"A state legislator wishes to survey residents of her district to see what proportion of the registered voters are aware of her

aliya0001 [1]

Answer:

The correct answer to the following question will be "384".

Step-by-step explanation:

We are having,

$P(-0.05$

On solving, we get

⇒ $P(\frac{-0.05}{\sqrt{\frac{pq}{n}}}$

⇒ $\frac{0.05}{\sqrt{\frac{p(1-p)}{n}}} =1.96$

On applying cross-multiplication, we get

⇒ $0.05^2=1.96^2\times \frac{P(1-p)}{n}$

⇒ $0.05^2n=1.96^2-1.96^2p^2$

⇒ $1.96^2p^2-1.96^2p+0.05^2n=0$ ...(equation 1)

When "p" seems to be the population proportion, (equation 1) approach, which is special

∴ $b^2-4ac=0$

On putting the values in the above expression, we get

⇒ $(1.96)^4-4\times 0.05^2\times 1.96^2n=0$

⇒ $1.98^2-4\times 0.05^2n=0$

⇒ $n=\frac{1.96^2}{4\times 0.05^2}$

⇒ $n=384.16=384$

How do you solve this equation 2/3b=-12

Airida [17]

2/3b = 12

First you have to get rid of 2/3, so you multiply both sides by its reciprical:
(3/2) 2/3b = 12 (3/2) -->b = 36/2 --> b = 18
