The equation below models the height, h, in feet above the water for a cable in a suspension bridge at a horizontal distance, x, in feet from the beginning of the span. h = 0.0002(x - 1,955)^2 + 100
How many feet above the water is the lowest point on the cable?

Anew test for ra is being developed. the test is administered to 750 patients with ra and 750 without ra. for the sake of the question, assume the prevalence of ra in this population is 50%. of the 750 patients with ra, 575 have a positive result. of the 750 patients without ra, 150 have a positive result. what is the positive predictive value of the new test? a575/(575+150) b. 600/(600+ 150) c. 575/(575+125) d. 600/(600+ 125)
