There are no outliers in this distribution.
The shape of the boxplot is fairly symmetric.
The range of the distribution is around 60 cm.
The center of the distribution is around 180 cm.
The statement "The range of the distribution is around 60 cm" is true.
The range is the spread of your data from the lowest to the highest value in the distribution.
In the given graph
Range=200-140
=60
So it is true.
The center of the distribution is around 180 cm is also true.
Hence the statements The range of the distribution is around 60 cm and

I don´t quite understand this Question 5% of 40
Answers
Answer:
5% of 40 = 20
Step-by-step explanation:
To find 5% of 40, you can turn the 5% to 0.5, and the "of" means multiplication.
So, in turn you would have:

The unknown angles are as follows:
m∠EFH = 80°m∠EFG = 160°The value of ST in the line segment is 22 units.
How to find angles and mid points?An angle bisector is a bisector that bisect an angles into two equal parts.
Therefore, EF is the angle bisector of ∠EFG.
The bisector divides the ∠EFG equally into ∠EFH and ∠HFG.
Hence,
∠EFH = ∠HFG
m∠HFG = 80°
m∠EFH = 80°
m∠EFG = 80 + 80
m∠EFG = 160°
12.
Let's find ST in the line segment.
PT = 40
QS = 12
PQ = QR = RS = x
QR + RS = QS
2x = 12
x = 12 / 2
x = 6
Therefore,
PQ = QR = RS = 6 units
PS = PQ + QR + RS
PS = 6 + 6 + 6
PS = 18 units
Hence,
ST = PT - PS
ST = 40 - 18
ST = 22 units

Evelyn needs to order some new supplies for the restaurant where she works. The restaurant needs at least 769 glasses. There are currently 205 glasses. If each set on sale contains 12 glasses, write and solve an inequality which can be used to determine xx, the number of sets of glasses Evelyn could buy for the restaurant to have enough glasses.
Answers
Answer: 769 bottles ≤ 12x + 205, or 564 bottles ≤ 12x
Step-by-step explanation:
➜ They need at least 769 bottles, so our inequality will use either ≤ or ≥ depending on how we set it up.
➜ They currently have 205 bottles, so we will use addition to show there are some glasses currently owned
➜ If each set contains 12 glasses, we will multiply x, the number of sets bought, by 12
With these details, we will write an inequality.
769 bottles ≤ 12x + 205

20 = 4 (y + 8) - 8y solve for y and simplify your answer as much as possible
Answers
Answer:
y = 3
Step-by-step explanation:
20 = 4 (y + 8) - 8y
20 = 4y + 32 - 8y
20 - 32 = 4y - 8y
-12 = -4y
-4y = -12
-4y/-4 = -12/-4
y = 3
To check
20 = 4 (y + 8) - 8y
20 = 4 (3 + 8) - 8(3)
20 = 12 + 32 - 24
20 = 44 - 24
20 = 20
Correct~
Answer: y = 3
Step-by-step explanation:
1. Distribute the 4 to the terms in the parenthesis.
20 = 4y + 32 - 8y
2. Combine like terms (those containing y).
20 = -4y + 32
3. Isolate terms with y by subtracting 32 from both sides.
-12 = -4y
4. Divide both sides by -4.
3 = y

If <1 and <2 are
supplementary angles with
m <1 = 10x +5 and m <2= 6x-1, what are the measure-
ments of both angles?
Answers
Step-by-step explanation:
The sum of measure of supplementary angles = 180°
The measure of angle 1 is given as 10x + 5 and the measure of angle 2 is given as 6x - 1
10x + 5 + 6x - 1 = 180 add like terms
16x + 4 = 180 subtract 4 from both sides
16x = 176 divide both sides by 16
x = 11
To find the measure of each angle, relace x with 11
angle 1,
10*11 + 5 = 115
angle 2,
6*11 - 1 = 65

April is arranging place cards for a wedding reception on a table. The bride's family has 154 cards and the groom's family has 140 cards. She wants the arrangements for the two families to have the same number of cards in each row. What is the greatest number of cards that she can place in a row?
Answers
The greatest number of cards that April can place in a row , so that the two families have same number of cards in each row is 14.
In the question ;
it is given that
number of card that Bride's family has = 154
number of cards that Groom's family has = 140 cards.
So , to find the greatest number of cards that April can place in a row we need to find the GCF(154,140) ,
to find the GCF (154,140)
prime factorization of 154 = 2*7*11
prime factorization of 140 = 2*2*5*7
common factors = 2*7
Hence the GCF(154,140) = 14
Therefore , the greatest number of cards that April can place in a row , so that the two families have same number of cards in each row is 14.
