Chance of winning $100 = 1/1000
<span>chance of winning $50 = 5/1000 = 1/200 </span>
<span>cost of ticket = -1 </span>
<span>E[x] = 100* 1/1000 + 50* 1/200 -1 </span>
<span>= 0.1 + 0.25 - 1 = -0.65
Hope this helps</span>
Answer:
No.
Step-by-step explanation:
Substitute in the coordinate (0, 0) and the resultant expression is:
0 > 2(0) + 3
0 > 3
We know that this is false, so it is not a solution to that inequality.
Since a cube has all equal sides, its surface area is 6 time the area of a single side. Each side has an area of a perfect square which is just the side length squared so:
A=6s^2 so if the edge length is 4.5m
A=6(4.5^2)
A=6(20.25)
A=121.5 m^2
Answer:
True
Step-by-step explanation:
2(x+3) = 5x+6-3x
2x+6=5x-3x+6
2x+6=2x+6
