Area of a rectangle is (6x25x + 2) sq. units.
nadya68 [22]
<h2><u><em>Answer:  meters. </em></u></h2><h2><u><em> </em></u></h2><h2><u><em>Step-by-step explanation:  Let L be the length of the rectangle.  We have been given that the rectangle has an area of square meters and a width of meters.  Since we know that area of a rectangle is the product of its length and width.  To find the length of our given rectangle we will divide the area of the rectangle by the width of our rectangle.  Let us factor out our numerator by splitting the middle term.  Upon canceling out x-7 from numerator and denominator we will get,  Therefore, the length of our rectangle will be metered.</em></u></h2>

A major metropolitan newspaper selected a simple random sample of 1,600 readers from their list of 100,000 subscribers.
Tpy6a [65]

Answer: (0.36845,\ 0.43155)

Step-by-step explanation:

Let p be the population proportion of  readers who would like more coverage of local news.

As per given , we have

sample size :=1600

sample proportion : \hat{p}=40\%=0.40

The confidence interval for population proportion is given by :-

\hat{p}\pm z^* \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

From z-table ,

For 99% confidence interval the z-value is 2.576.

Substitute all the values in the above formula , we get

The 99% confidence interval for the proportion of readers who would like more coverage of local news as

0.40\pm(2.576) \sqrt{\dfrac{0.40(1-0.40)}{1600}}

0.40\pm(2.576) \sqrt{\dfrac{0.24}{1600}}

0.40\pm(2.576) \sqrt{0.00015}

0.40\pm(2.576) (0.0122474487139)

0.40\pm0.03155

(0.40-0.03155,\ 0.40+0.03155)=(0.36845,\ 0.43155)

Hence, the 99% confidence interval for the proportion of readers who would like more coverage of local news is (0.36845,\ 0.43155) .
