Collect data on one response (dependent or y) variable and two different explanatory (independent or x) variables. This will require a survey with three questions. For example: To predict a student’s GPA (y), you might collect data on two x variables: SAT score and age. So we would be trying to determine if there was a linear correlation between someone’s SAT score and their GPA, as well as their age and their GPA. (Note: students may not choose GPA as...

What are the partial derivatives of the equation y = 10^(0.7941log10(x)+log(0.0774)) with respect to m, x, and b if the equation is equivalent to y=10^(mlog10(x)+log10(b))? Keep in mind I have not taken Calculus 3 as of yet, this is for my calculus based physics lab so that I can use the partial derivative and the uncertainty to calculate the contribution of each term to the uncertainty of the calculated variable.
