1 answer:
Step-by-step explanation:
x +
x + x - 1
—————————--------------
x
Simplify
(((3 • (x3)) + 5x) - ) + 1
3.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using x as the denominator :
3x^3 + 5x (3x^3 + 5x) • x
3x^3 + 5x = ———————— = ——————————————
1 x
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
4.1 Pull out like factors :
+ 5x
x}{x}[/tex]
5.1 Adding a whole to a fraction
Rewrite the whole as a fraction using x as the denominator :
1 1 • x
1 = — = —————
1 x

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.
