Using shells, the volume is
![\displaystyle2\pi\int_0^6(6-x)x\,\mathrm dx](https://tex.z-dn.net/?f=%5Cdisplaystyle2%5Cpi%5Cint_0%5E6%286-x%29x%5C%2C%5Cmathrm%20dx)
where
![6-x](https://tex.z-dn.net/?f=6-x)
is the distance from any point in the region along the x-axis to the axis of revolution
![x=6](https://tex.z-dn.net/?f=x%3D6)
, which makes up the radius of each shell; and
![x](https://tex.z-dn.net/?f=x)
is the height of each shell, which is determined by the line
![y=x](https://tex.z-dn.net/?f=y%3Dx)
.
So the volume is
Answer: (0.685, 0.735)
Explanation:
First, we will compute the confidence level of the given:
![\text{ Confidence Level }=\frac{36}{40}\times100\%=90\%](https://tex.z-dn.net/?f=%5Ctext%7B%20Confidence%20Level%20%7D%3D%5Cfrac%7B36%7D%7B40%7D%5Ctimes100%5C%25%3D90%5C%25)
They gave us a margin of error of 0.025. From the given, we know that p=71%=0.71.
The confidence interval would then be:
![\begin{gathered} (p-E,p+E) \\ =(0.71-0.025,0.71+0.025) \\ =(0.685,0.735) \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%28p-E%2Cp%2BE%29%20%5C%5C%20%3D%280.71-0.025%2C0.71%2B0.025%29%20%5C%5C%20%3D%280.685%2C0.735%29%20%5Cend%7Bgathered%7D)
Therefore, the confidence interval would then be (0.685, 0.735)
-3x-8=10
First add 8 to both sides
-3x=18
Then divide both sides by -3
x=-6
