A government official is in charge of allocating social programs throughout the city of Vancouver. He will decide where these so

otez555 [7]

Answer: (0.132132, 0.274368)

Step-by-step explanation:

Given : A simple random sample of 123 people living in Gastown and finds that 25 have an annual income that is below the poverty line.

i.e. n= 123

$\hat{p}=\dfrac{25}{123}\approx0.203252$

Critical value for 95% confidence interval : $z_{\alpha/2}=1.96$

Confidence interval for population :

$\hat{p}\pm z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

i.e. $0.203252\pm (1.96)\sqrt{\dfrac{0.203252(1-0.203252)}{123}}$

$0.203252\pm (1.96)\sqrt{\dfrac{0.203252(1-0.203252)}{123}}\\\\\0.203252\pm0.071118\\\\=(0.20325-0.071118,\ 0.203252+0.071118)\\\\=(0.132132,\ 0.274368)$

Hence, the 95% confidence interval for the true proportion of Gastown residents living below the poverty line : (0.132132, 0.274368)

Find an equation for the surface consisting of all points p for which the distance from p to the x-axis is 5 times the distance

guajiro [1.7K]

Distance from P to the x-axis = 2x distance from P to the yz-plane

Distance to the x-axis of a point P=(x,y,z) is (y^2+z^2)^1/2 
Distance to the yz-plane of a point P=(x,y,z) is x 

So your equation is: 
(y^2+z^2)^1/2 = 2x 
=> y^2 + z^2 = 4x^2 
=> y^2 + z^2 - 4x^2 = 0

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
