Note that we just used the word “typical” although in many cases you might think of using the word “average.” We need to be careful with the word “average” as it means different things to different people in different contexts. One of the most common uses of the word “average” is what mathematicians and statisticians call the arithmetic mean, or just plain old mean for short.

Suppose we are hired by a politician to determine the amount of support he has among the electorate. What population should we study? How do we choose an appropriate sample? There are many ways to sample a population, but there is one goal we need to keep in mind: we would like the sample to be representative of the population.

In a standard bank account, any interest we earn is automatically added to our balance, and we earn interest on that interest in future years. This reinvestment of interest is called compounding.

Si queremos estudiar la cantidad de dinero que un estudiante universitario típico de primer año gasta en libros de texto, nuestra población podría ser todos estudiantes de primer año en tu universidad. Una muestra es un subconjunto más pequeño de toda la población, idealmente uno que sea bastante representativo de toda la población. Se discuten los métodos de muestreo con mayor detalle

For example, any time you say “walk along this line” or “watch out, this road quickly angles to the left”, you are using geometric terms to make sense of the environment around you. In the world of mathematics, each of these geometric terms has a specific definition. It is important to know these definitions—as well as how different figures are constructed—to become familiar with the language of geometry.

After this chapter, we solve quadratic equations by using any of the techniques we have discussed in this textbook.

If the rate of the passenger train exceeds the rate of the freight train by 15 miles per hour, and they meet after 4 hours, what are the rates of the passenger and train?
