Quantitative methods :Multiple choice questions
I have completed the answers to the questions. I just need to have someone confirm that they are correct. Thank you!
Indicate whether the sentence or statement is true or false.
F 1. Management science is the application of a scientific approach to solving management problems in order to help managers make decisions faster.
T 2. A model is a functional relationship including variables, parameters, and equations.
F 3. Management science techniques focus primarily on 3 specific steps of the management science process (observation, model construction and implementation) to find an appropriate solution to a problem.
F 4. Total cost equal the fixed cost plus the variable cost per unit divided by volume.
T 5. A model is a functional relationship including variables, parameters, and equations.
Identify the letter of the choice that best completes the statement or answers the question.

D 9. Which of the following statements is false?
a. common sense is one test of the validity of a model.
b. one way to validate a model is to predict history.
c. models are usually built sequentially rather than iteratively.
