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.
