Okay. 10^12 is 1 trillion. 1 trillion * 7 is 7 trillion. 14 trillion / 7 trillion is 2. The national debt in 2010 is two times larger than in 2003. So that basically means that the national debt doubled from 2003 to 2010.
1) Before tax = $249.99
100% = 1 = 249.99
4% = 0.04
100% + 4% = 104% = 1.04 multiplier
1.04 x $249.99 = $259.9896 = $259.99 After Tax
2) After tax = $249.99
100% = 1
4% = 0.04
1 + 0.04 = 1.04
104% = $249.99
$249.99 / 1.04 = $240.375 = $240.38 Before Tax
Undistribute x
x(m+2n)=p
divide both sides by m+2n
x=
Answer:
1329.85≤μ≤1330.14
Step-by-step explanation:
z score for 99% confidence interval
from the z table we can find that the score for 99% confidence is 2.58
formula
z=![\frac{x-μ}{[tex]\frac{{σ}[tex]\sqrt{n}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-%CE%BC%7D%7B%5Btex%5D%5Cfrac%7B%7B%CF%83%7D%5Btex%5D%5Csqrt%7Bn%7D)
}[/tex]}[/tex]
where
x-sample mean
μ-population mean
σ-population standard deviation
n-sample size
2.58=![\frac{1330-μ}{[tex]\frac{{442}[tex]\sqrt{24}](https://tex.z-dn.net/?f=%5Cfrac%7B1330-%CE%BC%7D%7B%5Btex%5D%5Cfrac%7B%7B442%7D%5Btex%5D%5Csqrt%7B24%7D)
}[/tex]}[/tex]
1330-2.58×24÷442≤μ≤1330+2.58×24÷442
1329.85≤μ≤1330.14
