The table to the right shows incidence ratios for a particular group. The rational function P (x) models the percentage of smoking-related deaths among all deaths from a disease, P (x), in terms of the disease's incidence ratio, x. The graph of P (x) is shown to the right. Find P (11). P (11) = (Round to the nearest integer as needed. )

Explanation / Answer

P(x) = 100(x-1)/x when p(11) = 100(11-1) / 11 90.9 is an answer
