Mira uses the mapping rule to find the coordinate of a point that had been rotated 90° clockwise about the origin. examine mira’s solution to determine which step has an error. m(–5, –6) is rotated 90° clockwise. step 1. use the rule (x, y)g(y, –x). step 2. switch x and y coordinates: (–6, –5) step 3. multiply the new x-coordinate by –1: ((–1)–6, –5) step 4. simplify: (6, –5)

The number of hours per week that the television is turned on is determined for each family in a sample. the mean of the data is 37 hours and the median is 33.2 hours. twenty-four of the families in the sample turned on the television for 22 hours or less for the week. the 13th percentile of the data is 22 hours. approximately how many families are in the sample? round your answer to the nearest integer.
