Six students measure the acceleration (in meters per second per second) of object in free fall. The measured values are shown. T
he students want to state that the absolute deviation of each measured value x from the mean is at most d. Find the value of d. 10.56, 9.52, 9.73, 9.80, 9.78, 10.91
The answer is 180 degrees. The rotation that maps one side
to an adjacent side is 360°/6 = 60°. This is the least rotation that plots
the regular hexagon to the aforementioned. In the least whole number of these
minimum rotations,
such as three 60° rotations to make 180°, will retain
the hexagon identical.
