To divide 30 into five parts such that the first and last parts are in the ratio of 2:3, we can follow these steps:

1. Determine the ratio between the first and last parts. In this case, it is 2:3.

2. Add the ratio values together to find the total number of parts: 2 + 3 = 5.

3. Divide the total value (30) by the total number of parts (5) to find the value of each part: 30 / 5 = 6.

4. Multiply the value of each part by the respective ratio values to obtain the individual parts:

- First part: 2 * 6 = 12

- Second part: 6

- Third part: 6

- Fourth part: 6

- Last part: 3 * 6 = 18

Therefore, the five parts of 30, with the first and last parts in the ratio of 2:3, are 12, 6, 6, 6, and 18.

The total materials handling cost allocated to the modular homes is $246,372.84.

The total materials handling cost allocated to the Prefab Barns is closest to $108,000.

To allocate materials handling cost based on material moves, we must determine proportion of material moves for each product and then apply that proportion to the total materials handling cost.

Proportion of material moves for Modular Homes:

= (Total expected material moves for Modular Homes) / (Total expected material moves for both products)

= 590 / (590 + 190)

= 0.756

Total materials handling cost allocated to Modular Homes:

= Proportion of material moves for Modular Homes * Total materials handling cost

= 0.756 * $325,890

= 246 372.84

= $246,372.84.

To allocate the materials handling cost based on direct labor-hours, we need to determine proportion of direct labor-hours for each product.

For Modular Homes:

Total direct labor-hours for Modular Homes:

= 6,000 units * 800 hours/unit

= 4,800,000 hours

For Prefab Barns:

Total direct labor-hours for Prefab Barns:

= 9,000 units * 300 hours/unit

= 2,700,000 hours

Total direct labor-hours for both products:

= 4,800,000 hours + 2,700,000 hours

= 7,500,000 hours

Proportion of direct labor-hours for Prefab Barns:

= 2,700,000 hours / 7,500,000 hours

= 0.36

Allocated materials handling cost for Prefab Barns:

= Proportion of direct labor-hours for Prefab Barns * Total materials handling cost

= 0.36 * $300,000

= $108,000.

Answer:

B.

Step-by-step explanation:

The answer is B.  If you go down from the y intercept 2 times, and then to the right 3 times, you get to the x intercept.

Answer: y = -2/3x + 2

Step-by-step explanation:

The graph shows a constant negative slope and also has a y-intercept.

The y-intercept is the point that intersects the y axis. We see that the point (0,2) intersects the y- axis, and we can use the positive value 2 at the end of equation of a line:  y = mx + b

# = number

The slope is rise/run, or the # of y/# of x -> 2/3

since the slope is going downward, the slope would be negative -> -2/3

So the equation of the line is : y = -2/3x + 2

Answer:

Perimeter:\(4x+10\) feet
Area:\(x^{2}+5x+6\) feet

Step-by-step explanation:

The perimeter is equal to 2*width +2*length. The width is x+2 and the length is x+3, therefore the perimeter is equal to 2x+4+2x+6 which equals 4x+10.
The area is equal to width*length
(x+3)(x+2)=\(x^{2}+2x+3x+6=x^{2}+5x+6\)

A rectangular floor with a length of 14 ft and a width of 6 ft, square tiles with an edge length of 3/4 ft, a total of 144 tiles can fit.

To determine how many square tiles can fit in a rectangular floor, we need to calculate the total number of tiles that can fit both horizontally and vertically.

Given:

Length of the rectangular floor = 14 ft

Width of the rectangular floor = 6 ft

Edge length of square tile = 3/4 ft

First, let's calculate the number of tiles that can fit horizontally:

Length of the rectangular floor / Edge length of square tile = 14 ft / (3/4 ft) = 14 ft × (4/3 ft) = 56/3 ft

Since we want a whole number of tiles, we need to round down or take the floor value:

Number of tiles horizontally = floor(56/3) = 18 tiles

Next, let's calculate the number of tiles that can fit vertically:

Width of the rectangular floor / Edge length of square tile = 6 ft / (3/4 ft) = 6 ft × (4/3 ft) = 24/3 ft

Again, we round down or take the floor value:

Number of tiles vertically = floor(24/3) = 8 tiles

To find the total number of tiles, we multiply the number of tiles horizontally by the number of tiles vertically:

Total number of tiles = Number of tiles horizontally × Number of tiles vertically = 18 tiles × 8 tiles = 144 tiles

Therefore, in a rectangular floor with a length of 14 ft and a width of 6 ft, square tiles with an edge length of 3/4 ft, a total of 144 tiles can fit.

Random points can be generated on a two-dimensional plane by using a random number generator to produce two sets of numbers, one for each coordinate.

Two-dimensional (2D) is a term used to describe objects that have only two dimensions, such as length and width, and no depth or thickness. Common examples of two-dimensional objects include flat surfaces like paper, photographs, and posters, as well as shapes such as circles, squares, and triangles. In contrast, three-dimensional objects have length, width, and depth.

For example, if the range of the random numbers is between 0 and 10, then a random point on the plane could be (3.5, 7.2). This point would be located 3.5 units to the right on the x-axis and 7.2 units up on the y-axis.

Answer:

0.000004 = 0.0004% probability of getting 7 or fewer minorities if the jury pool was randomly selected.

Step-by-step explanation:

For each person, there are only two possible outcomes. Either it was a minority, or it was not. The probability of a person being a minority is independent of any other person. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

And p is the probability of X happening.

Jury of 90 people:

This means that \(n = 90\)

27% were minorities.

This means that \(p = 0.27\)

Find the probability of getting 7 or fewer minorities if the jury pool was randomly selected.

This is:

\(P(X \leq 7) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6) + P(X = 7)\)

In which

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 0) = C_{90,0}.(0.27)^{0}.(0.73)^{90} \approx 0\)

\(P(X = 1) = C_{90,1}.(0.27)^{1}.(0.73)^{89} \approx 0\)

\(P(X = 2) = C_{90,2}.(0.27)^{2}.(0.73)^{88} \approx 0\)

\(P(X = 3) = C_{90,3}.(0.27)^{3}.(0.73)^{87} \approx 0\)

\(P(X = 4) = C_{90,4}.(0.27)^{4}.(0.73)^{86} \approx 0\)

\(P(X = 5) = C_{90,5}.(0.27)^{5}.(0.73)^{85} \approx 0\)

\(P(X = 6) = C_{90,6}.(0.27)^{6}.(0.73)^{84} \approx 0\)

\(P(X = 7) = C_{90,7}.(0.27)^{7}.(0.73)^{83} = 0.000004\)

So

\(P(X \leq 7) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6) + P(X = 7) = 7*0 + 0.000004\)

0.000004 = 0.0004% probability of getting 7 or fewer minorities if the jury pool was randomly selected.

The expected total dollar net operating Income for next year = $70,000

1) The contribution format income statement for the game last year, and the degree of operating leverage is computed below:

Contribution format income statement for the game last year Sales (15,000 × $20) = $300,000

Variable expenses (15,000 × $6) = $90,000

Contribution margin = $210,000

Fixed expenses = $182,000Net operating income = $28,000

Degree of operating leverage = Contribution margin / Net operating income= $210,000 / $28,000= 7.5 2)

The expected percentage increase in net operating income for next year:

The expected sales in next year = 18,000

games selling price per game = $20

Therefore, Total sales revenue = 18,000 × $20 = $360,000

Variable expenses = 18,000 × $6 = $108,000

Fixed expenses = $182,000

Expected net operating income = Total sales revenue – Variable expenses – Fixed expenses

= $360,000 – $108,000 – $182,000= $70,000

The expected percentage increase in net operating income = (Expected net operating income - Last year's net operating income) / Last year's net operating income*100= ($70,000 - $28,000) / $28,000*100= 150%

The slope of 0.75 corresponds to option 3. So, the correct answer is 3) 0.75.

To find the slope, we can use the formula for the slope of a line:

slope (m) = (change in y) / (change in x)

In this case, x represents the number of miles to the destination and y represents the total cost of the load.

Given that the charge to deliver a load 40 miles is $280 and the charge to deliver a load 56 miles is $292, we can set up two points on the line: (40, 280) and (56, 292).

Now let's calculate the change in y and change in x:

Change in y = 292 - 280 = 12

Change in x = 56 - 40 = 16

Plugging these values into the slope formula:

slope (m) = (change in y) / (change in x) = 12 / 16 = 0.75

Therefore, the slope of the line representing the relationship between the number of miles (x) and the total cost of the load (y) is 0.75.

Option 3 is correct.
