Hello,
You have to know this property:
C'=1.5
c/c'=d/d'
c/1.5=8
c=12
hope that helps :)
Answer:
The answer is C, 488 cm2
Step-by-step explanation:
Answer: No. The intervals defined by the margin or error overlap
Step-by-step explanation:
If we think about it, with the worst margins, 55% could be 48% and then the 45% would be 52%, showing there is no clear yes or no and it is possible that the intervals could overlap
