Let x be the probability of winning and let y be the probability of losing. Then we can write the following equation:
2x - y = -0.65 ..............(1)
the sum of the probabilities of winning and losing must equal 1.
x + y = 1............(2)
Rearranging (2), gives:
y = 1 - x ............(3)
Plugging the expression for y from (3) into (1), we get:
2x - 1 + x = -0.65
which simplifies to:
3x = 0.35
Therefore x = 0.117 and y = 0.883.
The expected value of the game will be a loss of 65 cents if the probability of winning is 0.117 and the probability of losing is 0.883.
Answer:
1/2
Step-by-step explanation:
Using rise over run, you get 1/2. Hope this helps :), if you need the slope-intercept equation (y=mx+b), it's y=1/2x+0

Answer:
y
2
Step-by-step explanation:
1. switch sides
2. distribute
3. simply (combine like terms) in this case it would go to 22y
4. add 48 to both sides
5. simplify
6. divide
