Answer:

Paris

Step-by-step explanation:

In London we get

£1 = €1.14

In Paris we get

£0.86=€1

dividing both sides by 0.86 gives:

£1 = €1/0.86=€1.16 in Paris

so in Paris you get more € for the same £1

"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

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

⇒ $1.98^2-4\times 0.05^2n=0$

⇒ $n=\frac{1.96^2}{4\times 0.05^2}$

⇒ $n=384.16=384$

Simplify the expression by combining like terms :

Yuki888 [10]

Here is your answer:

2b + 7b^2 - 2 + 3b - 1 + b
Combine 2b and 3b
2b+3b=5b
Then do the exponent rule:
7×7=49b
Which equals:

(5b) b^2 + ( 2 ) b + (4b)
