Which statement below correctly depicts the expected value of a fair game?
E(X) = 0
E(X) = 1
E(X) > 0
E(X) >1
Answer:
e(x)=0 will be your answer
Step-by-step explanation:
First of all it is important to know about the fair game. A game is said to be fair if it has equal chances of winning for both the parties.
In Statistical terms, this can be said as expected value =0
If E(X) = 1 where X is from the player, then organizer of the game would have more chances of losing.
Similarly if E(X)>0where X is from the player, then organizer of the game would have more chances of losing.
Also if E(X)>1, where X is from the player, then organizer of the game would have more chances of losing.
Hence a fair game is one where
Answer: A. E(X) = 0

Brittany and four of her friends want to join a softball league. The league requires teams to have at least nine players, but teams cannot have more than eighteen players. In interval notation, how many more people can join Brittany's team?
The additional number of people is [4, 13]
How to determine the number of people?Brittany and four of her friends are five people.
So, we have:
n = 5
The conditions are given as
At least = 9At most = 18Let the additional number of people be x
So, we have the following inequalities
x + 5 ≥ 9 and x + 5 ≤ 18
Subtract 5 from both sides
x ≥ 4 and x ≤ 13
Express as interval notation
[4, 13]
Hence, the additional number of people is [4, 13]

find the inverse of
f(x) = -6xˆ2 + 24x - 100
Answer:
See below
Step-by-step explanation:
y = -6x^2 + 24x-100
solve for 'x'
y + 100 = -6x^2 + 24x = -6(x^2-4x) complete the square for x
(y+100) /(-6 ) = (x-2)^2 -4 add 4 to both sides
(y+100)/(-6) +4 = (x-2)^2 sqrt both sides
sqrt [ ( y+100)/(-6) + 4 ] + 2 = x change x and y
y = ± sqrt [ (x+100)/(-6) + 4 ] + 2 simplify (if needed)
y = ± sqrt( -x/6 -12.666) + 2
