Is there anything else? Like what is the question asking?
        
             
        
        
        
The sample size should be 250.
Our margin of error is 4%, or 0.04.  We use the formula

To find the z-score:
Convert 98% to a decimal:  0.98
Subtract from 1:  1-0.98 = 0.02
Divide both sides by 2:  0.02/2 = 0.01
Subtract from 1:  1-0.01 = 0.99
Using a z-table (http://www.z-table.com) we see that this value has a z-score of approximately 2.33.  Using this, our margin of error and our proportion, we have:

Divide both sides by 2.33:

Square both sides:

Multiply both sides by n:

Divide both sides to isolate n:
 
 
        
        
        
not sure really what the question is asking but dividing both sides of the equation by "t" is:

Answer:
-9x + 13
Step-by-step explanation:
9 -3x +(-6x) +4
you will add -3x+(-6x), then add 9+4
-3x+(-6x) = -9x   (a negative pus and negative = a negative
9 +4 = 13
-9x + 13
