Total number of students in the sample = 100
Atleast 3 means equal to or greater than 3. So in order to find the number of students in the sample who play outdoor games for atleast 3 hours we need to add the number of students who play for 3 hours or more.
Therefore, number of students who play for atleast 3 hours = 62 + 8 + 0 = 70
In the sample of 100 students, 70 students play the outdoor games for atleast 3 hours.
Base on this we can the sample proportion of students who play outdoor games for atleast 3 hours = 70/100 = 0.7
Based on the sample proportion, out of 1200 students the expected number of students who will play outdoor games for atleast 3 hours = 0.7 x 1200 = 840 students
Thus, 840 students out of 1200 would be expected to play outdoor games for at least three hours every week. Option B is the correct answer
I would solve for y on the top one and sub it into the bottom one.
y=-2x+8
(12/5, 16/5)
Answer:
-2
Step-by-step explanation:
-9=4n-1
4n=-9+1
4n=-8
n=-8/4
n=-2

To compare two whole numbers to find a percent, divide the first number by the second number:
224/640 = 0.35.
Multiply the dividend by 100 to get a percent.
0.35 x 100 = 35%.</span></span></span></span></span></span>
