  10.4

Step-by-step explanation:

The Pythagorean theorem applies to the sides of this right triangle.

  x² + 6² = 12²

  x² +36 = 144 . . . . find the squares

  x² = 108 . . . . . . . . subtract 36

  x = √108 . . . . . . . take the square root

  x ≈ 10.4

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
