We know that the measure of arc AC = 92 degrees, and x and y are both inscribed angles of this arc, which means that they will have 1/2 of its measure.

Therefore, x = 1/2 (92) = 46 degrees and y = 1/2 (92) = 46 degrees

x = 46, y = 46 is your answer, or the first option

How do you solve -2(x + 3y) = 18

sergiy2304 [10]

solving equation in terms of x we get $x=-9-3y$

solving equation in terms of y we get $y=-3-1/3x$

Step-by-step explanation:

We need to solve the equation: $-2(x + 3y) = 18$

Solving the equation:

$-2(x + 3y) = 18\\-2x-6y=18$

Simplifying and finding value of x:

$-2x-6y=18\\-2x=18+6y\\-2x/-2=18/-2+6y/-2\\x=-9-3y$

We can simplify and find value of y as well:

$-2x-6y=18\\-6y=18+2x\\-6y/-6=18/-6+2x/-6\\y=-3-1/3x$

So, solving equation in terms of x we get $x=-9-3y$

solving equation in terms of y we get $y=-3-1/3x$

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.
