In the four quarters of 2013, denoted by $$Q_1$$, $$Q_2$$, $$Q_3$$ and $$Q_4$$, Company C hired the same number of employees in $$Q_2$$ as in $$Q_1$$ and twice as many employees in $$Q_3$$ as in $$Q_2$$. The number of employees hired by the company in $$Q_4$$ was greater than the number of hired in $$Q_3$$; however, the number hired in $$Q_4$$ was also less than 3 times the number hired in $$Q_3$$. All of the employees were hired only once. If an employee is to be selected at random from all the employees hired during the four quarters, which of the following values could be the probability that the employee will be one who was hired in $$Q_4$$?

Indicate all such values.

Beginning at 1 o'clock in the afternoon, water flows into the top of the tank at a constant rate of $$x$$ gallons per minute and out of the bottom of the tank at a constant rate of $$y$$ gallons per minute. If $$ x \lt y$$, in how many minutes after 1 o'clock in the afternoon is the volume of water in the tank equal to $$\frac{1}{2}g$$, in terms of $$g$$, $$x$$, and $$y$$?
