kompoz [17]

Answer:

$\frac{-27}{x^{15}}=-\frac{27}{x^{15}}$

Step-by-step explanation:

<em>If you just want to simplify -27/x^15, it is not very difficult. Here is the simple way.</em>

<em />

Given the expression

$\frac{-27}{x^{15}}$

solving

$\frac{-27}{x^{15}}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}$

$=-\frac{27}{x^{15}}$

Therefore,

$\frac{-27}{x^{15}}=-\frac{27}{x^{15}}$

QveST [7]

Answer: z= -1.636

Step-by-step explanation:

When population standard deviation is known, then the test statistic is given by :-

$z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

, where $\overline{x}$ = sample mean, $\mu$ = population mean, n=sample size , $\sigma$ = standard deviation

As per given,

$z=\dfrac{55.82-56}{\dfrac{0.77}{\sqrt{49}}}\\\\ z=\dfrac{-0.18}{\dfrac{0.77}{7}}\\\\z=\dfrac{-0.18}{0.11}\\\\z=-1.636$

Hence, the e test statistic to see whether the candy bars are smaller than they are supposed to be : z= -1.636
