Answer:

SAS Postulate

Step-by-step explanation:

Yes, you have chosen the correct answer, it should be SAS postulate, because from figure, we know that we have 2 sides of triangles and its one angle as equal.

So it would be efficient to use SAS postulate, as we have parameters to prove this true using this postulate.

The height distribution of NBA players follows a normal distribution with a mean of 79 inches and standard deviation of 3.5 inch

Shtirlitz [24]

Answer:

The probability will be "0.0111".

Step-by-step explanation:

The given values are:

Mean,

$\mu$ = 79

Standard deviation,

$\sigma$ = 3.5

Now,

⇒ $\sigma\bar x = \frac{\sigma}{\sqrt n}$

$= \frac{3.5}{\sqrt 16}$

$=0.875$

⇒ $P(\bar x > 81) = 1 - P(\bar x < 81)$

So,

= $1 - P{\frac{(\bar x - \mu \bar x )}{ \sigma \bar x} < \frac{(81 - 79) }{0.875} ]$

= $1 - P(z < 2.2857)$

= $0.0111$

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. ]
