Solve for x. Show your work.
puteri [66]
So, these are actually pretty simple once you learn the equality used to solve for "x" and when to implement this method. You can use this equality to solve for a segment "x" anytime that two secant lines cutting through a circle come from the same point outside the circle. 

Secant: by geometric definition is just a straight line that cuts a curve into multiple pieces.

I did one of them for you hopefully you can use my work for "a" to help you solve for "b".  For a. I got x=7.

Complete Question

The complete question is shown on the first uploaded image

Answer:

The coefficient  is  r  =0.81

Step-by-step explanation:

From the question we are told that

      cov(x, y )= 1260

      s_x^2 =  1600

     s_y^2  =  1225

Generally the coefficient of determination is mathematically represented as

      r  = [ \frac{cov(x,y)}{ \sqrt{s_x^2} *  \sqrt{s_y^2} }   ]^2

substituting values

      r  = [ \frac{ 1260}{ \sqrt{1600} *  \sqrt{1225} }   ]^2

     r  =0.81
