1) without creating a graph, how can you determine if the data is linear?

2)use technology to perform an exponential regression for each mug

3) using the mathematical model for part b) predict the temperature of the water for each mug after 20 minutes

4) the researchers test a third mug, and determine the following regression for its cooling data y= 75(0.93)x How well does the third mug insulate compared to mugs A and B?

1) without creating a graph, how can you

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. Time (min) Temp (C) Temp (C) 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
