Step 1

The given model is Number of students$=0.0112{x}^{2}+0.4663x+1.513$

Using this model, we can approximate the number of students (in millions) taking at least one online college course between the period 2002 and 2012.

Here,$x=0$ corresponds 2002

$x=1$ corresponds 2003.

So,$x=12$ corresponds 2012.

So, substituting$x=12$ in the given model, we get the approximate number of students (in millions) who took at least one online college course in 2012.

So, Number of students in$2012=0.0112{\left(10\right)}^{2}+0.4663\left(10\right)+1.513$

$=0.0112\left(100\right)+4.663+1.513$

$=7.296$ millions

Therefore,$7.296$ million students took at least one online college course in 2012.

The given model is Number of students

Using this model, we can approximate the number of students (in millions) taking at least one online college course between the period 2002 and 2012.

Here,

So,

So, substituting

So, Number of students in
