16-2n-5+8n=65 <br> Can you help me solve this please and show work as well?
lukranit [14]
<em>∙•❁ </em>Okay time to solve this Step-By-Step.<em>❁•∙ </em>

16−<span>2n</span>−5+<span>8n</span>=<span>65

<em>∙•❁ </em>So the first part we need to Simplify both sides of this equation, so:

<span><span><span><span>16−<span>2n</span></span>−5</span>+<span>8n</span></span>=65

<em>∙•❁ </em>We are going to simplify this Step-By-Step.

<span><span><span><span>16−<span>2n</span></span>−5</span>+<span>8n</span></span>=65

</span><span><span><span><span><span><span>16+</span>−<span>2n</span></span>+</span>−5</span>+<span>8n</span></span>=65

<em>∙•❁ </em>Combine like terms:
</span><span><span><span><span>
(<span><span>−2n</span>+8n</span>)</span>+<span>(<span>16+−5</span>)</span></span>=65 </span>

<span><span>6n+11</span>=65

</span><span><span><span>6n</span>+11</span>=65

<em>∙•❁ </em>Now subtract 11 from both sides.

<span><span><span><span>6n</span>+11</span>−11</span>=<span>65−11

</span></span><span><span>6n</span>=54

<em>∙•❁ </em>Now divide both sides by 6 and you'll get your answer:

6n/6=54/6

<em>∙•❁ </em>Your final answer is:

n=9

<em>∙•❁I hope this helps!❁•∙ </em> </span></span></span></span></span>

The National Center for Educational Statistics surveyed 5400 college graduates about the lengths of time required to earn their
fenix001 [56]

Answer:

The 90% confidence interval for the mean time required by all college graduates is between 5.36 years and 5.44 years.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.9}{2} = 0.05

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.05 = 0.95, so z = 1.645

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.645*\frac{1.9}{\sqrt{4500}} = 0.04

The lower end of the interval is the sample mean subtracted by M. So it is 5.4 - 0.04 = 5.36 years.

The upper end of the interval is the sample mean added to M. So it is 5.4 + 0.04 = 5.44 years.

The 90% confidence interval for the mean time required by all college graduates is between 5.36 years and 5.44 years.
