A manager at a company that manufactures cell phones has noticed that the number of faulty cell phones in a production run of cell phones is usually small and that the quality of one day's run seems bearing on the next day. a) What model might you use to model the number of faulty cell phones produced in one day? b) If the mean number of faulty cell phones is 1.3 per day, what is the probability that no faulty cell phones will be produced tomorrow? c) If the mean number of faulty cell phones is 1.3 per day, what is the probability that 3 or more faulty cell phones were produced in today's run? have no a) Which model might you use? Uniform O Poisson O Binomial Geometric b) The probability that no faulty cell phones will be produced tomorrow is- (Round to four decimal places as needed.) c) The probability that 3 or more faulty cell phones were produced in today's run is. (Round to four decimal places as needed.)

Rate of Change
The relation between two quantities which displays how much greater one quantity is than another is called ratio.
Slope
The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:
