Question 66
Easy

A student investigated the rate of cooling of a beaker of hot water. The table below shows their results.

Time in minutesTemperature in °C
080
264
452
649
836
1031
1228

The student plotted these results on a grid, shown in Figure 2 below.

A graph with Time in minutes on the x-axis ranging from 0 to 14 and Temperature in °C on the y-axis ranging from 20 to 90. Seven data points are plotted as small crosses at (0, 80), (2, 64), (4, 52), (6, 49), (8, 36), (10, 31), and (12, 28).

Draw a curve of best fit on Figure 2.
