Suppose 200 students take an exam, graded on a scale of 0-100%. the median exam grade was 78%, the mean exam grade was 68%, and the range of scores was 40%. would you expect this distribution to be symmetric or skewed? does the distribution have a high or low variation?

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°

answer:

a=9
