At the Rights of Mankind High School, there is a ratio of two boys to every three girls. If there are 122 boys, how many student are there in total at RoMHS?

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

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
