Answer:
Mean=-21.5
Median=-26.5
Mode=-28
Range= -6 to-46
Step-by-step explanation:
Arranging the numbers given either in ascending or descending order. In this case, I used descending order as follows
-6
-11
-17
-25
-28
-28
-39
-46
Mode is the number that occurs more than others. In this case, only -28 appears twice hence it is the mode
The mean is given by adding all the numbers and dividing by the frequency.
The sum of numbers will be -6+-11+-17+-25+-28+-28+-39+-46=-172
Mean=-172/8=-21.5
The median is the number that appears in the middle after arranging the numbers in descending order as above. In this case, two numbers appear in the middle, that is -25 and -28 hence median -25+-28/2=-26.5
The range of numbers id from -6 to-46 as arranged above
Answer: 
Step-by-step explanation:
In order to find the value of "x", it is important to remember that:
We can identify in the figure that:
Then:
Solving for AB:
Now, since there are 360° in a circle, we know that:
Then we can substitute 
into 
and solve for "x". This is:
|a+bi| = √(a² + b²)
-4-√2 i -> take a = -4 and b = -√2
|-4-√2 i| = √[ (-4)² + (<span>-√2)² ]
= </span><span>√[ 16 + 2<span> ]
</span></span><span>= √[ 18 ]</span> = <span>√[ 9 * 2 ]
= 3√2
the absolute value is 3√2</span>
25x3=75
4x12=48
48-10=38

{(3,0),(6,1),(9,2)} because
when you plug in the values you get
3-3=3(0) = 0=0
6-3=3(1) = 3=3
9-3=3(2) = 6=6
