1+4=5 2+5=12 3+6=21 8+11=?
ziro4ka [17]
Okay so we just need to find out the pattern...
in this case the pattern is adding..
we did 
1 + 4 = 5 
2 + 5 = 12
we figure this one out by adding 2 and 5 twice so it look like this 
2 + 5 + 5 = 12 
now moving on to our next one 
3 + 6 = 21 
so we added 3 and added 6, three times so look
3 + 6 + 6 + 6 = 21 
so now 
8 + 11 = 96 because we added 8 and added 11, eight times look..
8 + 11 + 11 + 11 + 11 + 11 + 11 + 11 + 11 = 96 
so our answer to 8 + 11 is 96!
hope this helps:)

weeeeeb [17]
Statistic significance requires that your sample be representative of the population, but I'm struggling with this because if the class is an elective then the answer would be: <span>No, it is not a valid inference because she asked all 22 students in her science class instead of taking a sample of the students in her school.
BUT if the class is required, as most science classes are, then it WOULD be a random sample of the school. So the last option would be correct. 

My guess though is that the teacher is looking for answer B.
