Inequality 1:
Inequality 2:

Based on the provided payoff , if John chooses to "Turn," Paul will choose to "Drive Straight," and Paul's payoff will be 20. Therefore, the correct answer is option b: Drive Straight, 20.

To determine Paul's optimal decision and payoff, let's analyze the payoff table step by step:

If John chooses "Turn" and Paul chooses "Turn":

John's payoff: 10

Paul's payoff: 10

If John chooses "Turn" and Paul chooses "Drive Straight":

John's payoff: 20

Paul's payoff: 5

If John chooses "Drive Straight" and Paul chooses "Turn":

John's payoff: 5

Paul's payoff: 20

If John chooses "Drive Straight" and Paul chooses "Drive Straight":

John's payoff: 0

Paul's payoff: 0

Considering the competing interests of John and Paul, Paul's objective is to maximize his own payoff while minimizing John's payoff. In this scenario, Paul will choose the option that yields him the highest payoff while preventing John from getting a higher payoff.

Comparing the payoffs, if John chooses "Turn," Paul will choose "Drive Straight" because it gives him a higher payoff of 20 compared to 10 if he chooses "Turn." By choosing "Drive Straight," Paul can maximize his own payoff while preventing John from achieving a higher payoff.

Therefore, the correct answer is b: Drive Straight, 20.

The equation of the tangent line to the Witch of Agnesi at a given point (x0, y0) is:  \(\(y - y_0 = \frac{-64a^3x_0}{(x_0^2 + 4a^2)^2}(x - x_0)\)\)

The tangent lines to the curve called the Witch of Agnesi at a given point can be determined by finding the derivative of the curve and evaluating it at that point.

To find the equation of a tangent line, we need the derivative of the curve. The equation of the Witch of Agnesi is given by:

\(y = \frac{8a^3}{x^2 + 4a^2}\)

where 'a' is a constant that determines the shape of the curve.

Taking the derivative of y with respect to x, we can find the slope of the tangent line:

\(\frac{dy}{dx} = \frac{-64a^3x}{(x^2 + 4a^2)^2}\)

Let's assume we want to find the tangent lines at the point (x0, y0). We can substitute these coordinates into the derivative expression:

\(\frac{dy}{dx}\Bigr|_{x=x_0} = \frac{-64a^3x_0}{(x_0^2 + 4a^2)^2}\)

This gives us the slope of the tangent line at the point (x0, y0).

Now, using the point-slope form of a line, we can write the equation of the tangent line:

\(y - y_0 = \frac{dy}{dx}\Bigr|_{x=x_0}(x - x_0)\)

Substituting the values we obtained earlier, the equation of the tangent line becomes:

\(y - y_0 = \frac{-64a^3x_0}{(x_0^2 + 4a^2)^2}(x - x_0)\)

This equation represents the tangent line to the Witch of Agnesi at the point (x0, y0).

Answer:

The process capability index for this system is 0.9103

Step-by-step explanation:

Upper specification = 1.649 inches

Lowe Specification = 1.507 inches

Mean = 1.57 inches

Standard Deviation = 0.026 inches

Process Capability Index = PCI

PCI = (Upper specification - lower specification)/6(standard deviation)

So, we get,

PCI = (1.649 - 1.507)/((6)(0.026))

PCI = 0.142/0.156

PCI = 0.9102564

To four decimal places, we get,

PCI = 0.9103

The balance in the account 10 years after Jakie stopped her monthly payments, with the interest compounding quarterly at a rate of 6.9% per year, is approximately R373,185.53.

To calculate the balance in the account 10 years after Jakie stopped her monthly payments, we need to consider two periods: the period when she was making monthly payments and the period after she stopped making payments.

During the period when she was making monthly payments, the interest was compounded monthly at a rate of 6.9% per year. We can use the formula for compound interest to calculate the future value of the monthly payments. Using the formula:

Future Value = Payment * [(1 + interest rate/compounding periods)^(compounding periods * number of years) - 1] / (interest rate/compounding periods)

Plugging in the values: Payment = R4,500 , Interest rate = 6.9% = 0.069, Compounding periods = 12 (monthly)

Future Value = R4,500 * [(1 + 0.069/12)^(12 * 4) - 1] / (0.069/12)

Future Value = R280,192.52

Now, we need to calculate the balance after 10 years when the compounding periods change to quarterly. We can use the same formula for compound interest, but with a different compounding period.

Future Value = Previous Balance * (1 + interest rate/compounding periods)^(compounding periods * number of years)

Plugging in the values: Previous Balance = R280,192.52, Interest rate = 6.9% = 0.069, Compounding periods = 4 (quarterly), Number of years = 10

Future Value = R280,192.52 * (1 + 0.069/4)^(4 * 10)

Future Value = R526,618.01. Therefore, the balance in the account 10 years after Jakie stopped her monthly payments is A. R373 185,53.

The correct answer is C) intensively use natural resources. This is because Chile's comparative advantage lies in its abundant natural resources, and it should therefore focus on producing and exporting goods that make intensive use of those resources.

According to the Heckscher-Ohlin Theorem, countries will tend to specialize in and export goods that make intensive use of their abundant factors of production and import goods that make intensive use of their scarce factors of production. In this case, Brazil is capital abundant and Chile is natural resource abundant. Timber is natural resource intensive, meaning that it requires a lot of natural resources to produce, while computers are capital intensive, meaning that they require a lot of capital to produce.

Therefore, according to the Heckscher-Ohlin Theorem, Chile should export goods that make intensive use of its abundant factor of production, which is natural resources.

Answer:

823

Method 1

Break the three numbers into hundreds, tens and units, then add these separately (starting with the units)

197 = 1 hundred, 9 tens, 7 units

203 = 2 hundreds, 0 tens, 3 units

423 = 4 hundreds, 2 tens, 3 units

Units: 7 + 3 + 3 = 13

Tens: 9 + 2 = 11 tens = 110

Hundreds: 1 + 2 + 4 = 7 hundreds = 700

Add these together: 700 + 110 + 13 = 823

Method 2

First add 203 to 197:

Borrow the 3 from 203 and add it to 197:  197 + 3 = 200

Add the remaining 200:  200 + 200 = 400

Now add 423 to 400:  400 + 423 = 823

⇒ 203 + 197 + 423 = (203 + 197) + 423

                                = 400 + 423

Due to availability of evidence we support the claim that the bags are underfilled, therefore we reject the null hypothesis, under the condition bag filling machine works correctly at the 443.0 gram setting.

The null hypothesis is that the bags are considered not underfilled and the other alternative hypothesis is that the bags are underfilled.

The level of significance is 0.05 which means that we have  to reject the null hypothesis if the p-value  < 0.05.
Given,
The sample size is 48 and the sample mean is 439 grams. Standard deviation = 25 grams.
The test statistic is evaluated
Z = (x'- μ) / (σ / √n)

Here,
x' = sample mean,
μ = hypothesized population mean,
σ = population standard deviation,
n = sample size.

Staging the values we get:

Z = (439 - 443) / (25 / √48)
= -2.45

The p-value can be calculated applying a Z-table.
Z = -2.45 is approximately 0.0071.

Since the p-value (0.0071) is less than the level of significance (0.05), we reject the null hypothesis.

The question requires us to find the inverse demand for a homogeneous-product Stackelberg duopoly, given the cost structures for the leader and follower are Cl(ql) = 4000ql and Cf(qf) = 6000qf respectively.T

he inverse demand for a homogeneous-product Stackelberg duopoly is p = 16000 - 4q where p is the price and q is the quantity.

Substituting the given value of inverse demand in the above equation we get:16000 - 4q = p... equation 1

Also, the total quantity demanded in the market is the sum of the quantity demanded by both the players.

Hence, we can say that,Total quantity demanded, Q = qL + qF, where qL is the quantity demanded by the leader and qF is the quantity demanded by the follower.

Now let us find the reaction function for the follower.

Follower's Reaction Function: We know that for a homogeneous-product Stackelberg duopoly, the leader decides its production quantity before the follower.

Hence, the leader's quantity is a fixed quantity.Using the leader's quantity the follower's best response function can be given as:qF = (p - CF(qF))/2 ... equation 2

Now let us find the leader's reaction function.

Leader's Reaction Function:For the leader, the best response function is obtained by maximising its profits.

The profit function for the leader can be written as:πL = (p - CL(qL))qL

Substituting the given values, we get:

πL = (16000 - 4qL - 4000qL)qL

= (12000 - 4qL)qL

= 3000 - 0.25qL ... equation 3

The total quantity demanded is given as Q = qL + qF

Substituting equation 2 and 3 in the above equation and solving for qL, we get:

qL + qF = qL + (p - CF(qF))/2

= 3000 - 0.25qLqL + (16000 - 4qF - 6000qF)/2

= 3000 - 0.25qL5qF + 0.5qL = 9000qF

= 1800 - 0.1qL ... equation 4

Substituting equation 4 in equation 2 and solving for qF, we get:

qF = (16000 - 4q - 6000(1800 - 0.1q))/2qF = 4800 - 0.05q ... equation 5

Substituting the value of qL in equation 1, we get:

16000 - 4q = 16000 - 4(26000 - 3.33Q)q

= 665Q + 8000

Now that we have found the reaction function for both the players, let's find their equilibrium quantities

Quantity demanded by the leader, qL = 26000 - 3.33Q

Quantity demanded by the follower, qF = 665Q + 8000

The total quantity demanded in the market is Q = qL + qF = 33133/7

The largest possible area for the rectangle is (64/9)√6, which corresponds to option (a).

To find the largest possible area for a rectangle with its base on the x-axis and upper vertices on the curve y = 8 - x^2, we will follow these steps:

1. Write down the area function: The area A of the rectangle can be expressed as A = x(8 - x^2) = 8x - x^3.
2. Find the critical points: To maximize the area, we need to find the critical points of the area function. To do this, we take the first derivative of A with respect to x and set it equal to 0.
  dA/dx = 8 - 3x^2 = 0
3. Solve for x: To find the critical points, we solve the equation from Step 2 for x:
  3x^2 = 8
  x^2 = 8/3
  x = ±√(8/3)
4. Determine which critical point maximizes the area: Since the area cannot be negative, only the positive value of x is relevant. Therefore, x = √(8/3).
5. Find the corresponding y-value: Now we plug the x-value back into the curve equation y = 8 - x^2 to find the y-value of the upper vertices:
  y = 8 - (√(8/3))^2 = 8 - 8/3 = 16/3
6. Calculate the maximum area: Finally, we multiply the base (x-value) by the height (y-value) to find the largest possible area for the rectangle:
  A_max = x * y = (√(8/3)) * (16/3) = (64/9)√6

So, the largest possible area for the rectangle is (64/9)√6, which corresponds to option (a).

Since the assumption that the vis are linearly dependent is false as a result of this contradiction, they are in fact linearly independent.

If no vector in a collection of vectors can be written as a linear combination of the other vectors in the set, the set is said to be linearly independent. The set is said to be linearly dependent if any of the vectors can be represented as a linear combination of the others. If you write a collection of vectors as the columns of the matrix A and solve Ax = 0, you can tell if the vectors are linearly independent. The vectors are linearly dependent if there are any non-zero solutions. They are linearly independent if x = 0 is the sole viable answer.

You want to show v1,…,vn are linearly independent.

Suppose they are not.

Then there are scalars c1,…,cn (not all zero) so that c1v1+…+cnvn=0. Then

The inductance L can be expressed as L = ℜN^2, which is an alternative representation of the inductance equation.

To prove that the primary power E1I1 is equal to the negative secondary power -E2I2 in an ideal transformer, we start by considering the relationship between the primary and secondary emfs and currents.

The primary emfs (E1) is related to the secondary emf (E2) by the turns ratio of the transformer, denoted as a. Therefore, we can write E2 = aE1.

Similarly, the primary current (I1) is related to the secondary current (I2) by the inverse of the turn ratio, which can be written as I2 = (1/a)I1.

Now, let's consider the power in the primary and secondary circuits. The power in the primary circuit is given by P1 = E1I1, and the power in the secondary circuit is given by P2 = E2I2.

Substituting the expressions for E2 and I2, we have P2 = (aE1)(1/a)I1, which simplifies to P2 = E1I1.

Therefore, we can conclude that the primary power E1I1 is equal to the negative secondary power -E2I2.

Regarding the expression of inductance, given as L = NiΦ, where N is the number of turns and Φ is the magnetic flux, we can further simplify it.

We know that the magnetic flux Φ is related to the current I by the inductance L, i.e., Φ = LI. Substituting this into the previous expression, we have L = NLI.

Since L is a scalar quantity, we can express it as L = ℜN^2, where ℜ is a constant that depends on the physical properties of the transformer.

Therefore, the inductance L can be expressed as L = ℜN^2, which is an alternative representation of the inductance equation.
