21. Which of the following statements are true?
a. A fairly recent alternative to algebraic modeling is spreadsheet modeling. Instead of relating various quantities with
algebraic equations and inequalities, we relate them in a spreadsheet with cell formulas.
b. Data are usually meaningless until they are analyzed for trends, patterns, relationships, and other useful
information
c. Algebraic models, by means of algebraic equations and inequalities, specify a set of relationships in a very precise
way. Their main drawback is that they require an ability to work with abstract mathematical symbols.
d. When we make inferences from data and search for relationships in data, or when we use decision trees to help
make decisions, we must deal with uncertainty.
e. All of these statements are true.
