Your school’s baseball team sells 1250 raffle tickets at $4 each. The grand prize is a $3000 boat. The second prize is a $450 gr
densk [106]

Answer:

The expected value of the winnings for a single-ticket purchase is -$1.0016.

Step-by-step explanation:

The total number of tickets sold is, <em>N</em> = 1250.

Cost of one ticket is, $4.

Let <em>X</em> = amount of prize.

The prize distribution is as follows:

1 Grand price = $3000

1 Second prize = $450

10 Third prize = $25

The expected value <em>X</em> can be computed using the formula:

E(X)=\sum x.P(X)

Compute the probability distribution of <em>X</em> as follows:

     Prize        Amount (X)         P (X)                    x · P (X)

1 Grand prize    $3000         \frac{1}{1250}=0.0008     \$3000\times 0.0008=2.4

1 Second prize  $450          \frac{1}{1249}=0.0008      \$450\times 0.0008=0.36

10 Third prize      $25          \frac{10}{1248}=0.008        \$25\times 0.008=0.2

No prize             -$4      1-\sum P(Win)\\=0.9904   -\$4\times 0.9904=-3.9616

TOTAL                              1.0000                            -1.0016

Thus, the expected value of the winnings for a single-ticket purchase is -$1.0016.

Solve for x. (1 point) −3x + 2b &gt; 8 x &lt; the quantity negative 2 times b plus 8 all over negative 3 x &gt; the quantity neg
masha68 [24]

Given:

-3x+2b>8

To find:

The value of x.

Solution:

We have,

-3x+2b>8

To find the value of x, we need to isolate x on one side.

Subtract 2b from both sides.

-3x>8-2b

Divide both sides by -3. On multiplying or dividing an inequality by a negative number, we need to change the sign of inequality.

\dfrac{-3x}{-3}

x

The required inequality for x is x.

Therefore, the correct option is A.
