Verify green's theorem for the line integral (we are going to drop the "o" for orientation on integral signs - everything we now do must be properly oriented) | r’ydx – z> y? dy jc where c consists of the parabola y = x2 – 4 from (3,5) to (-3,5) and the line segment from (3,5) to (-3,5).

Scores on a university exam are normally distributed with a mean of 78 and a standard deviation of 8. the professor teaching the class declares that a score of 70 or higher is required for a grade of at least “c.” using the 68-95-99.7 rule, what percentage of students failed to earn a grade of at least “c”?
