Step-by-step explanation:
so,
1/12 × $100
5/12 × $20
6/12 × $1
so the expected "payout" is
100/12 + 100/12 + 6/12 = 206/12 = 103/6 ≈ $17.17
minus the $2 entrance fee, the expected value is
17.17 - 2 = $15.17
but of course, there will be 6 losing $1 (while the other 6 will go home with a positive result).
Point slope eqaution is
y-y1=m(x-x1)---------equation1
find m slope=y2-y1/x2-x1
m=-3+1/3+4=-2/7
so put those all values in eqaution 1
<span>(x1, y1) as (-4, -1).</span>
y+1= - 2/7(x+4)
Radius is half that of the diameter and area =pi times radius squared then the area wouldn't be decimal format if it was while number I have no idea without looking at my notes... Coffee here I come

Answer:
x=-5, y=-2. (-5, -2).
Step-by-step explanation:
x-3y=1
-x+6y=-7
-------------
3y=-6
y=-6/3
y=-2
x-3(-2)=1
x+6=1
x=1-6
x=-5
