Answer: 0.0432

Step-by-step explanation:

Formula of Margin of Error :-

$E=z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}$

Given : Sample size : n= 400

The proportion of individuals use public transportation.= $\dfrac{65}{330}\approx0.20$

Level of confidence = 0.95

Significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2}=1.96$

Substitute the values in the given formula , we get

$E=(1.96)\sqrt{\dfrac{0.2(1-0.2)}{330}}\\\\\Rightarrow\ E=0.043157779593\approx0.0432$

Hence, the margin of error for the confidence interval for the population proportion with a 95% confidence level. = 0.0432

Rewrite f(x) = 3(x-2)^2+1 from vertex form to standard form

MatroZZZ [7]

Answer:

3x² - 12x + 13

Step-by-step explanation:

given

f(x) = 3(x - 2)² + 1 ← expand (x - 2)²

= 3(x² - 4x + 4) + 1

= 3x² - 12x + 12 + 1

= 3x² - 12x + 13 ← in standard form
