Answer:
An outlier is an observation that lies an abnormal distance from other values in a random sample from a population. ... Examination of the data for unusual observations that are far removed from the mass of data. These points are often referred to as outliers. Which explains whether or not 12 is an outlier? Twelve is not an outlier because it is less than the sum of 7 and 6.
Step-by-step explanation:
In the given dataset, twelve is not an outlier because it is less than the sum of 7 and 6.
The outlier of a dataset is the date that are distant from other values of the dataset.
Given that:
[tex]S = \{ 2, 2, 3, 3, 4, 5, 5, 6, 7, 9, 12\}[/tex] --- the dataset
[tex]N = 11[/tex] -- number of observations
[tex]IQR = 4[/tex]
The position of the lower quartile of the above set is:
[tex]Q_1 = \frac{1}{4} \times (N + 1)th[/tex]
[tex]Q_1 = \frac{1}{4} \times (11 + 1)th[/tex]
[tex]Q_1 = \frac{1}{4} \times (12)th[/tex]
[tex]Q_1 = 3rd[/tex]
The 3rd element is 3. So:
[tex]Q_1 = 3[/tex]
Similarly, the position of the upper quartile of the above set is:
[tex]Q_3 = \frac{3}{4} \times (N + 1)th[/tex]
[tex]Q_3 = \frac{3}{4} \times (11 + 1)th[/tex]
[tex]Q_3 = \frac{3}{4} \times (12)th[/tex]
[tex]Q_3 = 9th[/tex]
The 9th element is 7. So:
[tex]Q_3 = 7[/tex]
The lower outlier (L) is
[tex]L = Q_1 - (1.5 \times IQR)[/tex]
[tex]L = 3 - (1.5 \times 4)[/tex]
[tex]L = 3 - 6[/tex]
[tex]L = - 3[/tex]
The upper outlier (U) is:
[tex]U = Q_1 + (1.5 \times IQR)[/tex]
[tex]U = 7 + (1.5 \times 4)[/tex]
[tex]U = 7 + 6[/tex]
[tex]U= 13[/tex]
Values from the lower to the upper outliers are not outliers.
In other words
[tex]-3, -2, -1, 0, 1, 2,......,11,12,13[/tex] are not outliers
12 is not an outlier because it is less than 13
13 is gotten from 7 + 6; as in: [tex]U = 7 + 6[/tex]
Hence, (d) is correct

Abe had 156.43$ in his bank account at the beginning of the month. He made the two withdrawals shown in his check register. How much money does he have left in his bank account? He must have at least 100$ in his account by the end of the month or he will be charged a fee. How much money does he need to deposit to avid being charged a fee?
Answer:
$92.05$7.95Step-by-step explanation:
1. Abe had $156.43 in his account and then withdrew $24.97 and $39.41. The amount left is;
= 156.43 - 24.97 - 39.41
= $92.05
2. He needs to have at least a $100 to avoid a fee so the minimum he needs to deposit is;
= 100 - 92.05
= $7.95
Suppose you work on a tree farm and you need to find the height of each tree. You know that the length of an object with its height. Find the constant of variation
Answer:
The answer is below
Step-by-step explanation:
Suppose you work on a tree farm and you need to find the height of each tree. You know that the length of an object varies directly with its height. a) Find the constant of variation b) find the height of the tree
Solution:
a) Let y represent the length of an object and x represent the height of the object. Given that y ∝ x. Let k be the constant of variation, therefore the relationship between y and x is:
y = kx
y = 2 ft 2 in = 13/6 ft (1 ft = 12 in)
x = 6 ft
Substituting gives:
13/6 = k(6)
k = 13/6 ÷ 6
k = 13/36
b) y = (13/36)x
Given that y = 8ft 4 in = 25/3 ft
Substituting:
y = (13/36)x
25/3 = (13/36)x
x = 25/3 ÷ (13/36)
x= 300/13 ft ≈ 23 ft

cost of 2.5 pounds is $5.6
A. What is the cost of one pound of cheese? Type your answer in the box.
if 2.5 pounds is $5.6
the 1 pound will cost x
cross multiply we have
x=5.6/2.5
x=$2.24
B. Mrs. Peterson bought 4.75 pounds of cheese. How much money did Mrs. Peterson spend on cheese?
we know that 1 pound cost $2.24
therefore 4.75pound, she will spend= 4.75*2.24=$10.64
C. How could you find the cost for 5 pounds of cheese without finding the cost per pound?
we can use the rate for 2.5 pounds at $5.6

4) Use the straightedge to draw RU
Step-by-step explanation:
In order to construct the bisector to an angle
The compass is used to draw an arc that intersects the two rays forming the angle.
From the point of intersection of the arc constructed above and the two rays, two arcs are drawn with the same radius, on the inside of the angle to be bisected, intersecting each other
From the point of intersection of the two arcs drawn wit the same radius, drawn from the intersection of the first arc and the two rays forming the angle to be bisected, a line is drawn with a rule or straightedge to the vertex of the angle to be bisected.

Mathematics.... Use 22/7
Wrong or other answers will be reported
Answer:
A
Step-by-step explanation:
Volume of cylinder= πr²h, where r is the radius
Volume of concrete
= volume of large cylinder -volume of smaller hollow cylinder
Large cylinder:
Diameter= 7m
Since radius= ½(diameter),
Radius= 7 ÷2= 3.5m
Height= 3m
Volume of large cylinder
= π(3.5)²(3)
= 36.75π m³
Small hollow cylinder:
Diameter= 4m
Radius= 4 ÷2= 2m
Height= 3m
Volume of small hollow cylinder
= π(2)²(3)
= 12π m³
Substitute vol. of large and small hollow cylinder with 36.75π and 12π respectively, then substitute 22/7 for π:
Volume of concrete
= 36.75π -12π
= 24.75π
[tex] = 24.75( \frac{22}{7} ) \\ = 77.79 \: m^{3} [/tex]

If you eat in a restaurant and your bill is 45$. what percent tip will you leave?( Assume the service was good) How much will that be? what is the total?
Answer:
$55
Step-by-step explanation:
I would give them a $10 dollar tip if their service was good.
Some people do 15%-20%. or double the tax on the bill. What I would do is 20%, that would be 45*20%=9 or for. so the total would be $54. for 15% you would calculate 15%*45=6.75, so the total would be $51.75.

Step-by-step explanation:
Suppose that you decide to participate in a charity walkathon to raise money for your cause. Some people decide to donate a fixed amount, while others agree to donate a little money for every mile you walk. Before the event starts, you raised $25, and you have been pledged $1.50 for each mile you walk. The function defined by d(m) = 1.5m + 25 can be used to relate the miles you walk, m, and the amount of money donated to you in dollars, d(m).
Evaluate d(3)
Explain what it means in the context of the problem.
While you were walking, you lost track of the number of miles you had walked. At the end of the event, an organizer tells you that you raised $40 through your walk. How many miles did you walk?
Answer:
d(3)=$29.5 is the amount of money raised when you walked 3 miles.
You walked 10 miles fo raise $40
Step-by-step explanation:
The function to model the amount of money raised in the charity walkathon is:
d(m) = 1.5m + 25
Where m is the miles walked.
Evaluate d(3):Substituting m=3:
d(3) = 1.5*3 + 25 = 4.5 + 25 = 29.5
This value is the amount of money raised when you walked 3 miles.
We know you raised $40 but you don't know the number of miles walkedSince we have the function to calculate d(m), and the money raised is known, we have to find the value of m such that this condition is met:
40 = 1.5m + 25
Subtracting 25:
40 - 25 = 1.5m
15 = 1.5m
Dividing by 1.5:
15 / 1.5 = m = 10
It means you walked 10 miles fo raise $40
