Yumi and juan pick up litter along the highway at the same rate. yumi picks up litter for 3 miles and takes two hours longer than juan, who picks up litter for 2 miles. if it took juan x hours, how long did it take yumi? a. 1 hour 20 minutes b. 3 hours 20 minutes c. 4 hours d. 6 hours

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

8.3 and the 3 is repeating

hope this .
