The XYZ Data Corporation has assigned three perspective new
apprentices to collect data on the corporation’s current computer
processing demands to determine which apprentice should be hired.
The corporation knows that its data usage is modeled by a linear
function, since each new client added has approximately the same
computer processing requirement. Your supervisor at XYZ has
assigned you the task of reviewing the data collected by the three
apprentices to determine which apprentice collected the data
accurately. Additionally, you...

approximation to the binomial distribution, where p = 0.15 and q =
0.85. (Round your answer to four decimal places.) Incorrect: Your
answer is incorrect.

According to test data, a new type of engine takes in streams of
water at 200 °C, 3 bar and 100 °C, 3 bar. The inlet ratio of the
mass flow rate of the higher temperature stream to lower
temperature stream is 4. A single stream exits at 3.0 bar with a
mass flow rate of 5400 kg/h. There is no significant heat transfer
between the engine and its surroundings, and kinetic and potential
energy effects are negligible. For operation...
