Step-by-step explanation:
A stem-and-leaf plot is a detailed graphical presentation of quantitative data on special kind of table that promotes visualizing the individual numbers in the data with the number at the stem being the first digits of the numbers in the data set while the leaf represent the last digit of each number in the data set
Following the above rule, the data in the given stem-and-leaf plot are;
64, 67, 69, 79, 81, 81, 83, 83, 84, 86, 90, 91, 92, 95
Therefore, the set of data that could have been used to create the stem-and-leaf plot is the data set that has all the numbers in the given stem-and-leaf plot which is the data set;
64, 79, 95, 83, 81, 90, 67, 86, 91, 84, 81, 69, 83, 92.

help finding the circumference
Answer:
approximately equal to 72 centimeters
Step-by-step explanation:
The formula for the circumference of a circle is 2[tex]\pi[/tex]r.
The formula for finding the radius with an arc and an arc length is 180 times l over [tex]\pi[/tex] times the angle.
[tex]\frac{3420}{298.45}[/tex] which is approximately equal to 11.46
11.46 is our radius so the circumference is 2[tex]\pi[/tex](11.46) or about 72

Answer:
Below
Step-by-step explanation:
First, find the difference. You would do
-19 - (-9) = -10
-9 - 1 = -10 and so on...
The difference is -10
Now you need to find what number will make 11 when added to -10.
11 - (-10) = 21
The equation:
y = -10x + 21

Which relationship is true for the triangle based on the Law of Sines?
Answer:
We know the angle given refers to the length of the opposite side.
Given angle = 82 and the opposite side = 34 so part of the relationship is
sin 82 / 34 = sin ( ) / ( )
We are also given one side = 27 and that side is opposite angle at C
so that part of the relationship is sin C / 27
sin 82 / 34 = sin C / 27
A true relationship based on the Law of Sines was found in the given triangle.
In the given triangle
∠A=82°
Length of side in front of ∠A = 34
Length of side in front of ∠C = 27
What is sine law?According to sine law, in a triangle, ABC, if the sides in front of ∠A, ∠B, ∠C are a, b, c respectively then
[tex]\frac{SinA}{a} =\frac{SinB}{b} =\frac{SinC}{c}[/tex]
According to the sine law, the sides in front of angle A and angle C are 34 and 27 respectively.
So, [tex]\frac{Sin82}{34} =\frac{SinC}{27}[/tex]
Hence, a true relationship based on the Law of Sines was found in the given triangle.

The latest online craze is a new game, Khan on Seven. You get 100 points for playing the game. In addition, you get 50 points for each seven-letter word you make with the ten letters you receive. Sal wants to break the record, and he needs 18000 or more points to do so.
Write an inequality to determine the number of seven-letter words, w Sal could make to break the record.
Answer:
Answer: 50x+100\geq18,00050x+100≥18,000
Let w denotes a seven letter word which Sal will need to make to break the record.
Since you get 50 points for each seven-letter and 100 points for playing the game.
Then the total points earned by you by making w seven letters words will be:
50x+10050x+100
Since, Sal wants to break that record, and needs 18,000 points or more to do so.
Then , the required inequality will be :
50x+100\geq18,00050x+100≥18,000

Step-by-step explanation:
in a class of 20 students, how many conversations must be had so that every student talks to every other student in the class?
A) 190
B) 380
C) 760
D) 6840
Answer:
[tex]\text{A) }190[/tex]
Step-by-step explanation:
Similar to the handshake problem, if every student must talk with another person, each student will talk to 19 other students. However, a conversation consists of two people, so we must divide the number of ways we can rearrange the two people ([tex]2![/tex]). Therefore, our answer is [tex]\frac{20\cdot 19}{2!}=\boxed{\text{A) }190}[/tex]

Question: If 2cm represents 75 miles on a scale drawing. How long would a line segment be that represents 50 miles?
Answer:
1.33cm
Step-by-step explanation:
if 2cm is representing 75 miles, that means that .66 (repeating) is representative of 25 miles. This is because .66 (repeating) times 3 is equal to 2, and 25 times 3 is equal to 75. The reason 1.33cm would be equal to 50 miles is because if 25 miles is equal to .66, and 50/25 = 2, then you would have 2x.66 (repeating), to get 1.33.
A rectangle has a side length of 2x and a diagonal of 8x. What is the missing lenght?
Answer:
2x[tex]\sqrt{15}[/tex]
Step-by-step explanation:
we can use the Pythagorean Theorem to find the missing side (a):
a² + (2x)² = (8x)²
a² + 4x² = 64x²
a² = 60x²
a = √60x²
a = [tex]\sqrt{4}[/tex]·[tex]\sqrt{15}[/tex] · [tex]\sqrt{x^2}[/tex]
This can be simplified to be 2x[tex]\sqrt{15}[/tex]
The cereal box shown below is a rectangular prism.
Answer:
Surface area is found:
Surface Area = 1700 cm²
Step-by-step explanation:
(The cereal box is shown in the ATTACHMENT)
The surface area of a rectangular prism can be found by added the areas of all 6 sides of the rectangular prism.
L = length = 20 cm
H = height = 30 cm
W = Width = 5 cm
Side 1:
A(1) = L×H
A(1) = 20×30
A(1) = 600 cm²
Side 2:
As the measurements of the side at the back of side 1 has the same measurement of side 1. then:
A(2) = 600 cm²
Side 3:
A(3) = L×W
A(3) = 20×5
A(3) = 100 cm²
Side 4:
As the measurements of the side at the back of side 4 has the same measurement of side 4. then:
A(4) = 100 cm²
Side 5:
A(5) = H×W
A(5) = 30×5
A(5) = 150 cm²
Side 6:
As the measurements of the side at the back of side 5 has the same measurement of side 5. then:
A(6) = 150 cm²
Surface Area:
Adding areas of all the sides
A(1) + A(2) + A(3) +A(4) + A(5) + A(6) = 600 + 600 + 100 +100 + 150 +150
Surface Area = 1700 cm²

Answer:
DE ≈ 6.97
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos55° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{EF}{DE}[/tex] = [tex]\frac{4}{DE}[/tex] ( multiply both sides by DE )
DE × cos55° = 4 ( divide both sides by cos55° )
DE = [tex]\frac{4}{cos55}[/tex] ≈ 6.97 ( to the nearest hundredth )

Answer:
m∠BFE = 171º
BE = 219º
Step-by-step explanation:
∠BFE is supplementary to ∠EFC
m∠BFE = 180 - 9
m∠BFE = 171º
--------------------------
The angle between two chords is equal to half the sum of the intercepted arcs:
∠BFE = (DC + BE)2
171 = (123 + BE)/2
342 = 123 + BE
219º = BE

Answer:
A. Parallelogram LMNP
B. 33
C. 98°
Step-by-step explanation:
LMNP is a parallelogram.
Adjacent angles of a parallelogram are Supplementary.
[tex] \therefore 82\degree +(3x - 1)\degree =180\degree [/tex]
[tex] \therefore (3x - 1+82)\degree =180\degree [/tex]
[tex] \therefore (3x +81)\degree =180\degree [/tex]
[tex] \therefore 3x +81 =180 [/tex]
[tex] \therefore 3x =180-81 [/tex]
[tex] \therefore 3x =99 [/tex]
[tex] \therefore x =\frac{99}{3} [/tex]
[tex] \therefore x =33 [/tex]
[tex] \implies m\angle N= (3x - 1)\degree=(3*33 - 1)\degree=(99-1)\degree = 98\degree [/tex]
[tex] \because m\angle L =m\angle N[/tex]
(Opposite angles of a parallelogram)
[tex] \therefore m\angle L =98\degree [/tex]

Data are collected about the amount of time, in minutes, each band member spends practicing. How does a single outlier change the lower and upper quartiles of the collected data?
Answer:
A single outlier does not affect the values of the quartiles.
Step-by-step explanation:
It is given that data are collected for each band member that spends time on practicing in minutes.
We know that the interquartile range is defined as [tex]$\text{the difference between the upper quartile,}$[/tex] [tex]Q_3[/tex] and the lower quartile, [tex]Q_1[/tex].
This interquartile range describes the middle i.e. the 50 percent of the values when it is ordered from the lowest to the highest or may be from the highest value to the lowest values.
Therefore, the IQR is considered to be a better measure of the spread then the range since the values are not affected by the outliers.
Therefore, we see that the single outlier does not affect the values of the quartiles, it does not change the lower quartile as well as the upper quartiles.
What is the m∠ACB in the circle shown below?
Question:
What is the m∠ACB in the circle shown below?
Answer:
45
Step-by-step explanation:
So we know it is less than a right angle and it is not a obtuse angle it is less than 90 degrees. 45 is less, 90 is equal(not what we are looking for) , 120, is greater, and 180 is greater which leaves us to our answer 45.
