What is the inventory about?

Denoting the valuation of inventories a business owns at the completion of any accounting term – be it monthly, quarterly, or annually – ending inventory speaks to the cost of items that have yet to be sold or used in the creation of goods and services.

Checking a company's economic performance is contingent on examining its ending inventory since this element impacts cost of goods sold (COGS) substantially; many corporations' COGS are worked out by subtracting the cost of goods distributed over a period from the overall cost of goods available for sale during that same interval.

The cost that a recycling company charges is directly proportional to the number of recycling bins collected. The cost is $33 for each bin.

A: Write a direct variation equation to represent the cost.
B: How many bins can a customer pay the company to collect the bins for $500? Write and solve the equation.
C: Suppose the customer plans to tip the recycling company $30, how many bins can the customer get removed for $500 now? Write and solve the equation.

Answers

a) The direct variation equation is y = 33x.

b) The customer can pay the company to collect 15 bins.

c) The customer can get approximately 16 bins (rounded to the nearest whole number) removed for $500 with a $30 tip included.

A) The direct variation equation to represent the cost would be y = kx, where y represents the cost, x represents the number of bins collected, and k is the constant of proportionality. In this case, since the cost is $33 for each bin collected, the value of k is 33. Therefore, the direct variation equation is y = 33x.

B) To find the number of bins a customer can pay the company to collect for $500, we can set the cost (y) equal to $500 and solve for x (the number of bins). Thus, we have:

y = 33x

500 = 33x

x = 500/33

x ≈ 15.15

Therefore, the customer can pay the company to collect 15 bins (rounded to the nearest whole number) for $500.

C) If the customer plans to tip the recycling company $30, the total cost would be $500 + $30 = $530. We can set the cost (y) equal to $530 and solve for x:

y = 33x + 30

530 = 33x + 30

500 = 33x

x ≈ 15.91

Answers

A function with a vertex must switch from increasing to decreasing or vice versa at the vertex. So, the function cannot be only increasing or only decreasing over its entire domain.

Given data ,

A function with a vertex, also known as a vertex form of a quadratic function, is a function of the form f(x) = a(x-h)^2 + k, where (h, k) represents the vertex of the parabola. The vertex is the point on the parabola where it changes direction from increasing to decreasing or vice versa.

It is impossible for a function with a vertex to increase continuously if its whole domain shows an increase in the function. Similar to the last example, a function with a vertex cannot decrease throughout its whole domain because that would imply that the function is constantly decreasing.

Hence , a function with a vertex must switch from increasing to decreasing or vice versa at the vertex, and it cannot be only increasing or only decreasing over its entire domain.

Step 2 : x 2 + 4 x + 4 = 81
Step 3 : ( x + 2 ) 2 = 81
Step 4 : x + 2 = ± 81
Step 5 : x = 79 , x = − 83

Answers

The error made by Tony is in Step 4, where he wrote "x + 2 = ± 81". The correct step should be:

Step 4: Take the square root of both sides to solve for x.

√((x + 2)^2) = √81

In this step, Tony should have taken the square root of both sides, but he made the mistake of only taking the square root of the right-hand side and neglected to take the square root of the left-hand side correctly.

The correct step should be:

x + 2 = ±9

Step 5: Solve for x.

x + 2 = 9 or x + 2 = -9

Step 6: Subtract 2 from both sides to isolate x.

x = 9 - 2 or x = -9 - 2

This will give the correct solutions:

x = 7 or x = -11

So, the error made by Tony occurred in Step 4 where he only took the square root of the right-hand side and neglected to take the square root of the left-hand side correctly.

Answers

the probability of a major tornado in three consecutive years is 1/8000.   the probability of not having a major tornado in the next ten years is approximately 0.328. he probability of having at least one major tornado in the next ten years is approximately 0.672.

How to the probabilities in the question

(a) The probability of a major tornado in any single year is 1/20. To find the probability of a major tornado in three consecutive years, we multiply the probabilities together:

P(major tornado in 3 consecutive years) = (1/20) * (1/20) * (1/20) = 1/8000

So the probability of a major tornado in three consecutive years is 1/8000.

(b) The probability of not having a major tornado in any single year is 19/20. To find the probability of not having a major tornado in the next ten years, we raise this probability to the power of 10:

P(no major tornado in next 10 years) = (19/20)^10 ≈ 0.328

So the probability of not having a major tornado in the next ten years is approximately 0.328.

(c) To find the probability of having at least one major tornado in the next ten years, we can subtract the probability of having no major tornadoes in the next ten years from 1:

P(at least one major tornado in next 10 years) = 1 - P(no major tornado in next 10 years)

P(at least one major tornado in next 10 years) = 1 - (19/20)^10 ≈ 0.672

So the probability of having at least one major tornado in the next ten years is approximately 0.672.

Define term positive integer number?

A positive integer is a whole number greater than zero, i.e., any number that can be expressed without fractions or decimals, and is greater than zero.

If the difference of two numbers is less than the sum of the numbers, it is always true that at least one of the numbers is positive. As a result, "At least one of the numbers is positive" is the response, which is (G).

Here we assume that x and y are two numbers. The difference between the two numbers is |x - y|, which is always positive.

Now, according to the given condition:

|x - y| < x + y

Simplifying this inequality, we get:

-x + y < x + y

2y > 0

Dividing both sides by 2, we get:

y > 0

Therefore, we can conclude that at least one of the numbers (y) is positive. Note that it is possible for both numbers to be positive or for one number to be positive and the other to be zero.

B. 7 = (1/2)x+ 0

C. y= (1/2)x+ 7

Answers

The answer is C

Explanation:

The slope-intercept form of a line is given by y = mx + b, where m is the slope of the line and b is the y-intercept.

In this case, we are given that the slope of the line is 1/2, and the y-intercept is the point (0, 7). Therefore, we can substitute these values into the slope-intercept form to get:

y = (1/2)x + 7

So, the equation of the line in slope-intercept form is y = (1/2)x + 7.

The sum of two numbers exceeds a third number by four. If the sum of the three numbers is at least 20 and 28,find any three intgral values satisfying the inequality .

Answers

Answer:

Let the three numbers be x, y, and z.

We are given that x + y = z + 4.

We are also given that x + y + z >= 20 and x + y + z <= 28.

Combining these two inequalities, we get:

z + 4 + z >= 20

2z >= 16

z >= 8

Since z is an integer, z can be 8, 9, 10, 11, 12, 13, 14, 15, 16, or 17.

For each value of z, we can find the corresponding values of x and y using the equation x + y = z + 4.

For example, if z = 8, then x + y = 12.

So, the three integral values satisfying the inequality are 8, 4, and 0.

Another example is z = 15.

In this case, x + y = 19.

So, the three integral values satisfying the inequality are 15, 2, and 2.

Answers

the total number of students in the group is (5/17)12B. We don't have a specific value for B, so we can't give a specific answer for the number of students,

How to solve the problem?

Let's use the following variables to represent the unknowns in the problem:

Let A be the area of area A

Let B be the area of area B

Let x be the number of students working in area B in the morning

Let 3x be the number of students working in area A in the morning

Let y be the total number of students in the group

From the problem statement, we know that A = 1.5B (since area A is 1.5 times area B). We also know that in the morning, the number of students working in area A is 3 times the number of students working in area B. This can be expressed as:

3x = y/2 (since half of the students work in the morning)

In the afternoon, 7/12 of the students work in area A, so the number of students working in area B is:

(1-7/12)y = 5/12y

At the end of the day, area A is done and area B still needs 4 more students to work for another day. This means that the amount of work done by the students in area B is (y/2 - 3x) + (5/12y - 4B) = B, since the total work needed to be done in area B is B and the amount of work done by the students in area A is y/2 - 3x.

Substituting A = 1.5B and 3x = y/2, we can solve for y:

(y/2 - 3x) + (5/12y - 4B) = B

y/2 - 3(y/2)/3 + 5/12y - 4B = B

y/2 - y/2 + 5/12y = 5B

17/12y = 5B

y = (5/17)12B

Therefore, the total number of students in the group is (5/17)12B. We don't have a specific value for B, so we can't give a specific answer for the number of students, but we can say that the number of students is proportional to the area of area B. If we know the area of area B, we can use the equation above to find the total number of students in the group.

An expression in factored form for the polynomial of least possible degree is y(x) = (x-2)(x+2).

What is polynomial?

Polynomials can be represented in various forms, including standard form, factored form, and expanded form. Standard form is where the polynomial is written with the terms in descending order of degree, with coefficients in front of each term. Factored form is where the polynomial is written as a product of linear factors, and expanded form is where the polynomial is written out in full, with all the terms multiplied together.

A polynomial is a mathematical expression consisting of variables and coefficients, which are combined using addition, subtraction, and multiplication operations. The variables are raised to non-negative integer powers, and the highest power of the variable is called the degree of the polynomial.

For example, the polynomial 2x³ + 3x³ - 4x + 1 has degree 3, as the highest power of x is 3. The coefficients in this polynomial are 2, 3, -4, and 1.

Here, the curve touch two points (-2,0) and (2,0).

So, we can say (-2) and 2 are the root of the polynomial.

Since there is no graph or equation I can only tell you Tom and Philip need to use rise over run to find slope on a graph.

If they have points on the graph or points on a table, they can use slope formula

y2 - y1 over x2 - x1

matrix A = 2 -7 matrix B = -9 5
6 1 1 -1

If X - A = B, what is X?

Answers

To find X, we need to add A to both sides of the equation X - A = B:

X - A + A = B + A

Simplifying the left side, we get:

X = B + A

To add two matrices, we add their corresponding elements. Thus:

X = [-9+2, 5-7; 6+1, 1-1]

X = [-7, -2; 7, 0]

Therefore, X is the matrix [-7, -2; 7, 0].

Draw a bar chart to show how the price increased​

What is a bar chart?

A bar chart, sometimes known as a bar graph, is a type of chart or graph that displays categorical data using rectangular bars with heights or lengths proportionate to the values they represent. The bars can be plotted horizontally or vertically. A vertical bar chart is also known as a column chart.

From the bar chart, is clarer to see that the price of ground nut per tone increased steadily year on year.

By the year 2008, it had hit  record high of 100,000 per ton.

I am confused on how to solve the table and find the velocity

Answers

Answer:

Step-by-step explanation:

y = 5x^3 - x

Slope of a secant

= (y2 - y1)/(x2-x1)     where (x1, y1) and (x2, y2) are the 2 points.

Slope for the interval (1, 2)

= [5(2)^3 - 2)- (5(1)^3 - 1)] / (2-1)

= 34

Slope for interval (1, 1.5)

=  [5(1.5)^3 - 1.5)- (5(1)^3 - 1)] / (1.5-1)

= 22.75

In the same way we get the slopes of the  intervals:

(1, 1.1):-  15.55

(1, 1,01):-  15.15

(1, 1.001):- 15.015

So the answer is 15.

Malpractice Case Study: There are no absolute answers with some of questions they are mean to stimulate discussion and examination of complex issues.Madison Wills worked night shift on a neonatal intensive care unit (NICU) at a major medical center. She assumed the care of a very sick premature infant that weighed 1 kilogram (a little over 2 pounds). Sylvia Smithson had been the infant's nurse during the day shift. Sylvia had initiated the infant's intravenous (IV) antibiotic infusion at 6:30 p.m., just before shift change. She reported that the infant's IV line in his arm was patent and the IV site had no redness or swelling.When Madison assessed the infant at 7:45 after the end-of-shift report, she noted that the baby's arm was swollen and that the IV had infiltrated (was no longer in the vein). When she stopped the infusion, she also noted that the dose on the antibiotics was incorrect and was much too large for a very small infant.What is the first thing that Madison should do after discovering these two problems?Which of these problems (the infiltration or the dosing) was the most significant?What is the nurse's responsibility when an antibiotic is prepared by the pharmacy?What safeguards are in place to protect nurses from charges of negligence?
