Concept explainers
[T] An athlete runs by a motion detector, which records her speed, as displayed in the following table. The best linear fit to this data,
of l(t) between t = 0 and t = 40 to estimate the runner’s average speed.
Minutes | Speed (m/sec) |
0 | 5 |
10 | 4.8 |
20 | 3.6 |
30 | 3.0 |
40 | 2.5 |
