The efficient market theory would be violated if investors earned extraordinary returns months after a company announced unexpected profits. Thus, the correct option is (d.) Investors earn abnormal returns months after a firm announces surprise earnings.
<h3>What exactly is the hypothesis of an efficient market?</h3>
The efficient-market hypothesis is a financial economics concept that asserts asset prices represent all available information. Because market prices should only react to fresh information, it is impossible to continually "beat the market" on a risk-adjusted basis.
Because the EMH is expressed in terms of risk adjustment, it can only offer testable predictions when combined with a specific risk model. As a result, financial economics research has focused on market anomalies, or departures from specified risk models, since at least the 1990s.

Answer:
b. Operating activities
Explanation:
As we know that there are two methods of cash flow statement. The one method is direct method and the other one is indirect method
Also the financing activities and the investing activities should be same calculated under both the methods
But the operating activities would be calculated differently under both the methods
In the direct method, the cash receipts and cash payment would be adjusted while an indirect method, the changes in working capital would be adjusted
Therefore the option b is correct
Answer:
The correct answer is letter "C": duopoly.
Explanation:
Duopolies are the extension of oligopolies in which two companies dominate a market. In case the two companies collude to set a price for the products or services they provide, a duopoly becomes an oligopoly. However, that practice is forbidden by U.S. antitrust laws. Airbus and Boeing represent a duopoly in the aircraft market.
Answer:
11.25; 8.75
Explanation:
On weekends,
Inverse demand function: P = 20 – 0.001Q
On weekdays,
Inverse demand function: P = 15 – 0.002Q
Let quantity demanded tickets on weekend be Q1 and quantity demanded tickets on weekday be Q2,
Profit function:
= [(20 - 0.001Q1) × Q1] + [(15 - 0.002Q2) × Q2] - [25,000 + 2.5(Q1 + Q2)]
For maximizing profit, Differentiating profit w.r.t Q1 and Q2,
⇒ (20 - 0.002Q1) - 2.5 = 0
⇒ (15 - 0.004Q2) - 2.5 = 0
Hence, solving for Q1 and Q2, we get
Q1 = 8,750
Q2 = 3,125
Therefore,
Price during weekends: P = 20 - (0.001 × 8,750)
= 11.25
Price during weekdays: P = 15 - (0.002 × 3,125)
= 8.75
