Ms Sue can you help me in biology
30% of students bring lunch. Total students are 300.
So, 30% of 300 student is 90. (300 x 30/100 = 90 )
So 90 out of 300 bring lunch. That means students who do not bring lunch are 300 - 90 = 210.
Answer is 210 students do not being their lunch.
OR
30% of students bring lunch. So 70% of 300 students do not bring lunch.
So, 300 x 70/100 =210.
Answer = 210 students do not bring lunch
To find the number of students who bring their lunch to school, you can multiply the percentage of students by the sample size.
Given that the survey showed that 30% of students bring their lunch to school and the sample size is 300 students, you can calculate the number of students who bring their lunch as follows:
30% of 300 students = (30/100) * 300 = 0.3 * 300 = 90 students
Therefore, the survey indicates that 90 students bring their lunch to school.
