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.

1. pg 287 Finger length and gender Is there a relationship between gender and relative finger length? To find out, we randomly selected 452 U.S. high school students who completed a survey. The two-way table summarizes the relationship between gender and which finger was longer on the left hand (index finger or ring finger). Longer finger Index finger Ring finger Same length Total Gender Female 78 82 52 212 Male 45 152 43 240 Total 123 234 95 452 Suppose we randomly select one of the survey respondents. Define events R: ring finger longer and F: female. (a) Find P(R | F). Interpret this value in context. (b) Given that the chosen student does not have a longer ring finger, what's the probability that this person is male? Write your answer as a probability statement using correct symbols for the events.
