Solve this please, and quick

Error: They subtracted 9x from both sides when they should have subtracted 12. You can’t subtract unlike terms
Correct: x=-5/16
Subtract 12 from both sides to get -5 on the left and add 7x and 9x to get 16x. Divide both sides by 16 to isolate x.

0.5 bigger than 9/18

aleksley [76]

No, 0.5 = 9/18.

9/18 can be simplified to 1/2, which is 0.5

Hope this helped! :)

Answer: The standard error for sample is 0.0686 .

Step-by-step explanation:

We know that the formula to find the standard error is given by :-

$S.E.=\dfrac{s}{\sqrt{n}}$

, where s = standard deviation

n= Sample size

As per given , we have

s= $0.4 and n= 34

Then , the standard error for sample is given by :-

$S.E.=\dfrac{0.4}{\sqrt{34}}=\dfrac{0.4}{5.83095189485}\\\\=0.0685994340569\approx0.0686$

Hence , the standard error for sample is 0.0686 .
