Okay so 3/25 (OF) 140 you'd have to do 140 divided by 25 then times that answer by 3. 140 divided by 25 = 5.6. 5.6 x 3 = 16.8. You can't have 16.8 people so you round it which makes it 17 people.
        
             
        
        
        
Answer:
a
   
b
  
Step-by-step explanation:
From the question we are told that 
     The population proportion is   
 
Considering question a  
      The sample size is  
Generally the standard deviation of this sampling distribution is  
           
     
=>       
     
=>       
     
The sample proportion of cans that are recycled is 
                  
=>              
Generally the probability that 300 or more will be recycled is mathematically represented as 
          
 
        
From the z table  the area under the normal curve to the left corresponding to  1.591   is 
       
=>    
Considering question b 
Generally the lower limit of  sample proportion of cans that are recycled is 
                  
=>              
Generally the upper limit of  sample proportion of cans that are recycled is 
                  
=>              
Generally probability that between 260 and 300 will be recycled is mathematically represented as 
            
=>      
=>        
From the z table  the area under the normal curve to the left corresponding to  1.136 and  -3.55  is 
        
and 
        
So 
        
=>   
 
        
             
        
        
        
1 = x(2) - 2x - 3
1 = 2x + -2x + - 3
1 = (2x + -2x) + (-3)
1 = -3
1 - 1 = -3 -1
0 = -4
No solutions
        
             
        
        
        
For this case we must find the value of n of the following equation:

Taking common factor "n" from the left side of the equation we have:

Multiplying by 5 on both sides of the equation:

Dividing between 6 on both sides of the equation:

Thus, the value of n is 20.
