1133.54 in.^2

Step-by-step explanation:

The answer is the area of the circle which is in white inside the square. We are not looking for the shaded area.

A = (pi)r^2

r = d/2 = 38 in./2 = 19 in.

A = (3.14)(19 in.)^2

A = (3.14)(19 in.)(19 in.)

A = 1133.54 in.^2

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
