Agroup of 22 students participated in a race. their scores are below:
score (points) 4–5 6–7 8–9 10–11 12–13
number of students 3 5 8 4 2

would a dot plot or a histogram best represent the data presented here? why?

$32,660

step-by-step explanation:

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
