Use technology to perform an exponential regression for each mug

Using the mathematical model from part b), predict the temperature of the water in each mug after 20 minutes.

The researchers test a third mug, and determine the following regression equation for its cooling data: y = 75(0.93)^x

By comparing the regression equations, how well does the third mug insulate compared to mugs A and B?

- "' Ashley Noseworthy: Attempt 1 A manufacturer is testing the performance of insulating mugs in cold weather. They pour hot water into each mug and record the temperature over a period of time. The results are shown in the table below. Temp (C) Temp PC) Time (min) Mug A Mug B 0 75.0 75.0 2 60.8 55.5 4 49.2 41.0 6 39.9 30.3 8 32.3 22.4 10 46.2 16.6 12 21.2 12.3 14 17.2 9.0 Question 9 (1 point) Without creating a graph, how can you determine if the data is linear
