Avalue of two standard deviation from the mean is more likely to occur than a value three standard deviations from the meantrue or false

This is true. The closer to the mean that a value is, the more likely it is to occur.

In this case, two and three standard deviations away are both fairly unlikely, however, two is still more likely to occur than three.

idk

step-by-step explanation:

do it yourself, cause that made me do it myself today, in english!

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
