|x| means absolute value.
17-8=9. the absolute value of 9 is 9. (thats why all the negative answers are wrong)
Answer:
42
Step-by-step explanation:
Let that number be x
x is multiplied by 0.5, 1/3, then squared
(0.5/3 x)^2
Add 1: (0.5/3 x)^2 +1
Make it equal to 50
: (0.5/3 x)^2 +1 = 50 now solve
(0.5/3 x)^2 =50-1
(0.5/3 x)^2 =49
square root both sides ending up with:
0.5/3 x=7
solve for x
x=42

Assuming the probability of a boy is 50%, then the probability of 5 boys is
(50%)(50%)(50%)(50%)(50%) = 3.125%.
(1/2)(1/2)(1/2)(1/2)(1/2) = 1/32

The expected value of the outcome of the bid is $0.18
So let's start by counting how many bids are placed up to a total of 160.
100*160 = 16000.
What will be your arbitrary bid? As each bid has an equal chance of success, the average of all bids is used. (One cent plus 160 dollars) / 2 = 80 dollars (rounded)
Your odds of winning are 1/16000 (1 bid out of 16000).
If you win, your profit is 1920 ($2000 minus $80.00).
1920/16000 is $0.12
Your cost to enter the auction is $1, and your average winning offer is $0.12.
The result is $0.18 (0.12-1=-0.88).
Thus the expected value of the outcome of the bid is $0.18
