Answer: b
Step-by-step explanation:
Answer: if 1 represents the game at the top and 7 the game at the bottom, the order is 1, 6, 5, 2, 3, 7, 4
Step-by-step explanation:
in a game where the expected value is zero, if your probability to win is p and the entry cost is C, then you should win an amount W = C/p
then p = C/W
1) C = $5, W = $200
p = 5/200 = 0.025
2) C = $6, W = $300
p = 6/300 = 0.02
3) C = $9, W = $468
p = 9/468 = 0.019
4) C = $8, W = $440
´p = 8/440 = 0.0181
5) C = $7, W = $315
p = 7/315 = 0.0022
6) C = $4, W = $168
p= 4/168 = 0.024
7) C = $10, W = $540
p = 10/540 = 0.0185
Then the order, from least probability to greatest probability of winning is:
1, 6, 5, 2, 3, 7, 4
Answer:
- 5/6
- 1/3
Step-by-step explanation:
The opooste angles are equal
so
4y-8=79+y
minus y both sides
3y-8=79
add 8 both sides
3y=87
diide both sides by 3
y=29
Answer:
6.46
Step-by-step explanation:
h(t) = (1/2)
+ v0t + h0
Origin is at surface of water (h = 0), up is positive.
a = -g = -9.8 m/
v0 = 25 m/s
h0 = 50 m
h(t) = -4.9t2 + 25t + 50
Find t when
7 = 
+ 25t + 50
- 25t - 43 = 0
t = [1/(2*4.9)] [25 ±√(
+ 4*4.9*43)]
t = (0.102)(25 ± 38.312)
t > 0 ⇒ use only the positive square root
t = (0.102)(25 + 38.312) ≅ 6.46 s
It is 7m above the water at about 6.46 s
