- Chinese New Year A survey of people attending a Lunar New Year celebration in Chinatown yielded the following results: 120 were women; 150 spoke Cantonese; 170 lit firecrackers; 108 of the men spoke Cantonese; 100 of the men did not light firecrackers; 18 of the non-Cantonese-speaking women lit firecrackers; 78 non-Cantonese-speaking men did not light firecrackers; 30 of the women who spoke Cantonese lit firecrackers. a. How many attended? b. How many of those who attended did not speak Cantonese? c. How many women did not light firecracker? d. How many of those who lit firecrackers were Cantonese speaking men?arrow_forwardOil ProductionThe following table shows the amount of crude oil in billions of barrels produced in the United States in recent years. Source: U.S. Energy Information Administration. Year Crude Oil Produced 2002 2.097 2003 2.060 2004 1.989 2005 1.893 2006 1.857 2007 1.853 2008 1.830 2009 1.954 2010 2.000 2011 2.063 2012 2.377 In this exercise we are interested in the total amount of crude oil produced over the 10-year period from mid-2002 to mid-2012, using the data for the 11 years above. One approach is to sum up the numbers in the second column, but only count half of the first and last numbers. Give the answer to this calculation. Approximate the amount of crude oil produced over the 10-year period 2002-2012 by taking the average of the left endpoint sum and the right endpoint sum. Explain why this is equivalent to the calculation done in part a. This is also equivalent to a formula known as the trapezoidal rule, discussed in the next chapter. If your calculator has a cubic regression feature, find the best-fitting cubic function for these data, letting t=0 correspond to 2000. Then integrate this equation over the interval [2.12] to estimate the amount of crude oil produced over this time period. Compare with your answer to part a.arrow_forward
