HELP please i attached the question

a).  200 species = (4/7) of (All)

Multiply each side by 7 . . . 1400 species = (4) x (All)

Divide each side by 4 . . . All = 1400species/4 . . . All = 350 species

b).  

Birds  =  350 species

Plants  =  600 species

There are more species of plants than of birds in the park.

Because 600 is greater than 350.

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.
