Step-by-step explanation:
Given
Population Proportion
=![\frac{1600}{2000}](https://tex.z-dn.net/?f=%5Cfrac%7B1600%7D%7B2000%7D)
![\hat{P}=0.8](https://tex.z-dn.net/?f=%5Chat%7BP%7D%3D0.8)
Confidence level =95 %
For 95% confidence interval level is ![\hat{P} \pm \sqrt{\frac{\hat{P}\left ( 1-\hat{P}\right )}{n}}](https://tex.z-dn.net/?f=%5Chat%7BP%7D%20%5Cpm%20%5Csqrt%7B%5Cfrac%7B%5Chat%7BP%7D%5Cleft%20%28%201-%5Chat%7BP%7D%5Cright%20%29%7D%7Bn%7D%7D)
=![0.8\pm 1.96\sqrt{\frac{\hat{0.8}\left ( 1-\hat{0.8}\right )}{2000}}](https://tex.z-dn.net/?f=0.8%5Cpm%201.96%5Csqrt%7B%5Cfrac%7B%5Chat%7B0.8%7D%5Cleft%20%28%201-%5Chat%7B0.8%7D%5Cright%20%29%7D%7B2000%7D%7D)

The interval lies between ![\left ( 0.781,0.8175\right )](https://tex.z-dn.net/?f=%5Cleft%20%28%200.781%2C0.8175%5Cright%20%29)
Answer:
Width = 14 inches
Length = 42 inches
Step-by-step explanation:
Length = 3 x width Width = 1/3 x length
First, construct a equation first using one of my formula on the top:
Length = 3 x width
2y + 6 = 3 ( y - 4 ) Distribute 3 to the values inside the ( )
2y + 6 = 3y - 12 Subtract 2y on both sides so there is only one
variable on one side
6 = y -12 Add 12 on both sides
18 = y
Width = ( y - 4 ) in <u><em>OR </em></u> 18 - 4 or 14 inches
Length = ( 2y + 6 ) in <em><u>OR </u></em> 36 + 6 = 42 inches

Answer:
interchange the role of x and y
x=9y+5
x-5=9y
<u>x-5</u><u> </u>=y
9
so,f^-1(x)= <u>x-5</u>
