Relationship R is not symmetric and is not reflexive, R is not an asymmetric relation, R is a transitive relation as represented in image.
What is a relation?
- Both the relationship and the function are fairly similar to one another. After learning about function and relation, we can then study how they differ from one another. This is how we can distinguish between relation and function.
- The connection can be viewed as a set of ordered pairs in discrete mathematics. The sets must not be empty in order for it to be used to connect an object through one set to the other. The relation may include two sets or more.
- The relation in mathematics is the connection between different sets of values. Assume that there are different pairs of ordered pairs, x and y.
If set x and set y are related, then set x's values are referred to as its domain while set y's values are referred to as its range.

convert the whole number into an improper fraction then multiply
example if you have 2 1/2 convert it to 5/2
( multiply whole number by denominator than add the numerator)
Answer:
The main difference between an observational study and an experiment is the inclusion of a random sample.
Step-by-step explanation:
In an observational study, the researchers do not interfere with the method the data is collected. In an investigation of how regularly the studying improves marks, the researchers sample people from the population who has studied regularly and those who haven't and then collect the average marks obtained by each of the groups. We can only accomplish an association among the response variable and the explanatory variables because there may be some other variable that may affect both the explanatory and the response variable, thus making it look as if there is a relationship among them.
But in an Experiment, the researchers actually interfere with the method the data is collected. In an experiment, each case is randomly assigned to the treatment groups, i.e. to say that each of the cases has an equal chance of being in both groups. These kinds of studies help us to establish causal connections between the response variable and the explanatory variables because random assignment makes sure that they are equally spread among both the groups.
So, the primary difference between an observational study and an experiment is that in case of an observational study there is no random assignment but in case of an experiment there is a random assignment.
