3(m-2)=5(m-4)

3m-6=5m-20

3m-5m=-20+6

-2m=-14

-m=-7

m=7

I hope this is what you need..

Min knows that pi times radius equals 9.42 cm. What would she need to do to find the area?
Rus_ich [418]
\bf \textit{area of a circle}\\\\
A=\pi r^2\\\\
-------------------------------\\\\
\textit{now, we know that }\pi r=9.42\impliedby \textit{let's square both sides}
\\\\\\
(\pi r)^2=(9.42)^2\implies (\pi ^2r^2)=9.42^2\implies \pi \pi r^2=9.42^2
\\\\\\
\stackrel{area}{\pi r^2}~~=~~\cfrac{9.42^2}{\pi }

A political candidate has asked you to conduct a poll to determine what percentage of people support her. If the candidate only
Snezhnost [94]

Answer:

At sample size of 752 is needed.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

The margin of error is:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

90% confidence level

So \alpha = 0.1, z is the value of Z that has a pvalue of 1 - \frac{0.1}{2} = 0.95, so Z = 1.645.

What size of sample is needed?

A sample size of n is needed.

n is found when M = 0.03.

We do not have a estimate for the true proportion, so we use \pi = 0.5, which is when we are going to need the largest sample size.

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

0.03 = 1.645\sqrt{\frac{0.5*0.5}{n}}

0.03\sqrt{n} = 1.645*0.5

\sqrt{n} = \frac{1.645*0.5}{0.03}

(\sqrt{n})^{2} = (\frac{1.645*0.5}{0.03})^{2}

n = 751.67

Rounding up

At sample size of 752 is needed.
