8)- In a Technometrics, May 1985 article, Vardeman and Ray suggest that the number of industrial accidents can be modeled by an exponential distribution. Suppose the number of accidents per hour at an industrial plant is exponentially distributed with mean u = 0.5. 1. What is the probability that at least one accident will occur in a randomly selected hour at the industrial plant? 2. What is the probability that less than two accidents will occur in a randomly selected hour at the industrial plant?

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.
