Aplane flies around trip to philadelphia it flies to philadelphia at 220 miles per hour and back home with a tailwind at 280 miles per hour if the total trip takes 6.5 hours how many miles does the plane fly round trip

How do you create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1?

Which number line correctly shows 0.8 + 0.3?
