Expected Value: $ _____
Answer:
The answer is: expected value is -$0.88
Step-by-step explanation:
Given is, the he bidding starts at 1¢ and goes up 1¢ at a time. A television that is worth $2000 is won, on average, with a bid of $160. So, $160 in 1¢ steps means 16000 bids.
Therefore, a person invest $1 with a 1/16000 probability of a $2000 return.
Noe, the expected value will be =
= -1+0.125 = -0.875 ≈ -$0.88
Hence, the answer is -$0.88
B. 12. 56 meters
C. 6.28 meters
D. 18.84 meters
Answer:
x = 6
Step-by-step explanation:
The x-intercept of the equation is where the graph crosses the x-axis when y = 0. So, we simply plug in 0 for y:
2(0) - x = -6
0 - x = -6
-x = -6
x = 6
Alternatively, you can graph the equation into a graphing calc and analyze where the graph crosses the x-axis.
Answer:
product y ³ - 64 and a = 16.
Step-by-step explanation:
Given : (y — 4)(y² + 4y + 16) .
To find : Using the distributive property to find the product a polynomial of the form y³ + 4y² + ay – 4y² – ay – 64. What is the value of a in the polynomial?
Solution : We have given
(y — 4)(y² + 4y + 16) .
Distribute y over (y² + 4y + 16) and - 4 over (y² + 4y + 16).
y (y² + 4y + 16) - 4 (y² + 4y + 16).
y ³+ 4y² + 16 y - 4y² - 16y - 64.
This is in form of y³ + 4y² + ay – 4y² – ay – 64.
Here, a = 16.
Product : combine like terms
y ³+ 4y² - 4y² + 16y - 16y - 64.
y ³ - 64.
Therefore , product y ³ - 64 and a = 16.
