My first ever 200 (228), so the practice is helping.http://texasmath.org/DL/UIL2012C.pdf
A few questions:
#37: Converted the roll length into centimeters...is this a scaling problem? What do I do next?
#38: Is there a formula for this?
#46: Is this another scaling problem? Or do I "knead" to know the formula for surface area of a doughnut?
#47: I have a TI-84+. Is there an option for Inverse Regression, or is there another way to do this?
