Find the equation of a line parallel to y=−2x+4 that contains the point (−2,−5). Write the equation in slope-intercept form.

Y=-2x-9, because the slope needs stay the same to be parallel and -2x-2 is 4 so to get -5 you have to subtract 9 from 4

The radius is 2 and area = r^2*pi so 4*pi gives you 12.56 so the exact answer would be 12.56 and the answer with pi would be 4 times 3.14!

Answer:

(0.2278, 0.3322)

Step-by-step explanation:

Given that out of 400 people 112 agree and 288 disagree

Proportion of people agreeing = $\frac{112}{400} =0.28$

$q=1-p =0.72\\se = \sqrt{\frac{pq}{n} } =0.03175$

For confidence interval 90% we have critical value as

1.645

Margin of error =1.645*SE

= $1.645(0.03175)\\= 0.0522$

Confidence interval $= (0.28-0.0522, 0.28+0.0522)\\= (0.2278, 0.3322)$
