Solve for x. 3x ^2 -4 = 8

LenKa [72]

Answer:

x = ±2

Step-by-step explanation:

3x ^2 -4 = 8

Add 4 to each side

3x ^2 -4+4 = 8+4

3x^2 =12

Divide each side by 3

3x^2 =12

3x^2/3 = 12/3

x^2 = 4

Take the square root of each side

sqrt(x^2) = ±sqrt(4)

x = ±2

Suppose a polling agency reported that 44.4% of registered voters were in favor of raising income taxes to pay down the nationa

g100num [7]

Answer:

<em>95% of confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt.</em>

<em>(0.414 ,0.474)</em>

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

<em>Given sample proportion </em>

<em> p⁻ = 44.4 % = 0.444</em>

<em>Random sample size 'n' = 1049</em>

<em>Given margin of error for 95% confidence level = 3 % = 0.03</em>

<u><em>Step(ii):-</em></u>

<em>95% of confidence interval for the proportion is determined by</em>

$(p^{-} - Z_{\alpha }\sqrt{\frac{p^{-} (1-p^{-} }{n} } , p^{-} + Z_{\alpha }\sqrt{\frac{p^{-} (1-p^{-} }{n} })$ <em></em>

we know that

<em>Margin of error for 95% confidence level is determined by</em>

$M.E = Z_{\alpha }\sqrt{\frac{p^{-} (1-p^{-}) }{n} }$

<u><em>Step(iii):-</em></u>

Now

<em> 95% of confidence interval for the proportion is determined by</em>

$(p^{-} - M.E, p^{-} + M.E)$ <em></em>

<em>Given Margin of error </em>

<em> M.E = 0.03</em>

<em>Now 95% of confidence interval for the proportion</em>

$(0.444 - 0.03, 0.444+ 0.03)$ <em></em>

<em>(0.414 ,0.474)</em>

<u><em>Conclusion:-</em></u>

<em>95% of confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt.</em>

<em>(0.414 ,0.474)</em>
