It’s basically the same thing as -4=20 so your answer would be -5 or D
        
                    
             
        
        
        
Answer:
 
  
And rounded up we have that n=421
Step-by-step explanation:
We know that the sample proportion have the following distribution:

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 90% of confidence, our significance level would be given by  and
 and  . And the critical value would be given by:
. And the critical value would be given by:
 
The margin of error for the proportion interval is given by this formula:  
 (a)
    (a)  
And on this case we have that  and we are interested in order to find the value of n, if we solve n from equation (a) we got:
 and we are interested in order to find the value of n, if we solve n from equation (a) we got:  
 (b)
   (b)  
We assume that a prior estimation for p would be  since we don't have any other info provided. And replacing into equation (b) the values from part a we got:
 since we don't have any other info provided. And replacing into equation (b) the values from part a we got:
 
  
And rounded up we have that n=421
 
        
             
        
        
        
Answer:
y=-x-2
Step-by-step explanation:
y+5=-(x-3)
y+5=-x+3
y=-x+3-5
y=-x-2
 
        
                    
             
        
        
        
The answer is 101.0769236761231
but just write 101 because i think the others are no need to write and
if you want to divide use your calculator
