Factor using a GCF:<br> 16xy2+28xy+8y

Lorico [155]

Answer:

4y( 4xy + 7x +2)

Step-by-step explanation:

16xy^2+28xy+8y

16xy^2 =2*2*2*2*x*y*y

28xy = 2*2*7 *x*y

8y = 2*2*2*y

The common factors are 2*2*y = 4y

2*2*2*2*x*y*y + 2*2*7 *x*y+2*2*2*y

2*2*y( 2*2*x*y + 7 *x+2)

4y( 4xy + 7x +2)

Nastasia [14]

Answer:

Sample size is $n=423$

Step-by-step explanation:

Given that,

Margin of error $=4$ %

Confidence level $=90$ %

Suppose, sample proportion $=0.5$

i.e. $\hat{P}=0.5$

We know that,

Margin of error $=2^*\sqrt{\frac{\hat{p}(1-\hat{p})}{n} }$

∴ $1.64\sqrt{\frac{0.5(0.5)}{n} } \leq 4\%$

$\Rightarrow 1.64\sqrt{\frac{0.25}{n} } \leq 0.04$

$\Rightarrow \frac{0.5}{\sqrt{n} } \leq \frac{0.04}{1.64}$

$\Rightarrow \frac{0.5}{\sqrt{n} } \leq 0.0243$

$\Rightarrow \sqrt{n}\geq \frac{0.5}{0.0243}$

$\Rightarrow \sqrt{n}\geq 20.57$

squaring on both side,

∴ $n=423.1249$

Hence, the sample size is,

$n=423$

Hence, the correct option is $(b).$
