Me i need a building with a height of 21 m casts a shadow that is 24 m long while a taller building casts a 96 m long shadow. what is the height of the taller building?

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

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
