A plane traveling at a constant speed flew over Pittsburgh, Saint Louis, Albuquerque, on its way to Phoenix. The plane travels 550 miles froin
Pittsburgh to Saint Louis in 1 hour. Then the plane travels from Saint Louis
to Albuquerque in 1 hour and 42 minutes. Calculate the distance from Saint
Louis to Albuquerque. Explain how you determined the distance.

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

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?

Could somebody me with this radical simplification?
