Fault-tolerant information systems offer 100 percent availability because they use: " redundant hardware, software, and power supplies" (Option C)
What is a Fault-tolerant information system?The ability of a system (computer, network, cloud cluster, etc.) to continue working without interruption when one or more of its components fail is referred to as fault tolerance.
The goal of developing a fault-tolerant system is to reduce interruptions caused by a single point of failure, while also assuring the high availability and business continuity of mission-critical systems or programs.
In cloud computing, fault tolerance is creating a plan for continuing current work when a few components fail or become unavailable. This allows businesses to assess their infrastructure needs and requirements, as well as deliver services when the connected devices are unavailable due to a variety of factors.

The margin of error here is 0.034.
What is margin of error?
The margin of error is a statistic that expresses the amount of random sampling error in survey results. The greater the margin of error, the less confident one should be that a poll result will accurately reflect the results of a population census. When a population is incompletely sampled and the outcome measure has positive variance, or when the measure varies, the margin of error will be positive.
Multiplying a key factor (for a specific confidence level) and the population standard deviation yields the calculation for the margin of error. The outcome is then divided by the square root of the sample's number of observations.
Mathematically, it is represented as,
Margin of Error = Z * ơ / √n
For a 99% confidence level, the critical factor or z-value is 2.58 i.e. z = 2.58.

Compare and contrast the four types of economic systems. Write 3-5 sentences.
Answer:
Explanation:
Types of economic systems:
1. Traditional economic system
The traditional economic model is built on labor, goods, and services, all of which follow well-established patterns. There is relatively little specialization or division of labor, and it is heavily dependent on individuals. The traditional economy is the oldest and most fundamental of the four types of economies.
2. Command economic system
In a command system, a sizable portion of the economic structure is under the control of a dominant centralized authority, typically the government. The command economic system, also referred to as a planned system because production decisions are made by the government, is popular in communist societies.
3. Market economic system
Free markets serve as the foundation of market economic systems. In other words, there is not much intervention from the government. The government has little influence over resources and does not meddle in significant economic sectors. The people and the link between supply and demand, on the other hand, are the sources of regulation.
4. Mixed system
The traits of the market and command economic systems are combined in mixed systems. Mixed systems are also referred to as dual systems for this reason. The phrase is occasionally used to describe a market system that is subject to strict regulatory oversight.
To know more about economic systems, visit:
https://corporatefinanceinstitute.com/resources/economics/economic-system/
Answer:
There are four types of economic systems: traditional, command, market, and mixed.
1. Traditional economic system: In this system, economic decisions are based on customs, traditions, and cultural beliefs. It relies on traditional methods of production and distribution, often in rural and agrarian societies. Examples include indigenous communities and certain rural areas where farming and bartering are prevalent.
2. Command economic system: Also known as a planned or centrally planned economy, this system is characterized by government control and ownership of resources and production. The government determines what and how much is produced, as well as the prices and distribution. Examples include North Korea and Cuba, where central authorities play a significant role in economic decision-making.
3. Market economic system: In this system, economic decisions are primarily determined by the forces of supply and demand in the marketplace. Private individuals and businesses own resources and make decisions based on profit motives. Prices are determined through competition. Examples include the United States and many Western European countries, where market forces largely dictate the allocation of resources and production.
4. Mixed economic system: This system combines elements of both command and market economies. It involves a mix of government intervention and private enterprise. Governments regulate certain industries and provide public goods and services, while allowing market forces to operate in other sectors. Examples include countries like Canada, Australia, and many European countries, where there is a blend of government intervention and private enterprise.
In summary, the four types of economic systems differ in terms of who controls the means of production and how economic decisions are made.
