How equations are formed?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left-hand side = right-hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it has no "equal to" sign. It will be regarded as a phrase.

It is Given:

each child needs 222 forks

each adult needs  555 forks

total number of forks = 299229922992

total number of people = 764764764

Let the number of children be c

and Let the number of adults be a

According to the question:

c + a = 764764764

222c + 555a = 299229922992

find the value of c using the 1st equation.

c = 764764764 - a

substitute c in the 2nd equation by its value

222c + 555a = 2992

222(764764764-a) + 555a = 299229922992

169777777608 - 222a + 555a = 299229922992

333a =299229922992 - 169777777608

333a = 129452145384

a = 388745181

c = 764764764 - 388745181

c = 376019583

Hence, The number of children is = 376019583;

The number of adults is = 388745181

So, the description that matches the given expression is "difference of thirteen and the quotient of five and a number".

Therefore, the correct option is C.

Answer:

the difference of thirteen and the quotient of five and a number

Step-by-step explanation:

The position of the mass in the undamped spring-mass system can be represented by the equation u(t) = (A cos(ωt) + B sin(ωt)) / k. Therefore, position of the mass at any time t in feet is given by u(t) = 4.5 cos(4t).

In this case, the external force acting on the system is 108 cos(4t) lb. To determine the position of the mass, we need to solve the differential equation that represents the motion of the system.

Using Newton's second law, F = ma, and considering that the mass m = 24 lb, the equation becomes:

24 * d^2u/dt^2 = 108 cos(4t)

Simplifying, we have:

d^2u/dt^2 = 4.5 cos(4t)

This is a second-order linear homogeneous differential equation with a constant coefficient. The solution to this equation will be a linear combination of the homogeneous and particular solutions.

The homogeneous solution, representing the free oscillation of the system, is u_h(t) = C1 cos(2t) + C2 sin(2t).

The particular solution, representing the forced motion caused by the external force, can be assumed in the form u_p(t) = A cos(4t) + B sin(4t).

By substituting u_p(t) into the differential equation, we can determine the values of A and B.

Solving the differential equation for the particular solution, we find:

A = 18 and B = 0

The complete solution for the position of the mass in feet is:

u(t) = (18 cos(4t)) / 4

Simplifying further, we get:

u(t) = 4.5 cos(4t)

Therefore, the position of the mass at any time t in feet is given by u(t) = 4.5 cos(4t).

Answer:

The correct option is;

Shirt Express charges less per shirt. For the cost to be the same 74 shirts must be ordered

Step-by-step explanation:

1) The given table for Shirt Express can be used to find the equation of the total cost of each made by Shirt Express as follows;

The rate of change of the function m is given as follows;

\(m = \dfrac{y_2 - y_1 }{x_2 - x_1}\)

Therefore, we have;

m = (438 - 353)/(50 - 40) = 8.5

Te equation in slope and intercept form is then y - 438 = 8.5(x - 50)

From which we have;

y = 8.5·x - 8.5×50 + 438 = 8.5·x + 13

y = 8.5·x + 13

Therefore, Shirt Express initially charges 13 per shirt which is less than the 50 Shirt Custom charges

2)  the cost to be the same, we equate both shirts equations to get;

8.5·x + 13 = 8·x + 50

0.5·x = 50 - 13 = 37

x = 37/0.5 = 74 shirts

Therefore, for the cost to be the same 78 shirts must be ordered

This formula gives the total number of ways to assign m jobs to n employees so that each employee is assigned at least one job.

What is combinatorics?

Combinatorics is a branch of mathematics that deals with counting and arranging the possible outcomes of different arrangements and selections of objects. It is concerned with the study of discrete structures, such as graphs, hypergraphs, and matroids, and their properties.

This problem is a classic example of applying the principle of inclusion-exclusion.

Let's start by assuming that we can assign any number of jobs to each employee, without the constraint that each employee must receive at least one job. In this case, the number of ways to assign m jobs to n employees would be n^m, since each job has n choices of employee to assign it to.

However, we need to subtract the number of cases where at least one employee is left without a job. This can happen in m different ways, since we can choose any of the m jobs to be unassigned. For each of these cases, there are \((n-1)^{m}\) ways to assign the remaining jobs to the n-1 remaining employees.

However, we have now "overcorrected" for cases where more than one employee is left without a job, since we have subtracted those cases twice (once for each pair of employees that are left out). To correct for this, we need to add back in the number of cases where at least two employees are left without a job. This can happen in (m choose 2) ways, since we can choose any pair of jobs to be unassigned. For each of these cases, there are \((n-1)^{m}\) ways to assign the remaining jobs to the remaining n-2 employees.

We continue this process of alternating subtraction and addition for all possible numbers of employees left without a job, up to n-1. The final answer is:

\(n^{m}\) - \((n-1)^{m}\) * m + \((n-2)^{m}\) * (m choose 2) - \((n-1)^{m}\) * (m choose 3) + ... + \((-1)^{(n-1)}\) * \(1^{m}\) * (m choose n-1)

This formula gives the total number of ways to assign m jobs to n employees so that each employee is assigned at least one job.

Step-by-step explanation:

Answer:

y-intercept: (0,6)

slope = -2

equation: y = -2x + 6  

Step-by-step explanation:

1) First, identify the y-intercept. The y-intercept is the point at which the line intersects the y-axis. We can see that the line crosses the y-axis at (0,6), so that must be it.

2) Now, find the slope. Pick two points from the line. I chose (0,6) and (3,0). Then, substitute the two points' x and y values into the slope formula \(m = \frac{y_2-y_1}{x_2-x_1}\)and solve:

\(m = \frac{0-6}{3-0}\\m = \frac{-6}{3}\\m = -2\)

So, the slope is -2.

3) With the found information, use the slope-intercept formula \(y = mx + b\) to write the line's equation. Substitute values for the \(m\) and \(b\).

\(m\) represents the slope, so substitute -2 in its place. \(b\) represents the y-intercept, so substitute 6 in its place. This gives the following equation:

\(y = -2x + 6\)

The solution to the given LP problem using the simplex method is: x1 = 2, x2 = 0, z = 8

The probability of obtaining a sum of 10 is 7/216, which is the

To find the probability of the sum of the numbers showing face up being 10, we need to count the number of ways in which we can obtain a sum of 10 when throwing three six-sided dice.

We can approach this problem by using combinations. For example, if we roll a 4, a 3, and a 3, we obtain a sum of 10. However, if we roll a 5, a 4, and a 1, the sum is also 10, but the order of the dice is different. Since the order of the dice does not matter, we can use combinations to count the number of ways to obtain a sum of 10.

We can start by considering the number of ways to roll a 10 with two dice. This can be done using a table, where the rows and columns represent the numbers on the two dice, and the entries represent the sum of the two numbers. For example:

From the table, we can see that there are four ways to roll a 10 with two dice: (4,6), (5,5), (6,4), and (3,7).

To count the number of ways to roll a 10 with three dice, we need to consider all possible combinations of the numbers that add up to 10. We can use the fact that the order of the dice does not matter, so we can write each combination in increasing order. For example, (1,3,6) and (3,1,6) are equivalent, and we only need to count one of them.

Using this method, we can write all possible combinations of three dice that add up to 10:

(1,2,7)

(1,3,6)

(1,4,5)

(2,2,6)

(2,3,5)

(2,4,4)

(3,3,4)

There are seven possible combinations, so the probability of obtaining a sum of 10 with three dice is 7 divided by the total number of possible outcomes when rolling three dice, which is 6^3 = 216.

Therefore, the probability of obtaining a sum of 10 is 7/216, which is the final answer.

The point estimate of the difference in the population mean exercised between underclassmen and upperclassmen is 0.16 hours.

In this case, we are estimating the difference in population means between two groups - upperclassmen and underclassmen. The point estimate is calculated by subtracting the sample mean of the underclassmen from the sample mean of the upperclassmen, which gives us

0.76 - 0.60 = 0.16.
the point estimate of the difference in population mean exercised between underclassmen and upperclassmen is 0.16 hours, which was calculated by subtracting the sample mean of underclassmen from the sample mean of upperclassmen.
Point Estimate = (Sample Mean of Upperclassmen) - (Sample Mean of Underclassmen)
Point Estimate = (0.76) - (0.60)
Point Estimate = 0.16

Hence, the point estimate of 0.16 suggests that, on average, upperclassmen exercised 0.16 hours more than underclassmen in the past 24 hours. This is a rough estimate of the difference between the two population means based on the provided sample data.

But without control over variables that could affect the second scores, there is there is hardly a strong argument for the reliability of her test. Moreover, some of the couples may not be together after a year has passed.

Falsifiability or refutability is the probability that a statement can be falsified or proven false through observation or physical testing. Something that can be falsified does not mean that it is wrong, but it means that if the statement is wrong, then the error can be shown.

The claim that "it is not true that humans live forever" cannot be falsified because it is impossible to prove wrong. In theory, one would have to observe a human living forever to falsify that claim. On the other hand, "all humans live forever" is falsifiable because the death of a single human being can disprove the statement false (excluding metaphysical statements about the soul, which cannot be falsified).

Falsifiability, especially testability, is an important notion in science and philosophy of science. This thought was popularized by Karl Popper. Popper stated that a hypothesis, proposition, or theory is scientific if it can be falsified. Falsifiability is an important (but not sufficient) criterion for scientific ideas. He also stated that statements that cannot be falsified are unscientific.

If the probability of having a defect is 20%, then the probability that there is no defect is 0.8 or 80%.

The probability that there is no defect can be calculated by subtracting the probability of having a defect from 1. Since the probability of having a defect is 20%, the probability of no defect is:

1 - 0.20 = 0.80

Therefore, the probability that there is no defect is 80%.

In probability theory, the complement rule states that the probability of an event occurring is equal to 1 minus the probability of its complement. In this case, the event of interest is having no defect, and its complement is having a defect.

If the probability of having a defect is 20%, it means that out of every 100 cases, 20 cases would have a defect. Hence, the remaining 80 cases would not have a defect. This means that the probability of no defect is 80% or 0.80.

By subtracting the probability of having a defect (20%) from 1, we obtain the probability of no defect (80%). This is because the sum of the probabilities of mutually exclusive events must be equal to 1. Therefore, the probability that there is no defect is 80%.
