The radius of a circular mirror is increased by 2 inches due to its decorative border. This increases the area by 113 square inches. Find the radius of the mirror without the decorative border. Round to the nearest whole number.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

step-by-step explanation:

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
