Answer:
106
Step-by-step explanation:
It is 9 because 11 minus 2 is equal to 9.
Add subtraction multiplication and division
8y-4x=2x+12y
x+2y+8y-4x=180
10y-3x=180
x+2y+2x+12y=180
14y+3x=180
24y=360
y=15
8(15)-4x=2x+12(15)
120-4x=2x+180
120=6x+180
-60=6x
x=-10
This type of sampling would be Random Sampling.
