Answer:
Expected value of the game: -$0.421
Expected loss in 1000 games: $421
Step-by-step explanation:
There are two possible outcomes for the event:
- There is a 1 in 38 chance of winning $280
- There is a 37 in 38 chance of losing $8
The expected value for a single game is:
The expected value of the game is -$0.421
In 1,000 plays, the expected loss is:
You would expect to lose $421.
Answer:
D
Step-by-step explanation:
This is because of the slope and amount of earnings Tatiana has.
Tatiana gets 26 dollars added to her earnings every 2 hours
Sample: 16 + 26 = 42
The 16 represents the number of earnings that Tatiana gets/earns for hour 0.
If we were to graph the earnings of Tatiana meaning her time represents X and the earnings represent Y. We could clearly see that Tatiana earns more money than Darryl.
(8x - 12) + 64 + 68 = 180
(A straight line equals to 180)
8x - 12 + 132 = 180
Combine liked terms
8x + 120 = 180
-120 on both sides
8x = 40
/8 on both sides
x = 5
(8x - 12)
8(5) - 12
40 - 12
28
(2x + 18)
2(5) + 18
10 + 18
28
Answer:
x = 5
F ( x ) = x³ + 3 x
Slope of a horizontal line is 0.
f ` ( x ) = 3 x² + 3
3 x² + 3 = 0
3 x² = - 3 / : 3
x² = - 1 , which give complex roots.
Answer: NONE
Answer:
240 peanuts
