5. A 10-foot tent pole has a support rope that extends from the top of the pole to the ground. The rope and the ground form a 30° angle. How long is the rope, and what is the distance from the base of the pole to the spot where the rope is fixed to the ground?
A. length of rope - 17.30
distance - 11.5
B. length of rope - 20.0 Ft
distance - 17.3
C. length of rope 20.0 ft
distance 11.5 ft
D. length of rope - 17.3ft
distance - 20.01

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
