Concept explainers
a)
To demonstrate: A matrix multiplication for a A(3×4) and .B(4×1) matrix.
Non-linear programming (NLP):
Non-linear programming (NLP) is used in complex optimization problems where the objectives or constraints or sometimes both are non-linear functions of the decision variables. A model can be termed as non-linear for more than one reason.
b)
To demonstrate: A matrix multiplication for a A(1×4) and .B(4×1) matrix.
c)
To demonstrate: A matrix multiplication for a A(4×1) and .B(1×4) matrix.
d)
To demonstrate: A matrix multiplication for a A(1×4) and .B(1×4) matrix.
e)
To demonstrate: A matrix multiplication for a A(1×4), A(4×4), and .B(4×1) matrix.
f)
To demonstrate: A matrix multiplication for a A(3×3) , B(3×3), and B(3×1) matrix.
g)
To demonstrate: A matrix multiplication for an A(4×3) transpose and .B(4×3) matrix.

- Which of the following numbers is the smallest? sin((\pi )/(3)) sin((\pi )/(6)) sin(\pi ) sin((\pi )/(4)) sin((\pi )/(2)).arrow_forwardIf a convex function is multiplied by a negative constant, the result: A. is concave B. could be either convex or concave, depending on the value of the constant C. is convex D. is lineararrow_forwardM is any large numberarrow_forward
- Which of the following statements is correct regarding the EMH form? Select one: None of the answers are correct If the market is weak-form efficient, then it is also semistrong and strong-form efficient. If the market is semistrong form efficient, then it is also strong form efficient If a market is strong-form efficient, it is also semistrong and weak form efficient If the market is strong-form efficient, it is also semistrong but not weak-form efficientarrow_forwardOne player is assigned the number 10 and another player is assigned the number 5. It is an example ofarrow_forwardTRUE OR FALSE In Simplex Method, the pivot element should be changed to 1 in the formulation of the next table.arrow_forward
- There are 2657 professors in a college out of which one ofthem has to be selected for promotion through a game.Everyone will sit in a circle with numbered chairs. Each ofthem will evict the professor to his left, starting from the firstchair, and this cycle will go on until one last professor is left.Now you are one of the professors, which chair would youpick to ensure you get promoted?arrow_forward1+1 is equal to?arrow_forwardA business model is not particularly useful in managing a business and making decisions because it does not capture complex relationships. Select one: True Falsearrow_forward
- 3. Write the value produced by each expression below. Variables a, b, c, d, and e are unsigned integers with values 0, 1, 15, 5, and 20 respectively. Remind that in C++ zero is interpreted as false and anything non-zero is interpreted as true. (a) ! a || ! b (a) (b) (!b && !!c) || (d == e) || (!a && ((d + e) % 10 0)) =3= (b)arrow_forwardBad simulations Explain why each of the followingsimulations fails to model the real situation properly:a) Use a random integer from 0 through 9 to representthe number of heads when 9 coins are tossed. b) A basketball player takes a foul shot. Look at a ran-dom digit, using an odd digit to represent a good shot and an even digit to represent a miss.c) Use random numbers from 1 through 13 to represent thedenominations of the cards in a five-card poker hand.arrow_forwardAt Quickie Car Wash, the wash process is advertised to take less than 7 minutes. Consequently, management has set a target average of 390 seconds for the wash process. Suppose the average range for a sample of 10 cars is 8 seconds. Use the accompanying table to establish control limits for sample means and ranges for the car wash process.
