Zipf’s Law. According to Zipf’s Law, the numberof cities N with a population greater than S is inversely proportional to S. In 2012, there were 285U.S. cities with a population greater than 100,000.Estimate the number of U.S. cities with a populationbetween 350,000 and 500,000; between 300,000 and600,000.
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
