in a certain game, a fair die is rolled and a player gains 20 points if the die shows a 6. if the die does not show a 6, the pla
BaLLatris [955]

The expected gain or loss is an illustration of mean and expected values.

The expected total gain is 83 points

The given parameters are:

  • Addition of 20 points for rolling a 6
  • Removal of 3 points for not rolling a 6

The probability of rolling a 6 in a fair die is 1/6.

The probability of not rolling a 6 in a fair die is 5/6.

So, the expected gain in each game is:

\mathbf{E(x) = 20 \times \frac 16 - 3 \times \frac 56}

\mathbf{E(x) = \frac{20}6 -  \frac{15}6}

Take LCM

\mathbf{E(x) = \frac{5}6}

\mathbf{E(x) = 0.83}

The number of games is 100.

So, the expected gain is:

\mathbf{Gain = 100 \times 0.83}

\mathbf{Gain = 83}

Hence, the expected total gain is 83 points

In the table below, y varies inversely as x. What is the missing value?
Minchanka [31]

Answer:

<h2>The value of y is <u>0.5</u>, so the answer is <u>C</u>.</h2>

Step-by-step explanation:

Find first the constant of variation.

Given: x = 3, y = 4

Find: k = ?

Formula:

y =  \frac{k}{x}

Solution:

y =  \frac{k}{x}  \\ 4 =  \frac{k}{3}  \\ 12 = k

Then, find the value of y in the third box.

Given: x = 24, k = 12

Find: y = ?

Formula:

y =  \frac{k}{x}

Solution:

y =  \frac{k}{x}  \\ y =   \frac{12}{24} \\ y =  \frac{1}{2} \\\boxed{y = 0.5}
