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
Answer:
its 13 mark me as brainlist pls:)
Step-by-step explanation:
X=7/5 and 7/5=1.4so x=1.4
Answer:
B=-5
Step-by-step explanation:
Slope=rise/run
The line passes in
P1(-1,3)
and
P2(0,-2)
So slope=(3-(-2))/(-1-0)=5/-1=-5
If you divide 12 by 384 and put it in a calculator you get 32.this means 12 goes 32 times in 384
