Answer:
6
Step-by-step explanation:
Call pentagon p, circle c and triangle t
We have 2c + 2p = 2p + 2t + c
p = 5, t = 3 so
2c + 2(5) = 2(5) + 2(3) + c
2c + 10 = 10 + 6 + c
2c = 6 + c
c = 6
 
        
                    
             
        
        
        
Answer: Yes, we have. 
Step-by-step explanation:
Going by the details provided, Probability of success of choosing a citizen with a fitness band 27%
The probability function for expected value shows the Formula to know with sufficient dependence what proportion of the sampled people will have the fitness band. 
Since 27% of 500 = 135.
and 135 is more than a quarter of 500(125), then we have enough Evidence that more than a quarter of this age group own a fitness band.
