A cab driver received ratings as feedback from 20 customers on a given day, which are as follows:

7, 9, 8, x, 6, 9, 7, 5, 9, 10, 7, 8, 9, 8, 8, 7, 10, 6, 6, 9

If the relative frequency of rating 7 is 0.25, then what is the value of $ x $?

The total number of ratings given is 20. Since the relative frequency of rating 7 is 0.25, we can multiply the total number of ratings by 0.25 to find the frequency of rating 7.

Using the formula:

Frequency of rating 7 = Total number of ratings * Relative frequency of rating 7

Frequency of rating 7 = 20 * 0.25 = 5

So, the value of x in the given ratings is 5.
