Given:
Sales = $1,800,000
Beginning inventory = $160,000
Ending inventory = $240,000
Gross profit = $600,000

Wilkens' days in inventory for 2017 = ?
Computation of Wilkens' days in inventory for 2017:
Wilkens' days in inventory for 2017 = Number of days in a year / Inventory turnover

Answer: 
Explanation:
If r is the number of successes out of n trials , then the sample proportion of success = 
For binomial experiment , if the population probability of success p on a single trial is not given , then the best point estimate for probability of success p on a single trial is the sample proportion of successes.
i.e. a point estimate for the probability of success p on a single trial :
Hence, a point estimate for the probability of success p on a single trial =
Answer:
The correct answer is letter "C": capable of offering the give-and-take of in-person conversations.
Explanation:
While talking about channels of communication, phone calls are useful to imitate the closest possible to face-to-face communication, with its limitations. The transmission of information is done in real-time and the participants can provide their points of view just as if they were talking in person.
Though, expressions cannot be captured. Many people over the phone can pretend to have a mood modulating their tone of voice even if their feelings are opposite.
Answer:
D
Explanation:
A perfect competition is characterized by many buyers and sellers of homogenous goods and services. Market prices are set by the forces of demand and supply. There are no barriers to entry or exit of firms into the industry.
In the long run, firms earn zero economic profit. If in the short run firms are earning economic profit, in the long run firms would enter into the industry. This would drive economic profit to zero.
Also, if in the short run, firms are earning economic loss, in the long run, firms would exit the industry until economic profit falls to zero.
Profit is maximised where marginal cost equals marginal revenue.
Economics in many cases is an exact science, but usually it is a practical one that has applications. Thus there are some practical goals that need to be answered with the use of economics and an easy to summarize form of them are the five fundamental questions of economics. 3 of the choices above are such fundamental questions; determining the way of production, the receiver of the production as well as the ways in which the economic system can change are of fundamental importance to the science of economics. The other 2 questions are: What products will be produced ? and How can we foster progress?
Choice d is a pretty important question too (that falls somewhat under a) but the fact that it mentions the government specifically makes it less general than the other propositions so it is not a fundamental question.
