This problem is an example of a balanced transportation problem since the total supply of goods is equal to the total demand.

The transportation problem is a well-known linear programming problem in which commodities are shipped from sources to destinations at the minimum possible cost. The initial step in formulating a mathematical model for the transportation problem is to identify the sources, destinations, and the quantities transported.
The objective of the transportation problem is to minimize the total cost of transporting the goods. The mathematical model of the transportation problem is:
Let there be m sources (i = 1, 2, …, m) and n destinations (j = 1, 2, …, n). Let xij be the amount of goods transported from the i-th source to the j-th destination. cij represents the cost of transporting the goods from the i-th source to the j-th destination.
The transportation problem can then be formulated as follows:
Minimize Z = ∑∑cijxij
Subject to the constraints:
∑xij = si, i = 1, 2, …, m
∑xij = dj, j = 1, 2, …, n
xij ≥ 0
where si and dj are the supply and demand of goods at the i-th source and the j-th destination respectively.
Using the given table, we can formulate the transportation problem as follows:
Let A1, A2, and A3 be the sources, and B2, B3, and B4 be the destinations. Let xij be the amount of goods transported from the i-th source to the j-th destination. cij represents the cost of transporting the goods from the i-th source to the j-th destination.
Minimize Z = 27x11 + 27x12 + 32x13 + 15x21 + 21x22 + 20x23 + 16x31 + 22x32 + 18x33
Subject to the constraints:
x11 + x12 + x13 = 3
x21 + x22 + x23 = 14
x31 + x32 + x33 = 10
x11 + x21 + x31 = 21
x12 + x22 + x32 = 32
x13 + x23 + x33 = 26
xij ≥ 0
In this way, we can construct a mathematical model of the transportation problem using the given table. The model can be solved using the simplex method to obtain the optimal solution.

Step-by-step explanation:

 The system of equations does not have one solution because the lines will never intersect.

Based on the calculation, it appears that Matti had approximately 94 bottles of 0.5 litres and 11 bottles of 0.7 litres in the last patch of moonshine that he sold.

To solve the problem using the determinant method (Cramer's rule), we need to set up a system of equations based on the given information and then solve for the unknowns, which represent the number of 0.5 litre bottles and 0.7 litre bottles.

Let's denote the number of 0.5 litre bottles as x and the number of 0.7 litre bottles as y.

From the given information, we can set up the following equations:

Equation 1: 0.5x + 0.7y = 16.5 (total volume of moonshine)

Equation 2: 8x + 10y = 246 (total earnings from selling moonshine)

We now have a system of linear equations. To solve it using Cramer's rule, we'll find the determinants of various matrices.

Let's calculate the determinants:

D = determinant of the coefficient matrix

Dx = determinant of the matrix obtained by replacing the x column with the constants

Dy = determinant of the matrix obtained by replacing the y column with the constants

Using Cramer's rule, we can find the values of x and y:

x = Dx / D

y = Dy / D

Now, let's calculate the determinants:

D = (0.5)(10) - (0.7)(8) = -1.6

Dx = (16.5)(10) - (0.7)(246) = 150

Dy = (0.5)(246) - (16.5)(8) = -18

Finally, we can calculate the values of x and y:

x = Dx / D = 150 / (-1.6) = -93.75

y = Dy / D = -18 / (-1.6) = 11.25

However, it doesn't make sense to have negative quantities of bottles. So, we can round the values of x and y to the nearest whole number:

x ≈ -94 (rounded to -94)

y ≈ 11 (rounded to 11)

Therefore, based on the calculation, it appears that Matti had approximately 94 bottles of 0.5 litres and 11 bottles of 0.7 litres in the last patch of moonshine that he sold.

Question

Matti is making moonshine in the woods behind his house. He’s selling the moonshine in two different sized bottles: 0.5 litres and 0.7 litres. The price he asks for a 0.5 litre bottle is 8€, for a 0.7 litre bottle 10€. The last patch of moonshine was 16.5 litres, all of which Matti sold. By doing that, he earned 246 euros. How many 0.5 litre bottles and how many 0.7 litre bottles were there? Solve the problem by using the determinant method (a.k.a. Cramer’s rule).

Answer:

A. length = 23 cm; width = 5 cm

Step-by-step explanation:

So if 4 times the width would be \(4w\) and 3 more than would be \( + 3\), the equation would be \(l = 4w + 3\). If the perimeter is 56, then the new equation, \(2(4w + 3) + 2(w) = 56\) can be formed. This simplifies to \(8w + 6 + 2w = 56\), then to \(10w + 6 = 56\), then to \(10w = 50\), and finally, \(w = 5\). So the width is 5, and now plug it into the first equation.

\(l = 4(5) + 3\), becomes \(l = 20 + 3\), becomes \(l = 23\).

So the dimensions are: length = 23 cm, width = 5 cm.

*And just to be sure, \(2(23 + 5) = 2(28) = 56\) which is correct.

The team swam at a speed of 20 centimeters per second during their warm up.

First, let's convert the length of one lap from meters to centimeters:

5 meters = 500 centimeters

So, the team swam 12 laps of 500 centimeters each, for a total distance of:

12 laps × 500 centimeters/lap = 6000 centimeters

Next, let's convert the time from minutes to seconds:

5 minutes = 300 seconds

To find the speed in centimeters per second, we can divide the distance by the time:

speed = distance ÷ time = 6000 centimeters ÷ 300 seconds

simplifying, we get:

speed = 20 centimeters/second

Therefore, the team swam at a speed of 20 centimeters per second during their warm up.

Step-by-step explanation:

To find the extremum of the function f(x,y) = 2y^2-9x^2 subject to the constraint 3xy = 27x, we can use the method of Lagrange multipliers.

Let g(x,y) = 3xy - 27x be the constraint function. We want to find the critical points of the function f(x,y) subject to the constraint g(x,y) = 0, so we set up the following system of equations:

∇f(x,y) = λ∇g(x,y)

g(x,y) = 0

where λ is the Lagrange multiplier.

Taking the partial derivatives of f(x,y) with respect to x and y, we get:

∂f/∂x = -18x

∂f/∂y = 4y

Taking the partial derivatives of g(x,y) with respect to x and y, we get:

∂g/∂x = 3y - 27

∂g/∂y = 3x

Setting ∇f(x,y) = λ∇g(x,y), we get the following system of equations:

-18x = λ(3y - 27)

4y = λ(3x)

Multiplying the first equation by 4 and the second equation by -6, we get:

-72x = λ(12y - 108)

-24y = λ(-18x)

Simplifying these equations, we get:

4x = λ(y - 9)

y = 3λx/2

Substituting y = 3λx/2 into the first equation, we get:

4x = λ(3λx/2 - 9)

8x = λ^2x - 18λ

x(λ^2 - 8) = 18λ

If x = 0, then y = 0, which is not a critical point since f(0,0) = 0. Therefore, we can divide both sides by x to get:

λ^2 - 8 = 18/ x

If λ^2 - 8 < 0, then there are no critical points since the equation above has no real solutions. Therefore, we assume λ^2 - 8 ≥ 0, which gives:

λ = ±√(8 + 18/x)

Substituting λ into y = 3λx/2, we get:

y = ±√(2x(8 + 18/x))/2

We want to find the extremum of f(x,y) = 2y^2-9x^2, so we evaluate this function at the critical points:

f(x,y) = 2y^2-9x^2 = 2(2x(8 + 18/x))/4 - 9x^2 = (4x^2 + 36) / x - 9x^2

Taking the derivative of f(x,y) with respect to x, we get:

f'(x,y) = (8x - 36)/x^2 - 18

Setting f'(x,y) = 0, we get:

8x - 36 = 18x^2

18x^2 - 8x + 36 = 0

Solving for x, we get:

x = (2 ± √13)/9

Substituting x into y = ±√(2x(8 + 18/x))/2, we get:

y = ±(4 ± √13)√2/3

Therefore, the critical points are (x,y) = x = (2 ± √13)/9, y = ±(4 ± √13)√2/3

A. The marginal utility of consumption (MUc) of increasing consumption from c=4 to c=5 is 10.

B. The marginal utility of consumption (MUc) of increasing consumption from c=5 to c=6 is 12.

The utility function given is u(c,l) = c² + l², where c represents consumption and l represents leisure. To find the marginal utility of consumption (MUc), we need to take the derivative of the utility function with respect to c.

Taking the derivative of u(c,l) with respect to c, we get:

∂u/∂c = 2c

A. To find the MUc of increasing consumption from c=4 to c=5, we substitute c=4 into the derivative:

MUc = 2(4) = 8

B. To find the MUc of increasing consumption from c=5 to c=6, we substitute c=5 into the derivative:

MUc = 2(5) = 10

Therefore, the MUc of increasing consumption from c=4 to c=5 is 8, and the MUc of increasing consumption from c=5 to c=6 is 10.

The concept of utility function is fundamental in economics and represents an individual's preferences over different combinations of goods and services. Marginal utility measures the change in satisfaction or utility resulting from a one-unit increase in the consumption of a particular good or service, holding other factors constant. It helps in understanding how consumers make choices based on their preferences and the additional satisfaction they derive from consuming more of a particular good or service.

Based on the given information, the counselor obtained a t-score of -0.20. To make a decision regarding the null hypothesis, we need to compare this t-score to a critical value or determine the p-value associated with it.

If the counselor has a predetermined significance level (α), she can compare the t-score to the critical value from the t-distribution table. If the t-score falls within the critical region (beyond the critical value), she would reject the null hypothesis. However, without knowing the significance level or degrees of freedom, we cannot make a definitive decision based solely on the t-score.

Alternatively, if the counselor has access to the p-value associated with the t-score, she can compare it to the significance level. If the p-value is less than the significance level (typically α = 0.05), she would reject the null hypothesis.

The statement ''the mean return and the standard deviation of returns can be used to describe the distribution of stock.'' is true because the mean return and standard deviation of returns are important statistical measures that describe the distribution of stock, providing information about its average performance and volatility respectively.

The mean return represents the average rate of return over a given period, providing an indication of the stock's profitability. It gives investors an idea of the stock's long-term performance and helps in comparing different stocks or investment options.

The standard deviation of returns, on the other hand, measures the volatility or variability of the stock's returns around the mean. A higher standard deviation indicates greater price fluctuations and a riskier investment, while a lower standard deviation suggests more stable returns.

Together, the mean return and standard deviation provide valuable insights into the distribution of stock returns. They help investors assess the expected return and risk associated with a particular stock, aiding in investment decision-making and portfolio management strategies.

The volume of each soup can is approximately 785.4 cubic centimeters.

The volume of a cylinder can be calculated using the formula:

Volume =\(\pi\) ×\(radius^2\)× height

where π (pi) is a mathematical constant approximately equal to 3.14159, the radius is the distance from the center of the circular base of the cylinder to its edge, and height is the vertical distance between the circular bases.

In other words, the volume of a cylinder is the amount of space occupied by the cylinder, and it depends on the size of the circular base and the height of the cylinder.

In this case, the radius of the can is given as centimeters and the height is also given as centimeters. So, we can substitute these values in the formula and calculate the volume:

Volume = π × \(radius^2\) × height

Volume = π ×\(5^2\) × 10

Substituting radius = 5 cm and height = 10 cm

Volume = 250π cubic centimeters

Volume ≈ 785.4 cubic centimeters (rounded to one decimal place)
