PLEASE SOLVE THE 4 MULTIPLE CHOICE PROBLEMS

How does the tabular form of simplex differ from the algebraic form?

a) Tabular form compactly displays the systems of equations related to the problem but algebraic form outlines the systems of equations.

b) Tabular form use minimum ratio test to find solutions to the systems of equations related to the problem but algebraic form uses pivot rows and pivot numbers to find solution to the systems of equations

c) Tabular form uses the original model of the systems of equations related to the problem but algebraic form uses the augmented model of the systems of equations.

d) Tabular form saves writing of the symbols for the variables in the systems of equations related to the problem but algebraic form permits highlighting the numbers involved in solving the systems of equations.

How is the augmented form of a problem obtained when solving a problem using the matrix form.

a) By introducing a column vector of the slack variables.

b) By introducing a row vector of the slack variables.

c) By introducing a null vector of the slack variables.

d) By introducing an identity vector of the slack variables.

For the Wyndor Glass problem why are the slack variables not shown in the objective function of the algebraic form?

a) the slack variables are not required in the objective function

b) the slack variables coefficients are zeros and thus not considered

c) the slack variables are never required in the augmented form of any problem.

d) the slack variables are not required when using the algebraic form

The slack variables for the Wyndor Glass company problem represent

a) unused production time in each plant.

b) the extra production rate in each plant

c) the extra projected profit from each plant.

d) the number of additional windows and doors from each plant.
