## Frequency Table of Pets Owned by Students in Mr. Jones' Class The frequency table below depicts the number of pets owned by students in Mr. Jones' class. Each row in the table represents a different number of pets, while the frequency indicates the number of students who own that particular number of pets. | X (number of pets) | f (frequency) | |--------------------|---------------| | 6 | 1 | | 5 | 2 | | 4 | 1 | | 3 | 2 | | 2 | 8 | | 1 | 12 | | 0 | 4 | **Question:** How many students are in Mr. Jones' class? **Options:** - ☐ 21 - ☐ 30 - ☐ Cannot be determined. - ☐ 54 ### Explanation To determine the total number of students in Mr. Jones' class, sum the frequencies across all categories of the pets owned: \[ 1 (for 6 pets) + 2 (for 5 pets) + 1 (for 4 pets) + 2 (for 3 pets) + 8 (for 2 pets) + 12 (for 1 pet) + 4 (with no pets) = 30 \] Hence, the total number of students in Mr. Jones' class is 30.
