Answer:
A: Solve the following.

... Consider two vectors
$\begin{align}
u &= ( \sqrt a , \sqrt b, \sqrt c )\\
v &= (\frac{1}{\sqrt a} , \frac{1}{\sqrt b}, \frac{1}{\sqrt c})\\
u.v &= ( \sqrt a , \sqrt b, \sqrt c ) (\frac{1}{\sqrt a} , \frac{1}{\sqrt b}, \frac{1}{\sqrt c})\\
u.v &= (\frac{ \sqrt a}{\sqrt a} +\frac{\s ...

Answer:
A: Solve the following.

... Given
$\begin{align}
8x-10y+66 &=0 \\
8x-10y & =-66 - - - -1 \\
40x-18y& = 214 - - - - 2 \\
\sigma x& = 9\\
\end{align}$
To find x&y solve equation 1 & 2, simultaneously, we get,
x=13
y=17
To find r: Suppose, the first equation represent the line of regression of x on ...
