Answer:
It is true, that in a management information system, the quality of information is determined by its usefulness to users, and its usefulness determines the success of the information system.
Explanation:
A management information system (MIS) is a computerized and centralized database that collects data from many different resources in the organization. And, then processes and organized the data in a way that would be useful and helpful in making a business decision. These days, for both large and small organization, collection of data and use of technology are so prevalent and these organization collecting the data from their businesses resources daily even hourly such as daily sale, daily expense, hourly wages, etc, and then managing it in a way to make a right business decision. A good MIS in an organization gives a competitive advantage because it turns the data into usable and into helpful information that can be used in making business decisions and strategy and to increase profit.
However, the information quality is based on its usefulness to the user or to the organization. Because if the MIS produces the information that is not useful to the user, the information and use of MIS are useless in the organization because the information that is required in making a business decision is not useful.
If the MIS produces the quality information to its user in making the right business decision and organization or user take the right decision that brings profit to the organization. Then, this use of information determines the success of an information system in an organization.
For example:
In a Bakery, the MIS produce the right information in making decision e.g. MIS produce information to bakery owner that on valentine day, most people buy chocolate. Then, the owner tries to meet the demand for chocolate on valentine's day. Therefore, this is the quality of information and it is determined by its usefulness to the bakery owner and its usefulness determines the success of MIS.

Explanation:
Machine Learning refers to a concept of teaching or empowering systems with the ability to learn without explicit programming.
Supervised machine learning refers to a Machine learning concept whereby the system is provided with both features and label or target data to learn from. The target or label refers to the actual prediction which is provided alongside the learning features. This means that the output, target or label of the features used in training is provided to the system. this is where the word supervised comes in, the target or label provided during training or teaching the system ensures that the system can evaluate the correctness of what is she's being taught. The actual prediction provided ensures that the predictions made by the system can be monitored and accuracy evaluated.
Hence the main difference between supervised and unsupervised machine learning is the fact that one is provided with label or target data( supervised learning) and unsupervised learning isn't provided with target data, hence, it finds pattern in the data on it's own.
A to B mapping or input to output refers to the feature to target mapping.
Where A or input represents the feature parameters and B or output means the target or label parameter.
COMPLETE QUESTION
I. public class Test {
public static void main(String[] args){
System.out.println("Welcome to Java!");
}
}
II. public class Test { public static void main(String[] args) {System.out.println("Welcome to Java!");}}
Answer:
Both codes will compile and run and display Welcome to Java, but the code in II has a better style than I
Explanation:
When written codes, paying attention to proper coding styles and efficient memory management enables us to create programs that are highly efficient, coding styles refer to proper indentions and avoiding too lenghty lines of code (as is in code I), adding approprite comments etc.
