what is the answer for
5x - 2 = 3x + 4
Answer: X = 3
Step-by-step explanation:
5x - 2 = 3x + 4
5x = 3x + 6 (+2 to both sides)
2x = 6
x = 3
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]

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

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.

#3. 6.4, 7.9, 9.5, 8.3, 8.1, 9.0, 6.7, 8.6, 9.1, 8.4, 8.1, 6.9, 8.3, 9.2
#4. 63, 79, 95, 83, 81, 90, 67, 86, 91, 84, 81, 69, 83, 92
Answer:
#2 64, 79, 95, 83, 81, 90, 67, 86, 91, 84, 81, 69, 83, 92
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.

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.
In ΔNOP, the measure of ∠P=90°, NO = 49 feet, and OP = 19 feet. Find the measure of ∠N to the nearest degree.
Answer:
N=22.815≈23
Step-by-step explanation:
SIN N=19/49
N=\sin^{-1}(\frac{19}{49})
N=sin
N=22.815≈23

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]

Find the sum of the 1st 100 terms: 100+98+96+......
50
100
-98
1000
Answer:
100
Step-by-step explanation:
Given :
Terms ( n ) = 100
First term ( a ) = 100
Series = > 100 + 98 + 96 .......
Common difference ( d ) = 98 - 100 = > - 2
We know sum formula:
S_n = ( n / 2 ) ( 2 a + ( n - 1 ) d )
= > S_100 = ( 100 / 2 ) ( 200 + ( 100 - 1 ) - 2 )
= > S_100 = 50 ( 200 - 198 )
= > S_100 = 50 ( 2 )
= > S_100 = 100
Therefore, sum of first 100 terms is 100.
Consider this equation. Cos(0) = 8/9 if 0 is an angle in quadrant IV, what is the value of tan(0)? I
Answer:
[tex]\displaystyle \tan(\theta)=-\frac{\sqrt{17}}{8}[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \cos(\theta)=\frac{8}{9}[/tex]
Where θ is in QIV.
And we want to find the value of tan(θ).
Recall that cosine is the ratio of the adjacent side over the hypotenuse.
Therefore, the opposite side is:
[tex]o=\sqrt{9^2-8^2}=\sqrt{17}[/tex]
Next, in QIV, only cosine is positive: sine and tangent are both negative.
Tangent is the ratio of the opposite side to the adjacent. So:
[tex]\displaystyle \tan(\theta)=\frac{\text{opposite}}{\text{adjacent}}[/tex]
Substitute. Tangent is negative in QIV. Hence:
[tex]\displaystyle \tan(\theta)=-\frac{\sqrt{17}}{8}[/tex]
PLS HELP WILL MARK BRAINLIEST The average of eight consecutive odd integers is 48. What is the range of these eight numbers?
Answer:
Step-by-step explanation:
2x - 7 + 2x - 5 + 2x - 3 + 2x - 1 + 2x + 3 + 2x + 5 + 2x + 7 Combine like terms
16x / 8 = 48
2x = 48
x = 24
The range is defined as the largest number - the smallest number
The range is between 2x - 7 and 2x + 7
x = 24
The smallest number is 48 - 7 = 41
The largest number is 48 + 7 = 55
The range = 55 - 41 = 14
Why was the 2 in front of the x needed? It was to make sure that I could create an odd number.
Why did I subtract an odd number? That was to make sure that I could create odd numbers.
Why did I start with 2x - 7 and end up 8 terms later at 2x + 7?
So the numbers would cancel and I'd only be left with x's.

So far Monica has read 5/6 of book she has read the same number of pages each day for 5 days. What fraction of the book does Monica read each other ?
Answer:
Each day she has read 1/6 of the book.
Step-by-step explanation:
Monica has read 5/6 of book .
Each day she read the same number of pages for 5 days
Each day she read 5/6/5= 5/6*5= 1/6
Each day she has read 1/6 of the book.
So that in 5 days it makes
1/6+1/6+1/6+1/6+1/6= 5/6

Linsay was going to visit her grandmother shop at the mall and then return home the route she took was in the shape of a triangle the distance between each patient visit it was 10 miles what type of triangle is formed by the route she traveled?
Answer:
an equilateral triangle
Step-by-step explanation:
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
Area of a triangle = 1/2 x base x height
the perimeter of a triangle = sum of the side lengths
An equilateral triangle is a triangle with three equal sides. the distance travelled her all equal to 10 miles.
