Consider the four points (10,10), (20,50), (40,20), and (50,80). the least squares line is modifyingabove y with caret equals 7.0 plus 1.1 xy=7.0+1.1x. explain what "least squares" means, using these data as a specific example.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

i belive those are the ones that are under 90 degreese.
