We need to simplify
First lets factor
=
by applying the radical rule
By applying the radical rule
So
=
=
Now let's factor
By applying the radical rule
,
So
=
So
=
We know that
so
We now have
We know that
So
We now got
We can notice that the numerator and the denominator both got √2 in a multiplication, so we can simplify them, and we get:
All in All, we get
=
Hope this helps! :D

Answer:
The linear regression equation that represents the set of data is:
The predicted number of new cases for 2013 is 1368.
Step-by-step explanation:
The general form of a linear regression is:
Here,
<em>y</em> = dependent variable
<em>x</em> = independent variable
<em>a</em> = intercept
<em>b</em> = slope
Compute the values of <em>a</em> and <em>b</em> as follows:
The linear regression equation that represents the set of data is:
Compute the predicted value of the number of new cases for 2013 (i.e. <em>x</em> = 12) as follows:
Thus, the predicted number of new cases for 2013 is 1368.
