D is correct. The median is 28, Q1 is 22, Q3 is 38
The correct answer is D. Because, x-8>-3 is x>5 and x>5 on a graph is choice D
No
Let the groups be x and 2x
Its decimal not natual so can't be divided
The sum of angle around a point equal 360°
so (BOA) = 360-250=110°
and the sum of angle in the shape CAOB = 360°
so BCA = 360-(110+90+90)= 70°
THE ANSWER IS C.70°
A simple diagram will show you the intersection of altitudes is in the 2nd quadrant. It must have x-coordinate -2, as the altitude to the "base" y=10 must be the vertical line through (-2, 4).
The appropriate choice is ...
... C: (-2, 12)
