Combine all the like terms on one side:
 0.8x-4.3x+1.2x=7.7-3.2
-2.3x=4.5
Use the division property of equality. divide both sides by -2.3.
That leaves you with x=-1.96 (when rounded). exact: -1.95652

On the left side of the equation we have like terms so: -3.5x + 3.2 = -1.2x + 7.7
Add 3.5 to each side: 3.2 = 2.3x + 7.7
Subtract 7.7 from each side: -4.5 = 2.3x
Divide both sides by 2.3: -1.95652174 = x
Answer: -1.95652174

The world famous gambler from Philadelphia, Senor Rick, proposes the following game of chance. You roll a fair die. If you roll
Orlov [11]

Answer:

You lose $0.833 while Rick gains $0.833, and so Rick is not Loco

Step-by-step explanation:

There are six numbers on a dice. Thus, probability of rolling exactly one number = 1/6

Probability of rolling two is 2/6.

Rolling a 1 pays $25, and probability = 1/6

Rolling a 2 pays $5,and probability = 1/6

Rolling a 3 pays $0, and probability = 1/6

Rolling a 4 or 5 pays -$10, and probability = 2/6

Rolling a 6 pays -$15, and probability = 1/6

Thus,lets calculate the expected value;

EV = (25 × 1/6) + (5 × 1/6) + (0 × 1/6) + (-10 × 2/6) + (-15 × 1/6)

EV = - $0.833

This means you lose $0.833 while Rick gains $0.833, and so Rick is not Loco.
