Answer:
d = 46.15
A = 1672.76
Hope this helps!
Answer:
Diameter = 46.18 inches
Area = 1,674.09 square inches
Step-by-step explanation:
Circumference = pi x diameter
145 = 3.14d
divide both sides by 3.14
d = 46.1783 inches
------------------------
radius = 1/2 x diameter
r = 23.09
Area = (pi)(r)^2
A = (3.14)(23.09)(23.09)
A = 1,674.09 square inches
On their birthdays, employees at a large company are permitted to take a 60-minute lunch break instead of the usual 30 minutes. Data were obtained from 10 randomly selected company employees on the amount of time that each actually took for lunch on his or her birthday. The company wishes to investigate whether these data provide convincing evidence that the mean time is greater than 60 minutes. Of the following, which information would NOT be expected to be a part of the process of correctly conducting a hypothesis test to investigate the question, at the 0.05 level of significance?
A. Being willing to assume that the distribution of actual birthday lunch times for all employees at the company is approximately normal
B. Knowing that there are no outliers in the data as indicated by the normal probability plot and boxplot
C. Using a t-statistic to carry out the test
D. Using 9 for the number of degrees of freedom
E. Given that the p-value is greater than 0.05, rejecting the null hypothesis and concluding that the mean time was not greater than 60 minutes.
Answers
Answer:
The answer is "Option E"
Step-by-step explanation:
The null hypothesis was rejected so because the p-value was greater than 0.05, indicating that perhaps the meantime was not greater than 60 minutes.
Find the volume of a right circular cylinder with a diameter of 14 inches and a height of 10 inches, answer in terms of pi?
Answers
Answer:
490π
Step-by-step explanation:
Given data
Diameter= 14 inches
Radius= 7 inches
Height = 10 inches
The expression for the volume of a cylinder is
V= πr^h
V= π*7^2*10
V= 490π
Hence the volume is 490π

The perimeter of a rectangle is 84 feet long. The
length is six more than two times its width. What are
the dimensions of the rectangle? (Hint: P = 2L + 2W)
Answers
Therefore , the solution of the given problem of perimeter comes out to be length = 16.8 and width = 50.4
Establish a perimeter.The perimeter, or total length, of a shape is referred to as its perimeter in geometry. A shape's perimeter is calculated by summing the lengths of all of its sides and edges. By adding together the lengths of all a shape's sides, one may determine its perimeter. The circumference of a field, for instance, will be 78 yards for a rectangle with dimensions of 24 yards long by 15 yards wide.
Here,
Given :
Perimeter of rectangle = 84 feet
Thus,
Length is 6 times more than its 2 time width
=> 6L = 2W
=> W = 3L
In the perimeter formula:
=> 3L + 2L =84
=> 5L = 84
=>L = 84/5
=>16.8
and
W = 3L
=> W = 3*16.8
=> W = 50.4
Therefore , the solution of the given problem of perimeter comes out to be length = 16.8 and width = 50.4

How would the information collected using transect or quadrat sampling differ from the information collected if you had just divided the habitat into quarters and sampled only one of the quarters
Answers
I feel that dividing based off actual zoning laws and regulations would provide the best source of data. I feel as such because if you simply devise your own areas, that may make your data incorrect depending on what area a person actually associates with. If you're creating your own area, information could get misconstrued leading to inaccurate conclusions.
Sampling
Sampling means selecting the group that you will actually collect data from in your research.
zoning
Zoning is a method of urban planning in which a municipality or other tier of government divides land into areas called zones, each of which has a set of regulations for new development that differs from other zones.

Step-by-step explanation:
The slope would be 1. Using the equation y^2 - y^1 / x^2 -x^1, you would substitute the plots into the equation. -5 + 13 / 1 + 7 = 8/8 or 1. The 13 and 7 would be added because subtracting a negative is the same as adding a positive.
What is the radius of circle M?
Answers
Answer:
The radius is just under 4 cm.
Step-by-step explanation:
The central angle for the entire circle is 360 degrees.
The fraction (89/360)(total circle area) = 12.36m^2.
Solving for the total circle area, we get (360/89)(12.36m^2) = 50 cm^2.
Area of a circle (in general) is A = πr²
Here we know A and π and must find r² and then r:
A
A = πr² becomes r² = ----------
π
Here, r² = 50 cm^2 / 3.14 = 15.92 cm^2
and r = square root of r² = 3.99, or approximately 4 cm

The value of the measure of ∠O in the given triangle will be 65°
What is triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
In ΔNOP;
PN ≅ OP
So, ∠O = ∠N
And, Measure of ∠P = 50°
Now,
In the ΔNOP;
The sum of all the three angles are 180°.
The value of the measure of ∠O = x
We get;
∠O + ∠N + ∠P = 180°
Substitute ∠P = 50° and ∠O = ∠N = x we get;
x + x + 50 = 180
2x + 50 = 180
2x = 180 - 50
2x = 130
x = 65
Thus, The value of the measure of ∠O will be 65°.

What is the formula to find the side?
Answers
The formula to find the side of a geometric shape depends on the shape itself. Few details like area or perimeter of a shape or surface area or volume of a solid with few other parameters should be known.
Few examples :
For a square, the formula to find the side (s) is:
s = √(A)
where A is the area of the square.
For a rectangle, the formula to find the length (l) and width (w) are:
l = A/w and w = A/l
where A is the area of the rectangle.
For a triangle, the formula to find the base (b) and height (h) are:
A = (b*h)/2
where A is the area of the triangle.
For a cube, the formula to find the side (s) is:
V = s^3
where V is the volume of the cube.
Keep in mind that these are a few examples of formulas that can be used to find the side of a geometric shape. Depending on the specific problem, different formulas may be required.

Yolanda spends 8 2/3 hours per month playing soccer. approximately how many hours does she play soccer in a year?
Answers
Answer:
[tex]8 \frac{2}{3} \times 12 = 104[/tex]
Therefore, she spends 104 hours a year playing soccer.
Answer:
104 hours
Step-by-step explanation:
1 year = 12 months
Since 1 year equals 12 months, we multiply the time she spends in 1 month by 12 to calculate the time she spends in 1 year.
8 2/3 hours × 12
= (8 + 2/3) hours × 12

A lottery game contains 24 balls numbered 1 through 24. What is the probability of choosing a ball numbered 25
Answers
Selecting ball number 25 has no chance of happening.
Explain about the probability?Probability is only the likelihood that something will occur. When we don't know how something will turn out, we might discuss the likelihood of various outcomes or the potential of one. Statistics is the scientific study of events that conform to a probability distribution.
It is predicated on the likelihood that something will take place. The rationale for probability serves as the theoretical probability's essential tenet. A coin has a 12% chance of landing on its head, for instance, when it is flipped.
Probability is a statistic that is used to indicate the likelihood or potential for an event to occur. Both fractions from 0 to 1 and percentages from 0% to 100% can be used to indicate probabilities.
