Answer:
The answer is nearest-neighbor learning.
because nearest neighbor learning is classification algorithm.
It is used to identify the sample points that are separated into different classes and to predict that the new sample point belongs to which class.
it classify the new sample point based on the distance.
for example if there are two sample points say square and circle and we assume some center point initially for square and circle and all the other points are added to the either square or circle cluster based on the distance between sample point and center point.
while the goal of decision tree is to predict the value of the target variable by learning some rules that are inferred from the features.
In decision tree training data set is given and we need to predict output of the target variable.

Answer:
The challenge of cost control
The challenge of competence
The challenge of reduced system delivery times.
Explanation:The Challenge of Cost control is a major challenge affecting the software engineering in the 21st century,the cost of Microchips and other hardware are constantly rising.
The challenge of competence is another major challenge affecting software engineering in the 21st century,as most software engineers lack the required competence to handle some of the issues facing softwares.
The challenge of reduced system delivery times is a major challenge likely to affect software engineering in the 21st century,as people required the software to be available in the shortest possible time.
<h2><u>Answer:</u></h2>
A hazard explicitly connected with private streets is "a lot of people on foot, cyclists and left vehicles".
There are somewhere around ten kind of risk when driving through local locations yet the most pivotal is the left vehicles as I would like to think as thee autos might shroud a little youngster behind hanging tight to cross the street and going to run
. So it is never shrewd to simply glance through the street in such zone as that may cause genuine inconveniences.
Answer:
PowerPoint is the standard forms of software platform. It contains the CPU, memory, expansion slots and all the controllers required to control standard hardware devices.
Answer:
Constraint is defined as a part of individual attribute or column. In terms of computer programming, constraints relation are stated in the form of variable. Basically, constraint is the rule that are use for optimization purpose.
There are different types of constraints that are:
- Primary key constraint : It is defined as, the combination of columns which uniquely identify each data in the database table.
- Unique constraint : Unique constraint are used to ensure that all the values in the column table in the database are must be different.
- Not null constraint : It basically prevent all the null values from entering into one or more than one column in a table.
