Lorraine and Bea are learning to type on a computer keyboard, Lorraine's typing speed is represented by the equation y = 9x where y is the number of
words she types and is the number of minutes, Bea's typing speed is given by the graph

A

Step-by-step explanation:

I took one for the team

step-by-step explanation:

left be aligning the decimal points is required to not required see the number of digits to the right

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
