You're a quality control manager in a fruit juice company. You want to choose
a sample size for a quality check on the cans used to package the juice. From
a batch of 30,000 cans, you want a sample size that will allow you to closely
approximate the population parameters for the entire batch. Which sample
size will most likely produce the least variability among different samples?
Answer:
246.
Step-by-step explanation:
a) The 95% confidence level two-tail confidence interval for the mean value of the key index of this batch is between 98.22 and 99.78
b) The minimum sample size to achieve this is 246.
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(square root of the variance) and n is the size of the sample. So in this question,
The lower end of the interval is the sample mean subtracted by M. So it is 99 - 0.78 = 98.22
The upper end of the interval is the sample mean added to M. So it is 99 + 0.78 = 99.78.
a) The 95% confidence level two-tail confidence interval for the mean value of the key index of this batch is between 98.22 and 99.78
(b) (5 points) If we want the sampling error to be no greater than 0.5, what is the minimum sample size to achieve this based on the same confidence level with part (a)
We need a sample size of n
n is found when
Then
Rounding up
The minimum sample size to achieve this is 246.

Compare and contrast pyramids and cones.
Be sure to use mathematical terms to describe parts of the solids.
a. In what ways are they alike?
b. In what ways are they different?
Choose either pyramids or cones, and explain how the formula for their volume can be described using other solids.
Answer:
Similarities: both have a base which extends into a single vertex.
Differences: a cone only has 1 edge and a pyramid has a minimum of 6 (for a triangular pyramid).
the base of a pyramid is a polygon - the base of a cone is a curve
(a mathematical cone has no edges at all it is a continuous sheet - or two sheets if you consider the vertex as dividing the surface into two sheets).
Step-by-step explanation:
brainliest?
The key difference between Pyramids and cones are:
A pyramid is basically a code that has a base in the form of a polygon.
Pyramids and cones are alike in the following ways:
Because a cone can be made from a right angle triangle, their formulas are also alike in some ways. Notice that both formulas are related to the height of the object.
The formula for the area of a right angle triangle is:
A = hb/2
The area of a cone is given as:
A = [tex]\pi[/tex] r (r + [tex]\sqrt{(h²+r²)}[/tex]

The elevator at the state capital has a maximum weight capacity of 2000 pounds. If there are 3
people already on the elevator with a combined weight of 428 pounds, write an inequality to express
the possible weights that may be added to the elevator,
Part A: Define your variable
Part B: Write the inequality
Part C: Describe what your inequality looks like on a number line. Be sure to include whether the
circle is open or closed and the direction the line is shaded.
Answer:
Step-by-step explanation:
Maximum capacity of the elevator = 2000 pounds
Combined weight of the elevator = 428 pounds
A). Let the possible weights that can be added to the elevator = w pounds
B). Therefore, inequality representing this situation will be,
428 + w < 2000
C). By solving the given inequality,
(428 + w) - 428 < 2000 - 428
w < 1572 pounds
Now we draw this inequality on a number line.

Given:
Endpoints of a line segment EF are E(-3,8) and F(7,-7).
Point P divides the segment EF such that EP:PF = 2:3.
To find:
The coordinates of the point P.
Solution:
Section formula: If a point divides a line segment in m:n, then the coordinates of the points are:
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
It is given that EP:PF = 2:3. It means the point P divides the segment EF in 2:3.
Using section formula, we get
[tex]P=\left(\dfrac{2(7)+3(-3)}{2+3},\dfrac{2(-7)+3(8)}{2+3}\right)[/tex]
[tex]P=\left(\dfrac{14-9}{5},\dfrac{-14+24}{5}\right)[/tex]
[tex]P=\left(\dfrac{5}{5},\dfrac{10}{5}\right)[/tex]
[tex]P=\left(1,2\right)[/tex]
Therefore, the coordinates of the point P are (1,2).
