Answer:
$0.558
Step-by-step explanation:
The expected value is the sum of the value of each outcome times the chance that it happens. In this case, there are two outcomes:
- Win $31 million
- Win $0
Then our expected value can be calculated as:
Answer:
114 Square Meters
Step-by-step explanation:
To find the area of a rectangle you multiply the base by the height.
19 x 6 =114
Therefore the answer is 114 square meters
8000/ 2 = x/16
cross multiply
2x = 8000 * 16
2x = 128000
x = 128000/2
x = 64000 crocus flowers
Answer:
69
Step-by-step explanation:
both edges equal 90 degrees
90 plus 90 plus 111 =291
360-291
2x - y = -24
x + 7y = 3
Solve one equation for a variable and plug the resulting value into the second equation.
x + 7y = 3 Subtract 7y from both sides
x = -7y + 3
Now, plug that x-value into the x of the first equation.
2x - y = -24 Plug in the x-value
2(-7y + 3) - y = 24 Use the Distributive Property
-14y + 6 - y = -24 Combine like terms (-14y and -y)
-15y + 6 = -24 Subtract 6 from both sides
-15y = -30 Divide both sides by 15
y = 2
Next, plug the y-value back into the second equation.
x + 7y = 3 Plug in the y-value
x + 7(2) = 3 Multiply
x + 14 = 3 Subtract 14 from both sides
x = -11
y = 2 and x = -11
