4800 patients
Step-by-step explanation:
120 of 1000 means 12%
12% of 40000 is 4800
Divide the first equation by 2 and add the result to the second equation. This will eliminate x.
... (-4x -2y)/2 + (2x +4y) = (-12)/2 +(-12)
... 3y = -18 . . . . . collect terms
... y = -6 . . . . . . . divide by 3
Substitute this into either equation to find x. Let's use the second equation, where the coefficient of x is positive.
... 2x +4(-6) = -12
... 2x = 12 . . . . . . . . add 24
... x = 6 . . . . . . . . . . divide by 2
The solution is (x, y) = (6, -6).
<em>l-37l=37 is the correct answer.</em>
A - Yes it is fair because <span>he relative frequency of green is the highest.</span>
That's an expression, so the only thing you can do is simplify it, but that already looks simplified.
