What does the central limit theorem tell us about the distribution of those mean​ ages?

<span>A.    </span>Because n>30, the sampling dist of the mean ages can be approximated by a normal dist with a mean u and a SD o/sqrt 54,

Whenever n<span>>30 the central limit theory applies.</span>

Solve for n 50 points <br><br> a=p(1+r/n)^rn
Andreyy89

Answer:

n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }

Step-by-step explanation:

a=p(1+\frac{r}{n} )^{nt}

\frac{a}{p} =(1+\frac{r}{n} )^{nt}

\sqrt[nt]{\frac{a}{p}}  =(1+\frac{r}{n} )

\sqrt[nt]{\frac{a}{p}} -1 =(\frac{r}{n} )

n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }

[ Do not confuse, as there are 2 n's, one in subject and another as power. We can never make the power or in a root, the subject. In order to solve for n, we have to make the character "n", the subject. ]
