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:

(x + a)/(ax) = b/x
a= 2
b = 5
(x + 2) /(2x) = 5/x
cross multiply
x * (x+2) = (2x)*5
x^2 + 2x = 10x
x^2 - 8x = 0
x ( x -8) = 0
We get two solutions
x = 0, 8
the solution 0 is extraneous
the solution 8 is valid.
Answer:
x = 35°
Step-by-step explanation:
Same side interior angles are supplementary, or they add up to 180°. So write an equation:

Solve for x. Subtract 145 from both sides:

The value of x is 35°.

Step-by-step explanation:
The statement is 3 multiplied by 2/3. Here, the first no of 3 and the other one is 2/3.
It can be written as follows :

3 is present at the numerator as well as the denominator. It will cancel out.
So,
=2
So, 3 multiplied by 2/3 equals 2.
