A sample has a mean of 120 and a standard deviation of 20.0. Find the value x that corresponds to each of these standard scores. Use the following formula:
A steam power plant has a high pressure of 3 MPa, and it maintains 60°C in the condenser. A condensing turbine is used, but the quality should not be lower than 90% at any state in the turbine.
