The perpendicular bisectors of the sides of AABC intersect at X. If the distance from B to X is 2 squareroot 15, what is the distance from X to A?

45

step-by-step explanation:

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

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
