content area bottom Part 1 a. The yearly increase in the average global temperature is approximately 0.02degreesF per year. (Round to the nearest hundredth as needed.) Part 2 b. A mathematical model that estimates the average global temperature, T, in degrees Fahrenheit, x years after 1950 is Upper T equals 56.94 plus 0.02 x. (Use integers or decimals for any numbers in the expression. Use the answer from part (a) to find this answer.) Part 3 c. The model from part (b) predicts the average global temperature will be 70degreesF in 2020. (Round to the nearest hundredth as needed. Use the answer from part (b) to find this answer.)
