Amedical insurance plan reimburses $100 per day, up to a maximum of five days, for each day the policy
holder is hospitalized. it is estimated that the probability that any person is hospitalized for exactly one
day is 0.001, for exactly two days is 0.002, for exactly three days is 0.003; for exactly four days is 0.004,
and for five or more days 0.008. the annual premium is $10.
(a) construct the probability distribution for x, the number of days hospitalized.
(b) find the mean number of days hospitalized.
(c) construct the probability distribution for y, the profit (or loss) of each policy.
(d) if fifty thousand of such policies were sold, find the expected profit (or loss).

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
