If the data below were represented with a stem-and-leaf plot, a stem of 2 would have how many leaves?
17, 22, 53, 74, 42, 26, 93, 15, 67, 29, 50
A. 2
B. 3
C. 4
D. 5

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

i would say true? if the unit was informational and it "refreshed your understanding", then true.
