Kaylee read a report that said the probability that a randomly selected American is left-handed is 14 % 14%14, percent. She was curious how many left-handed students to expect in a class of 25 2525 students. She simulated 40 4040 classes of 25 2525 students where each student selected had a 0.14 0.140, point, 14 probability of being left-handed. Kaylee counted how many left-handed students were in each simulated class. Here are her results:

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) .
