To receive a C grade, a student must average more than 7777 but less than or equal to 8585. If Noah received a C in the course and had five grades of 7373, 8585, 7373, 6969, and 7878 before taking the final exam, what were the possible grades for his final if there were 100100 points possible? (Assume all six grades are weighted equally and let x represent the unknown score.)

Recently a community college offered a 2-credit course to help students with math anxiety. At the beginning of the course, each student took a 30-question survey (called MARS-S); the higher the score, the more anxiety experienced by the student. The nine students remaining in the class took the same survey at the end of the course. The before and after scores for each of the nine students who completed the course are shown below, student before after 1 72 69 66 52 3 83 71 97 85 95 61 78 45 95 56 8. 52 43 93 62 Compute the correlation between before and after scores for these students.
