Simplex Method Quiz

What is the primary goal of the simplex method?

• To find the minimum value of a function

• To solve quadratic equations

• To calculate the average of a dataset

• To find the maximum value of a function

What is the first step in using the pivot for elimination?

• Add the pivot to all other entries

• Change all entries in the pivot row to zero

• Change all entries in the pivot column to zero except the pivot

• Multiply the pivot by zero

How do you determine if further pivoting is needed?

• If all indicators are negative

• If all indicators are non-negative

• If there is at least one negative indicator

• If there is at least one positive indicator

What is the next step after identifying a negative indicator?

• Add the row to itself

• Multiply the row by zero

• Find a new pivot

• Stop the process

How is the new pivot chosen?

• By selecting the largest number in the column

• By selecting the smallest number in the column

• By selecting the largest positive ratio of equal column entry to pivot column entry

• By selecting the smallest positive ratio of equal column entry to pivot column entry

What indicates that the pivoting process is complete?

• All indicators are non-negative

• All entries in the pivot column are zero

• All entries in the pivot row are zero

• All indicators are negative

What defines a basic variable in the simplex table?

• A column with all zeros except for one entry

• A column with all ones

• A column with all zeros

• A column with all non-zero entries

What is the value of a non-basic variable in the solution?

• It is always 1

• It is always 0

• It is always equal to the indicator

• It is always equal to the pivot

What does a slack variable value of zero indicate?

• All resources were used

• Some resources were left unused

• The maximum value is negative

• The solution is incorrect

What is the maximum value of Z in the given problem?

• 12

• 0

• 360

• 420
