The correct answer is 20 Hope this helps! ;D
Answer:
a) - $0.169
b) - $0.04242
Step-by-step explanation:
Data provided in the question:
Bet amount = $4
Probability of losing $4 = 
Probability of gaining $4 = 
a) The expected value
= Winning amount × winning probability - Losing amount × Losing probability
= $4 × - $4 ×
= $4 × 
= - $0.169 (Negative sign means loss)
b) The amount lost for each dollar = 
= 
= - $0.04242

Answer:
1/10 as a percent is 10%
1/5 as a percent is 20%
Step-by-step explanation:
You need to multiply the bottom numbers to 100 because usually all percentages are out of 100. The result is the top number.
Answer: The solution is (3, -2)
This means that x = 3 and y = -2 pair up together.
=====================================================
Explanation:
The solution is where the two lines cross. Note if we started at the origin (0,0) and moved to the right 3 units, and then down 2 units, we would arrive at the location (3, -2).
-----------------
As a way to check, we can plug x = 3 into each equation. We should get y = -2 as a result for each equation
y = (-5/3)x + 3
y = (-5/3)*3 + 3
y = -5+3
y = -2
The first equation is confirmed. Let's check the second equation
y = (1/3)x - 3
y = (1/3)*3 - 3
y = 1 - 3
y = -2
Both equations have the y value equal -2 when x = 3. Therefore, the overall solution is confirmed.
