Construct a scatterplot and identify the mathematical model that best fits the data. Assume that the model is to be used only for the scope of the given data and consider only linear, quadratic, logarithmic, exponential, and power models. Use a calculator or computer to obtain the regression equation of the model that best fits the data. You may need to fit several models and compare the values of R2.

vocaloid · Answer

ok, do you have a graphing calculator by any chance? like a TiI-84?

vocaloid · Answer

you need a calculator to solve this one

hulkart · Answer

yeah...I've got one

hulkart · Answer

I understand...

hulkart · Answer

The answers I got there are not even close...

hulkart · Answer

so is it C?...I got 0.8513

vocaloid · Answer

Ah, sorry, sorry, Just realized that my explanation is completely wrong

did your teacher show you how to find the R^2 value?

hulkart · Answer

Maybe she did....but I'm no longer in the class...I just have to do this to pass it.

vocaloid · Answer

well, ok, I just plugged this into my calculator, and the third answer gives me the highest  R^2 value, so my best guess is the third option

@hulkart please look at my last response

hulkart · Answer

Here? Do you mean the R2 thing?

anonymous · Answer

Sorry, im not great with math  myself

hulkart · Answer

Haha....at least you tried
