Which word best describes the degree of overlap between the two data sets?
solniwko [45]
Hey there! :D

When looking at the data sets, notice that they only overlap in the middle, by a few points. There is overlap, so it isn't "none", it isn't much, so it wouldn't be "high" or "moderate". It would be considered low overlap. 

I hope this helps!

Help please with math
quester [9]
Working with fractions, huh? They are not as hard as you may think. 

Just think:

1/4 = 2/8

3/4= 6/8

So...

9 3/4 = 9 6/8

Step 2.
 
9 + 1 = 10

6/8 + 1/8 = 7/8

Step 3

10 and 7/8

Step 4

Simplest answer 
 10  7/8, 
(can't get more simplified than that)

Hope this helps! :)

Solve |2x - 1| + 3 = 6.
umka21 [38]

Answer:

x =2                         x = -1

Step-by-step explanation:

|2x - 1| + 3 = 6.

Subtract 3 from each side

|2x - 1| + 3-3 = 6-3

|2x - 1|= 3

An absolute value has two solutions, one positive and one negative

2x-1 =3                   2x -1 = -3

Add 1 to all sides

2x-1+1 =3+1             2x-1+1 = -3+1

2x = 4                      2x =-2

Divide by 2

2x/2 = 4/2                 2x/2 = -2/2

x =2                         x = -1
