Answer:
x = 2 is the solution of x^3 - x - 6
Step-by-step explanation:
(x^3) - x - 6 = 0
If x = 2,
--> (2^3) - 2 - 6
= 8 - 2 - 6 = 8 - 8 = 0.
Box and whiskers plots use five number summaries. The first number is:
1:Minimum
2.Quartile 1
3.Mean
4.Quartile 2
5.maximum
Quartile are simple to get.
If your set of numbers is:
2,3,3,6,8,8,11
Then find the mean
2 3 3 |6| 8 8 11
Find the mean of the left side of of mean.
2 |3| 3 3 =Quartile 1
Then the right side
8 |8| 11 8 =Quartile 2
-----------------------------------------------
Your 5 number summary is 2,3,6,8,11
Plot them on the number line, but put a line above where the dot would go. take the 3 middle lines and connect to make a box. The lines on the outside of the box are the whiskers, AKA distributed data.
Answer:
Step-by-step explanation:
Use the distance formula between points to find all sides:
AB=
BC=
CA=
This is a 45° 45° 90° triangle, where two of the sides are equal and the other side is the first two sides times 
, so yes, it is a right triangle.
