1/2 each
They are doing an equal amount which is 2/4 each but when you simplify it is 1/2
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:
The first table
Step-by-step explanation: The x values don't repeat which makes it a function
Answer:
37.94
Step-by-step explanation:
not sure if this is what you need but if you use Pythagoras therom you should get there
a^2 + b^2= c^2
12^2+36^2=c^2
12^2+36^2= 1440
the square root of 1440 is 37.9433192
