A square with sides that measure 8 cm is continuously rotated about one of its sides to form a three-dimensional object. The three-dimensional object is a
1) cylinder with a diameter of 8
2) cylinder with a diameter of 16
3) cone with a diameter of 8
4) cone with a diameter of 16

If f(x) = 2x + 8 and g(x) = x4, what is (gº)?

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)
