Answer:

r = 0.8 of geometric series.

Step-by-step explanation:

Given : geometric series (1.3)( $0.8^{n-1}$ .

To find : What is the value of r of the geometric series

Solution : We have given that (1.3) $0.8^{n-1}$ .

By geometric series formula $a_{n}$ = $a_{1}r^{n-1}$ .

On comparison

$a_{1}$ = 1.3

r = 0.8

Therefore, r = 0.8 of geometric series.

Answer:

The appropriate response is "0.9476".

Step-by-step explanation:

The given values are:

Standard deviation,

$\sigma=1150$

Randomly selected railroad-car shipments,

n = 500

As we know,

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

On substituting the values, we get

⇒ $=\frac{1150}{\sqrt{500} }$

then,

⇒ $=P(-1.94$

⇒ $=P(Z$

On using the table of P, we get

⇒ $=0.9738 - 0.0262$

⇒ $=0.9476$
