Solving a polynomial inequation
Solving the following inequation:
(x - 8) (x + 1) > 0
We are going to find the sign both parts of the multiplication,
(x - 8) and (x + 1), have when
x < - 8
-8 < x < 1
1 < x
Then we know (x - 8) (x + 1) > 0 whenever (x - 8) (x + 1) is positive
We can see in the figure (x - 8) (x + 1) is positive when x < -8 and x > 1
Then
Answer:B
Answer:
Mean = 19.5
Step-by-step explanation:
Mean = sum of numbers ÷ Amount of numbers
Mean = 
Mean = 
Mean = 19.5
Answer:
4.33
Step-by-step explanation:
1/3=0.33 recuring
4 just eqauls 4
so you add 0.3 recuring to 4
and depending on significant figures it wants you round it ill assume it wants 3 and go 4.33
Anyway the distance is 1.
I give you the graphic of this function
Answer:
It's B, 62.
First, you identify the median, (30,) and use this to identify the first and third quartiles. 2-18 are the first ranges, and 42-81 are the third.
You would need to split the ranges between the first quartile (9) and the third quartile (71).
The interquartile range is the difference between the first and third ranges, making it 62.
