Explanation Given Information: Cargo traffic between the United States cities are 975 by rail, 866 by road, 8.7 by air, 435 by inland water and 587 by pipeline. Graph: Consider the provided data: rail, 975 ; road, 866 ; air, 8.7 ; inland water, 435 ; pipeline, 587 . Compute the total number of cargo traffic between the United States cities as follows, Total number of cargoes = 975 + 866 + 8.7 + 435 + 587 = 2871.7 Compute the percent of the various cargo traffic of the total for each pattern as follows, Compute the percent of the rail cargo traffic of the total as follows, 975 ÷ 2871.7 = 0.3395 × 100 % = 33.95 % Compute the percent of the road cargo traffic of the total as follows, 866 ÷ 2871.7 = 0.3016 × 100 % = 30.16 % Compute the percent of the air cargo traffic of the total as follows, 8.7 ÷ 2871.7 = 0.003030 × 100 % = 0.3030 % Compute the percent of the inland water cargo traffic of the total as follows, 435 ÷ 2871.7 = 0.1515 × 100 % = 15.15 % Compute the percent of the pipeline cargo traffic of the total as follows, 587 ÷ 2871.7 = 0.2044 × 100 % = 20.44 % Now compute the central angle of the circle that represents each pattern as follows, Compute the central angle of the circle for the rail cargo traffic as follows, 33.95 % of 360 ° = 0.3395 × 360 ° = 122.22 ° ≈ 122 ° Compute the central angle of the circle for the road cargo traffic as follows, 30

For unemployed persons in the United States, the average number of months of unemployment at the end of December 2009 was approximately seven months (Bureau of Labor Statistics, January 2010). Suppose the following data are for a particular region in upstate New York. The values in the first column show the number of months unemployed and the values in the second column show the corresponding number of unemployed persons.
