Answer:
It is a many-to-one relation
Step-by-step explanation:
Given
See attachment for relation
Required
What type of function is it?
The relation can be represented as:
Where
and
Notice that the range has an occurrence of 10 (twice)
i.e.
and
In function and relations, when two different values in the domain point to the same value in the range implies that, <em>the relation is many to one.</em>
Using proportions, it is found that it took 15 days for the students to finish the project.
<h3>What is a proportion?</h3>A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
In this problem, we have that:
The compound <em>rule of three</em> is given as follows:
1 project - 5 students - 15 days
0.4 project - 2 students - x days
Increasing the number of students, the number of days is reduced, hence the measures are inverse proportional and the <em>rule of three</em> is given by:
15/x = 1
x = 15 days.
It took 15 days for the students to finish the project.
