A manufacturer has determined that the combined fixed and variable expenses for the production and sale of 500,000 items are $10,000,000. What is the price at the breakeven point for this item?
Answers
The breakeven point is the point at which a company's revenue is equal to its costs. In this case, the combined fixed and variable expenses for the production and sale of 500,000 items are $10,000,000, so the breakeven point for this item would be $10,000,000 / 500,000 items = $100000000/500000=$20 per item.
To determine the price at the breakeven point, we need to know the total revenue that the company is aiming to achieve. If the company's goal is to sell the items at a price above the breakeven point in order to make a profit, then the price at the breakeven point would be $20 per item.
However, if the company is simply trying to recover its costs, then the price at the breakeven point would be the same as the breakeven point, or $20 per item.

What is an example of a linear function table?.
Answers
An example of a linear function table is y=3x
A linear function is used to relate an independent variable and a dependent variable by introducing a rate of change(function) of which the independent variable is equated to find the dependent variable. Linear functions are those whose graph is a straight line. The following is the form of a linear function. a + bx = y = f(x). One independent variable and one dependent variable make up a linear function. X and Y are the independent and dependent variables, respectively.
for example:
y=3x hence is the dependent variable as it depends on the change of x and 3 is the rate of change which is a constant and is determined by the division of the values of y/x hence to make a table of y over x of which y is determined by the rate of change the unrelated variable x, 3.

saul plans to complete more than 225 hours of volunteer work during a 9-month period. he has already completed 36 hours of volunteer work. which inequality describes all the additional numbers, h, of hours of volunteer work that saul could complete each month to meet his goal?
Answers
The inequality that satisfies the number of hours of volunteer work that saul could complete each month to meet his goal is 21 hours.
An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.
Different types of inequalities are represented by a variety of notations, including:
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that an is bigger than b.
Given,
Hours Saul plans to volunteer in the 9-month period = 225 hours
Also,
Hours of volunteering he has already completed = 36 hours
=> Number of hours left = 225 - 36 =189 hours
Number of months= 9
=> Minimum number of hours he has to volunteer per month
=> \(\frac{Number of hours left}{Number of months}\)
=>\(\frac{189}{9}\\ 21 hours\)
=>Minimum number of hours saul has to volunteer per month ≥ 21 hours
Therefore, The number of hours of volunteer work that saul could complete each month to meet his goal is 21 hours.

solve the following 19+n=30
Answers
Answer:

Step-by-step explanation:
19+n=30
n=30-19
n=11
Answer:
n=11
Step-by-step explanation:
In order to solve this equation, we need to find out what n is. We have to get n by itself on one side of the equation. Perform the inverse operations to both sides of the equation.
19+n=30
19 is being added to n. The inverse of addition is subtraction. Subtract 19 from both sides.
19-19+n=30-19
n=30-19
n=11
Let's check out solution. Plug 11 in for n in the original equation.
19+n=30
19+11=30
30=30

a Carlo and Anita make mailboxes and toys in their craft shop near Lincoln. Each mailbox requires 3 hours of work from Carlo and 4 hours from 3 hours of work from Carlo and 2 hours from Anita. Carlo cannot work more than 18 hours per week and Anita cannot work more than 16 hours per week. If each mailbox sells for $9 and each toy sells for $17, then how many of each should they make to maximize their revenue? What is their maximum revenue? GLITES Carlo and Anita should make mailboxes and toys. Their maximum revenue is $.
Answers
To maximize their revenue, Carlo and Anita should determine the optimal quantities of mailboxes and toys to produce. Let's denote the number of mailboxes as x and the number of toys as y.
Given that each mailbox requires 3 hours of work from Carlo and 2 hours from Anita, and each toy requires 4 hours from Carlo and 3 hours from Anita, we need to consider their weekly working hour limitations. Carlo cannot work more than 18 hours per week, so 3x + 4y ≤ 18. Anita cannot work more than 16 hours per week, so 2x + 3y ≤ 16.
The objective is to maximize revenue, which is given by the equation R = 9x + 17y, where R represents revenue.
To find the optimal solution, we can use linear programming techniques such as graphical analysis or the simplex method. By solving the system of inequalities and evaluating the revenue function at the feasible points, we can determine the maximum revenue and the corresponding quantities of mailboxes and toys.
Unfortunately, the information provided in the question is insufficient to determine the exact solution and maximum revenue. The specific values of x and y that maximize revenue need to be calculated or approximated using additional constraints or information.

the correlation between variables x and y is .50. You compute a least squares regression line wit this bivariata data. Which of the following is true?
a. the r^2 is greater than .50
b. the regression constant is positive
c. the regression coefficient is positive
d. the slope of the regression line is negative
e. all of the above
Answers
The correlation between variables x and y is 0.50 . The true option is option (c) .
that's the regression coefficient is positive for given bivariata.
Correlation: Correlation is a statistical measure of how linearly two variables are related (meaning they change together at a constant rate). The
sample correlation coefficient r quantifies the strength of the relationship.
Correlation Coefficient: The Correlation Coefficient formula is used to examine the strength of the relationship between data. The formula returns a value between -1 and 1.
Here:
1 indicates a strong positive relationship.-1 indicates a strong negative relationship.A result of zero indicates no relationship at allPearson's correlation coefficient is denoted by "r" and is
r = (n∑xy - ∑x∑y )/√( n ∑x² - (∑x )² ) ( √ n∑y² - (∑y)²)
We have given that correlation between x and y is 0.50.
cor(x,y) = √r^2 => √r^2 = 0.50 => r ^2 = (0.50)^2
=> r^2 = 0.25 > 0 but less than 0.50 ---( 1)
Regression coefficient is the constant "b" in the regression equation that gives the change in the value of the dependent variable equal to the unit change in the independent variable.
Symbolically it can be expressed as:
bₓᵧ= r σ ₓ /σ ᵧ
where x and y are correlated
σ ₓ --> standard deviation of X
σᵧ ---> standard deviation of y
We know that standard deviations is square root value of variance of observations. we also know square root any quantity is always positive or zero.
Using the above fact about standard deviations and correlation coefficient (r) is also positive we see that bₓᵧ is postive.
Hence, Regression cofficient is positive.

The three-dimensional figure shown consists of a cylinder and a right circular cone. The radius of the base is 10 centimeters. The height of the cylinder is 16 centimeters, and the total height of the figure is 28 centimeters. The slant height of the cone is 13 centimeters. Which choice is the best approximation of the surface area of the figure? Use 3.14 to approximate pi.
Answers
Answer:
2,041 square centimeters
Step-by-step explanation:
surface area = (2 × π × r × h) + ((π × r) × (r+ (√(c² + r²))))+(π × r²)
where,
cylinder base radius (r) = 10 cm
height of cylinder (h) = 16 cm
total height = 28 cm
cone height (c) = total height - height of cylinder = 28 - 16 = 12cm
π = 3.14
surface area = (2 × 3.14 × 10 × 16) + ((3.14 × 10) × (10+ (√(12² + 10²))))+(3.14 × 10²)
surface area = 1004.8 + (31.4 * 25.6) + 314
surface area = 2122.64 cm²
therefore the approximate surface area given is 2,041 square centimeters

use a determinant to find the area of the triangle in 2 with vertices (−4,−2), (2,0), and (−2,6).
Answers
The area of the triangle is:
Area = 1/2 * |AB x AC| = 1/2 * |48k| = 24 square units.
How to find area of the triangle?Let A = (-4, -2), B = (2, 0), and C = (-2, 6) be the vertices of the triangle. Then the vectors AB and AC are:
AB = B - A = (2, 0) - (-4, -2) = (6, 2)
AC = C - A = (-2, 6) - (-4, -2) = (2, 8)
The area of the triangle is half the magnitude of the cross product of AB and AC:
Area = 1/2 * |AB x AC|
We can find the cross product by taking the determinant of the following matrix:
| \(i\) j k |
| 6 2 0 |
| 2 8 0 |
Expanding the determinant along the first row, we get:
| \(i\) j k |
|6 2 0 |
|2 8 0 |
= \(i\) * (20 - 80) - j * (60 - 20) + k * (68 - 22)
= 48k
Therefore, the area of the triangle is:
Area = 1/2 * |AB x AC| = 1/2 * |48k| = 24 square units.
