Answer:
2nd one: AB = 6
Step-by-step explanation:
Because PQ is 4 (Pythagorean triples), you can prove that triangle PBQ is congruent to PAQ by HL. You can then say AQ is equal to 3 becasue of CPCTC. AQ+QB=AB, or 3+3=6. AB=6
Answer: 0.0158
Step-by-step explanation:
Given : The data for the United States is that out of 1,000 sampled, 470 indicated yes, they felt political news was reported fairly.
According to the given information we have,
Sample size : n= 1000
Sample proportion: ![\hat{p}=\dfrac{470}{1000}=0.47](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%3D%5Cdfrac%7B470%7D%7B1000%7D%3D0.47)
The standard error for proportion is given by :-
![S.E.=\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}](https://tex.z-dn.net/?f=S.E.%3D%5Csqrt%7B%5Cdfrac%7B%5Chat%7Bp%7D%281-%5Chat%7Bp%7D%29%7D%7Bn%7D%7D)
![S.E.=\sqrt{\dfrac{0.47(1-0.47)}{1000}}](https://tex.z-dn.net/?f=S.E.%3D%5Csqrt%7B%5Cdfrac%7B0.47%281-0.47%29%7D%7B1000%7D%7D)
![S.E.=\sqrt{0.0002491}](https://tex.z-dn.net/?f=S.E.%3D%5Csqrt%7B0.0002491%7D)
![S.E.=0.0157829021412\approx0.0158](https://tex.z-dn.net/?f=S.E.%3D0.0157829021412%5Capprox0.0158)
[Rounded to the nearest four decimal places.]
Hence, the standard error for the confidence interval = 0.0158

Answer:
(-5, 5), (2, 8), (-6, 0)
Step-by-step explanation:
It is convenient to graph the solution, then plot the points to see which fall in the solution area.
The point (3, 9) falls on the boundary line, which is <em>not</em> part of the solution set.
The points that are solutions are ...
B(-5, 5)
E(2, 8)
F(-6, 0)
