Rationalize the denominator of the following expression and simplify:

Mama L [17]

To "rationalize the denominator" is another way to say, getting rid of that pesky radical at the bottom.

we'll simply start by multiplying top and bottom by the "conjugate" of the denominator, recall difference of squares, anyhow, let's do so

$\bf \cfrac{6+\sqrt{2}}{5-\sqrt{2}}\cdot \cfrac{5+\sqrt{2}}{5+\sqrt{2}}\implies \cfrac{(6+\sqrt{2})(5+\sqrt{2})}{(5-\sqrt{2})(5+\sqrt{2})}\implies \cfrac{(6+\sqrt{2})(5+\sqrt{2})}{5^2-(\sqrt{2})^2}
\\\\\\
\cfrac{30+6\sqrt{2}+5\sqrt{2}+(\sqrt{2})^2}{25-2}\implies \cfrac{30+11\sqrt{2}+2}{23}\implies \cfrac{32+11\sqrt{2}}{23}$

(b) Graph the equation x – 2y = 3

arsen [322]

Answer:

Please look at the image below.

Step-by-step explanation:

If you fix this equation into the y-intercept form(y=mx+c), it will become:

-2y=-x+3

y=x/2-3/2

Looking at this, x/2 is the slope, and -3/2 is the y-intercept.

Hope this helps!!!!

State, and briefly explain, whether the width of a confidence interval for one population proportion would decrease, increase, o

Semenov [28]

Answer:

<h3>The option b) is correct</h3><h3>The width of a confidence interval for one population proportion would decrease, increase, or remain the same as a result is <u>Increase the value of the sample mean (0.5 point) </u></h3>

Step-by-step explanation:

Given that the width of a confidence interval for one population proportion would decrease, increase, or remains the same.

<h3>To find the result for the given data :</h3>

By definition we have that "the width for the confidence interval decreases as the sample size increases". The width of the confidence interval increases as same as the standard deviation also increases. The width increases as the confidence level increases between (0.5 towards 0.99999 - stronger).

The width of a confidence interval is affected by 3 measures. they are the value of the multiplier t* , the standard deviation s of the original data, and the sample size of n .

<h3>Therefore the width of a confidence interval for one population proportion would decrease, increase, or remain the same as a result is <u>Increase the value of the sample mean (0.5 point) </u></h3><h3>Therefore the option b) is correct</h3>
