In a chemical process, three bottles of a standard fluid are emptied into a larger container. A study of the individual bottles

shows that the mean value of the contents is 13 ounces and the standard deviation is 0.07 ounces. If three bottles form an i.i.d. sample,
(a) Find the expected value and the standard deviation of the volume of liquid emptied into the larger container.
(b) If the content of the individual bottles is normally distributed, what is the probability that the volume of liquid emptied into the larger container will be in excess of 39.1 ounces?

Match each gas law with the correct statement.
Serhud [2]
The correct match are as follows:

Boyles Law is about a gas at constant temperature. Therefore, the correct match would be the volume of a gas varies inversely with pressure if the temperature is kept constant.

Charles Law would be that the volume of a gas varies directly with temperature if the pressure is kept constant. 

Gay-lussac's law would be that the pressure of a gas varies directly with temperature if the volume is kept constant.
