The monopoly price will be given as 110 dollars per unit. Then the total surplus will be 4800 dollars.

The figure below illustrates the market for steel.

If the steel market is competitive, firms can produce steel at a constant marginal cost of $100 per ton.

Therefore, the price of steel is $100 per ton, and 100 tons are produced.

Assume that if all the steel companies consolidate into a monopoly, the monopoly’s marginal cost will fall to $70 per ton.

If the market is controlled by a monopoly, the total surplus will be

The demand curve has to be defined the demand curve will be

P = 150 - 0.5Q

Total revenue, TR = 150Q - 0.5Q^2

MR = 150 - Q

MC = $ 70

The monopolist will maximize profit at MR = MC

150 - Q = 70

=> Q = 80 units

Monopoly price, P = 150 - 0.5 × 80 = $ 110 / unit

Total surplus = (1/2)×(150-110)×80+(110-70)×80

= 1,600 + 3,200

= $ 4,800

The graph is given below.

Step-by-step explanation:

The formula for kinetic energy is as follows:

[tex]\boxed{KE= \frac{1}{2} mv²}[/tex]

where

KE= kinetic energy (J)

m= mass (kg)

v= velocity (m/s)

Given: m= 50 kg, v= 2 m/s

Substituting the given information into the formula:

KE

= ½(50)(2²)

= ½(50)(4)

= 100 J

Answer:

4

Step-by-step explanation:

You have to use Pythagorean Theory which states that a^2+b^2=c^2

It means that:

3^2+b^2=5^2

b^2=25-9

b = root of 16 (25-9=16)

b = 4

Answer:

Step-by-step explanation:

GIVEN:

In order to solve this, you need to isolate the term x on one side of the equation.

First, combine like terms.

[tex]\Longrightarrow: \sf{8x+16x+21=25x+19}[/tex]

Solve.

8x+16x=24x

[tex]\Longrightarrow: \sf{24x+21=25x+19}[/tex]

You have to subtract by 21 from both sides.

[tex]\Longrightarrow: \sf{24x+21-21=25x+19-21}[/tex]

Solve.

[tex]\Longrightarrow: \sf{24x=25x-2}[/tex]

Subtract by 25x from both sides.

[tex]\Longrightarrow: \sf{24x-25x=25x-2-25x}[/tex]

Solve.

-x=-2

Then, you divide by -1 from both sides.

[tex]\Longrightarrow: \sf{\dfrac{-x}{-1}=\dfrac{-2}{-1}}[/tex]

Solve.

Divide the numbers from left to right.

[tex]\sf{\dfrac{-2}{-1}=2 }[/tex]

SOLUTIONS:

[tex]\Longrightarrow: \boxed{\sf{x=2}}[/tex]

I hope this helps. Let me know if you have any questions.

Answer:

[tex]x = 2[/tex]

Given equation:

Combine like terms on the L.H.S and simplify the expression as needed.

Now, rewrite 25x in such a way such that 24x can be repeated on both sides. Clearly, we can rewrite 25x as 24x + x. Then,

Since 24x is being repeated on both sides, we can cancel it.

Finally, subtract 19 on both sides to isolate x.

Therefore, the value of x is 2.

The percent by which the sales of horror books is greater than sales of cookbook is 1.85% approx.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

Given that:

        Genre       number sold

Let we have:
Number of horror books sold = P% greater than number of cookbooks sold

55 = P% greater than 54

55 = 54 + P% of 54

1 = P% of 54

[tex]1 = \dfrac{P}{100} \times 54\\\\P = \dfrac{100}{54} \approx 1.85[/tex]

Thus, the percent by which the sales of horror books is greater than sales of cookbook is 1.85% approx.

The simulation of the customer visit is an illustration of probability

The probability that a customer would visit the coffee shop at least 5 times to win a gift card is  [tex](\frac {11}{12})^{n} - (\frac n{12}) * (\frac {11}{12})^{n - 1} - .......... - ^nC_4 * (\frac 1{12})^4 * (\frac {11}{12})^{n - 4}[/tex]

From the question, we understand that every 12th customer gets a $5 gift card.

This means that the probability that a customer gets a gift card is:

p = 1/12

The probability that a customer would visit the coffee shop at least 5 times to win a gift card is calculated using the following complement rule:

P(x ≥ 5) = 1 - P(x <5)

The equation becomes

P(x ≥ 5) = 1 - P(0) - P(1) - P(2) - P(3) - P(4)

Using the binomial formula

[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]

The equation becomes

[tex]P(x \ge 5) = ^nC_0 * (\frac 1{12})^0 * (1 - \frac 1{12})^{n - 0} - ^nC_1 * (\frac 1{12})^1 * (1 - \frac 1{12})^{n - 1} - .......... - ^nC_4 * (\frac 1{12})^4 * (1 - \frac 1{12})^{n - 4}[/tex]

Simplify

[tex]P(x \ge 5) = (\frac {11}{12})^{n} - (\frac n{12}) * (\frac {11}{12})^{n - 1} - .......... - ^nC_4 * (\frac 1{12})^4 * (\frac {11}{12})^{n - 4}[/tex]

Hence, the estimate that a customer would visit at least 5 times is [tex]P(x \ge 5) = (\frac {11}{12})^{n} - (\frac n{12}) * (\frac {11}{12})^{n - 1} - .......... - ^nC_4 * (\frac 1{12})^4 * (\frac {11}{12})^{n - 4}[/tex]

Step-by-step explanation:

James spun the arrow 30 times which means 30 is the total. In other words, it's your denominator ([tex]\frac{x}{30}[/tex]). It landed on the blue section 12 times which means 12 is the part of the whole. In other words, it's your numerator ([tex]\frac{12}{y}[/tex]). Plug in the entire fraction and you get [tex]\frac{12}{30}[/tex]. Divide 12 by 30 and you get 0.4 or if you divide both the numerator & denominator by 6, you get [tex]\frac{2}{5}[/tex].
