Select the correct answer.

Answer:

A. The graph is a line that goes through the points (9,0) and (0,6).

Step-by-step explanation:

Given

$4x + 6y = 36$

Required

Select the true options

$(a)\ (9,0)\ and\ (0,6)$

This implies that"

$(x_1,y_1)= (9,0)$

$(x_2,y_2)= (0,6)$

So, we have: $(x_1,y_1)= (9,0)$

$4x + 6y = 36$

$4 * 9 + 6 * 0 = 36 + 0 = 36$

So, we have: $(x_2,y_2)= (0,6)$

$4 * 0 + 6 * 6 = 0 + 36 = 36$

<em>Hence (a) is true.</em>

Answer:

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

⇒ $=0.9738 - 0.0262$

⇒ $=0.9476$
