Hello there, and thank you for posting your question here on brainly.

Let's see if x = 12 by working it out as in the equation.

2 * (12 + 4) - 10 = 36 - 14

I know we should use pemdas, but I'm going to do the 36 - 14, and then work on the left side.

36 - 14 = 22

Now, let us work on the equation.

2 * (12 + 4) - 10 = 22

Let's do the parenthesis first.

12 + 4 ===> 16

Now we have the equation 

2 * 16 - 10 = 22

Multiply 16 by 2.

16 * 2 ===> 32

Almost done, we now have the equation

32 - 10 = 22

Do the subtraction.

32 - 10 ===> 22

22 = 22

Yes, x = 12

Hope this helped!! ☺♥

Answer: (0.132132, 0.274368)

Step-by-step explanation:

Given : A simple random sample of 123 people living in Gastown and finds that 25 have an annual income that is below the poverty line.

i.e. n= 123

\hat{p}=\dfrac{25}{123}\approx0.203252

Critical value for 95% confidence interval : z_{\alpha/2}=1.96

Confidence interval for population :

\hat{p}\pm z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

i.e. 0.203252\pm (1.96)\sqrt{\dfrac{0.203252(1-0.203252)}{123}}

0.203252\pm (1.96)\sqrt{\dfrac{0.203252(1-0.203252)}{123}}\\\\\0.203252\pm0.071118\\\\=(0.20325-0.071118,\ 0.203252+0.071118)\\\\=(0.132132,\ 0.274368)

Hence, the 95% confidence interval for the true proportion of Gastown residents living below the poverty line : (0.132132, 0.274368)

Step-by-step explanation:

small rectangle SA: 6*4 + 6*8 + 6*4 + 6*8 + 4*8 = 176

large rectangle SA: 2*14 + 2*8 + 2*14 + 2*8 + 8*14 + (8*14 - 8*4) = 280

Total SA = 176 + 280 = 456
