<h2>
Answer:</h2>
Continuous graph--
- The height of a plant as it grows.
- Amount of fuel and distance traveled.
Discrete graph--
- Number of students per teacher.
- Amount of chairs for each table.
<h2>
Step-by-step explanation:</h2>
In mathematics the word discrete means that it takes distinct values and continuous means that there are infinite value between each value.
1)
- Number of students per teacher.
Here as we know that a whole of a teacher would be assigned for some children this means that it takes a particular value and not all of the values especially the decimal values.
2)
- The height of a plant as it grows.
As we know that the height of a plant grows continuously over a span of time.
Hence, the graph of this situation will be continuous.
3)
- Amount of fuel and distance traveled.
Since, the amount of the fuel required over a distance will be continuous and the fuel used could be in decimals not necessarily in integers.
Hence, we will get a continuous graph for this situation.
4)
- Amount of chairs for each table.
As we know that the amount of chairs are always required as a whole.
Hence, the graph of it will be discrete.
