Step-by-step explanation:
The question is incomplete, as the box plot is not attached.
However, the interpretation of the question is to determine the inter-quartile range (IQR) ; this represents the middle 50% of scores
To answer this question, I will make use of the attached box plot.
IQR is calculated as:

and
are represented by the vertical edges of the rectangle in the box plot. [See attachment]
Reading
and
, we have:


The IQR is:


<em>Hence, the range that describes the middle 50% of the attached plot is 13</em>
Answer:
a=
Step-by-step explanation:
vf=vi + at
vf-vi= at
divide both sides by t
=
a=
Beck add like terms so you get
4x^2 -4x-15
lucy factor our negative so you left with -4x^2 +5x -10 +8x^2 -9x -5
simplify 4x^2 -4x -15
therefore both students answers simplify to 4x^2 -4x -15
2x+x=114 (ext. ∠ of △)
3x=114
x=38
