Page< 3 of 3 Let f(x) be the probability density function graphed below on the interval 0 < x <40 and assume that f(x) is zero elsewhere. 1. Find k. k == 2. Find the centroid of the region above, given that Mr 1350 and My = 80 p. Does this make sense graphically? 3. Find the mean value of the probability density function on 0 < x < 60.
