A.) The mean of the 8th and 9th values
Answer: 460 students
Step-by-step explanation:
Based on the information given in the question, let the total number of students that attend I.S. 59 be represented by x.
Since we've been given the information that 230 signed up for the school picnic which was 50% of all students in the school. Then, the students in the school will be:
= 50% of x = 230
0.5 × x = 230
0.5x = 230
x = 230/0.5
x = 460
Therefore, 460 students attend the school.
