Answers

Answer 1

Feather forking in Bitcoin refers to a scenario where a block is divided into two, creating two different chains with different transaction histories.

Feather forking in Bitcoin refers to a scenario where a block is divided into two, creating two different chains with different transaction histories. This type of forking usually occurs when miners disagree on which block to add to the blockchain. Feather forking has happened in the past, but it is relatively rare, and it can be resolved by the network using the longest chain as the true chain. The network can protect itself from feather forking by using a consensus algorithm that makes it difficult for miners to create new blocks or forks. For example, Bitcoin uses a Proof of Work (PoW) consensus algorithm that requires miners to solve complex mathematical problems before they can add new blocks to the blockchain. The difficulty of the problem adjusts automatically to ensure that the network remains secure and stable. A Goldfinger attack is a type of 51% attack, where an attacker gains control of over 51% of the network's computing power, allowing them to control the network and manipulate transactions. This type of attack has never happened in the Bitcoin network, but it is a significant threat to any blockchain-based system. To protect itself from Goldfinger attacks, the network needs to ensure that no single entity or group controls more than 50% of the computing power on the network. This can be achieved by increasing the number of miners and nodes on the network and using a consensus algorithm that makes it difficult for any one entity to control the network. A replay attack is a type of network attack where an attacker copies a valid transaction from one blockchain to another. This can lead to the loss of funds or double-spending. Replay attacks have happened in the past, but they are preventable. The network can protect itself from replay attacks by implementing a replay protection mechanism that ensures that transactions on one blockchain are not valid on another. An example of a network attack not listed here is the Distributed Denial of Service (DDoS) attack. In a DDoS attack, an attacker floods the network with a large number of requests, causing it to slow down or crash. The network can protect itself from DDoS attacks by implementing a defense mechanism that filters out malicious traffic and prevents it from reaching the network's servers.

Indicate the point where a monopoly will set its price.

Answers

Answer:

A monopoly will set its price at the point where marginal cost and marginal revenue intersects or meet (MC = MR).

Explanation:

A monopoly is a market structure which is typically characterized by a single-seller who sells a unique product in the market by dominance. Thus, it is a market structure wherein the seller has no competitor because he is solely responsible for the sale of unique products without close substitutes. Any individual that deals with the sales of unique products in a monopolistic market is generally referred to as a monopolist.

For example, a public power company that serves as the only power utility (electricity) provider to the public.

Generally, a monopoly will set its price at the point where marginal cost and marginal revenue intersects or meet (MC = MR). This is simply because a monopoly would derive the maximum profit at the point where MC = MR.

A weekly report for new agents at a vacation sales company is shown in the histogram. A histogram titled Vacation Packages has number of packages sold on the x-axis and number of salespersons on the y-axis. 9 sold 1 to 2 packages; 7 sold 3 to 4; 4 sold 5 to 6; 3 sold 7 to 8; 2 sold 9 to 10; 1 sold 11 to 12; 2 sold 13 to 14; 3 sold 15 to 16. How many of the new agents sold more than 10 vacation packages?

Answers

Answer:

6 salespersons

Explanation:

A histogram shows the graphical representation of the distribution of numerical data using bars of different lengths.

From the histogram:

The number of salespersons who sold 11 - 12 packages = 1

The number of salespersons who sold 13 - 14 packages = 2

The number of salespersons who sold 15 - 16 packages = 3

Therefore the new agents who sold more than 10 vacation packages = 1 + 2 + 3 = 6 salespersons
