Answer:
y= x⁴ -21x²-100
combine x's I think
x⁴= 1x? cuz if it's 1x⁴ that's 1x*1x*1x*1x = 1x
1x * -21x²
-21x * -21x = 441x
+1x = 442x
y= 442x -100
I'm not sure if I did that right

Answer:
10.2 ft
Step-by-step explanation:
[tex]a^{2} +b^{2} = c^{2} \\8^{2} +b^{2} =13^{2} \\[/tex]
64 + [tex]b^{2}[/tex] = 169

A department store buys 400 shirts at a cost of $9,600 and sells them at a selling price of $30 each.
Find the percent markup.
The percent markup is
%. (Round to the nearest whole number as needed.)
Answer:
The percent markup is 25%.
Step-by-step explanation:
Percent markup:
The percent markup is given by the difference in selling price and buying price multiplied by 100% and divided by the buying price.
A department store buys 400 shirts at a cost of $9,600
This means that the buying price is:
$9600/400 = $24
Find the percent markup.
Buying price: $24
Selling price: $30
30 - 24 = 6
6*100%/24 = 25%
The percent markup is 25%.

At a casino, people line up to pay $20 each to be a contestant in the follow- ing game: The contestant flips a fair coin repeatedly. If she flips heads 20 times in 20 mil a row, she walks away with lion dollars; otherwise she walks away with R 0 dollars
(a) Find the PMF of R, the reward earned by the contestant.
(b) The casino counts "losing contestants who fail to win the 20 million dollar prize. Let L equal the number of los- ing contestants before the first winning contestant. What is the PMF of L?
(c) Why does the casino offer this game?
Answer:
a)
P ( R = 20 million ) = 0.00000095367
P ( R = 0 million ) i.e. not winning = 0.99999904633
b) P ( L ) = ( 1 - p )^l * p
C)The casino offer the game because the expected revenue exceeds the winning
Step-by-step explanation:
P( winning ) = P ( getting 20heads in a row ) = 0.5^20 = 0.00000095367
a) PMF of R
P ( R = 20 million ) = 0.00000095367
P ( R = 0 million ) i.e. not winning = 0.99999904633
b) what is the PMF of L
L = number of loosing clients before winning
P( L = 0 ) = P i.e. if first contestant wins, if the second contestant win, L=1 repeat same process continuously
P ( L = 2 ) = ( 1 - p)^2 p
Hence the PMF of L
P ( L ) = ( 1 - p )^l * p where p = 0.5^20
C) The casino offer the game because the expected revenue exceeds the winning
we can prove this using the relation below
E( L ) = ( 1 - P ) / 1 - ( 1 - P )
= 1 / P - 1
where p = 0.00000095367 ( probability of winning )
Hence E ( L ) = 1048575
hence expected revenue before someone wins
= (1048575 + 1 ) * 20 = $20,971,520
