27.3

Step-by-step explanation:

Total number of students=55

Total number of

left handed students =15

hence, take the % between them

15/55*100=27.2727...%= 27.3%

c) 27.3%

Step-by-step explanation:

% = (part/whole)*100%

part = left handed = 11+4 = 15

whole = all students = 55

% = (15/55)*100% = 27.3 %

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

answer: f = 32.2m

step-by-step explanation: that is the answer
