Exercice 7: 1. Each morning a student arrives at his or her bus stop. The passing time for a bus is uniformly distributed between 8:00 a.m and 8:30 am. (a) What is the probability that the bus will pass between 8:10 a.m and 8:15 a.m. on a given day? (b) If this student has been waiting for the bus for 10 minutes, what is the probability that he or she has less than 8 minutes to wait? 2.

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.
