A set of sociology exam scores are reported as X values and z-scores. On this exam a score of X = 75 corresponds to a z-score of z = +2.00, and a score of X = 60 corresponds to a z-score of z = -1.00. What are the values for the mean and standard deviation

whatvare the choices

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
