Which word best describes the degree of overlap between the two data sets?
a.
high
b.
moderate
c.
low
d.
none

B. moderate

Step-by-step explanation:

Both data set have 14 points and have a similar shape.

There are six differences, at points 11, 13, 15, 16 and 17.  

Taking into account these observations, it is concluded that a moderate degree of overlap exists between the two data sets.

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.

4th option is correct xy=-10

if this was to u plzz mark me the brainliest
