Answer:
x ≅ 20.10 torr
Step-by-step explanation:
Given that the equation which models blood pH in the question is;
pH(x)=6.1+log(800/x)
where;
pH = 7.7
x = partial pressure of carbon dioxide in arterial blood, measured in torr.
we are asked to find (x)
In order to do that, we use the given equation:
pH(x)=6.1+log(800/x)
since pH = 7.7
7.7 = 6.1 + log (800/x)
7.7 - 6.1 =  log (800/x)
1.6 =  log (800/x)


x = 20.09509145
x ≅ 20.10 torr
 
        
             
        
        
        
1.924 and 5.77
step 1: find the mean by adding up all the numbers and divide the sum by the number of numbers. 
step 2: find the difference between each number and the mean, square the difference
step 3: add up all the results of step 2, divide the sum by (n-1), n is the number of numbers.
step 4:  square root the result of step 3.
it is a long process.
