Data collected at an airport suggests that an exponential distribution with mean value 2.475 hours is a good model for rainfall duration. (a) What is the probability that the duration of a particular rainfall event at this location is at least 2 hours? At most 3 hours? Between 2 and 3 hours? (Round your answers to four decimal places.) at least 2 hours at most 3 hours between 2 and 3 hours (b) What is the probability that rainfall duration exceeds the mean value by more than 4 standard deviations? (Round your answer to four decimal places.) What is the probability that it is less than the mean value by more than one standard deviation?

Cheryl bicycles 12 mph with no wind. Against the wind, she bikes 8 miles in the same time that it takes to bike 14 miles with the wind. What is the speed of the wind? Fill in the table to translate the information from this problem if w represents the speed of the wind. Be sure to use parentheses appropriately, if needed in the expression and do not use any spaces.
