Flying against the wind, an airplane travels 3240 kilometers in 4 hours. Flying with the wind, the same plane travels 6540 kilometers in 6 hours. What is the rate of the plane in still air and what is the rate of the wind?
km

the circle one

figure c

step-by-step explanation:

hope this .

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
