Answer:

d = 115.4 mi

Step-by-step explanation:

Since it gives us the distance in between the locations, we simply label the distances:

From the Garbage to the Hotel is 58.3 miles.

From the Hotel to the Hardware Store is 57.1 miles.

We are trying to find the distance from the Garbage to the Hardware Store, we simply add the distances between:

58.3 mi + 57.1 mi = 115.4 mi

ladessa [460]

Toyland is having a sale all items are 20% off

so all items are sold at 1-20% = 80% of their original prices

for an item that usually costs $95,

the sale price = $95 * 80% = $95 * 0.8

= $76

n a study of cell phone use and brain hemispheric dominance, an Internet survey was e-mailed to 2472 subjects randomly selecte

Leona [35]

Answer:

0.3876<p<0.4389

Step-by-step explanation:

-Given $n=2472, \ x=1022 , \ CI=0.99$

-We calculate the proportion of surveys returned:

$\hat p=\frac{1022}{2472}\\\\=0.4134$

For a 99% confidence interval:

$z_{\alpha/2}=2.576$

#The margin of error is calculated as;

$ME=z_{0.005}\times \sqrt{\frac{\hat p(1-\hat p)}{n}}\\\\=2.576\times \sqrt{\frac{0.4134(1-0.4134)}{2472}}\\\\=0.0255$

The confidence interval are then:

$CI=\hat p\pm ME\\\\=0.4134\pm 0.0255\\\\=[0.3876,0.4389]$

Hence, the confidence interval is 0.3876<p<0.4389
