Liz flips a coin 70 times. the coin lands heads up 49 times and tails up 21 times. Complete each statement the theoretical probability of the coin landing heads up is_%

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) .

Write two point-slope equations for the line passing through the points (6, 5) and (3, 1)
