Answer:
Circumference : 18.84 inches
Radius: 3 inches
Answer:
answer is 3 and ratio of two different numbers
4 outcomes,
Heads - Heads
Heads - Tails
Tails - Tails
Tails - Heads
With every coin added the amount of outcomes is multiplied by two
3x+3y=-3
divide both sides by 3 for ease
x+y=-1
now eliminate x's
multiply that equation by 2 and add to other one
2x+2y=-2
<u>-2x+y=2 +</u>
0x+3y=0
3y=0
y=0
x+y=-1
x+0=-1
x=-1
(x,y)
(-1,0)
