aliya0001 [1]

(2x-8)(7x+5)=0\iff2x-8=0\ \vee\ 7x+5=0\\\\2x-8=0\qquad\text{add 8 to both sides}\\2x=8\qquad\text{divide both sides by 2}\\\boxed{x=4}\\\\7x+5=0\qquad\text{subtract 5 from both sides}\\7x=-5\qquad\text{divide both sides by 7}\\\boxed{x=-\dfrac{5}{7}}

sineoko [7]
<h2>Answer with explanation:</h2>

As per given , we have

p= 0.457

n= 1033

Margin of error for 99​% confidence : E= 4%=0.04

Confidence interval : p\pm E

i.e. 0.457\pm 0.04

=( 0.457- 0.04,\ 0.457+0.04)=(0.417,\ 0.497)

99% confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt. = (0.417, 0.497)

Interpretation : We are 99% sure that the true population proportion of registered voters who are in favor of raising income taxes to pay down the national debt lies in interval (0.417, 0.497).
