how to properly solve for this on a ti84?
sum(f*X^2)=(2*37^2)+(4*42^2)+(6*47^2)+(10*52^2)+(5*57^2)+(1*62^2)=
the correct answer is 70,177 but i dont see how they got that on the calculator

Answer 1

I'm not really sure what you mean
(2*37^2)+(4*42^2)+(6*47^2)+(10*52^2)+(5*57^2)+(1*62^2)=(A Constant)
so add up the numbers....
