To best plot the data on the graph paper, choose A as 10 (nearest multiple of 10 below the minimum time value) and B as 140 (nearest multiple of 10 above the maximum time value).
To find the best scale for plotting the data on the graph paper, we need to determine the appropriate values for A and B.
a) Value for A:
- A represents the starting point on the horizontal axis. It should be chosen to include all the data points comfortably. We can choose A as the smallest multiple of 10 that is less than the minimum time value (14 seconds in this case). Therefore, A = 10.
b) Value for B:
- B represents the ending point on the horizontal axis. It should be chosen to include all the data points comfortably. We can choose B as the largest multiple of 10 that is greater than the maximum time value (135 seconds in this case). Therefore, B = 140.
Therefore, the best scale for plotting the data would be from 10 to 140 seconds on the horizontal axis.
