Step-by-step explanation:

I don't have any questions for you to answer but okay.

13.

To find out the percent you just gotta times 980 by 85 and then divide the product by 100:

(980*85)/100=

83,300/100=

833

14.

To find out the percent of calls you need to do this and simplify

= which is 75%

15.

If 570 is 3/5 or 60% then you can use ratios to find out the whole number.

3:5

570:x

x would be:

(570/3)*5=

190*5=

950

950 students in all

16.

15.5% of 1240 is just (15.5*1240)/100 which is 192.2

17.

I don't want to explain anymore:

(1500*82)/100=123000/100=1230

18.

(5720*3)/100=17160/100=171.6

19.

21/50= 42%

540/1323≈41%

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.
