What percentage of the students have more than one child in the family?

B

Step-by-step explanation:

25% ?

Step-by-step explanation:

i think it's 25 because i counted up the dots and so theres 20 of them

then i counted the dots over the 1 child thing and there was 5

so i divided 5 by 20 and 0.25

then turned it into a percentage

and got 25%

i hope this helps

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.
