4. Making and Interpreting Data Displays
Using an appropriate display to show the distribution of a set of numerical data helps make the information presented meaningful to the viewer. Three different displays are presented below with their uses. Stem and Leaf Plots A stem and leaf … Continue reading
3. Sampling and Analyzing Sets of Data
There are a lot of definitions in sampling methods. Read the descriptions below and think about situations in the real world that you see these sampling methods. 1. In a random sample, every member of the population has an equal chance … Continue reading
2. Combinations and Permutations
A permutation is an arrangement of objects where order is important. For example, the 6 possible permutations of the letters A, B, and C are: ABC ACB … Continue reading
1. Finding Probabilities of Simple and Compound Events
First, some important probability terminology. A possible result of an experiment is an outcome. For instance, when you toss a die, there are six possible outcomes, 1, 2, 3, 4, 5, or 6. An event is an outcome or collection … Continue reading
3. Performing Operations with Rational Expressions and Functions
Rational Expressions Performing operations on rational expressions is similar to performing operations on numerical fractions. Any common factors in the numerator and denominator should be divided out, and the original expression should be used when finding excluded values. The following … Continue reading
2. Graphing Rational Functions
As we saw in the previous section, the graphs of inverse variations are hyperbolas. Hyperbolas have their own special traits just like parabolas and can be sketched using the same processes. The graphs of the parent function: and the generic … Continue reading
1. Modeling Direct and Inverse Variation with Rational Functions
Direct and inverse variation are two common relationships in mathematics that can be seen easily graphically. When thinking of direct variation you want to think of things that grow or shrink concurrently. For example, the number of cars in a … Continue reading
