Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
85, 91, 83, 78, 79, 64, 81, 97
Ordered data : 78, 79, 81, 83, 85, 91, 97
Mean:
Σx / n =
n = sample size = 8
(64+78+79+81+83+85+91+97) / 8
= 658 / 8
= 82.25
Median = 1/2(n+1)th term
1/2(8+1)th term = 1/2 * 9 = 4.5th term
(4th term + 5th term) /2 = (81 + 83) / 2 = 82
Mode = 85, 91, 83, 78, 79, 64, 81, 97
Outlier:
Lower = Q1 - 1.5(IQR)
Upper = Q3 + 1.5(IQR)
Using a calculator :
Q1 = 78.5 ; Q3 = 88 ;
IQR = (Q3 - Q1)
(88 - 78.5) = 9.5
Outlier :
78.5 - 1.5(9.5) = values < 64.25
88 + 1.5(9.5) = values > 102.5
Hence. Outlier is 64
Removing the Outlier :
Data = 78, 79, 81, 83, 85, 91, 97
Mean = 84.85
Median = 83
Based on the result, the median is the best measure of central tendency for the data:

Find the coordinates of the image's vertices.
6. A triangle with vertices ((-2,4), M(-2, 8), and N(-6, 4) is rotated 90° counterclockwise about the origin.
a. L'(-2,-4), M'(-2, -8), and N'(-6,-4)
b. LT-4,2), M (-8,2), and NY-4, 6)
c. L'44,-2), M'(-8,-2), and N'Y 4, 6)
d. L(4-2), M'(8,-2), and N (4-6)
The coordinates of the triangle after the rotation is L' ( -4 , -2 ) , M' ( -8 , -2 ) and N' ( -4 , -6 )
What is Rotation?The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.
90° clockwise rotation: (x,y) becomes (y,-x)
90° counterclockwise rotation: (x,y) becomes (-y,x)
180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
270° clockwise rotation: (x,y) becomes (-y,x)
270° counterclockwise rotation: (x,y) becomes (y,-x)
Given data ,
Let the triangle be represented as ΔLMN
L ( -2 ,4 ) , M ( -2 , 8 ) , and N ( -6 , 4 )
Now , the rotation angle is = 90° counterclockwise about the origin
Let the coordinates of the rotated triangle be ΔL'M'N'
where , 90° counterclockwise rotation: (x,y) becomes (-y,x)
So , L' ( -4 , -2 ) , M' ( -8 , -2 ) and N' ( -4 , -6 )
Hence , the rotated triangle is L' ( -4 , -2 ) , M' ( -8 , -2 ) and N' ( -4 , -6 )

Does anyone know how to solve this?
Answer:
The correct option is c.
Step-by-step explanation:
Given that,
u = 7i+4j and v = 2i-3j
We need to find the product of u and v. The dot product of two vectors is given by :
[tex]u{\cdot}v=(7i+4j){\cdot} (2i-3j)\\\\=(7i)(2i)+(4j)(-3j)\\\\=14-12\\\\=2[/tex]
So, the dot product of u and v is equal to 2.

∠10 + 12(3) = 46°
∠15(3) + 1 = 46°
Step-by-step explanation:
the angles are equal because they are corresponding angles
(10+12x) = (15x+1)
reduce:
3x = 9
x = 3
10 + 12(3) = 46°

Answer:
b = 76°
Step-by-step explanation:
Hi there,
It is important to know that the sum of all the angles in any triangle equals 180°.
For this problem, we can write the following equation:
32° + 72° + b° = 180°
104° + b° = 180°
b° = 76°

Answer:

Step-by-step explanation:
Just Distribute :)
Answer:
48x-20xy+4xz
Step-by-step explanation:
You need to distribute the 4x to the rest of the equation so the equation will become 48x-20xy+4xz, this is because 4x * 12 = 48x and 4x*-5y =-20xy and it's xy because x comes before y in the alphabet and then lastly 4x * z same thing it's gunna be xz, so the answer is 48x-20xy+4xz.

find the value of w please
Answer: w = 136
Step-by-step explanation:
Use the triangle angle sum theorem which states the interior angles of a triangle sum to 180.
14+30+w= 180. Combine like terms.
44+w= 180. Subtract 44 from both sides.
w= 136
Answer:
136°
Step-by-step explanation:
Triangles always equal 180°, so add up the given numbers (in this case, 14 and 30 to get 44) then subtract from 180 to get your answer. Hope this helps!!!

Answer:
12x + 3 + 7x - 13 = 180
Step-by-step explanation:
Q and R are Same Side Interior Angles
If you add any two same side interior angles for a trapezoid, they will equal 180 degrees.
Therefore, 12x + 3 + 7x - 13 = 180 degrees
Answer:
12x + 3 + 7x - 13 = 180
Step-by-step explanation:
The top and bottom sides of the trapezoid are parallel, but the sides are not. This means that the two angles that we are trying to find cannot be equal. In this case, this can only mean that both sides can be combined to complete a 180 degree angle. This can also be determined since they are supplementary angles, or angles that are adjacent to the opposite side of another base.
