Answer:
Step-by-step explanation:
Given a complex number z = a + bi then the absolute value is
| z | = 
Given
| 5 - 6i | = 
= 
=
Answer:
Step-by-step explanation:
E : -5 , -3
F: 2 , -7
Distance = sqrt( ( 2 -(-5)) * ( 2 -(-5)) + (-7 -( -3)) *(-7 -( -3)) )= sqrt ( 49 + 16 ) = sqrt (65)
Place the values in ascending order first:
4, 10, 10, 11, 12, 12, 12, 12, 13, 13, 15, 15, 17, 18, 19, 20
There are 16 values
IQR is 3/4th term - 1/4th term
The 12th value is 15 while the 4th value is 11
Therefore IQR = 15-11 which is 4
I would say the outlier is 4.
Justification: Figure out the mean with the value of 4 then discount it to see whether the mean is affected by the outlier.
There no other figure but can take a property that is linear pair or linear pair axiom
7x and x+20 lie on the straight line so they will equal to 180. So now we can add them and set them equal to 180 so we can solve for x.
7x + x + 20 = 180
8x + 20 = 180
8x = 160
x = 20.
So the value of x is 20
Hope I helped :)
