Answer:
The sum of -8 and 3 is -5
Answer:
The percentage decrease is -33.93%
Step-by-step explanation:
Firstly we check if there is an increase or decrease
Since we went from 5.5 million to 3.7 million, that is a decrease
Percentage decrease = (3.7 - 5.6)/5.6 * 100%
= -1.9/5.6 * 100% = -33.93%
Considering that each student has only one birthday, each input will be related to only one output, hence this relation is a function.
<h3>When does a relation represent a function?</h3>
A relation represents a function when each value of the input is mapped to only one value of the output.
For this problem, we have that:
- The input is the student's name.
- The output is the student's birthday.
Each student has only one birthday, hence each input will be related to only one output, hence this relation is a function.
