Step-by-step explanation:

You can first multiply the width by two. Then you subtract that from you perimeter to figure out your length. Whatever number you get divide it by two and there's your length.

Example:

Perimeter =30 Width=5

5 times 2= 10

30-10=20

20/2=10

So your length equals 10.

I hope this helps!

mezya [45]

Answer:

The confidence interval is (24116.3878,24883.6122).

Step-by-step explanation:

We are given the following information in the question:

Population mean, \mu = $23,500

Sample mean,\bar{x} = $24,500

Sample standard deviation,s = $2,800

Sample size, n =  146

Confidence interval:

\bar{x} \pm t_{critical}\frac{s}{\sqrt{n}}  

Putting the values, we get,

t_{critical}\text{ at}~\alpha_{0.05} = \pm 1.655436

24500 \pm 1.65543(\frac{2800}{\sqrt{146}} ) = 24500 \pm 383.6122 = (24116.3878,24883.6122)

The confidence interval is (24116.3878,24883.6122).

A) 2 units
B) yes

For A) |5-3|=|2|=2 is the distance from his house to school.

For B)
The distance from his house to school is 2 units; the distance from school to the grocery store is |3--9|=|12|=12.  The total distance is 2+12 = 14.

The distance from his house to school is 2 units; the distance from school to the community center is |-4-6|=|-10|=10.  The total distance is 2+10 = 12.

The distance from the house to the school to the grocery store is greater.
