10. In Dec. 2012, The average price of a gallon of gasoline in the US was $3.31. Of this amount,225 cents was the cost of Crude oil, 26 cents the cost of refining, 36 cents the cost of distribution and marketing, and 44 cents the amount of tax. Use a pie graph to resent this data. 11. The life expectancy (in hours) of a fluorescent tube is normally distributed with mean 7000 and standard deviation 1000. Find the probability that a tube lasts for more than 8900 hours. 10. In Dec. 2012, The average price of a gallon of gasoline in the US was $3.31.
