Find the measure of variation. Name any outliers. Show all your work.
Giving out tons of points!

Range is 18

Outlier is 2

Step-by-step explanation:

The range is largest number minus smallest number

largest number is 20

smallest number is 2

20-2=18

the outlier is 2 because the closest number is 10 and that is 8 away!

so the outlier is 2

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

ome people is not even worth it to even try it in the air.
