I'm terrible at math any here is appreciated.

Which graph represents the solution set for the given system of inequalities? x+2y< 3 x+y> 4 3x-2y> 4

Which statements are true about box plots? check all that apply. they describe sets of data. they include the mean. they show the data split into four parts. they show outliers through really short “whiskers.” each section of a box plot represents 25% of the data.
