B. 6.3 Because, for a triangle, you can use the angles to figure out the length. You can also tell that it can’t be D or A because it’s not longer than the base and it’s not small enough to be C.
Let's build the equation counting how many x's and 1's are there on each side.
On the left hand side we have 5x's and 8 1's, for a total of 
On the left hand side we have 3x's and 10 1's, for a total of 
So, the equation we want to solve is

Subtract 3x from both sides:

Subtract 8 from both sides:

Divide both sides by 2:

Answer:
8%
Step-by-step explanation:
9+3=12 (total number of students that write left handed)
90+60=150 (total number of 6th graders)
12/150 x 100% = 8%
Nooooooooooooooooooooooooooooooooooooo
Q1 = (19 + 20)2 = 19.5
Q2 = 26
Q3 = (32 + 33)/2 = 32.5
IQR = 32.5 - 19.5 = 13
13 * 1.5 = 19.5
outliers are : 19.5 - 19.5 = 0...anything below 0
32.5 + 19.5 = 52...anything above 52
there are no outliers <====
