Yes they can and it depends on what the standard deviations are. The standard deviation is a measure of how close results are to the mean, a low standard deviations means the measurements are precise, so close to the mean. A high standard deviation means that measurements are more spread out. Saying that one set is more spread out than the other.
5 is the answer ok I'll explain
We can use two different methods to find our missing angle:
Subtract the two known angles from 180° :
Plug the two angles into the formula and use algebra: a + b + c = 180°
I think that inches would be most common for height but centimeters and feet could also be used.
386 divided by 20 is 19.3 so Greg averaged 19.3 miles per gallon.
