The value of x is 0.24. Option C is correct. The frequency table is used to find the relative frequency.

A frequency table is a collection of things with the number of times they appear in the table. f is used to signify frequency.

The given data from the table is;

The subgroup count of the column = 120

The total count = 500

x is the relative frequency

The relative frequency is found as;

[tex]\rm x = \frac{ subgroup \ count }{ total \ count } \\\\ x=\frac{120}{500} \\\\\ x = 0.24[/tex]

Hence the value of x is 0.24. Option C is correct.
