pi·(7.2/2)^2·x = 2·pi·(7.2/2)^2 + 2·pi·(7.2/2)·x
x = 4.5 = 4 1/2
O = V = 1458/25·pi = 58.32·pi
 
        
                    
             
        
        
        
Answer:
x - 11 
Step-by-step explanation:
Let f(x) = -5x - 4 and g(x) = 6x - 7. 
 f(x) + g(x) 
I like to line them up vertically
 -5x - 4 
 6x - 7
--------------
x-11 
 
        
             
        
        
        
Answer:
We are 95% confident that the proportion of American voters who favor congressional term limits is 64 percent with a difference of 3% for small sample size.
Step-by-step explanation:
95 % confidence means that we are 95 % confident that the the proportion of American voters who favor congressional term limits is 64 percent.
95 % confidence  means that of all the sample about 95 %  values are within in the given range. 
And only 5% sample are not included in the given parameter.
Margin of error is the amount of miscalculation or difference in change of circumstances from the obtained data. 
3% margin of error usually occurs when the data size is small. 
As the data size increases the margin of error decreases. 
So this statement tells us that we are 95% confident that the proportion of American voters who favor congressional term limits is 64 percent with a difference of 3% for small sample size.
Margin of error= z *σ/√n→
This indicates that as the sample size decreases the margin of error increases and vice versa.
