(Choice A)
A
The model indicates that students who spent 232323 hours on video games will average approximately 000 hours spent on homework.

(Choice B)
B
The model indicates that students who spent 000 hours on video games will average 232323 hours spent on homework.

(Choice C)
C
Joyce spent approximately 232323 hours on homework.

(Choice D)
D
Joyce spent approximately 232323 hours on video games.
A graph plots Hours spent on homework, from 0 to 24, in increments of 2, versus Hours spent on video games, from 0 to 14, in increments of 2. Dozens of points fall diagonally in a relatively tight, narrow cluster between (0.5, 23.8) and (14.1, 3.1). A regression line falls diagonally through the center of the cluster from (0, 23) to (15, 3). All values estimated.

The fraction of the image in blue with respect to the <em>entire</em> hexagon is \frac{1}{3}.

<h3>Estimation of the ratio of the shaded region area to the entire area</h3>

Initially we proceed to create auxiliar constructions , represented by red line segments, to re-define the hexagon as a sum of standard figures. According to the figure, we find two types of triangles (type-1 and type-2), and the following relationship between the two types:

A_{1} = A_{2} (1)

Where:

  • A_{1} - Area of a type-1 triangle.
  • A_{2} - Area of a type-2 triangle.

The formulae for the area of the shaded region (A_{s}) and the <em>entire</em> hexagon (A_{h}) are, respectively:

<h3>Shaded region</h3>

A_{s} = 2\cdot A_{1} + 4\cdot A_{2} (2)

<h3>Entire hexagon</h3>

A_{h} = 8\cdot A_{1} + 10\cdot A_{2} (3)

And the fraction of the image in blue is:

\frac{A_{s}}{A_{h}} =  \frac{2\cdot A_{1}+4\cdot A_{2}}{8\cdot A_{1}+10\cdot A_{2}}

\frac{A_{s}}{A_{h}} = \frac{6\cdot A}{18\cdot A}

\frac{A_{s}}{A_{h}} = \frac{1}{3}

The fraction of the image in blue with respect to the <em>entire</em> hexagon is \frac{1}{3}. \blacksquare
