Find the area of a regular 15-gon with radius 64 mm
Answers
Answer:
To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.

The Goodsmell perfume company has a new line of perfume and is designing a new bottle for it. Because of
the expense of the glass required to make the bottle, the surface area must be less than 150 cm2. The
company also wants the bottle to contain at least 100mL of perfume. The design under consideration is in the
shape of a cylinder.
Determine the maximum volume possible for a cylindrical bottle that has a total surface area of less than 150
cm2 Determine the volume to the nearest 10mL. Report the dimensions of the bottle and the corresponding
surface are and volume.
This cylindrical perfume bottle needs to be boxed in a prism for sale on store shelves. The Goodsmell perfume
company would like a box with the smallest possible surface area which will contain your design for the
perfume bottle. Report the dimensions of the box and the corresponding area and volume.
The Pretty Perfume company, Goodsmell's competition, has also designed a new perfume bottle. The bottle is
to be a spherical shape with a diameter of 7cm. Determine the volume and surface area of this bottle.
The spherical bottle has a conical shaped lid with a diameter of 5cm and a height of 4.5cm. Given this
information, calculate the volume and surface area of the lid of the spherical shaped bottle.
Determine the dimensions of the smallest possible box which could be used to package Pretty Perfume's new bottle with its spherical bottle and conical-shaped
lid. However, this box is not shaped like a rectangular prism. Pretty Perfume would like to have unique packaging and have chosen to have a box shaped like a
pyramid. Calculate the volume and surface area of this pyramid-shaped box.
The Final Product:
Prepare a written report that includes:
1. A clear and concise explanation of the process that you used to solve the problem.
2. The calculations that you made, presented in an organized fashion.
3. A rationale (reason) for your selection of values.

After answering the question provided, we can predict that the result will be as in the triangle by Pythagorean theorem = [tex]\sqrt{12^2 - 4^2}[/tex] => N = [tex]\sqrt{144 - 16}[/tex] => n = [tex]\sqrt{132}[/tex]
What precisely is a triangle?A triangle is a polygon because it includes four or so additional parts. It features a simple rectangular shape. A rectangle having edges A, B, and C is referred to as a triangle. When the sides are actually not collinear, Euclidean geometry yields a single plane and cube. If a triangle contains three parts and three angles, it is a polygon. The intersections of a triangle's three sides are referred to as its corners. The sum of a triangle's sides is 180 degrees.
by Pythagorean theorem
n = [tex]\sqrt{12^2 - 4^2}[/tex]

A machine, when working properly, produces 5% or less defective items. Whenever the machine produces significantly greater than 5% defective items, it needs repair. A random sample of 300 items taken from the production line contained 27 defective items. Test at the 1% significance level if the percentage of defective items produced by this machine is greater than 5%.
Answers
Answer:
The pvalue of the test is 0.0007 < 0.01, which means that we reject the null hypothesis and accept the alternate hypothesis that the percentage of defective items produced by this machine is greater than 5%.
Step-by-step explanation:
A machine, when working properly, produces 5% or less defective items.
This means that the null hypothesis is:
[tex]H_0: p \leq 0.05[/tex]
Test if the percentage of defective items produced by this machine is greater than 5%.
This means that the alternate hypothesis is:
[tex]H_a: p > 0.05[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
0.05 is tested at the null hypothesis:
This means that [tex]\mu = 0.05, \sigma = \sqrt{0.05*0.95}[/tex]
A random sample of 300 items taken from the production line contained 27 defective items.
This means that [tex]n = 300, X = \frac{27}{300} = 0.09[/tex]
Value of the test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.09 - 0.05}{\frac{\sqrt{0.05*0.95}}{\sqrt{300}}}[/tex]
[tex]z = 3.18[/tex]
Pvalue of the test:
Testing if the mean is greater than a value, which means that the pvalue of the test is 1 subtracted by the pvalue of Z = 3.18, which is the probability of a finding a sample proportion of 0.09 or higher.
Looking at the Z-table, Z = 3.18 has a pvalue of 0.9993
1 - 0.9993 = 0.0007
The pvalue of the test is 0.0007 < 0.01, which means that we reject the null hypothesis and accept the alternate hypothesis that the percentage of defective items produced by this machine is greater than 5%.

You plug the left number into the equation as x and then do the math to find what y should be equal to. This number should be equal to the right number in the parenthesis.
y = 4x-9
y = x-3
Which method and why? Solve, shoving all work
Answers
Answer:
(2,-1)
Step-by-step explanation:
The ys in both questions are isolated on one side of the equation in both. The numerical coefficient of both is 1. Therefore you should equate the the left side of each equation to the other left side. The solution is the easiest one to solve because there is only 1 unknown on both sides.
4x - 9 = x - 3 Subtract x from both sides.
4x-x - 9 = -3 Combine
3x -9 = - 3 Add 9 to both sides
3x - 9+9 = - 3+9
3x = 6 Divide by 3
3x/3 = 6/3
x = 2
===============
Now use the second equation to solve for y
y = x - 3
y = 2 - 3
y = -1
==============
The solution is (2,-1)

Step-by-step explanation:
Given
[tex]S = \{1,2,3,4,5,6\}[/tex] --- sample space
Required
P(not 3)
First, we list out all outcomes that are not 3.
We have:
[tex]Not\ 3 = \{1,2,4,5,6\}[/tex] --- 5 possible outcomes
[tex]S = \{1,2,3,4,5,6\}[/tex] ---- 6 total outcomes
So, P(Not 3) is calculated as:
[tex]P(Not\ 3) = \frac{n(Not\ 3)}{n(S)}[/tex]
[tex]P(Not\ 3) = \frac{5}{6}[/tex]
