Answers

Answer 1

This could include recommendations for increasing hospital capacity in states with higher rates of Covid-19 deaths, improving coordination and communication between healthcare providers and public health officials, and investing in public health infrastructure to prevent future pandemics.

If we want to investigate the connection between hospital capacity and Covid-19 deaths as a group of public health researchers, we could begin by compiling information on the number of Covid-19 cases and deaths in various states in the United States as well as the hospital capacities in those states.

This could remember information for the quantity of emergency clinic beds, ICU beds, ventilators, and other basic clinical assets accessible in each state. After that, we could look into the connection between Covid-19 deaths and hospital capacity through statistical analysis.

This could include utilizing devices, for example, relapse investigation to decide whether there is a connection between's emergency clinic limit and Coronavirus passings, controlling for other significant factors like populace thickness, socioeconomics, and the general nature of the state's medical services framework.

We could likewise direct meetings with medical services experts and overseers in states with high emergency clinic abilities to study how their clinics have had the option to answer the Coronavirus pandemic. Best practices, difficulties encountered, and opportunities for improvement might be discussed here. Finally, we might be able to share our findings with policymakers and other stakeholders to help them make decisions about the capacity of the healthcare system and how to respond to a pandemic.    

This could include recommending that hospital capacity be increased in states with higher rates of Covid-19 deaths, that healthcare providers and public health officials better coordinate and communicate, and that money be invested in public health infrastructure to prevent future pandemics.

Answers

Thus, if we choose z to be a negative value instead of a positive value, then we would get the opposite inequality.

The statement "For any positive value z, it is always true that P(Z > z) > P(T > z), where Z~ N(0,1), and T ~ Taf, for some finite df value" is false. This is because both normal and t distributions have a symmetric distribution.

Explanation: Let Z be a random variable that has a standard normal distribution, i.e. Z ~ N(0, 1). Then we have, P(Z > z) = 1 - P(Z < z) = 1 - Φ(z), where Φ is the cumulative distribution function (cdf) of the standard normal distribution. Similarly, let T be a random variable that has a t distribution with n degrees of freedom, i.e. T ~ T(n).Then we have, P(T > z) = 1 - P(T ≤ z) = 1 - F(z), where F is the cdf of the t distribution with n degrees of freedom. The statement "P(Z > z) > P(T > z)" is equivalent to Φ(z) < F(z), for any positive value of z. However, this is not always true. Therefore, the statement is false. The reason for this is that both normal and t distributions have a symmetric distribution. The standard normal distribution is symmetric about the mean of 0, and the t distribution with n degrees of freedom is symmetric about its mean of 0 when n > 1.

given the function f(x) = 0.5|x – 4| – 3, for what values of x is f(x) = 7?

Answers

Therefore, the values of x for which function f(x) = 7 are x = 24 and x = -16.

To find the values of x for which f(x) is equal to 7, we can set up the equation:

0.5|x – 4| – 3 = 7

First, let's isolate the absolute value term by adding 3 to both sides:

0.5|x – 4| = 10

Next, we can remove the coefficient of 0.5 by multiplying both sides by 2:

|x – 4| = 20

Now, we can split the equation into two cases, one for when the expression inside the absolute value is positive and one for when it is negative.

Case 1: (x - 4) > 0:

In this case, the absolute value expression becomes:

x - 4 = 20

Solving for x:

x = 20 + 4

x = 24

Case 2: (x - 4) < 0:

In this case, the absolute value expression becomes:

-(x - 4) = 20

Expanding the negative sign:

-x + 4 = 20

Solving for x:

-x = 20 - 4

-x = 16

Multiplying both sides by -1 to isolate x:

(1 point) Test the claim that the two samples described below come from populations with the same mean. Assume that the samples are independent simple random samples. Use a significance level of 0.03.

Answers

Since the two samples come from populations with the same mean, we can use the two-sample t-test to test the hypothesis. The null hypothesis for this test is that the two samples come from populations with the same mean, and the alternative hypothesis is that the two samples come from populations with different means.

Here are the steps to test the hypothesis:

Step 1: State the null and alternative hypotheses. H0: μ1 = μ2 (the two samples come from populations with the same mean)Ha: μ1 ≠ μ2 (the two samples come from populations with different means)

Step 2: Determine the level of significance (α). α = 0.03

Step 3: Determine the critical value(s). Since the test is a two-tailed test, we need to find the critical values for the t-distribution with degrees of freedom (df) equal to the sum of the sample sizes minus two (n1 + n2 - 2) and a level of significance of 0.03. Using a t-distribution table or calculator, we get a critical value of ±2.594.

Step 4: Calculate the test statistic. The test statistic for the two-sample t-test is given by: t = (x1 - x2) / (s1²/n1 + s2²/n2)^(1/2) where x1 and x2 are the sample means, s1 and s2 are the sample standard deviations, and n1 and n2 are the sample sizes.

Step 5: Determine the p-value. Using a t-distribution table or calculator, we can find the p-value corresponding to the test statistic calculated in step 4.

Step 6: Make a decision. If the p-value is less than the level of significance (α), we reject the null hypothesis; otherwise, we fail to reject the null hypothesis.

Hypotheses:

H0: µ1 = µ2 (the two population means are equal)

H1: µ1 ≠ µ2 (the two population means are not equal)

Here, we are using a two-tailed test at a significance level of α = 0.03. Thus, the critical value for rejection region is obtained as follows:

α/2 = 0.03/2

= 0.015

The degrees of freedom is given by:

(n1 - 1) + (n2 - 1) = (15 - 1) + (12 - 1)

3. Using Divergence theorem, evaluate f Eds, where E = xi + yj + zk, over the cube bounded by x = 0, x = 1, y = 0, y = 1, z = 0, z = 1. [6]

Answers

The flux of the vector field E over the given cube is 3.

The Divergence theorem relates the flux of a vector field across a closed surface to the divergence of the vector field within the volume enclosed by that surface. Using the Divergence theorem, we can evaluate the flux of a vector field over a closed surface by integrating the divergence of the field over the enclosed volume.

In this case, the vector field is given by E = xi + yj + zk, and we want to find the flux of this field over the cube bounded by x = 0, x = 1, y = 0, y = 1, z = 0, z = 1. To evaluate the flux using the Divergence theorem, we first need to calculate the divergence of the vector field. The divergence of E is given by: div(E) = ∂x(xi) + ∂y(yj) + ∂z(zk) = 1 + 1 + 1 = 3

Now, we can apply the Divergence theorem: ∬S E · dS = ∭V div(E) dV

The cube is bounded by six surfaces, the integral on the left side of the equation represents the flux of the vector field E over these surfaces. On the right side, we have the triple integral of the divergence of E over the volume of the cube.

As the cube is a unit cube with side length 1, the volume is 1. Therefore, the integral on the right side simply evaluates to the divergence of E multiplied by the volume: ∭V div(E) dV = 3 * 1 = 3

Thus, the flux of the vector field E over the given cube is 3.

Answers

The sum of the probabilities is not equal to one, the table does not represent a probability distribution, so option D is the correct answer.

The statement that explains that the table does not represent a probability distribution is D. The sum of the probabilities is 8/3.

This statement explains that the probabilities do not add up to one, which is a requirement for a probability distribution. Therefore, it is not a probability distribution. If a table is given with probabilities and it is required to identify whether it represents a probability distribution or not, we must check the probabilities whether they meet the following conditions or not.

The sum of all probabilities should be equal to 1.All probabilities should be greater than or equal to zero.If any probability is greater than 1, then it is not a probability, so the probability table does not represent a probability distribution.The given probabilities have different denominators, this condition alone is not enough to reject it as probability distribution and is also a common error while creating the probability table.

An event's probability is a numerical value that reflects how likely it is to occur. Probabilities are always between zero and one, with zero indicating that the event is impossible and one indicating that the event is certain.

The sum of the probabilities of all possible outcomes for a particular experiment is always equal to one.The probabilities in the table represent the likelihood of the event happening and must add up to 1.

For example, the probability of rolling a die and getting a 1 is 1/6 because there are six possible outcomes and only one of them is a 1.The probability distribution can be used to determine the likelihood of certain outcomes. The sum of all probabilities must be equal to one.

The probability distribution function is also used in statistics to calculate the mean, variance, and standard deviation of a random variable. A probability distribution that meets the required conditions is called a discrete probability distribution. It is a distribution where the probability of each outcome is defined for discrete values.

The probability of randomly selecting a class section from the population with an average G.P.A. less than 2.50 is approximately 24.91%. The probability of randomly selecting a class section from the population with an average G.P.A. greater than 3.00 is approximately 6.84%.

To calculate the probabilities and the average GPA for the given questions, we can use the sample mean (2.66) and sample standard deviation (0.23) from the Average G.P.A. data, assuming they represent the population.

1. The probability of randomly selecting a class section from the population with an average G.P.A. less than 2.50 can be calculated using the z-score formula and the standard normal distribution.

The z-score is (2.50 - 2.66) / 0.23 = -0.6957. Using a standard normal distribution table or software, we find the probability to be approximately 24.91%.

2. The probability of randomly selecting a class section from the population with an average G.P.A. greater than 3.00 can be calculated using the z-score formula and the standard normal distribution.

The z-score is (3.00 - 2.66) / 0.23 = 1.4783. Using a standard normal distribution table or software, we find the probability to be approximately 6.84%.

3. The probability of randomly selecting a class section from the population with an average G.P.A. between 2.35 and 2.80 can be calculated by finding the area under the standard normal curve between the corresponding z-scores.

The z-scores for 2.35 and 2.80 are (-0.9130) and (0.6522) respectively. Using a standard normal distribution table or software, we find the probability to be approximately 46.20%.

4. To compute the average G.P.A. that represents the 90th percentile of all Introduction to Statistics class sections over the past five years, we need to find the corresponding z-score. Using a standard normal distribution table or software, we find the z-score to be approximately 1.2816.

We can then calculate the average G.P.A. using the formula: average G.P.A. = (z-score * standard deviation) + mean.

Substituting the values, we get (1.2816 * 0.23) + 2.66 = 2.9668. Therefore, the average G.P.A. that represents the 90th percentile is approximately 2.97.

Find the line integral of f(x,y)=ye x 2
along the curve r(t)=4ti−3tj,−1≤t≤1. The integral of f is

Answers

The value of the line integral of `f(x, y) = ye^(x^2)`along the curve `r(t) = 4ti - 3tj, -1 ≤ t ≤ 1` is `-0.0831255sqrt(145)` (approx).

The given integral is of the form:

Line integral is defined as the integration of a function along a curve. The given integral is a line integral that is the integral of the function along a given curve.  Therefore, the line integral of

`f(x, y) = ye^(x^2)`

along the curve

`r(t) = 4ti - 3tj, -1 ≤ t ≤ 1` is:

We know that,

Let us evaluate

`f(r(t))` first.`f(r(t)) = y(t)e^(x(t)^2)`

where,

`x(t) = 4t`, `y(t) = -3t`

So, `f(r(t)) = (-3t)e^((4t)^2)`

To find the line integral of

`f(x, y) = ye^(x^2)`

along the curve

`r(t) = 4ti - 3tj, -1 ≤ t ≤ 1`.

we integrate

`f(r(t))` with respect to `t`. Hence,

`∫f(r(t))dt` (for t = -1 to t = 1)`= ∫_(-1)^(1) f(r(t))|r'(t)|dt`

since `ds = |r'(t)|dt`)`= ∫_(-1)^(1) [(-3t)e^((4t)^2)]|r'(t)|dt`

substituting `f(r(t))` with the corresponding value

`= ∫_(-1)^(1) [(-3t)e^((4t)^2)]sqrt(16+9)dt`

(substituting `|r'(t)|` with `sqrt(16+9)`)`=

∫_(-1)^(1) [-3tsqrt(145)e^(16t^2)] dt`

Thus, the integral of f is

`∫_(-1)^(1) [-3tsqrt(145)e^(16t^2)] dt = (-sqrt(145)/4)[e^(16t^2)]_(-1)^(1)`

Let's evaluate

`e^(16)` and `e^(-16)` now

.`e^(16) = 8.8861 xx 10^6`

`e^(-16) = 1.1254 xx 10^(-7)`

Therefore,

`(-sqrt(145)/4)[e^(16t^2)]_(-1)^(1)`= `(-sqrt(145)/4)

[e^(16) - e^(-16)]`

= `(-sqrt(145)/4)[8.8861 xx 10^6 - 1.1254 xx 10^(-7)]`

= `(-sqrt(145)/4)(8.8860985 xx 10^6 - 1.1254 xx 10^(-7))

= -0.0831255 sqrt(145)`

Hence, the value of the line integral of `f(x, y) = ye^(x^2)`along the curve `r(t) = 4ti - 3tj, -1 ≤ t ≤ 1` is `-0.0831255sqrt(145)` (approx).

On Saturday, some adults and some children were in a theatre. The ratio of the number of adults to the number of children was 7:2 Each person had a seat in the Circle or had a seat in the Stalls. 4 of the children had seats in the Stalls. 5 124 children had seats in the Circle. There are exactly 3875 seats in the theatre. On this Saturday, what percentage of the seats had people sitting on them?​

Answers

On this Saturday, the percentage of the seats that had people sitting on them was 72%.

What is the percentage?

The percentage refers to the ratio or proportion of one value or variable compared to another.

The percentage is computed as the quotient of the division of one proportional value with the whole value, multiplied by 100.

The ratio of adults to children in the theater = 7:2

The sum of ratios = 9 (7 + 2)

The proportion of children who had seats in the Stalls = ⁴/₅ = 0.8 or 80%

The number of children who had seats in the Circle = 124

124 = 0.2 (1 - 0.8)

Proportionately, the total number of children who had seats in the Stalls or the Circle = 620 (124 ÷ 0.2)

The number of adults who had seats in the Stalls or the Circle in the theater =2,170 (620 ÷ 2 × 7)

The total number of adults and children with seats in the theater = 2,790 (620 ÷ 2 × 9) or (2,170 + 620)

The total number of seats in the theater = 3,875

The percentage of the seats with people sitting on them = 72%(2,790÷3,875 × 100).

Thus, the theater was seated to 72% capacity.

Consider a binomial experiment with n = 11 and p = 0.5. a. Compute ƒ(0) (to 4 decimals). f(0) = b. Compute f(2) (to 4 decimals). ƒ(2) = c. Compute P(x ≤ 2) (to 4 decimals). P(x ≤ 2) = d. Compute

Answers

a. ƒ(0) is approximately 0.0004883. b. ƒ(2) is approximately 0.0273438. c. P(x ≤ 2) is approximately 0.0332031. d. P(x > 2) is approximately 0.9667969.

a. To compute ƒ(0), we use the formula for the probability mass function of a binomial distribution:

ƒ(x) = C(n, x) * p^x * (1-p)^(n-x)

Where C(n, x) represents the binomial coefficient, given by C(n, x) = n! / (x!(n-x)!).

In this case, we have n = 11 and p = 0.5. Plugging in these values, we get:

ƒ(0) = C(11, 0) * 0.5^0 * (1-0.5)^(11-0)

= 1 * 1 * 0.5^11

≈ 0.0004883 (rounded to 4 decimals)

Therefore, ƒ(0) is approximately 0.0004883.

b. To compute ƒ(2), we use the same formula:

ƒ(2) = C(11, 2) * 0.5^2 * (1-0.5)^(11-2)

Plugging in the values, we get:

ƒ(2) = C(11, 2) * 0.5^2 * 0.5^9

= 55 * 0.25 * 0.001953125

≈ 0.0273438 (rounded to 4 decimals)

Therefore, ƒ(2) is approximately 0.0273438.

c. To compute P(x ≤ 2), we need to sum the probabilities from ƒ(0) to ƒ(2):

P(x ≤ 2) = ƒ(0) + ƒ(1) + ƒ(2)

Using the previous calculations:

P(x ≤ 2) = 0.0004883 + ƒ(1) + 0.0273438

To find ƒ(1), we can use the formula:

ƒ(1) = C(11, 1) * 0.5^1 * (1-0.5)^(11-1)

Plugging in the values, we get:

ƒ(1) = 11 * 0.5 * 0.000976563

≈ 0.0053711 (rounded to 4 decimals)

Now we can compute P(x ≤ 2):

P(x ≤ 2) = 0.0004883 + 0.0053711 + 0.0273438

≈ 0.0332031 (rounded to 4 decimals)

Therefore, P(x ≤ 2) is approximately 0.0332031.

d. To compute P(x > 2), we can subtract P(x ≤ 2) from 1:

P(x > 2) = 1 - P(x ≤ 2)

= 1 - 0.0332031

≈ 0.9667969 (rounded to 4 decimals)

Therefore, P(x > 2) is approximately 0.9667969.

find the volume of the solid whose base is bounded by the circle x^2 y^2=4

Answers

the volume of the solid whose base is bounded by the circle x²y² = 4 is 0.

The equation of a circle in the coordinate plane can be written as(x - a)² + (y - b)² = r², where the center of the circle is (a, b) and the radius is r.

The equation x²y² = 4 can be rewritten as:y² = 4/x².

Therefore, the graph of x²y² = 4 is the graph of the following two functions:

y = 2/x and y = -2/x.

The line connecting the points where y = 2/x and y = -2/x is the x-axis.

We can use the washer method to find the volume of the solid obtained by rotating the area bounded by the graph of y = 2/x, y = -2/x, and the x-axis around the x-axis.

The volume of the solid is given by the integral ∫(from -2 to 2) π(2/x)² - π(2/x)² dx

= ∫(from -2 to 2) 4π/x² dx

= 4π∫(from -2 to 2) x⁻² dx

= 4π[(-x⁻¹)/1] (from -2 to 2)

what is the relative class frequency for the $25 up to $35 class?

Answers

The relative class frequency for the $25 up to $35 class is the proportion of observations within that price range compared to the total number of observations. It provides a measure of the relative occurrence of values within that specific class.

To calculate the relative class frequency for the $25 up to $35 class, we need to consider the total number of observations falling within that price range and compare it to the overall number of observations. Let's assume we have a dataset of prices for different products.

First, we determine the number of observations falling within the $25 up to $35 class. This involves identifying the values that are greater than $25 but less than or equal to $35. Let's say we find 100 such observations within this range.

Next, we calculate the total number of observations in the dataset. Let's assume there are 500 observations in total.

To find the relative class frequency, we divide the number of observations within the $25 up to $35 class (100) by the total number of observations (500) and multiply it by 100 to convert it to a percentage.

Relative Class Frequency = (Number of Observations in Class / Total Number of Observations) * 100

In this case, the relative class frequency for the $25 up to $35 class would be (100 / 500) * 100 = 20%.

This means that approximately 20% of the total observations in the dataset fall within the $25 up to $35 price range. It provides a relative measure of the occurrence of values within this specific class, allowing for comparisons with other price ranges or classes within the dataset.

Answers

The values of $no$ and $pa$ are $no = -28m$ and $pa = 123.6m$, respectively.

Given: $Ma=125m, n=100$We need to find the values of $no$ and $pa.$ We know that, for a right triangle, we can use Pythagoras theorem. According to Pythagoras Theorem, In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

That is,$$hypotenuse^2 = base^2 + height^2$$Or, $$c^2 = a^2 + b^2$$,

Where c is the hypotenuse and a and b are the base and height respectively.

Here, we have $Ma=125m$ as the hypotenuse. Let's consider $no$ as base and $pa$ as height.

Therefore, from the Pythagoras theorem, we have;$$Ma^2 = no^2 + pa^2$$

Substitute the given values and solve for $no$ and $pa$.$$(125m)^2 = no^2 + pa^2$$We know that $n=100$ and, we can also use the formula of $sin(\theta) = \frac{opposite}{hypotenuse}$ and $cos(\theta) = \frac{adjacent}{hypotenuse}$ to find the values of $no$ and $pa$.

Here, we have; $$sin(\theta) = \frac{pa}{Ma}$$$$cos(\theta) = \frac{no}{Ma}$$

Substituting the given values, we get;$$sin(\theta) = \frac{pa}{125m}$$$$cos(\theta) = \frac{no}{125m}$$

Rearranging the above expressions, we have;$$pa = Ma \cdot sin(\theta)$$$$no = Ma \cdot cos(\theta)$$

Substituting the given values of $Ma = 125m$ and $n = 100$,

we get:$$pa = 125m \cdot sin(100)$$$$no = 125m \cdot cos(100)$$

Therefore, $pa = 123.6m$ (rounded to one decimal place) and $no = -28m$ (rounded to the nearest integer).

Hence, the values of $no$ and $pa$ are $no = -28m$ and $pa = 123.6m$, respectively.

how does restricting the range of a variable affect the correlation coefficient?

Answers

Restricting the range of a variable affects the correlation coefficient by making it appear stronger than it actually is.

The correlation coefficient is a statistical measure used to show how strong and what direction a relationship is between two variables. Correlation coefficients can range from -1 to +1. The closer the correlation coefficient is to -1 or +1, the stronger the relationship. The closer the coefficient is to 0, the weaker the relationship.

What does it mean to restrict the range of a variable, Restricting the range of a variable means that you only consider a portion of the possible values for that variable. When you restrict the range of a variable, you are excluding some of the data from your analysis. This can make the correlation coefficient appear stronger than it actually is because you are only looking at a portion of the data.

Select the correct choice below and, if necossary, fill in the answer boxes to complete your choice A. The absolute maximum, which occurs twice, is at x= and x= (Use ascending order) B. The absolute maximum is at x= C. There is no absolute maximum.

Answers

The absolute maximum and minimum for the function f(x) = x^4 - 4x^3 - 10 are as follows: (A) on the interval [-1,1], there is no absolute maximum; (B) on the interval [0,4], the absolute maximum occurs at x = 2; (C) on the interval [-1,2], the absolute maximum occurs at x = 2.

To find the absolute maximum and minimum of the function, we need to analyze the critical points and the endpoints of the given intervals.
(A) On the interval [-1,1], we first find the critical points by taking the derivative of f(x) and setting it equal to zero: f'(x) = 4x^3 - 12x^2 = 0. Solving this equation, we get x = 0 and x = 3. However, since 3 is not within the interval [-1,1], there are no critical points in the interval. Therefore, we check the endpoints of the interval, which are f(-1) = -14 and f(1) = -12. The function does not have an absolute maximum in this interval.
(B) On the interval [0,4], we find the critical points by setting f'(x) = 0: 4x^3 - 12x^2 = 0. Solving this equation, we find x = 0 and x = 3. However, 0 is not within the interval [0,4]. Therefore, we check the endpoints: f(0) = -10 and f(4) = 26. The absolute maximum occurs at x = 2, where f(2) = 2^4 - 4(2)^3 - 10 = 2.
(C) On the interval [-1,2], we find the critical points by setting f'(x) = 0: 4x^3 - 12x^2 = 0. Solving this equation, we get x = 0 and x = 3. However, 3 is not within the interval [-1,2]. We check the endpoints: f(-1) = -14 and f(2) = -10. The absolute maximum occurs at x = 2, where f(2) = 2^4 - 4(2)^3 - 10 = 2.
Therefore, the answers are: (A) No absolute maximum, (B) Absolute maximum at x = 2, and (C) Absolute maximum at x = 2.

What is the area of the region in the first quadrant that is bounded above by y=sqrt x and below by the x-axis and the line y=x-2?

Answers

The area of the given region in the first quadrant is `32/3` square units.

The given region in the first quadrant bounded above by[tex]`y = \sqrt(x)`[/tex] and below by the x-axis

and the line `y = x - 2`. We can compute the area of the region by finding the points of intersection of the curves. These curves intersect at the point `(4,2)`.

Hence, the area of the given region in the first quadrant bounded above by[tex]`y = \sqrt(x)`[/tex] and below by the x-axis and the line

`y = x - 2` is:

[tex]\int[0,4](x - 2)dx + \int[4,16]\sqrt(x)dx[/tex]

=[tex][x^2/2 - 2x][/tex]

from 0 to 4 + [tex][2/3 * x^_(3/2)][/tex]

from 4 to 16= (16 - 8) + (32/3 - 8/3)

= 8 + 8/3

= 24/3 + 8/3

= 32/3.

Integer/profit/LR supply Consider a perfectly competitive industry with 48 identical firms. The short run and long run cost functions of a typical firm are: CSR(q) = 4q + 27% so that MCSR(q) = 4 +6q?. Cur(q) = 500+ 4q + 27% so that MC R(q) = 4 +6q? Market demand for the industry's product is QD = 292-P, where P is the price of the product and Q is the total quantity demanded. For part (b), pretend that the number of firms is an integer number even if it is not. In other words, even if you have derived an answer with a non-integer number for the number of firms, consider it as an integer (e.g., if the number of firms is 3.7, then there are 3.7 number of firms in the industry). (b) In the long-rm, there are a potentially infinite number of identical firms that can enter/exit the industry. What is the long-run market supply curve for the industry? Compute the long- run equilibrium price. How much does each firm produce in this long-run equilibrium, and how many active firms are in the market? What is the profit for each firm? Please explain how you proceed. (c) Apparently, the mumber of firms in the industry has to be an integer number. So we now discard the assumption for part (b), and we put an additional restriction that the number of firms should be integer. Compute the long-run equilibrium price. How much does each firm produce in this long-run equilibrium and how many active firms are there in the market? What is the profit for each firm?
