Answer:
The expected value of playing the game is $0.75.
Step-by-step explanation:
The expected value of a random variable is the weighted average of the random variable.
The formula to compute the expected value of a random variable <em>X</em> is:

The random variable <em>X</em> in this case can be defined as the amount won in playing the game.
The probability distribution of <em>X</em> is as follows:
Number on spinner: 1 2 3 4 5 6
Amount earned (<em>X</em>): $1 $4 $7 $10 -$8.75 -$8.75
Probability: 1/6 1/6 1/6 1/6 1/6 1/6
Compute the expected value of <em>X</em> as follows:





Thus, the expected value of playing the game is $0.75.
What is the actual question? If it is asking what the rate represents, it represents speed since speed since speed is the rate of change of distance over a period of time.

<span>How many ounces are in 2 1/2 pounds .( 16 ounces =1 pound )
Convert 2 1/2 to improper fraction
1 = 2/2
2 1/2 = 5/2
Next, multiply 16 with 5/2
16 x 5 = 80
Divide 80 with 2
80/2 = 40
40 oz is your answer
