Description
Features stepbystep examples based on actual data and connects fundamental mathematical modeling skills and decision making concepts to everyday applicability
Featuring key linear programming, matrix, and probability concepts, Finite Mathematics: Models and Applications emphasizes crossdisciplinary applications that relate mathematics to everyday life. The book provides a unique combination of practical mathematical applications to illustrate the wide use of mathematics in fields ranging from business, economics, finance, management, operations research, and the life and social sciences.
In order to emphasize the main concepts of each chapter, Finite Mathematics: Models and Applications features plentiful pedagogical elements throughout such as special exercises, end notes, hints, select solutions, biographies of key mathematicians, boxed key principles, a glossary of important terms and topics, and an overview of use of technology. The book encourages the modeling of linear programs and their solutions and uses common computer software programs such as LINDO. In addition to extensive chapters on probability and statistics, principles and applications of matrices are included as well as topics for enrichment such as the Monte Carlo method, game theory, kinship matrices, and dynamic programming.
Supplemented with online instructional support materials, the book features coverage including:
 Algebra Skills
 Mathematics of Finance
 Matrix Algebra
 Geometric Solutions
 Simplex Methods
 Application Models
 Set and Probability Relationships
 Random Variables and Probability Distributions
 Markov Chains
 Mathematical Statistics
 Enrichment in Finite Mathematics
