the cournot theory of oligopoly is based on the assumption that each firm believes that rivals will multiple choice increase their output whenever it increases its output. keep their output constant if it changes its output. decrease their output whenever it increases its output. randomly change output whenever it changes its output.
Answers
The cournot theory of oligopoly is based on the assumption that each firm believes that rivals will keep their output constant if it changes its output.
The Cournot theory of oligopoly is an economic model that analyzes the behavior of firms in an oligopolistic market structure. It is named after the French economist Antoine Augustin Cournot.
In the Cournot model, each firm in the market assumes that its rivals will keep their output constant if it changes its own output. This assumption is based on the idea that firms make strategic decisions regarding their production levels, taking into account the likely responses of their competitors.
Under the Cournot model, firms choose their output levels simultaneously, considering the current market conditions and their expectations of how their competitors will react. Each firm acts as a quantity-setter, determining its production quantity based on its own cost structure, market demand, and beliefs about how its rivals will behave.
The assumption that rivals will keep their output constant if one firm changes its output is a simplification used in the Cournot model. It implies that firms do not engage in immediate or aggressive reactions to changes in their competitors' output levels. Instead, they make decisions based on the expectation that their rivals' production decisions will remain unchanged.
By making these assumptions, the Cournot model allows economists to analyze the equilibrium outcomes and market shares that arise in oligopolistic markets. It provides insights into how firms' interdependent behavior affects prices, quantities, and overall market outcomes.
It is important to note that the Cournot model is a simplified representation of real-world oligopoly markets, and the actual behavior of firms may deviate from these assumptions. Nonetheless, the model serves as a useful tool for understanding strategic interactions among firms in oligopolistic industries.

true or false? if false, give a reason.the nth partial sum of an arithmetic sequence is the average of the first and last terms times n.
Answers
The given statement "The nth partial sum of an arithmetic sequence is the average of the first and last terms times n." is False.
The nth partial sum of an arithmetic sequence is not the average of the first and last terms times n. The correct formula for the nth partial sum of an arithmetic sequence is given by:
Sn = (n/2)(a₁ + aₙ),
where Sₙ is the sum of the first n terms, a₁ is the first term, and an is the nth term of the arithmetic sequence.
The formula you mentioned would only hold true if the arithmetic sequence had the same common difference throughout. In that case, the average of the first and last terms would be equal to the common difference, and multiplying it by n would give the correct sum. However, this formula does not hold for arbitrary arithmetic sequences with varying common differences.

She repeated this process for a total of 505050 samples. Here are the sample proportions from her 505050 samples:
Answers
Lilianna's hypothesis that a higher proportion of art students at her university are left-handed can be tested using statistical analysis. She conducted a simulation by taking 50 samples, each consisting of 150 art students, from a population where 10% of the students were left-handed.
She recorded the proportion of left-handed students in each sample to see how likely a sample like the one she obtained (14% left-handed) was to occur by random chance alone. Analyzing the sample proportions from the 50 samples, Lilianna can determine the probability of obtaining a sample proportion as extreme as 14% or more under the assumption of a 10% left-handed population. If the probability is sufficiently low (typically below a predetermined significance level), it would suggest that the observed sample proportion is significantly different from what would be expected by chance, providing evidence to support Lilianna's suspicion.
Using statistical techniques like hypothesis testing, Lilianna can assess the statistical significance of her findings and make conclusions about the proportion of left-handed students among art students at her university. The simulation allows her to understand the likelihood of obtaining her observed sample proportion under the null hypothesis of 10% left-handedness, enabling her to evaluate the validity of her hypothesis.

in a random sample of 200 items, 42 are defective. if the null hypothesis is that 23% of the items in the population are defective, what is the value of zstat?
Answers
The value of z-stat is -0.6721.
What is z stat?
The relationship between a value and the mean of a group of values is quantified by a Z-stat. The Z-stat is calculated using standard deviations from the mean. When a data point's Z-stat is 0, it means that it has the same score as the mean.
One standard deviation from the mean would be indicated by a Z-stat of 1.0. Z-stats can be positive or negative; a positive value means the score is above the mean, while a negative value means it is below the mean.
Solution Explained:
We use the formula,
\(z = \frac{P - \pi }{\sqrt{\frac{\pi (1-\pi )}{200} }}\), where P is the observed proportion, π is the hypothesized proportion
Therefore, P = 42/200 = 0.21 & π = 23/100 = 0.23
Putting the values in
\(z = \frac{0.21 - 0.23 }{\sqrt{\frac{0.23 (1-0.23)}{200} }}\)
After calculating, z-stat is therefore equal to -0.6721

Show that if a is an integer and d is an integer greater than 1, then the quotient and remainder obtained when a is divided by d are a/d anda − da/d, respectively
Answers
To prove that if a is an integer and d is an integer greater than 1, then the quotient and remainder obtained when a is divided by d are [a/d] and a − d[a/d], respectively, we need to use the Division Algorithm.
The Division Algorithm states that for any two integers a and d with d>0, there exist unique integers q and r such that a = dq + r, where r is the remainder and 0 ≤ r < d.
Now, let's apply this algorithm to the given problem. We have:
a = dq + r
We want to express q and r in terms of a and d. To do this, we first divide both sides by d, giving:
a/d = q + r/d
Now, we take the floor function of both sides (i.e., the greatest integer less than or equal to a/d), giving:
[a/d] = q
Next, we multiply both sides by d and subtract from a, giving:
a - d[a/d] = a - dq = r
Therefore, the quotient and remainder obtained when a is divided by d are [a/d] and a − d[a/d], respectively. This proves the statement.

Let S be a closed surface. Use Gauss's theorem to show that if F is a vector field C², then (V x F) ds = 0 S₁
Answers
We have proved that the double integral of (∇ × F) · dS over the closed surface S is equal to zero using Gauss' theorem.
To prove the equation using Gauss' theorem, we need to apply the divergence theorem.
Gauss' theorem states that for a closed surface S enclosing a volume V, the flux of a vector field F across the surface S is equal to the volume integral of the divergence of F over the volume V:
∫∫(F · dS) = ∫∫∫(div F dV).
Now let's apply this theorem to the vector field G = ∇ × F, where ∇ is the del operator (gradient) and × represents the cross product. The divergence of G is given by:
div G = ∇ · (∇ × F).
Using the vector identity ∇ · (∇ × F) = 0, we find that the divergence of G is zero:
div G = 0.
Now we can rewrite the flux integral in terms of the vector field G:
∫∫(G · dS) = ∫∫∫(div G dV) = ∫∫∫(0 dV) = 0.
Since the flux of G across the closed surface S is zero, we can express this result as:
∫∫(∇ × F · dS) = 0.
Finally, noting that the dot product of the curl of F (∇ × F) with the surface normal dS gives the tangential component of (∇ × F), we have:
∫∫(∇ × F · dS) = ∫∫(∇ × F) · dS = 0.
Therefore, the double integral of (∇ × F) · dS over the closed surface S is equal to zero.
Hence, we have proved the desired result using Gauss' theorem.

3×2=6 (which means she can get $6 off of the original price $9.)
9-6= 3 (So now she only has to pay $3 while the other seven people in her group pays the original price $9.)
9×7= 63 (So $9 for the 7 other people equals $63. That is how much they are paying. Now let's add Laurie's amount!)

a cliff overlooking dover lake is experiencing erosion, losing elevation at a rate of 5% every millennium. the cliff's current elevation is 1,519 meters. what will its elevation be in 10 millennia?
Answers
To calculate the cliff's elevation in 10 millennia, we need to use a little bit of math.
Since the cliff is losing elevation at a rate of 5% every millennium, we know that after one millennium, the cliff's elevation will be 95% of its current elevation. Therefore, we can use this formula to calculate the cliff's elevation after three millennia:
1,519 meters * 0.95^10 = 601.83 meters
So, after 10 millennia, the cliff's elevation will be approximately 601.83 meters. This means that the cliff will have lost approximately 917 meters of elevation over the course of 10,000 years due to erosion.
Finally, by applying the formula, we can determine the cliff's elevation in 10 millennia. After doing the calculation, we find that the final elevation will be approximately 744.29 meters.

What is the radius of convergence of a power series function?
Answers
The radius of convergence of a power series function is a positive real number R that determines the interval of values for which the power series converges.
It represents the distance from the center of the power series expansion, within which the series converges. The radius of convergence is determined by the properties of the coefficients in the power series. Specifically, it is defined as the reciprocal of the limit superior of the absolute values of the coefficients. Mathematically, if we have a power series function of the form:
f(x) = ∑(n=0 to ∞) aₙ(x - c)ⁿ
where aₙ represents the coefficients and c is the center of the series, then the radius of convergence R is given by:
R = 1 / lim sup |aₙ|^(1/n)
The power series converges for all values of x within the interval (c - R, c + R). If |x - c| > R, the series diverges.
It's important to note that the radius of convergence can be zero, indicating that the power series only converges at the center point (x = c), or it can be infinite, indicating that the series converges for all values of x.
