Answer:
4) 0
5) 30.5 and 60.5
6) 30.5 through 80.5
Step-by-step explanation:
The box plot is split into 4 parts, the first 25% of it (1/4 of 100) is 0.
Q stands for quarter (1/4) so Q1=30.5 because of where the first dot hits, and Q3=60.5 because of where the 3rd dot hits.
The dot plot goes from 30.5 through 80.5.
I hope this makes sense and helps you!

Answer:
- 4
- -2
- 4
- 2
- -2±√2
Step-by-step explanation:
In order to fill the first blank, we need to look at the second line to see what the coefficient of x is.
1. x² +<u> </u><u>4 </u>x +2 = 0
The constant is subtracted from both sides to get the second line.
2. x² +4x = <u> -2 </u>
The value that is added on the third line is the square of half the x-coefficient: (4/2)² = 4
3. x² +4x +<u> 4 </u> = -2 +4
On the fourth line, the left side is written as a square, and the right side is simplified. The square root is taken of both sides.
4. √(x +2)² = ±√<u> 2 </u>
Finally, 2 is subtracted from both sides to find the values of x.
5. x = <u> -2 ±√2 </u>
