linear regressions / logarithmic regressions / exponential regressions

1. The data below represents how many cookies some muppet eats over time (in minutes). For all of this problem, you can round to two decimal places. time (r) 1 2 4 9 16 cookies (y) 10 16 21 25 28 (a) (4 points) Find the best fit for the data using logarithmic regression (LnReg). (b) (5 points) If 20 cookies were consumed, how long did it take? (Use your equation from (a) please!) (c) (5 points) How many cookies were eaten in 5 minutes? (Use your equation from (a) please!) 2. The data represents the temperature in an oven over time (in minutes) since the oven has been turned off. For all of this problem, you can round to two decimal places. time (r) 6 10 20 45 degrees (y) 327 275 182 141 80 (a) (4 points) Find the best fit for the data using exponential regression (ExpReg). (b) (5 points) After 33 minutes, how hot is the oven? (Use your equation from (a) please!) (c) (5 points) If the oven was 200 F, how much time had passed? (Use your equation from (a) please!)
