creativ13 [48]

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}

E(x)=\frac{140-148}{38}

E(x)=\frac{-8}{38}=-$0.2105

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.

What is the value of x?<br><br> x=______
jekas [21]

Answer:

<u>x = 39</u>

Step-by-step explanation:

Let's recall that the interior angles of a triangle always add up to 180 degrees.

Upon saying that, we have:

102 + 39 + x = 180

x = 180 - 102 - 39

x = 39

<u>The value of x is 39 degrees</u>

A cone has a volume of 5 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?
zysi [14]
Volume of a cone=(1/3)πr²h
Volume of a cylinder=πr²h

The cone has the same radius (r) and height than the cylinder that the cone fits exactly inside of.

Data:
Volume of a cone=5 in³
Then:
(1/3)πr²h=5 in³
πr²h=3(5 in³)
πr²h=15 in³   (remember: volume of a cylinder=πr²h)

Then the volume of a cylinder that the cone fits exactly inside of would be:
15 in³
