An investor indicates that he will be able to Treble the value of the investment at the end of six years. the interest rate is fixed and compounded monthly. calculate the annual interest rate that the investor has to offer.​

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

you would 18 *0.25 = 4.5
