Answer:
0.1349
Step-by-step explanation:
Given that:
Sample size, n = 500
20% of 500 ; 0.2 * 500 = 100
p = 0.18 ; n = 500 ; 1 - p = 0.82
P(x ≥ 100) ;
Using the binomial probability relation :
P(x =x) = nCx * p(x)^x * (1 - p)^(n - x
P(x ≥ 100) = 500C100 * 0.18^100 * 0.82^400
P(x ≥ 100) = 0.1349

Answer:
x = -11
Step-by-step explanation:
Convert fraction into negative exponential form: ![(36^-^1)^x^-^4=(216^-^1)^x^+^1\\](https://tex.z-dn.net/?f=%2836%5E-%5E1%29%5Ex%5E-%5E4%3D%28216%5E-%5E1%29%5Ex%5E%2B%5E1%5C%5C)
Simplify using exponent power rule: ![(a^n)^m=a^n^m:36^-^x^+^4=216^-^x^-^1](https://tex.z-dn.net/?f=%28a%5En%29%5Em%3Da%5En%5Em%3A36%5E-%5Ex%5E%2B%5E4%3D216%5E-%5Ex%5E-%5E1)
Convert both sides of the equation into terms with same base:![(6^2)^-^x^+^4=(6^3)^-^x^-^1](https://tex.z-dn.net/?f=%286%5E2%29%5E-%5Ex%5E%2B%5E4%3D%286%5E3%29%5E-%5Ex%5E-%5E1)
Simplify using exponent power rule:
![(a^n)^m=a^n^m:6^-^2^x^+^8=6^-^3^x^-^3](https://tex.z-dn.net/?f=%28a%5En%29%5Em%3Da%5En%5Em%3A6%5E-%5E2%5Ex%5E%2B%5E8%3D6%5E-%5E3%5Ex%5E-%5E3)
Based on the given conditions, corresponding exponents are equal:
![-2x=8=-3x-3](https://tex.z-dn.net/?f=-2x%3D8%3D-3x-3)
Rearrange unknown terms to the left side of the equation:
![-2x+3x=-3-8](https://tex.z-dn.net/?f=-2x%2B3x%3D-3-8)
Combine like terms: ![x=-3-8](https://tex.z-dn.net/?f=x%3D-3-8)
Calculate the sum or difference: ![x = -11](https://tex.z-dn.net/?f=x%20%3D%20-11)
Thurs, x = -11

Sale price = overall price for something
EX:
Shoes: $75.24
Tax (florida) 7%
7 turns to .07
.07 * 75.24 = 5.2668
round to nearest tenth
5.30
add this amount to total amount
75.24 + 5.30 = 80.54
And der u go
