To find: Whether the set of numbers in each table is proportional or not.

Answer to Problem 6.4.6EP
The set of numbers in the table is non-proportional.
Explanation of Solution
Given information:
The table of the set of numbers:
The columns in the table represent the different rates of temperature in degree Celsius to temperature in degree Fahrenheit.
Here, the rate in the first column can be written in proportion as:
The rate in the second column can be written in proportion as:
The rate in the third column can be written in proportion as:
The rate in the fourth column can be written in proportion as:
It is seen that each proportion is notequal to each other.
Hence, the set of numbers in the table is non-proportional.
