Answer: (0.25,0.33)
Step-by-step explanation:
A 99% confidence interval for population proportion is given by:-
, where
= sample proportion,
= sample size.
Given: ![n=1025, \hat{p}=0.29](https://tex.z-dn.net/?f=n%3D1025%2C%20%5Chat%7Bp%7D%3D0.29)
A 99% confidence interval estimate of the proportion of adults who use the Internet for shopping:
![0.29\pm 2.576\sqrt{\dfrac{0.29(1-0.29)}{1025}}\\\\=0.29\pm 2.576\sqrt{0.00020087804878}\\\\=0.29\pm2.576(0.01417)\\\\=0.29\pm0.03650192\\\\=(0.29-0.03650192,\ 0.29+0.03650192)\\\\=(0.25349808,\ 0.32650192)](https://tex.z-dn.net/?f=0.29%5Cpm%202.576%5Csqrt%7B%5Cdfrac%7B0.29%281-0.29%29%7D%7B1025%7D%7D%5C%5C%5C%5C%3D0.29%5Cpm%202.576%5Csqrt%7B0.00020087804878%7D%5C%5C%5C%5C%3D0.29%5Cpm2.576%280.01417%29%5C%5C%5C%5C%3D0.29%5Cpm0.03650192%5C%5C%5C%5C%3D%280.29-0.03650192%2C%5C%200.29%2B0.03650192%29%5C%5C%5C%5C%3D%280.25349808%2C%5C%200.32650192%29)
![\approx(0.25,\ 0.33)](https://tex.z-dn.net/?f=%5Capprox%280.25%2C%5C%200.33%29)
Thus, a 99% confidence interval estimate of the proportion of adults who use the Internet for shopping = (0.25,0.33)
1) -3x -3 -7x = 17
• start by grouping so add -3x and -7x which gives you -10x
• 10x -3 (+3) = 17 +3 = 20 add 3 on both sides)
• 10x (/10) = 20/ 10 = 2
1) x = 2
2) 10x -6 (+6) = 24 + 6 = 30
• 10x (/10) = 30/ 10 = 3
2) x = 3
3) -4 (+4) -5x = -39 +4 = -35
• -5x (/-5) = -35/ -5 = 7
3) x = 7
4) 3x - 5 > 10
this one i don’t understand, is there a typo maybe ?
5) -5x + x + 16 = -3 you can put a 1 to hold the place of x to make it 1x
• (-5x + 1x) + 16 = -3
• -4x + 16 (-16) = -3 -16 = -19
• -4x (/-4) = -19/ -4 = 4.75 or 4 3/4
5) x = 4.75

Answer:
Step-by-step explanation:
so let’s say x is the length. Then the width will be 3x-4. You add them together and multiply by two. The perimeter is 72 so the equation equala 72.
Equation:
(x+3x-4)*2=72
(4x-4)*2=72
8x-8=72
8x=80
x=10
length:10
width:26
