Final answer:
To determine the number of students represented by 8 symbols in Jane's picture graph, where each symbol equals two students, we multiply 8 (symbols) by 2, resulting in 16 students.
Step-by-step explanation:
In Jane's picture graph, if one symbol represents two students, and one row in the picture graph has 8 symbols, we can find out how many students that represent by performing a simple multiplication.
Since each symbol equals two students, we multiply the number of symbols by 2:
Number of students = Number of symbols × Value of each symbol
Number of students = 8 × 2
Number of students = 16
Thus, one row with 8 symbols represents 16 students.
