A 12.0-cm segment makes a 108.0-degree angle with a 16.0-cm segment. To the nearest tenth of a cm, find the third side of the tr
Dominik [7]

Begin by using the cosine rule to find the unknown side.

Where a- unknown side, b is 12, c is 16 and angle in between is 108° 

The cosine rule...

        a² = b² + c² - 2bc cosA

            = 12² + 16² - (2×12×16 cos108°)

            = 518.655076

Taking the positive square root...

         a = 22.774 

         a = 22.8 cm nearest tenth

PLEASE!!!!!!!!!! HELP NEEDED QUICK

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) \\  \\ 
E= \frac{1}{4}  \\  \\ 
E=0.25

Thus, the option C gives the correct answer
