Answer:
18 feet
Step-by-step explanation:
Perimeter=2(l+b)
80=2(w+w+4)
80=2(2w+4)
80=4w+8
80-8=4w
72/4=w
W=18 feet
Answer:
The expected value of the game to the player is -$0.2105 and the expected loss if played the game 1000 times is -$210.5.
Step-by-step explanation:
Consider the provided information.
It is given that if ball lands on 29 players will get $140 otherwise casino will takes $4.
The probability of winning is 1/38. So, the probability of loss is 37/38.
Now, find the expected value of the game to the player as shown:
![E(x)=(140)\times \frac{1}{38}+(-4)\times \frac{37}{38}](https://tex.z-dn.net/?f=E%28x%29%3D%28140%29%5Ctimes%20%5Cfrac%7B1%7D%7B38%7D%2B%28-4%29%5Ctimes%20%5Cfrac%7B37%7D%7B38%7D)
![E(x)=\frac{140-148}{38}](https://tex.z-dn.net/?f=E%28x%29%3D%5Cfrac%7B140-148%7D%7B38%7D)
![E(x)=\frac{-8}{38}=-$0.2105](https://tex.z-dn.net/?f=E%28x%29%3D%5Cfrac%7B-8%7D%7B38%7D%3D-%240.2105)
Hence, the expected value of the game to the player is -$0.2105.
Now find the expect to loss if played the game 1000 times.
1000×(-$0.2105)=-$210.5
Therefore, the expected loss if played the game 1000 times is -$210.5.
