In the game of roulette, a player can place a $ bet on the number and have a probability of winning. If the metal ball lands on , the player gets to keep the $ paid to play the game and the player is awarded an additional $. Otherwise, the player is awarded nothing and the casino takes the player's $. What is the expected value of the game to the player? If you played the game 1000 times, how much would you expect to lose?
Complete Question
The complete question is shown on the first uploaded image
Answer:
a
The expected amount to be lost is 0.5263 cents per game
b
The expected amount to be lost is
[tex]P = \$ 526 .3 [/tex]
Step-by-step explanation:
From the question we are told that
The probability of winning is [tex]p = \frac{1}{38} = 0.0263[/tex]
Generally the probability of losing is mathematically evaluated as
[tex]q = 1-p [/tex]
=> [tex]q = 1-0.0263 [/tex]
=> [tex]q = 0.9737[/tex]
Generally the expected value is mathematically represented as
[tex]E(X) = \sum x_i * P(x_i)[/tex]
Here [tex]x_i[/tex] is a discrete variable (i.e it is a countable ) are outcomes of the player winning and the player losing
So
[tex]E(X) = x_1 * P(x_1) + x_2 * P(x_2) [/tex]
Now the outcome of winning is making $350 so
[tex]x_1 = \$ 350[/tex]
the outcome of losing is losing $10 so
[tex]x_2 = - \$10[/tex]
So
[tex]E(X) = 350* 0.0263 -10 * 0.9737 [/tex]
[tex]E(X) = -0.5263 [/tex]
hence the expected amount to be lost is 0.5263 cents per game
If you played the game 1000 times, the amount that is expected to be lost is
[tex]P = 1000 * -0.5263[/tex]
=> [tex]P = -\$ 526 .3 [/tex]
Hence the expected amount to be lost is
[tex]P = \$ 526 .3 [/tex]
Write a possible equation for a polynomial whose graph has horizontal intercepts at x = 2,-1,-3.
help
Answer:
y = (x - 2)(x + 1)(x + 3)
Step-by-step explanation:
horizontal intercepts at x = 2, -1, -3
-> y = 0 when x = 2, x = -1, and x = -3
Think x minus what equals y?
1. y is 0 and x is 2 -> 0 = (2 - 2) -> y = (x - 2)
2. y is 0 and x is -1 -> 0 = (-1 - (-1)) -> y = (x + 1)
3. y is 0 and x is -3 -> 0 = (-3 - (-3)) -> y = (x - 3)
so the equation is y = (x - 2)(x + 1)(x + 3)
since y = 0 when x = 2, x = -1, and x = -3
We want to find a polynomial given that we know its roots.
We will get:
p(x) = x^3 + 2*x^2 - 5*x - 6
-------------------------------------
A polynomial with the roots {x₁, x₂, ..., xₙ} and a leading coefficient A, we can write it as:
p(x) = A*(x - x₁)*(x - x₂)*...*(x - xₙ)
Here we know that the roots (horizontal intercepts) are {2, -1 , -3} but we do not know the leading coefficient, so we will use A = 1.
Then the polynomial is:
p(x) = (x - 2)*(x + 1)*(x + 3)
Expanding that we get:
p(x) = (x^2 - x - 2)*(x + 3)
p(x) = x^3 + 2*x^2 - 5*x - 6
This is a possible equation for the polynomial with the given horizontal intercepts.

Which of the following are ordered pairs for the equation y = 1/3x - 1?
(0,3) (0,-1) (6,1)
(3,0) (0,-1) (6,1)
(0,-1) (1,-4) (2,-7)
(0,-1) (-3,0) (-4,3)
Answer:
answer is the 2nd one
Step-by-step explanation:
y = 1/3(3) - 1 = 1 - 1 = 0 (3,0)
y = 1/3(0) - 1 = 0 - 1 = -1 (0, -1)
y= 1/3(6) - 1 = 2 - 1 = 1 (6, 1)
Cesars net worth is 8,250.63 his liabilities are 3,222.35 what is cesars assets
Given parameters:
Net worth of Cesar = 8250.63
Liabilities = 3222.35
Unknown:
Cesar's asset = ?
Solution:
A person's net worth is their Assets minus liability;
Net worth = Assets - Liabilities
Assets = Net worth + Liabilities
For Cesar;
Assets = 8250.63 + 3222.35 = 11472.98
Cesar's assets is 11472.98

3x + x- 2x + 8 = 3x + x
Answer:
x=4
Explanation:
3x+x−2x+8=3x+x
Step 1: Simplify both sides of the equation.
3x+x−2x+8=3x+x
3x+x+−2x+8=3x+x
(3x+x+−2x)+(8)=(3x+x)(Combine Like Terms)
2x+8=4x
2x+8=4x
Step 2: Subtract 4x from both sides.
2x+8−4x=4x−4x
−2x+8=0
Step 3: Subtract 8 from both sides.
−2x+8−8=0−8
−2x=−8
Step 4: Divide both sides by -2.
−2x−2=−8−2

Given parameters:
First term of the sequence = x
Second term = x + 2
Third term = x + 4
Sum of the first three terms = 72
Unknown:
First term of the sequence = ?

Frieda and three of her friends decide to go canoeing. They each rent a life preserver for $12.75. They split the cost of the canoe. If each person pays $23.75, how much did the canoe cost?
Answer:
The canoe cost $44
Step-by-step explanation:
There are 4 friends that went canoeing. Each one of them spent a total of $23.75 including $12.75 for the rent of a life preserver, and for one-fourth of the canoes cost, assuming they split the total cost of the canoe.
From the $23.75, we must subtract the $12.75 that the life preserver cost:
$23.75-$12.75 = $11
Those $11 were the individual contribution to the cost of the canoe. Since there were 4 friends, the canoe cost 4*$11 = $44
The canoe cost $44
