Step-by-step explanation:


















Hence, the correct answer is 
 
        
             
        
        
        
Y= -75x +1725
y= -75(20) +1725
y = -1500 + 1725
y= 225 = range
225= -75x +1725
225 - 1725= -75x
-1500=-75x
-1500/-75 = -75x/-75
x = 20 = domain
        
             
        
        
        
Answer:
The concentration of hydrogen ions in moles per liter (M) is 
Step-by-step explanation:
As we know 
The hydrogen ion concentration of any solution at pH is given by 

Substituting the given values in above equation, we get - 
 mol/l
 mol/l
The concentration of hydrogen ions in moles per liter (M) is 
 
        
             
        
        
        
1 to 3 
Since you know that he landed on tails 8 out of 32 times, he must have flipped heads for the flips he did not flip tails. So, subtract 32 minus 8, which equals 24, and your answer is 8 to 24. Simplify this like you would with a fraction; the greatest common factor is 8 so divide the "numerator" and the "denominator" by 8. Therefore your final answer is 1 to 3.
