Answer:
24.6 < μ < 27.2
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 25.9 - 1.3 = 24.6 pounds.
The upper end of the interval is the sample mean added to M. So it is 25.9 + 1.3 = 27.2 pounds.
So the correct answer is:
24.6 < μ < 27.2
The given statement is true.
Step-by-step explanation:
Given sets are:
D = {x|x is a whole number}
E = {x|x is a perfect square between 1 and 9}
F = {x|x is an even number greater than or equal to 2 and less than 9}
as the sets are given in set builder notation,, we will first write the sets in set notation.
So,
D = {0,1,2,3,4,...}
E = {4,9}
F = {2,4,6,8}
Now,
EUF = {4,9} U {2,4,6,8}
= {2,4,6,8}
Hence,
The given statement is true.

Answer:
Read the excerpt from "Digging"The cold smell of potato mould, the squelch and slapOf soggy peat, the curt cuts of an edgeThrough living roots awaken in my head.But I’ve no spade to follow men like them.Between my finger and my thumbThe squat pen rests.I’ll dig with it.Read the haiku by Bashō. When the winter chrysanthemums go,there’s nothing to write about but radishes.What common concern do these poems share?

Answer:
<em><u>c2=10</u></em>
Step-by-step explanation:
8^2+6^2=c2
64+36=120
c2=square root of 120..which is 10
