Catalog Course Description

For students pursuing a liberal arts curriculum or a program without a specified mathematics requirement. Topics include linear and exponential growth; statistics; personal finance; and geometry, including scale and symmetry. Emphasizes techniques of problem-solving and application of modern mathematics to understanding quantitative information in the everyday world.

### Goals, Topics, and Objectives

Goal Statement
1. To generate an appreciation of the quantitative tools that help to present and explain issues arising in the media and students' daily lives.
2. To heighten communication skills, both written and oral, of mathematical ideas so that students can express quantitative evidence in support of an argument or purpose of a work.
3. To increase the ability to explain information presented in mathematical forms such as equations, graphs, diagrams, tables, and paragraphs and to convert relevant information between the forms.
4. To strengthen the ability to make judgments and draw appropriate conclusions based on the quantitative analysis of data, while recognizing the limits of this analysis.
5. To enhance mathematical competence in performing appropriate calculations and communicating results in the specific areas of modeling, personal finance, basic statistics, and geometry.
Core Course Topics
1. Linear and Exponential Change
1. Recognize linear functions.
2. Find the slope of a linear function or model.
3. Interpret the slope of a linear function or model.
4. Find trend lines.
5. Interpret trend lines.
6. Find an exponential formula modeling data or a percentage-growth situation.
7. Solve problems involving exponential functions, such as growth, decay, doubling time, and half-life.
8. Describe how exponential and logarithmic functions are related.
9. Solve problems involving logarithms, such as sound volume and earthquake magnitude.
2. Personal Finance
1. Calculate simple and compound interest.
2. Solve problems about Annual Percentage Rate and Annual Percentage Yield.
3. Use formulas and amortization tables to solve problems about loans.
4. Use tables and formulas to solve problems about savings and annuities.
5. Calculate the interest paid on a credit card transaction.
3. Basic Statistics
1. Calculate mean, median, and mode, and choose the most representative number from among these.
2. Classify a data value as an outlier.
3. Calculate a five-number summary and use it to construct a box plot.
4. Calculate the standard deviation for a data set.
5. Interpret the standard deviation for a data set.
6. Construct a histogram.
7. Determine whether data are distributed normally.
8. Apply properties of the normal distribution, including calculating z-scores.
9. Calculate percentiles.
10. Interpret percentiles.
11. Apply the Central Limit Theorem.
12. Apply the terms "margin of error," "confidence interval," and "confidence level."
13. Calculate the sample size necessary for a particular confidence level.
14. Determine whether results are statistically significant.
15. Describe correlation and distinguish it from causation.
4. Geometry
1. Calculate perimeters and areas of plane figures.
2. Solve problems involving the Pythagorean Theorem.
3. Calculate surface areas and volumes of three-dimensional figures.
4. Apply properties of proportionality to similar figures.
5. Recognize rotational symmetry and reflectional symmetry.
6. Apply properties of rotational symmetry and reflectional symmetry.

### Assessment and Requirements

• All students will be required to complete a comprehensive final examination that assesses the learning of all course objectives. This exam must be weighted in a manner so that this exam score is worth a minimum of fifteen percent (15%) of the final course grade.
• Additional assessment of student achievement may include assignments, quizzes, and exams.
• Application problems must not only be included on chapter exams but also on the final exam.
General Course Requirements and Recommendations
• A scientific calculator is required of each student.
• Application problems must be covered in all mathematics courses. Every section of any course outline that includes application problems must be covered.
