y = - 2x + 7; slope m = -2

Parallel lines, slope is the same

So y = -2x + b

b = y + 2x

Passing thru (4 , 1)

Plug in

b = 1 + 2(4)

b = 9

Equation

y = - 2x + 9

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).

Identify the quadrant where each point is located. (-5,2) (5,-5) (2,-5) (-4,-5)

Tanzania [10]

(-5,2) is located in the II quadrant because the x is negative and the y is positive.

(5,-5) is located in the IV quadrant because the x is positive and the y is negative.

(2,-5) is also located in the IV quadrant because the x is positive and the y is negative.

(-4,-5) is located in the III quadrant because both x and y are negative.
