B), we need to add the corresponding components of vectors A and B and then calculate the magnitude of the resulting vector.

Given:

Vector A: (5.1, 0)

Vector B: (-2.6, -4.3)

To find the vector sum (A + B), we add the corresponding components:

(A + B) = (5.1 + (-2.6), 0 + (-4.3))

= (2.5, -4.3)

Now, let's calculate the magnitude of the vector (2.5, -4.3):

Magnitude = sqrt((2.5)^2 + (-4.3)^2)

= sqrt(6.25 + 18.49)

= sqrt(24.74)

After wearing blue shirts on Monday, Tuesday, and Wednesday, there are 2 blue shirts remaining in the closet.

There are a total of 13 - 3 = 10 shirts remaining in the closet.

Out of the remaining shirts, there are 3 green shirts and 5 red shirts, for a total of 8 shirts.

Since you are not allowed to wear the same shirt twice, and you have already worn 3 blue shirts, you have worn a total of 3 shirts.

Therefore, you have 10 - 3 = 7 shirts remaining in the closet.

Since you have 7 shirts remaining, and you can wear one shirt each day for the rest of the week, you can wear a different shirt each day from Thursday to Sunday.

Therefore, the number of different ways you can wear a shirt for the entire week, without wearing the same shirt twice, is:

3 (for Monday, Tuesday, and Wednesday) x 3 (remaining blue shirts) x 4 (for Thursday, Friday, Saturday, and Sunday) = 36.

Answer:

80.55

Step-by-step explanation:

Formula to calculate the perimeter (P) of a regular dodecagon with a radius (r) is:

P = 24 * r * sin(π/12),

where π is approximately 3.14159.

Using this formula, with the given radius of 13, we can calculate the perimeter as follows:

P = 24 * 13 * sin(π/12).

Calculating sin(π/12), we find that it is approximately 0.2588190451.

Substituting this value into the formula, we have:

P = 24 * 13 * 0.2588190451.

Evaluating the expression, we get:

P ≈ 80.55223123.

Therefore, the approximate perimeter of a regular dodecagon with a radius of 13 is approximately 80.55 units.

Perimeter = 12 × 13 × sin(π/12) ≈ 121.41 units

regular dodecagon with a radius of 13.

A regular dodecagon can be divided into 12 congruent isosceles triangles, each with a central angle of 30 degrees (360 degrees divided by 12 sides). The base of each triangle is a side of the dodecagon, and the two equal sides are radii of the dodecagon.

To find the length of the base of each triangle (i.e., the side of the dodecagon), we can use trigonometry. The formula is:

base = 2 * radius * sin(π/12),

where radius is 13 and π is approximately 3.14159.

Substituting the given values into the formula, we have:

base = 2 * 13 * sin(π/12).

Calculating sin(π/12), we find that it is approximately 0.2588190451.

Now we can substitute this value into the formula:

base = 2 * 13 * 0.2588190451.

Evaluating the expression, we get:

base ≈ 6.712685936.

Since there are 12 sides in the dodecagon, the perimeter is the sum of all the sides:

perimeter = 12 * base.

Substituting the value of the base, we have:

perimeter = 12 * 6.712685936.

Calculating the expression, we find:

perimeter ≈ 80.55223123.

Therefore, the approximate perimeter of a regular dodecagon with a radius of 13 is approximately 80.55 units
