MGSES. G.6: Jason was given a triangle that had side length of 10m and a hypotenuse of 15m. When he substituted these values into the Pythagorean Theorem, he got 102 + 152 = c?.
Part A. Find Jason's mistake and correct it. Then, solve for the missing length. Round to the
nearest tenth.
Part B. Show your mathematical thinking and justify your answer.

There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the distribution of act scores in recent years has been roughly normal with mean µ = 20.9 and standard deviation s = 4.8. sat scores are reported on a scale from 400 to 1600. sat scores have been roughly normal with mean µ = 1026 and standard deviation s = 209. reports on a student's act or sat usually give the percentile as well as the actual score. the percentile is just the cumulative proportion stated as a percent: the percent of all scores that were lower than this one. tanya scores 1260 on the sat. what is her percentile (± 1)?
