A football team carried out a report to see the impact of stretching on preventing injury. Of the 50 footballers in the squad 32 stretch regularly. Of those who stretch, 4 got injured last year. There was a total of 19 injured players last year. The results can be presented in a frequency tree. What fraction of players who do stretch get injured?

15 / 18

Step-by-step explanation:

19-4= 15

50-32=18

So 15/18 is fraction for injured players that didn't stretch

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.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
