K The bar graph gives the average global temperature for eight selected years. Average Global Temperature 59- a. Estimate the yearly increase in the average global temperature, rounded to the nearest hundredth of a degree. b. Write a mathematical model that estimates the average global temperature, T, in degrees Fahrenheit, x years after 1950. c. If the trend shown by the data continues, use your mathematical model from part (b) to project the average global temperature in 2040. degrees Fahrenheit 58.18 58.07 58- 57.51 57.34 57.37 56.98 57.04 57.06 57- 56- 1950 1960 1970 1980 1990 2000 2010 2015
