A group of participants was surveyed and the information collected shown in the partially completed contingency table below regarding the site of skin cancer. Firstly, calculate the missing values. Melanoma Other Total Head U 43 X Trunk 52 V 98 Extremities 142 112 Y Total 229 W Z Now, using the completed contingency table, select the statements from the following list that are true. Note: a statement is true only if the value you calculated from the completed contingency table, when rounded to the same number of decimal places as in the statement, is the same as the value in the statement. 18.1% of skin cancers appear on the head 71.4% of skin cancers were melanomas or appeared on the head Given the skin cancer is something other than melanoma, the probability it is not on the extremities is 0.443 Of skin cancers appearing on the trunk, 46.9% are not melanomas

Greenhouse gases trap heat and make the planet warmer. Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. In this part, you will draw two pie graphs. A pie graph is used to show how a certain quantity has been divided into several parts, as well as to show the comparisons among these parts. 1. The data table below shows the total U.S. greenhouse gas emissions by economic sector in 2013, in million metric tons of CO2. On the pie graph provided, complete the graph to show the percent of greenhouse gas emissions for each economic sector. Label each section of the pie graph with its economic sector. The percent for "Agriculture" has been drawn and labeled for you. Economic Sector Electricity Transportation Industry Commercial & Residential Agriculture Percent of Greenhouse Gas Emissions 31 27 21 12 9 80 75 70- 85 65 95 90 wlad Percent 0 100 Agri- culture 55 50 45 10 40 35 20 25 30
