Answer: 
Step-by-step explanation:
In the geometric sequence we can see each time we are dividing by 5. That is the same as multiplying by  so that is the common ratio.
 so that is the common ratio.
 
        
             
        
        
        
Answer:
Probability of at least two cuckoo eggs is 0.738. 
Step-by-step explanation:
probability of cuckoo egg = 0.1 
probability of not a cuckoo egg = 1 - 0.1 = 0.9 
Probability of at least two cuckoo eggs is 
= Probability of two cuckoo eggs x probability of 1 not cuckoo egg +
probability of three cuckoo eggs 
= 0.1 x 0.1 x 0.9 + 0.9 x 0.9 x 0.9 
= 0.009 + 0.729 
= 0.738

Answer: Well... does it give you the approximate length or actual length of the butterfly? If so, you would take that length and multiply it by 5. That would give you the length of the 5 butterfly lined up together.
If it does not give you the approximate length or actual length, look up the length on google.  (Google Answer- Size: 2.5" - 4.0" range.)
Take that and multiply it by five to get the length of the 5 butterflies.
