Assume the following group of 150 potential insured’s for health insurance:                             High risk group (50 potential insured’s)               Expected Annual Cost of Health Care Expenditures = $3600/insured                 Medium risk group (50 potential insured’s)               Expected Annual Cost of Health Care Expenditures = $2400/insured                 Low risk group (50 potential insured’s)               Expected Annual Cost of Health Care Expenditures = $1200/insured       Also assume that the insurer is unable to distinguish one class from another and yet the   insured’s have good information regarding their particular risk.   What would be the expected annual cost of health care per insured if all were insured?

The drawing depicts a hand drill – if the drill bit jams when subjected to forces as shown in the drawing (values noted below) determine the absolute values of the internal shear forces acting on the cross section of the drill bit at A. Be sure to use the correct units. a = 3 in, b = 9 in, c = 6 in, d = 6 in, e = 6 in, f (handle  from center line of drill) = 9 in. R = 10 lb, Q = 50 lb, P = 30 lb
