In a clinical trial of a cholesterol drug, 321 subjects were given a placebo, and 7% of them developed headaches. For such ra

artcher [175]

Answer: The value of n is 321.

Step-by-step explanation:

Since we have given that

Sample size = 321

Percentage of them developed headaches = 7%

So, the value of p would be

$\dfrac{x}{n}=\dfrac{7}{100}=0.07$

Now, the value of q would be

$q=1-p\\\\q=1-0.07\\\\q=0.93$

And the mean for the number of subjects who develop headaches would be

$n=pq\\\\n=0.07\times 0.93\\\\n=0.0651$

and the standard deviation would be

$\sigma=\sqrt{npq}\\\\\sigma=\sqrt{321\times 0.07\times 0.93}\\\\\sigma=4.571$

Hence, the value of n is 321.

What is log(z^4/5) written in expanded form?

Ostrovityanka [42]

To get answer:

$\mathrm{Apply\:log\:rule}:\quad \log _c\left(\frac{a}{b}\right)=\log _c\left(a\right)-\log _c\left(b\right)\\\log _{10}\left(\frac{z^4}{5}\right)=\log _{10}\left(z^4\right)-\log _{10}\left(5\right)\\=\log _{10}\left(z^4\right)-\log _{10}\left(5\right)\\\mathrm{Simplify}\:\log _{10}\left(z^4\right)\\\log _{10}\left(z^4\right)\\\mathrm{Apply\:log\:rule\:}\log _a\left(x^b\right)=b\cdot \log _a\left(x\right),\:\quad \mathrm{\:assuming\:}x\:\ge \:0\\=4\log _{10}\left(z\right)\\$
