Find an equation for the line that passes through the points (3,-4) and (-1,6)

Sladkaya [172]

Answer:

y+4=-5/2(x-3)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(6-(-4))/(-1-3)

m=(6+4)/-4

m=10/-4

m=-5/2

y-y1=m(x-x1)

y-(-4)=-5/2(x-3)

y+4=-5/2(x-3)

A survey of households in a small town showed that in 850 of 1,200 sampled households, at least one member attended a town meeti

Iteru [2.4K]

Answer:

Hence the confidence interval is ( 0.6745, 0.7422).

Step-by-step explanation:

Now the given are

Sample size = n = 1200

x = 850

Sample proportion is

$\hat{p}=\frac{x}{n}=\frac{850}{1200}=0.7083$

We have to construct 99% confidence interval for the population proportion.

Formula Used:

$(\hat{p}-E , \hat{p}+E)$

Here E is a margin of error.

$E =Zc\times\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}$

Zc = 2.58

$E =2.58\times\sqrt{\frac{0.7083*(1-0.7083)}{1200}}\\\\E=2.58\times\sqrt{0.000172}=0.0339$

So confidence interval is ( 0.7083 - 0.0339 , 0.7083 + 0.0339)

= ( 0.6745 , 0.7422).
