Economic Surplus:

Economic surplus, also known in mainstream economics as general welfare or general public welfare or Marshall's surplus (after Alfred Marshall), is one of two related quantities. Pay.

Producer surplus or producer surplus is the amount a producer receives by selling at a market price higher than the lowest price they are willing to sell. This roughly equals profit margin (because producers are usually unwilling to sell at a loss and are generally uninterested in selling at a break-even price).

Total economic surplus = supplier surplus + consumer surplus

On scenario 1, total economic surplus = $40,000 + $2,000 = $42,000

On scenario 2, total economic surplus = $2.25 + $3 = $5.25

On scenario 3, total economic surplus = $0

On scenario 4, total economic surplus = $5 + $5 = $10

The area of the carpet is [tex]2 7/20[/tex] square meters.

The size of a patch on a surface is determined by its area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

To find the area of the carpet, we need to multiply its length by its width.

The mixed numbers must first be transformed into improper fractions:

Length: 21/4 = 9/4

Width: 11/5 = 6/5

Then we can multiply:

Area = length x width

Area = (9/4) x (6/5)

Area = 54/20 or 27/20 square meters

Therefore, the area of the carpet is 27/20 square meters.

The solution for the system of equations is Ax = b as the matrix is invertible (or non-singular) if and only if its determinant is not zero.

To solve a system of equations, we can use matrix algebra. We can write the system of equations in matrix form as follows:

Ax = b

where A is the matrix of coefficients, x is the vector of unknowns (the concentrations), and b is the vector of right-hand sides (the mass inputs).

To solve for x, we can multiply both sides by the inverse of A:

x = [tex]A^{-1}b[/tex]

where [tex]A^{-1}[/tex] is the inverse of A.

However, not all matrices have inverses. A matrix is invertible (or non-singular) if and only if its determinant is not zero. So, before we can solve for x, we need to check if A is invertible by calculating its determinant.

The equation of the line that's vertical to the given line and passes through the point(,6) is y = (-2/3) x28/3.

To find the equation of a line vertical to a given line, we need to use the fact that the pitches of two vertical lines are negative reciprocals of each other.

Let's start by chancing the pitch of the given line. The equation of a line in pitch- intercept form is y = mx b, where m is the pitch and b is the y- intercept. We can rewrite the given line 3x- 2y = 5 in pitch- intercept form by working for y

3x- 2y = 5

- 2y = -3 x 5

y = (3/2) x-5/2

So the pitch of the given line is3/2.

The pitch of a line vertical to this line is the negative complementary of3/2, which is-2/ 3.

Now we can use the point- pitch form of the equation of a line to find the equation of the line that passes through the point(,6) and has pitch-2/ 3. The point- pitch form is

y- y1 = m( x- x1)

where( x1, y1) is the point the line passes through and m is the pitch.

Substituting in the values we know, we get

y- 6 = (-2/3)( x- 5)

Expanding the right side, we get

y- 6 = (-2/3) x10/3

Adding 6 to both sides, we get

y = (-2/3) x28/3

So the equation of the line that's vertical to the given line and passes through the point(,6) is y = (-2/3) x28/3.

The number of pretzels in the beginning was 44 pretzels solving the equation.

An equation is a mathematical statement containing two expressions on either sides which are connected with an equal to sign.

Either sides of an equation is called as left hand side and right hand side.

Let the total number of pretzels = x

Pretzels has been spilled and lost half of the pretzels.

Remaining pretzels = x - x/2

Jane ate 14 pretzels.

Remaining pretzels = x - x/2 - 14

Her sister then ate one more than half the remaining pretzels.

Remaining pretzels = x - x/2 - 14 - [1/2 (x - x/2 - 14) + 1]

Remaining pretzels is 3.

So we get an equation,

x - x/2 - 14 - [1/2 (x - x/2 - 14) + 1] = 3

Solve for x.

x - x/2 - 14 - (x/2 - x/4 - 7 + 1) = 3

x - x/2 - x/2 + x/4 - 14 + 7 - 1 = 3

x/4 - 7 - 1 = 3

A left-skewed histogram is a kind of frequency distribution where the data is concentrated towards the right side of the histogram, with a tail extending towards the left. It is otherwise called a negatively skewed histogram or a left-tailed histogram. In a left-skewed histogram, the mean is not exactly in the middle, demonstrating that the information is slanted toward the lower end of the conveyance. This can happen when the information has a lower bound or a base worth, which makes the tail of the dispersion be pulled towards the left.

What is the Law of Sines?

The Law of Sines, also known as the sine rule, is a trigonometric formula used to find unknown sides or angles in a triangle.

To solve this problem, we can use the Law of Sines, which states that for any triangle ABC,

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the side lengths opposite the corresponding angles A, B, and C, respectively.

Using this formula, we can set up the following proportion:

b/sin(B) = a/sin(A)

Plugging in the values we know, we get:

b/sin(36°) = 6/sin(121°)

Solving for b, we get:

b = (6 sin(36°))/sin(121°)

The hypergeometric distribution should be used instead of the binomial distribution. The correct option is d. Sampling does not involve replacement,

What is binomial distribution ?
The binomial distribution is a probability distribution that describes the probability of getting a certain number of successes in a fixed number of independent trials, where each trial has only two possible outcomes: success or failure.
The probability of getting exactly k successes in n trials with probability of success p is given by the formula:

[tex]P(k) = (n choose k) * p^k * (1 - p)^(n - k)[/tex]

where (n choose k) is the binomial coefficient, which gives the number of ways to choose k items out of n, and is equal to:

[tex](n choose k) = n! / (k! * (n - k)!)[/tex]

where n! represents n factorial, which is the product of all positive integers up to n.

Rounding up to the nearest whole number, the quarterback throws 3 passes in the fourth quarter to complete all of them.

Let's first find out how many passes the quarterback completed in the first three quarters:

18 passes completed out of 33 attempts in the first three quarters

= 18/33 = 0.545 (rounded to three decimal places)

We can then find the total number of passes attempted in the first three quarters by using the fact that the completion rate is the number of completions divided by the number of attempts:

0.545 = 18/x, where x is the total number of attempts in the first three quarters

Solving for x, we get:

x = 18/0.545 = 33

So the quarterback attempted 33 passes in the first three quarters.

Next, we can find the total number of passes attempted in the game by using the completion rate for the entire game:

0.625 = (18 + passes completed in the fourth quarter) / (33 + passes attempted in the fourth quarter)

Multiplying both sides by the denominator:

0.625 × (33 + passes attempted in the fourth quarter) = 18 + passes completed in the fourth quarter

20.625 + 0.625 × passes attempted in the fourth quarter = 18 + passes completed in the fourth quarter

Subtracting 18 and 0.625 × passes attempted in the fourth quarter from both sides, we get:

2.625 = passes completed in the fourth quarter - 0.625 × passes attempted in the fourth quarter

Adding 0.625 × passes attempted in the fourth quarter to both sides, we get:

passes completed in the fourth quarter = 2.625 + 0.625 × passes attempted in the fourth quarter

We don't know the exact number of passes attempted in the fourth quarter, but we can see that for every 1 pass attempted, the quarterback completes 0.625 - 0.545 = 0.08 more passes than in the first three quarters. So to complete all of his passes in the fourth quarter, he needs to attempt:

0.08 × x = 0.08 × 33 = 2.64
