answer: 33 ( approx)
stepbystep 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

stepbystep explanation:
2 over 5
stepbystep explanation:
the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
