He mean weight of a breed of yearling cattle is 11871187 pounds. Suppose that weights of all such animals can be described by the Normal model N(11871187,7878). a) How many standard deviations from the mean would a steer weighing 10001000 pounds be? b) Which would be more unusual, a steer weighing 10001000 pounds, or one weighing 12501250 pounds? a) A steer weighing 10001000 pounds is nothing standard deviations below the mean.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
