Class members read the following number of pages over the weekend: 9, 11, 7, 10,9,8,7,13,2,12,10,9,8,10,11,12. which number is an outlier? explain your. reasoning. (you can draw a line plot to you find outliers.)

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
