Manufacturing overhead costs typically include the depreciation of equipment, wages provided to factory personnel, and power used to operate the equipment. $10.8 million, $8.4 million, and $17.4 million will make up the three divisions.

Manufacturing overhead (MOH) cost is the sum of all indirect costs incurred during the production of a good.

It is included in the cost of the final good along with the costs of direct materials and direct labor.

In the manufacturing sector, the three major cost components are materials, labor, and overhead. There are no hidden expenses.

In other words, while the foreman's pay and supplies are covered, neither the office's nor the corporation's accountant's pay is. To calculate applicable production overhead, multiply the overhead allocation rate by the amount of labor or equipment used. Therefore, if your allocation rate is $25, your applied manufacturing overhead for this product is $25.

According to the second derivative test, whether or not there is a relative maximum or minimum at a crucial number depends on the sign of the second derivative. According to the second derivative test, in this situation, -2 and 0 result in a relative minimum, whereas 2 results in a relative maximum.

To ascertain if a crucial number belongs to a relative maximum or relative minimum, one can utilise the second derivative test. Calculate the function's second derivative before using the test. After that, calculate the second derivative at the threshold value. The critical number relates to a relative maximum if the second derivative is negative. The crucial number corresponds to a relative minimum if the second derivative is positive. Specifically, At -2 and 0, when the second derivative is negative, there is a relative minimum. The crucial number 2 corresponds to a relative maximum since the second derivative is positive at that value.

Answer: 20

Step-by-step explanation: Hello! The first thing you have to do is substitute m = 7 and n = 5 into the equation 4 + (m - n)^4.  After substituting m and n into the equation, you will get: 4 + (7 - 5)^4.  Use PEMDAS (parentheses, exponents, multiplication, division, addition, and subtraction).  Parentheses is first, so solve everything inside of the parentheses first.  7 - 5 = 2.  Now you have 4 + (2)^4.  Next is exponents in pemdas, so solve the exponents.  2^4 = 2 x 2 x 2 x 2, or 4 x 4, or 16.  Now you have 4 + 16.  The last thing you have to do is add 4 + 16, which is 20.  The answer is 20.

Using slope intercept equation the value of p is -2.4 .

What is slope intercept equation?

When the slope of the line being studied is known, and the provided point is also the y intercept, the slope intercept formula, y = mx + b, is utilised (0, b).   It provides both a slope and an intercept, which is why the form is known as the slope-intercept form.

Let’s call line m y’ and we can deduce that y’ = ax where a is the slope of line y’. (In the standard line equation, y = mx + b, b is the y intercept which, in the case of line m, is zero since it passes through the origin (0,0).)

Then name the 2nd line y’’ = -6x + h

When straight lines are perpendicular, their slopes are negative inverses. So the slope of line y’, which I’ve called a, must equal +1/6

Now we know that y’ = (1/6)x and y’’ = -6x + h

If the lines intersect at a point (x , y) which we are told is (p, p+2), then at that point y’ = y’’, or p+2 = (1/6) and p = -6(p+2) + h.

From this we can solve for p,

=> p - p/6 = -2=> (5/6)p = -2 or

=>p = -12/5 = -2.4

Now we know that the intersection point (p,p+2) is (-2.4, -0.4)

Hence the value of p is -2.4 .

Answer:

y = 1/4x

Step-by-step explanation:

A proportional relationship is similar to a linear relationship, with one distinction, it's y-intercept is equal to zero, so it can be expressed in the form: [tex]y=kx[/tex], where "k" is some constant. More specifically, when we divide y by x, we always get a constant amount, denoted as "k": [tex]\frac{y}{x}=k[/tex].

Using this knowledge, we can kind of immediately tell it's [tex]y=\frac{1}{4}x[/tex] as it's the only one in the form: [tex]y=kx[/tex], but let's look at why [tex]x=\frac{3}{8}[/tex] is not a proportional relationship.

It's important to note that [tex]x=\frac{3}{8}[/tex] is a vertical line, since the x value is constant while the y value varies. This means "y/x" cannot be constant, since "y" changes, except what it's being divided by will remain the same, equal to 3/8.

In year 2015 the sum of the age of maria, her mother, and her father, will be 100 years.

As the date and month of the birth is same for maria, her mother, and her father. Lets say in year X, the sum of the age will be 100 years.

The age of maria in year X = (X - 2000)

The age of her mother in year X, = (X - 1975)

The age of her father in year X, = (X - 1970)

Sum of their age,

100 = (X - 2000) + (X - 1975) + (X - 1970)

100 = 3X - (2000 + 1975 + 1970)

100 = 3X - 5945

The three triangle theorems include the following:

The positions of the theorems are as follows:

The Pythagorean Theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides (the legs) is equal to the square of the length of the longest side (the hypotenuse). This can be written as a^2 + b^2 = c^2, where c is the length of the hypotenuse and a and b are the lengths of the legs.

The Law of Cosines states that in any triangle, the square of the length of a side is equal to the sum of the squares of the lengths of the other two sides, minus twice the product of the length of one side times the cosine of the angle between the other two sides. This can be written as c^2 = a^2 + b^2 - 2ab * cos(C)

The Law of Sines states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle. This can be written as a/sin(A) = b/sin(B) = c/sin(C)

In reference to different sampling methods, systematic sampling includes the steps: divide the population into groups; use simple random sampling to identify a proportionate number of individuals from each group: [FALSE]

Systematic sampling is a method of sampling where the sample is selected using a fixed interval, rather than using random sampling. The sampling process begins by selecting a random starting point in the population and then selecting every kth element from the population.

For example, if the population has 100 elements and k=10, every 10th element would be selected for the sample.

Dividing the population into groups, and then using simple random sampling to identify a proportionate number of individuals from each group is a method called stratified sampling.

It is important to note that systematic sampling can be vulnerable to sampling bias if the sampling interval is not chosen carefully and the population is not randomly ordered, because in that case, it will not be a truly random sample.

Every vertex of a graph can be assigned an integer in {1, 2, ..., d1} so that no two adjacent vertices are assigned the same integer.

We can use induction to show that every vertex of a graph can be assigned an integer in {1, 2, ..., d1} so that no two adjacent vertices are assigned the same integer. Let G be a graph with d vertices, and assume that the result is true for all graphs with fewer than d vertices. Consider any vertex v in G and let N(v) be the set of neighbours of v. Since |N(v)| < d, by our induction hypothesis, there is an assignment of the integers 1,2, ..., d−1 to the vertices in N(v) so that no two adjacent vertices are assigned the same integer. Now assign the dth integer, i.e., d, to v and we are done. By our induction hypothesis, this assignment works for all graphs with d vertices.

The black point (plus symbol) selected on the graph has coordinates of (4, 0.4).

This point represents the intersection of the two curves on the graph. To calculate the quantity of boxes represented by this point, we can use the equation y=mx+b, where m is the slope of the line, x is the x-coordinate, and b is the y-intercept.

In this case, the slope of the line is -2, the x-coordinate is 4, and the y-intercept is 0.4. We can substitute these values into the equation to solve for the quantity of boxes, which would be: y=-2x+0.4. Plugging in the x-coordinate of 4, we would get: 0.4=-2(4)+0.4, which simplifies to 0.4=-8. Solving for y, we would get 8 boxes. Therefore, the point (4, 0.4) on the graph represents a quantity of 8 boxes.
