We have the following set - {1, 3, 5, 7, 9, 11, 13}.
We have to write a word description of set.
What is Set ?A set is a collection of elements or members, which can be mathematical objects of any kind for example → numbers, symbols, points in space, lines, other geometrical shapes, variables, or even other sets.
According to the question, we have the following set -
{1, 3, 5, 7, 9, 11, 13}
The above set is written in Roster or enumeration notation with the members enlisted between the curly braces. This set consist of 7 elements and each element of this set can be determined using the following rule -
a(n) = 2n - 1
This also represents the set of odd positive integers.

the width of the park?
Explanation:
A square has all four sides the same length. So the length and width are the same.
We can see that (length)*(width) = (1/4)*(1/4) = 1/16 square miles.
If you wanted, you could solve for W in (1/4)*W = 1/16 and you should get W = 1/4.

The volume of a cylinder is 47x cubic units and its height is x units.
Which expression represents the radius of the cylinder, in units?
O 2x
O 4x
O 2pix2
O 4pix2
Answer:
2x
Step-by-step explanation:
The volume of the cylinder is given by the following formula:
pi.r².h
4pix³ = pi x r² x x
r² = 4pix³/pix
r² = 4x²
Rooting both sides
r = 2x
r=2x is the expression represents the radius of the cylinder.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that volume of a cylinder is 4πx³ cubic units and its height is x units.
We need to find the expression which represents the radius of the cylinder.
The volume of the cylinder is given by the following formula:
π.r².h
4πx³ = π x r² x x
Divide both sides by π x
r² = 4πx³/πx
r² = 4x²
Take square root on both sides
r = 2x
Hence, r=2x is the expression represents the radius of the cylinder.

The set of lifespans of an appliance is normally distributed with a mean of 48 months and a standard deviation of eight months. What is the lifespan of an appliance that has a Z score of -3?
Answer:
24 months
Step-by-step explanation:
Given :
Mean = 48
Standard deviation = 8
Zscore = - 3
Using the relation :
Zscore = (x - mean) / standard deviation
Where, x = score
-3 = (x - 48) / 8
-3 * 8 = x - 48
-24 = x - 48
-24 + 48 = x
24 = x
Score = 24
Given the equation 5 + x - 12 = x- 7.
Part A. Solve the equation 5 + x - 12 = x - 7. In your final answer, be sure to state the solution and include all of your work.
Part B. Use the values x -4, 0, 5 to prove your solution to the equation 5 + x - 12 F x - 7. In your final answer, include all
of your calculations.
Answer:
Step-by-step explanation:
5 + x - 12 = x- 7 (Add the 5 and -12 to simplify)
x - 7 = x - 7 (notice its the same on both sides of equal sign. Add 7 to both sides)
x = x
solution is all real numbers
Part B
5 - 4 - 12 = -4 - 7
-11 = -11
5 + 0 - 12 = 0 - 7
-7 = -7
5 + 5 - 12 = 5 - 7

Find the surface area of the prism.
Answer:
256 ft^2
Step-by-step explanation:
1. Find the base's area. 6 ft x 13 ft = 78 ft ^2
2. Find the area of one of the sides (if you know what I mean). 13 ft x 5 ft = 65 ft ^2
3. Find the area of the front (it's the triangle). 6 ft x 4 ft = 24 ft ^2 (no need to times by 1/2)
4. Before we add them all together, there are two of the sames sides that have an area of 65 ft (^2), so you add them twice. Same goes to the triangles (because there is one triangle in the front and one on the back).
5. Add.
65 ft ^2 + 65 ft ^2 + 78 ft ^2 + 24 ft ^2 + 24 ft ^2 = 256 ft^2
Answer:
B
Step-by-step explanation:
Base area = (length x height)/2 = (6 x 4)/2 = 12 ft^2
Base perimeter = (side 1 + side 2 + side 3) = 6 + 5 + 5 = 16 ft
LA = base perimeter x 13 = 16 x 13 = 208 ft^2
SA = (base area x 2) + LA = 24 + 208 = 232 ft^2

In the circle below, the measure of arc QT is 50 and the measure of angle P is 55,
What is the measure of arc RS?
Answer:
C. 160degrees
Step-by-step explanation:
Find the diagram attached
From the diagram;
<P = 1/2(arcRS - arcQT)
Given the following
arcQT = 50degrees
<P = 55 degrees
Required
arcRS
55 = 1/2(arcRS - 50)
2*55 = arcRS - 50
110 = arcRS - 50
arcRS = 110 + 50
arcRS = 160degrees
Hence the measure of arcRS is 160degrees

The Rocky Mountain News (January 24, 1994) indicated that the 20-year mean snowfall in the Denver/Boulder region is 28.76 inches with standard deviation of 7.5 inches. However, for the winter of 1993-1994, the average snowfall for a sample of 32 different locations was 33 inches.
Required:
Does this indicate thatthe snowfall for the 1993-1994 winters has higher than the previous20-year average?
Answer:
The p-value of the test is 0.0007 < 0.05, indicating that the the snowfall for the 1993-1994 winters was higher than the previous 20-year average.
Step-by-step explanation:
20-year mean snowfall in the Denver/Boulder region is 28.76 inches. Test if the snowfall for the 1993-1994 winters has higher than the previous 20-year average.
At the null hypothesis, we test if the average was the same, that is, of 28.76 inches. So
[tex]H_0: \mu = 28.76[/tex]
At the alternate hypothesis, we test if the average incresaed, that is, it was higher than 28.76 inches. So
[tex]H_1: \mu > 28.76[/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.
28.76 is tested at the null hypothesis:
This means that [tex]\mu = 28.76[/tex]
Standard deviation of 7.5 inches. However, for the winter of 1993-1994, the average snowfall for a sample of 32 different locations was 33 inches.
This means that [tex]\sigma = 7.5, X = 33, n = 32[/tex].
Value of the test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{33 - 28.76}{\frac{7.5}{\sqrt{32}}}[/tex]
[tex]z = 3.2[/tex]
P-value of the test and decision:
The p-value of the test is the probability of finding a sample mean above 33, which is 1 subtracted by the p-value of z = 3.2. In this question, we consider the standard level [tex]\alpha = 0.05[/tex].
Looking at the z-table, z = 3.2 has a p-value of 0.9993.
1 - 0.9993 = 0.0007
The p-value of the test is 0.0007 < 0.05, indicating that the the snowfall for the 1993-1994 winters was higher than the previous 20-year average.
