How many solutions does have 3x-6=3(x-2)<br>​
Anarel [89]

Answer:

Infinite.

Step-by-step explanation:

3x-6=3\left(x-2\right)

Expand:

3x-6=3x-6

Add 6 to both sides:

3x-6+6=3x-6+6

3x=3x

Subtract 3x from both sides:

3x-3x=3x-3x

0=0

No matter what x is, it doesn't affect the answer. Thus, the equation is true for all values of x.

We have to find the expected value for the PlayBall lottery. 
The price of the ticket = $1
Prize amount = $250
If a player wins, he will be winning $249 as the price is not paid back along with the prize amount. He is spending $1, getting back $250, so the net amount he is getting back is $249.

Now we have to find the probability of winning and losing.

Number of letters from A to T = 20
Number of digits from 0 to 9 = 10

Probability of picking up the same letter that was picked on that day = 1/20
Probability of picking up the same number that was picked on that day = 1/10

Thus, the Probability of picking up the same letter and same number that was picked on that day = \frac{1}{20}* \frac{1}{10}= \frac{1}{200}

Thus, the probability of winning = 1/200

The probability of losing = 1- \frac{1}{200}=\frac{199}{200}

The expected value E for the PlayBall lottery will be:

E= \frac{1}{200}(249)- \frac{199}{200}(1) \\  \\ &#10;E= \frac{1}{4}  \\  \\ &#10;E=0.25

Thus, the option C gives the correct answer
