Answer:
The upper bound of a 95% confidence interval for the proportion of individuals over the age of 25 in Oregon who do not have a high school diploma is of 0.2568.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of 
.
95% confidence level
So 
, z is the value of Z that has a p-value of 
, so 
.
In a sample of 234 individuals over the age of 25, chosen at random from the state of Oregon, 48 did not have a high school diploma.
This means that 
The upper limit of this interval is:
The upper bound of a 95% confidence interval for the proportion of individuals over the age of 25 in Oregon who do not have a high school diploma is of 0.2568.
Answer:
Step-by-step explanation:
The objective is to state why the value of
converging alternating seies with terms that are non increasing in magnitude
lie between any two consecutive terms of partial sums.
Let alternating series
<span>Sn = partial sum of the series up to n terms</span>
{S2k} = sequence of partial sum of even terms
{S2k+1} = sequence of partial sum of odd terms
As the magnitude of the terms in the
alternating series are non-increasing in magnitude, sequence {S2k} is bounded
above by S1 and sequence {S2k+1} is bounded by S2. So, l lies between S1 and
S2.
In the similar war, if first two terms of the
series are deleted, then l lies in between S3 and S4 and so on.
Hence, the value of converging alternating
series with terms that are non-increasing in magnitude lies between any two
consecutive terms of partial sums. So, the remainder Rn = S – Sn alternating
sign

Step-by-step explanation:
I think you just add the ratios together.
The volume of a pyramid is the one-third of the product of the area of the base and the height of the pyramid.
V = (1/3)Ah
where
A = area of base
h = height of the pyramid
The base of this pyramid is a hexagon.
The area of a regular hexagon is
A = (1/2)pa,
where
p = perimeter of the base
a = apothem
The perimeter of the hexagon is 6 * 6 ft = 36 ft.
The apothem is shown in the figure and is 5.2 ft.
Area of base: (1/2)pa = (1/2)(36 ft)(5.2 ft) = 93.6 ft^2
Volume = (1/3)Ah = (1/3)(93.6 ft^2)(8 ft)
Volume = 249.6 ft^3
Answer: 250 ft^3
