Answer:
23
Step-by-step explanation:
The median is the number in the middle of the data once it is organized from least to greatest, so that is what we must do first.
There are 19 numbers, that means that the 10th value will be the number in the middle
This means that the median is 23
37.5
the triangle is enlarged by a factor of 2.5 so you multiply all of the numbers in XYZ by 2.5 then add them
15+10+12.5=37.5 units
y > -15
y is bigger than -15
= -14 , -13 , -12 , -11 , -10 , etc . . .
