The velocity v of the flow of blood at a distance r from the central axis of an artery of radius r is given below, where k is the constant proportionality. v = k(r2 − r2) find the average rate of flow of blood along a radius of the artery. (use 0 and r as the limits of integration.)

The probability that a college student belongs to a health club is 0.3. the probability that a college student lives off-campus is 0.4. the probability that a college student belongs to a health club and lives off-campus is 0.12. find the probability that a college student belongs to a health club or lives off-campus. tip: p(a or b) = p(a) + p(b) - p(a and b) 0.54 0.58 0.70 0.82
