Americans' trust in government and the media has generally been on a downward trend since pollsters first asked questions on these topics in the second half of the twentieth century. Trust in government hit an all-time low of 14% in 2014, while trust in the media bottomed out at 32% in 2016. The bar graph shows the percentage of Americans trusting in the government and the media for five selected years. Use this information to answer parts a-c. CIT Percentage 70- 60- 54 M 50 40- 36 30- Trust in media Trust in Goverment 20 10- 32 47 20 43 19 39 17 42 2003 2007 2011 2015 2019 a. Use the information in the graph to estimate the yearly loss in the percentage of people trusting in government. The yearly loss in the percentage of people trusting in government is 1.2%. (Round to the nearest tenth as needed.) b. Write a mathematical model that estimates the percentage, P, of people trusting in government x years after 2003. The mathematical model P = estimates the percentage, P, of people trusting in government x years after 2003. (Use integers or decimals for any numbers in the expression. Use the answer from part (a) to answer this part.)
