Create your own Transportation Problem (with at least 4 demand and 3 supply units) and solve it with transportation alg. (use Vogel App. Method for starting solution)

Answers

Answer 1

To find the total transportation cost, the allocation cost for each cell is multiplied by the unit cost, and the sum is taken. The sum of these costs is $12,800.

Transportation Problem: A manufacturing firm has three warehouses supplying to four retail outlets. The following table shows the unit transportation costs (in $) from each warehouse to each outlet and the units of demand and supply at each location.

The transportation algorithm can be used to solve this problem with the Vogel approximation method being the starting solution. Below is the transportation table (in dollars):

|      | Retail Outlet 1 | Retail Outlet 2 | Retail Outlet 3 | Retail Outlet 4 | Supply |

Warehouse 1  |        6        |       5         |       3         |       7         |  300   |

Warehouse 2  |        9        |       7         |       4         |       6         |  200   |

Warehouse 3  |        2        |       8         |       5         |       9         |  250   |

Demand      |       200       |      150        |      100        |      200        |        |

The Vogel approximation method is an iterative procedure that selects the smallest difference between the two smallest costs for each row or column and then assigns the maximum possible allocation to it.

Step 1:

Subtract the smallest cost from the second-smallest cost and record the differences for each row and column. The difference is written in the same row or column as the subtracted number. The differences are calculated as follows:

|      | Retail Outlet 1 | Retail Outlet 2 | Retail Outlet 3 | Retail Outlet 4 | Supply |

Warehouse 1  |        6        |       5         |       3         |       7         |  300   |

Warehouse 2  |        9        |       7         |       4         |       6         |  200   |

Warehouse 3  |        2        |       8         |       5         |       9         |  250   |

Demand      |       200       |      150        |      100        |      200        |        |

The differences are as follows:

|      | Retail Outlet 1 | Retail Outlet 2 | Retail Outlet 3 | Retail Outlet 4 | Supply |

Warehouse 1  |        1        |       2         |       0         |       4         |  300   |

Warehouse 2  |        3        |       1         |       0         |       2         |  200   |

Warehouse 3  |        3        |       1         |       0         |       4         |  250   |

Demand      |       200       |      150        |      100        |      200        |        |

Step 2:

Identify the largest difference for each row or column and then select the smallest number in that row or column for the next allocation. The Vogel approximation method is used to determine the maximum allocation for that row or column. The total cost is then multiplied by the unit cost. The table below shows the maximum allocation and cost for each row or column.

The cost of transportation is shown below:

|        | Retail Outlet 1 | Retail Outlet 2 | Retail Outlet 3 | Retail Outlet 4 | Supply |

Warehouse 1   |        6        |       5         |       3         |       7         |  300   |

Warehouse 2  |        9        |       7         |       4         |       6         |  200   |

Warehouse 3  |        2        |       8         |       5         |       9         |  250   |

Demand          |       200       |      150        |      100        |      200        |        |

The final solution to the given transportation problem, with a minimum cost of 2050 units, is shown below:

D1 | D2 | D3 | D4 | S1 | 30 | 20 | 30 | 20 | S2 | 0 | 60 | 20 | 30 | S3 | 10 | 0 | 10 | 40 | Total Cost | 1800 | 600 | 650 | 2050 |

Explanation:

A transportation problem is one of the most fundamental optimization problems that exist. In this problem, goods are transported from various supply sources to various demand locations in the most efficient and cost-effective manner possible. When demand and supply quantities are known, transportation issues occur.

Let us now build a transportation problem with at least four demand and three supply units. We'll solve it using the transportation algorithm, and we'll use the Vogel App method to begin.

The problem is as follows:

Let us suppose that there are three factories (supply locations), S1, S2, and S3, and four warehouses (demand locations), D1, D2, D3, and D4. The supply amounts available at each factory and the requirements of each warehouse are shown below.

Supply (units) | Demand (units) | S1 | S2 | S3 | D1 | 60 | 30 | 40 | 50 | D2 | 30 | 70 | 20 | 30 | D3 | 40 | 20 | 10 | 40 | D4 | 20 | 60 | 30 | 10 |

To begin, let us generate the initial table below, which includes the amount of units available from each source to each destination.

Supply (units) | Demand (units) | S1 | S2 | S3 | Availability | D1 | 60 | 30 | 40 | 130 | D2 | 30 | 70 | 20 | 120 | D3 | 40 | 20 | 10 | 70 | D4 | 20 | 60 | 30 | 110 |

Requirement | 50 | 30 | 40 | 120 |

We'll begin by calculating the difference between the two smallest costs for each supply and demand row. Then we'll choose the row with the biggest difference as our starting point.

In this case, the differences for the supply rows are:

Supply (units) | Demand (units) | S1 | S2 | S3 | Availability | D1 | 60 | 30 | 40 | 130 | 20 | D2 | 30 | 70 | 20 | 120 | 30 | D3 | 40 | 20 | 10 | 70 | 10 | D4 | 20 | 60 | 30 | 110 | 20 |

Requirement | 50 | 30 | 40 | 120 |

Difference | 10 | 20 | 30 |  |

We'll choose the third row (supply from S3) as our starting point since it has the largest difference of 30. We'll provide as much as possible to the minimum cost cell (D2, S1), which is 20. We'll update the availability column and the demand row and cross out the cell.

D1 | D2 | D3 | D4 | S1 | 40 | 0 | 40 | 20 | S2 | 30 | 70 | 20 | 30 | S3 | 0 | 0 | 0 | 50 |

Availability | 20 | 50 | 10 | 90 |

Requirement | 50 | 10 | 40 | 120 |

We'll now update the differences based on the available cells (we only have two remaining).

Supply (units) | Demand (units) | S1 | S2 | S3 | Availability | D1 | 40 | 0 | 40 | 110 | 20 | D2 | 0 | 50 | 0 | 100 | 10 | D3 | 40 | 20 | 10 | 70 | 10 | D4 | 20 | 10 | 30 | 100 | 20 |

Requirement | 50 | 20 | 40 | 120 |

Difference | 10 | 40 | 20 |  |

The second row (supply from S2) has the largest difference, so we'll select it.

The minimum cost cell with the highest availability is (D2, S3), and we'll give it as much as possible (10).

D1 | D2 | D3 | D4 | S1 | 40 | 10 | 30 | 20 | S2 | 30 | 60 | 20 | 30 | S3 | 0 | 0 | 10 | 40 |

Availability | 20 | 40 | 0 | 80 |

Requirement | 50 | 30 | 40 | 120 |

We'll now update the differences based on the available cells (we only have one remaining).

Supply (units) | Demand (units) | S1 | S2 | S3 | Availability | D1 | 40 | 0 | 30 | 110 | 20 | D2 | 0 | 60 | 0 | 90 | 20 | D3 | 30 | 20 | 0 | 50 | 10 | D4 | 20 | 0 | 10 | 90 | 30 |

Requirement | 50 | 0 | 40 | 120 |

Difference | 10 | 10 | 10 |  |

There is only one available row left, so we'll select the first one and provide as much as possible to the minimum cost cell (D1, S2), which is 10.

We'll cross it out and update the availability and demand rows.

D1 | D2 | D3 | D4 | S1 | 30 | 20 | 30 | 20 | S2 | 30 | 50 | 20 | 30 | S3 | 0 | 0 | 10 | 40 |

Availability | 10 | 30 | 0 | 60 |

Requirement | 40 | 0 | 40 | 120 |

The final solution, with a minimum cost of 2050 units, is shown below:

D1 | D2 | D3 | D4 | S1 | 30 | 20 | 30 | 20 | S2 | 0 | 60 | 20 | 30 | S3 | 10 | 0 | 10 | 40 | Total Cost | 1800 | 600 | 650 | 2050 |

criteria is considered.

Answers

A code with distance 2t + 1 can correct t or fewer errors using the minimum distance decoding criteria.

When considering the minimum distance decoding criteria, a code with a minimum distance of 2t + 1 can correct t or fewer transmission errors.

The minimum distance of a code refers to the smallest number of bit flips or symbol errors needed to transform one valid codeword into another. In this case, the distance is 2t + 1, which means that any two valid codewords in the code will have a minimum Hamming distance of at least 2t + 1.

By choosing the minimum distance decoding criteria, the decoder can identify and correct up to t or fewer transmission errors. This is because if the received codeword differs from the transmitted codeword by t or fewer errors, it will still be closer to the intended codeword than any other codeword in the code.

Therefore, the decoder can successfully correct these errors and recover the original transmitted message.

Given that X₁, X₂, ..., Xₙ are iid according to a uniform continuous distribution over the open interval (0,0+1).

Now, we have to find a sufficient statistics for 8.Let T = ∑Xᵢ, then T ~ U(n*0,n).Thus, T is a sufficient statistic for θ.Hence, T is a sufficient statistics for 8.

Given that X₁, X₂, ..., Xₙ are iid according to a uniform continuous distribution over the open interval (0,0+1).

We have to find a minimally sufficient statistics for

Let Y = nX(n)/(1-X(n)), thenY = (nX(n))/(1-X(n)) = (nX(n))/(X(n)-X(1)) = 1/[(X(n)-X(1))/n].Now, 0 < X(1) ≤ X(n) < 1. Therefore, 0 < (X(n)-X(1))/n ≤ 1/n. Then, Y takes values in [0,∞).Thus, Y is a one-to-one function of T.

A cubic polynomial with a critical point at x=2, an inflection point at (1,4), and a leading coefficient of 1

Answers

If a critical point at x=2, an inflection point at (1,4), and a leading coefficient of 1, the final formula for the cubic polynomial is f(x) = x³ - 3x² + 12x - 6.

To find the formula for a cubic polynomial with specific properties, we can start by considering the critical point and the inflection point.

Given that the critical point is at x = 2, we know that the derivative of the cubic polynomial should be equal to zero at x = 2. This means that the slope of the polynomial at x = 2 is zero. Taking the derivative of the cubic polynomial, we have:

f'(x) = 3ax² + 2bx + c.

Setting this equal to zero and substituting x = 2, we get:

3a(2)² + 2b(2) + c = 0.

12a + 4b + c = 0.

Now, let's consider the inflection point at (1,4). We know that the second derivative of the cubic polynomial should be zero at x = 1. Taking the second derivative, we have:

f''(x) = 6ax + 2b.

Setting this equal to zero and substituting x = 1, we get:

6a(1) + 2b = 0.

6a + 2b = 0.

Solving the system of equations consisting of 12a + 4b + c = 0 and 6a + 2b = 0, we find a = -1/2, b = 3/2, and c = -6.

Therefore, the formula for the cubic polynomial is:

f(x) = -1/2x³ + 3/2x² - 6x + d.

The leading coefficient is 1, so we have:

f(x) = x³ - 3x² + 12x + d.

To determine the value of d, we can use the fact that the inflection point is (1,4). Substituting x = 1 and y = 4 into the equation, we get:

4 = 1 - 3 + 12 + d.

4 = 10 + d.

d = -6.

Therefore, the final formula for the cubic polynomial is:

f(x) = x³ - 3x² + 12x - 6.

A radiograph technician has a technique of 30 mAs and 120 kV at 100 cm SID with a 5:1 grid, and produces an intensity of 100 mR. If she wants to keep maintain exposure at: 200 cm, a 10:1 grid, with 138 kV , what should the new mAs be?

Answers

The new mAs should be approximately 45 mAs.
The intensity of radiation at a given distance can be calculated using the inverse square law:

Intensity2 = Intensity1 × (Distance1/Distance2)^2

Given:
Intensity1 = 100 mR
Distance1 = 100 cm
Distance2 = 200 cm

Using the above formula, we can calculate the new intensity at 200 cm:

Intensity2 = 100 mR × (100 cm/200 cm)^2
Intensity2 = 100 mR × (1/4)
Intensity2 = 25 mR

To maintain the same exposure at the new distance, the new mAs needs to be adjusted accordingly. We can use the exposure maintenance formula:

mAs2/mAs1 = (kVp2/kVp1) × (Distance1/Distance2)^2 × (Gridratio2/Gridratio1)^2

Given:
mAs1 = 30 mAs
kVp1 = 120 kV
kVp2 = 138 kV
Gridratio1 = 5:1
Gridratio2 = 10:1

Substituting the given values into the formula, we can solve for mAs2:

mAs2/30 mAs = (138 kV/120 kV) × (100 cm/200 cm)^2 × (10/5)^2
mAs2/30 mAs = (1.15) × (0.5)^2 × (4)
mAs2/30 mAs = 1.15 × 0.25 × 4
mAs2/30 mAs = 0.115

Simplifying, we find:
mAs2 = 30 mAs × 0.115
mAs2 ≈ 3.45 mAs

Therefore, the new mAs should be approximately 45 mAs (rounded to the nearest whole number) to maintain exposure at 200 cm with a 10:1 grid and 138 kV.

To maintain exposure at a new distance of 200 cm with a 10:1 grid and 138 kV, the radiograph technician should set the new mAs to approximately 45 mAs. This adjustment takes into account the changes in distance, kV, and grid ratio while ensuring that the radiation intensity remains consistent.

Answers

The statement is False.

(a) Let x be an integer. If 4x² + 3x + 7 is odd, then x must be even.Statement (a) is false.

Here is the explanation:We know that an integer is odd if and only if it can be represented in the form of 2k + 1, where k is any integer.Let us assume that x is an odd integer. Then, we can write x as 2k + 1, where k is any integer.Substituting the value of x in 4x² + 3x + 7, we get;4x² + 3x + 7 = 4(2k + 1)² + 3(2k + 1) + 7= 4(4k² + 4k + 1) + 6k + 3 + 7= 16k² + 16k + 4 + 6k + 10= 16k² + 22k + 14= 2(8k² + 11k + 7)which is an even integer as it is a multiple of 2.

Therefore, we have proven that if x is odd, then 4x² + 3x + 7 is even.So, we have disproved the statement as it is not true for all integers. It's only true for odd integers only. Therefore, statement (a) is false.

Step-by-step explanation:

write an equation that states (x,y) is the same distance from (4,1) as it is from the x-axis.

Answers

The equation that states (x, y) is equidistant from (4, 1) and the x-axis is -8x - 2y + 17 = 0.

To express that the point (x, y) is equidistant from both the point (4, 1) and the x-axis, we can set up an equation using the distance formula.

The distance formula states that the distance between two points (x₁, y₁) and (x₂, y₂) is given by:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

In this case, we want the distance from (x, y) to (4, 1) to be equal to the distance from (x, y) to the x-axis. The x-axis can be represented by the equation y = 0.

Let's set up the equation:

√((x - 4)² + (y - 1)²) = √((x - x)² + (y - 0)²)

Simplifying, we get:

√((x - 4)² + (y - 1)²) = √(x² + y²)

To remove the square roots, we can square both sides of the equation:

((x - 4)² + (y - 1)²) = (x² + y²)

Expanding and simplifying further, we have:

x² - 8x + 16 + y² - 2y + 1 = x² + y²

Combining like terms, we obtain:

-8x - 2y + 17 = 0

Therefore, the equation that states (x, y) is equidistant from (4, 1) and the x-axis is -8x - 2y + 17 = 0.

All of these seats must be filled by members of GKSMA, of which there are 50. No member may hold more than 1 position. How many different ways are there to fill the positions

Answers

Answer:

Number of different ways of filling the position is   8961115245946500

Step-by-step explanation:

There are total of 4 positions which can be arranged in 4! Ways  

Like wise there are 12 positions. Hence the number of arrangements for these 12 positions would be 12!

Overall there are 12+4 = 16 positions in which 50 people needs to be arranged

Number of different ways of filling the position is  

50P16 /(12! *4!)

= 8961115245946500

The number of different ways of filling the position is,  8961115245946500

There are total of 4 positions can be arranged in 4! Ways  

Similarly  there are 12 positions.

Therefore, the number of arrangements for these 12 positions is  12!

When we use the permutation?

If there is an arrangement of the data then we use the permutation

Therefore we can say that there are 12+4 = 16 positions in which 50 people needs to be arranged.

The number of different ways of filling the position is,

[tex]50P16 /(12! *4!)[/tex]

By using the calculater you can find,

= 8961115245946500

The area of the carpet is 48x^2y+16xy^2, if the width is 8xy inches, what is the length of the carpet?

Answers

Answer:

Step-by-step explanation:

(48x^2)(y) + (16x)(y^2).

This is addition, so the distributive property applies. [(48x^2)(y) + (16x)(y^2)]/8xy = (48x^2)(y)/8xy+(16x)(y^2)/8xy = 6x+2y.

Division rules are explained below.

I included the parentheses to emphasize the difference between x^2y, which means x to the 2y, and (x^2)(y), which is x^2 times y.

48/8 = 6x^2 times y divided by 8xy equals x because x^2/x = x^(2-1), because x=x^1,  and so, equals x; The same y^2/y. The other 2 y's and 2 x's cancel.

Find a*b. a = (4, 1, 1/5), b = (6,-4, -15)

Answers

The calculated product of the vectors a and b is 17

How to calculate the product of the vectors

From the question, we have the following parameters that can be used in our computation:

a = (4, 1, 1/5) and b = (6,-4, -15)

The product of the vectors can be calculated using

a * b = Sum of products of each position

Using the above as a guide, we have the following:

a * b = 4 * 6 + 1 * -4 + 1/5 * -15

Evaluate the expression

a * b = 17

Hence, the product of the vectors a and b is 17

Mrs. Bruce wants to put in a swimming pool with a deck around the perimeter of the pool. The pool will be rectangular shaped and will have dimensions of 12 feet by 20 feet. The deck around the perimeter will be uniformed in width and have a total area of 68 square feet. Find the width of the deck.

Hint: Draw and accurately label a sketch of the deck and pool in the space below.

Answers

Answer:

I think! 3.5 feet wide

Step-by-step explanation:

the area of the pool is 240 square feet. divide by 68 square feet gives you 3.539= 3.5 feet wide. dont shoot me if I'm wrong lol

The width of the deck is approximately 2.65 feet.


How to calculate the width?

To solve the problem, we need to first find the total area of the pool and deck combined, and then subtract the area of the pool to find the area of the deck.

The total area of the pool and deck can be represented as follows:

(12 + 2x) x (20 + 2x)

where x is the width of the deck.

The area of the pool is:

12 x 20 = 240

So, the area of the deck can be found by subtracting the area of the pool from the total area:

(12 + 2x) x  (20 + 2x) - 240 = 68

Expanding the left side and simplifying, we get:

4x²+ 64x - 208 = 0

Dividing both sides by 4, we get:

x²+ 16x - 52 = 0

Using the quadratic formula, we get:

x = (-b ± √(b² - 4ac)) / 2a

Where a = 1, b = 16, and c = -52.

Plugging in these values, we get:

x = (-16 ± √(16² - 4(1)(-52))) / 2(1)

x = (-16 ± √(960)) / 2

x = (-16 ± 4√(15)) / 2

x = -8 ± 2√(15)

Since the width of the deck cannot be negative, we can discard the negative solution, and we are left with:

x = -8 + 2√(15)

So, the width of the deck is approximately 2.65 feet.
