Answer: opposite sides with equal length
Step-by-step explanation:
To find the percentage,here's what we can do:

The percentage would then be:
=63/420×100%
=3/20×100%
=0.15×100%
=15%
Therefore the answer is 15%.
Hope it helps!
Using the empirical rule 68% would fall within one standard deviation of the mean.
The standard deviation is given as 2 inches and the mean is 49 inches.
Since it is only one standard deviation find the lower number by subtracting the standard deviation from the mean and find the higher number by adding the standard deviation to the mean.
49 - 2 = 47
49 + 2 = 51
68% would be between 47 inches and 51 inches tall.
It is given in the question that
M is the MIDPOINT OF FG.

Since M is the midpoint of FG, therefore GM is half of FG. That is


Therefore

And FM is 13 too .
