Answer:

The number is -3

Step-by-step explanation:

First, let's translate the statement into an equation.

4x = 2x - 6

Step 1: Subtract 2x from both sides.

$4x-2x=2x-6-2x$
$2x=-6$

Step 2: Divide both sides by 2.

$2x/2 = -6/2$
$x=-3$

Therefore, the number is -3/

what is the measure of the central angle of a circle with a radius 24 ft that intercepts at 10 ft arc? use 3.14 as pie

Brrunno [24]

Answer:

central angle =23.88°

Step-by-step explanation:

Given:Arc length =10ft

radius= 24ft

To find : central angle

Formula: Arc length = 2πr. $\frac{\theta}{360}$ °

⇒ ${\theta}$ = $\frac{arc length.360}{2{\pi}{r}}$

⇒ ${\theta}$ = $\frac{10(360{\degree})}{2 (3.14)(24)}$

⇒ ${\theta}=$ 23.8853503°

A production manager at a wall clock company wants to test their new wall clocks. The designer claims they have a mean life of 1

TEA [102]

Answer:

The correct answer will be "0.3043".

Step-by-step explanation:

The given values are:

$\mu = 15$

$n=41$

$\sigma^2=25$

then,

$\sigma=5$

If researchers know representative sample n > 30 and default deviation those who use z-test

∴ $P(x>15.4)$

⇒ $1-P(x$

⇒ $1-P(\frac{x-\mu}{\frac{\sigma}{\sqrt{n} } }$

⇒ $1-P(Z$

⇒ $1-0.695762$

⇒ $0.3043$
