Ask questions in the comment section if you have questions. I'm happy to help! <3

Step-by-step explanation:

What the question is telling you is that x and y and proportional, almost like a ratio.

<h2>x : y</h2><h2>-3 : 6</h2>

Now we have to find y when x is four.

<h2>-3 : 6</h2><h3>     to </h3><h2> 4 : y</h2><h2 />

Let's create a proportional equation...

<h3>(-3 / 6) = 4 / y</h3><h3>- 1 / 2 = 4 / y</h3>

What can we divide by four to create -1/2?

<h2>y = -8.</h2>

If n =270 and (p-hat) =0.43, find the margin of error at a 99% confidence level.. give answer to 3 decimals
Troyanec [42]

Answer:

0.078

Step-by-step explanation:

Margin of error = z√(p(1-p)/n)

Given

p-hat = 0.43

n = 270

z at 99% confidence interval = 2.576

Substitute

MOE = 2.576√0.43(1-0.43)/270

MOE = 2.576√0.43*0.57/270

MOE = 2.576√0.2451/270

MOE = 2.576*0.030129

MOE = 0.078

Hence the margin og error is 0.078
