Step 1. Factor out common terms in the first two terms, then in the last two terms.

2x^2(x - 5) -5(x - 5)

Step 2. Factor out the common term x - 5

Answer:

The answer is "0.0764"

Step-by-step explanation:

Please find the complete question in the attached file.

$\to \mu = \$ \ 4064\\\\\to \sigma = \$ \ 460 \\\\\to \sigma \bar{x} = \frac{\sigma}{\sqrt{n}}\\\\$

$= \frac{460}{\sqrt{21}}\\\\ = \frac{460}{4.58257569}\\\\=100.3802$

$\to P(\bar{x}< \$ \ 3920) = \frac{P((\bar{x} - \mu \bar{x})}{\frac{\sigma \bar{x}$

$\to P(z < -1.43) = 0.0764 \\\\\to P(\bar{x}< \$ \ 3920) = 0.0764\\\\$

Urgent please help..

Answer:

x ≈ 13.5

Step-by-step explanation:

Using the sine rule in the triangle, then

$\frac{sin34}{x}$ = $\frac{sin27}{11}$ ( cross- multiply )

x × sin27° = 11 × sin34° ( divide both sides by sin27° )

x = $\frac{11sin34}{sin27}$ ≈ 13.5 ( to the nearest tenth )
