<span>The answer is that x = 21/9.

Start with the original: 4(2x - 1) - 7 = 4 - x + 6
Now distribute the 4:</span> <span> 8x - 4 - 7 = 4 - x + 6.
Now combine the like terms. 8x - 11 = -x + 10.
Now add x to both sides. 9x - 11 = 10.
Now add 11 to both sides. 9x = 21.
And divide by 9 on both side. x = 21/9. </span>

Answer:

$x=\frac{21}{9}$

Step-by-step explanation:

Given : Equation 4(2x - 1) - 7 = 4 - x + 6

We have to solve for x.

Consider the given equation

4(2x - 1) - 7 = 4 - x + 6

Apply distributive rule, $a(b+c)=ab+ac$ , we have,

8x - 4 -7 = 4 - x + 6

Simplify, by adding similar terms, we have,

8x - 11 = 10 - x

Adding x both side, we ave,

8x + x -11 = 10

Add 11 both side, we have,

9x = 10 + 11

9x = 21

Divide both side by 9, we get,

$x=\frac{21}{9}$

From the description we can infer that we have the expression: $41^{- \frac{2}{5} }$ .
Now, to write our expression as a as a root, we are going to apply the law of exponents: $x^{-n}= \frac{1}{x^n}$ first
$41^{- \frac{2}{5} }= \frac{1}{41^{ \frac{2}{5} }}$

Next, we are going to apply the law about fractional exponents: $x^{ \frac{m}{n}}= \sqrt[n]{x^m}$
$\frac{1}{41^{ \frac{2}{5} }}= \frac{1}{ \sqrt[5]{41^2} }$

We can conclude that the value of B is 2.

Answer:

the chance that the population mean will either be less than $1,500 or above $2,100 is 10%

Step-by-step explanation:

We are 90% confident that the true population mean willl be between $1,500 and $2,100

This means that there is a 90% probability that the true population mean will be between $1,500 and $2,100.

So 100-90 = 10% probability that it is outside of this interval, that is, either be less than $1,500 or above $2,100.

So the correct answer is:

the chance that the population mean will either be less than $1,500 or above $2,100 is 10%
