Suppose that the waiting time for a pizza to be ready at a local pizzeria has been found to be normally distributed with a mean of 20 minutes and a standard deviation of 8 minutes. Suppose that in an effort to provide better service to the customers, the manager has decided to provide discounts to those individuals whose waiting time exceeds a predetermined time. The manager decides that 10% of the customers should receive this discount. What is the number of minutes they need to wait to receive the discount

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
