r(b) = 12b

c(b) = 4 + 3.3b

I think profit is revenue minus the cost, so p(b) = r(b) - c(b)

= 12b - (4 + 3.3b)

12b - 4 - 3.3b //Combine like terms

8.7b - 4

Answer: D

//Hope it helps and it's right.

Answer: B. 0.036

Step-by-step explanation:

Formula for standard error :

$SE=\sqrt{\dfrac{p(1-p)}{n}}$

, where p = Population proportion and n= sample size.

Let p be the population proportion of the people who favor new taxes.

As per given , we have

n= 170

$p=\dfrac{55}{170}\approx0.324$

Substitute these values in the formula, we get

$SE=\sqrt{\dfrac{0.324(1-0.324)}{170}}\\\\=\sqrt{0.00129}\\\\=0.0359165699921\approx0.036$

Hence, the standard error of the estimate is 0.036.

∴ The correct answer is OPTION B. 0.036
