So if you want to solve for c, the best thing to do is isolate the variable. So I personally don't enjoy dealing with fractions that much until the very end, so I am going to multiple the entire equation by 
to eliminate the fraction. So now the equation is 
. In order to isolate the c variable, subtract both sides by 
, which makes it 
. Now divide both sides by g, 
. So that's what c equals in terms of f, d and g.
The standard error of the mean is given by:
where sigma is the standard deviation and n is the sample size. In this case the sample size is 10 and the standard deviation is 0.657, then the standard error is:
Therefore the standard error is $0.208.
