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.
Answer:
w = 
Step-by-step explanation:
The question is 
We can first use distributive property to simplify, the distributive property is 
Thus we have:
<em>Now we combine like terms and simplify to get the final answer for w</em><em>.</em>
Thus, w =
Find the equation of the line through <span>the points (–1, –5) and (4, 5). First, find the slope: m = rise / run = 5/10 = 1/2.
Then the equation is y-5=(1/2)(x-4). If (a,1) is on this line, (a,1) must satisfy the given equation. Let y=1 and solve for x:
1-5 = (1/2)(x-4) Mult both sides by 2 to get -2 = x-4. Then x = -4+2 = -2
So (-2,1) is also on the line.</span>
Answer:
A = 84 
Step-by-step explanation:
To find the area of a trapezoid, use this equation:
a = top base
b = bottom base
h = height
Let's classify all the sides:
a = 4 ft
b = 10 ft
h = 12 ft
Now, let's plug all these into the equation:
Add what's in the numerator
Divide 14 by 2
A = 84 Multiply 7 by 12
So, the area of the trapezoid is 84 .
Hope this helps!!
1) the probability of drawing a white marble is 1 out of 9. purple is 8out of 9
2) the probability of drawing two white marbles is 2out of 9
3) two purple because every time you draw if you put it back in the probability doesn't change
