Answer:
164 respondents answered "yes"
69 respondents answered "yes"
126 respondents answered "yes"
Step-by-step explanation:
Let's take these problems one at a time.
First problem: 195 Juniors and 215 Seniors. 2 out of 5 answered "yes".
Now let's first find the total number of students.
Total Students = 195 + 215
Total Students = 410
Now 2 out of 5 also means the 2/5 or 40% of the students answered yes.
To see how many said yes, we simple multiply the total number of students to the value of 40% or 0.40.
Total Students that answered "yes" = 410 x 0.40
Total Students that answered "yes" = 164
Second Problem: 125 Juniors and 220 Seniors. 0.80 answered "no".
Same process, we first look for the total number of students.
Total Students = 125 + 220
Total Students = 345
Now 0.80 or 80% of them said "no".
We take the total number of students and multiply the number of students to the value of 80% or 0.80.
Total Students that answered "no" = 345 x 0.80
Total Students that answered "no" = 276
Now to find out how many answered "yes", we subtract the total number of students to the students that said "no".
Total Students that answered "yes" = 345 - 276
Total Students that answered "yes" = 69
Third Problem 200 Juniors and 160 Seniors. 35% answered "yes"
Same process, we first look for the total number of students.
Total Students = 200 + 160
Total Students = 360
To see how many said yes, we simple multiply the total number of students to the value of 35% or 0.35.
Total Students that answered "yes" = 360 x 0.35
Total Students that answered "yes" = 126
