-3x(5-4)+3(x-6)

-15x+12x+3x-18

-3x+3x-18

-18=-12x-6

-12x=-18+6

-12x=-12

MaRussiya [10]

Answer: -1.55

Step-by-step explanation:

Given : Mean : $\mu=100$

Standard deviation : $\sigma=20$

Sample size : $n=60$

Sample mean : $\overline{x}=96$

The test statistic for the population mean is given by :-

$z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

$\Rightarrow\ z=\dfrac{96-100}{\dfrac{20}{\sqrt{60}}}=-1.54919333848\approx-1.55$

Hence, the value of z statistic = -1.55

What’s the x value of PR=9x-31 and QR=43?

True [87]

<h3>Simplifying </h3>

9x + -31 = 43

<h3>Reorder the terms:</h3>

-31 + 9x =43

<h3>Solving</h3>

-31 + 9x =43

<h3>Solving for variable 'x' .</h3><h3>Move all terms containing x to the left, </h3>

Add '31' to each side of the equation .

0 + 31 +9x = 43 + 31

<h3>Combine like terms: </h3>

-31 + 31 =0

0 + 9x = 43 +31

9x = 43 + 31

<h3>Combine like terms:</h3>

43 + 31 =74

9x = 74

<h3>Divide each side by '9'</h3>

x = 8. 222222222

<h3>Simpifying</h3>

x = 8.222222222
