(10') for persons infected with a certain form of disease, the length of time spent in remission is described by the continuous pdf fy(y)-|y2, 0 y < 3, where y is m easured in years. (a) what is the average length of time that a patient spend in remission? (b) what is the probability that a patient's remission lasts longer than 2 years? 3. (10) a box is to be constructed so that its hight is 5 inches and its base is y inches by y gy-gy2,0 < y < 1 find inches, where y is a random variable describedby the pdf fy(y) the expected volume of the box 4. (10') suppose that on-the-job injuries in a textile mill occur at the rate of 0.1 per day. (a) what is the probability that two accidents will occur during the next (ive-day) work week? (b) if someone gets injured today, what is the probability that a week (ive days) or more will elapse before another injury occurs? 5. (10') in an experiment, probes land at random in the interval [0,2] on the r-axis. (a) what is the probability that a probe lands in the interval (0,1/21? (b) if three probes operate independently and lands, what is the probability that exactly two probes land in the interval [0, 1/2]? (150 lft y be a uniform random variable on the interval [2,3)

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
