400
Explanation:
1/3 of 600 is 200. That represents the boys.
Subtract 200 from 600, you get 400. That represents everybody else in the sample size (in this case, girls).
a square has four equal sides so 12 ÷ 4 = 3, so each side is 3 then, 3+3+3+3 = perimeter.
check the picture below.
The slope of a line can be calculated from any two points on that line.
slope=m=(y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are two points.
In this case:
m=(6-6)/(4--2)
m=0/6
m=0
Since the slope is zero, this is just a horizontal line, specifically the line:
y=6
Add -1/3 plus -2/5. And then multiple that fraction by what ever is in the () and then I think that's it
The slope is the coefficient of the variable. In this case, -1/4 is before the x. So the answer is C
