To measure profitability, La Quinta used operating
margin, which is the ratio of the sum profit, depreciation,
and interest expenses divided by total revenue. The ratio is
expressed in percent form, meaning that it could theoretically take
on any value between 0 and 100, with a higher value indicating
greater profitability. La Quinta defines profitable inns as those
with an operating margin in excess of 50 percent; unprofitable inns
are those with margins of less than 30 percent. After a...

Consider a classroom filled with air. Let’s approximate air as
an ideal gas of N2-molecules (nitrogen) at normal conditions (P = 1
Bar and T = 300 Kelvin). Suppose the room has dimensions of 10 m by
10 m by 10 m (a pretty large auditorium). Let us also assume that
N2 molecule has 5 degrees of freedom (3 translational and 2
rotational). In this problem you will need to provide numeric
answers up to the first significant digit.
