Answer:
Following are the solution to this question:
Step-by-step explanation:
We used sampling technique to collect samples throughout the instance of Options a and b because here each successive sample frame has the same gap of 10 (in the example) and in 'b' is 1, but we use a simple random sampling in 'b' and 'c' to collect the test because they can't follow any specific pattern from of the collecting systems here.
Answer:
I think the answer should be floor 4 but since floor 5 is the closest I would go for that.
Step-by-step explanation:
there are 5 members initially in the group if every member has to bring 2 members and those 2 members have to also bring in 2 other members that mean 4 people that are brought in by one person and if there are 5 people in a group that means 20 people are brought in one floor if 20 * 4 is 80 plus the initial 5 members so they only need 4 floors to have at least 80 members.
Parenthesis first
19- (4+2) - 15 / 3
19-(6)-15 / 3
then division
19-6-5
then subtraction from left to right.
19-6= 13
13-5= 8
your final answer is 8
9*4 equal is 36 divide that and your answer is 4
