(use the draw function if easier than the equation....)

Answer 2

I honestly have no idea what standard deviation even is.
I only knew the first 4/13 because they had to do with median and mode. I hate statistics. AND math in general XD

Answer 3

I suggest you major in film studies or burger flipping
