Answer :
Answer:
13, 20 and 24.
Step-by-step explanation:
if the mean is 19 then x + y + z = 57
Range = 11 so we can write
y - x = 11
Adding to the first equation we have:
2y + z = 68
As each number is less than 25
y and z could be
24 and 20
and that would make x = 57 - (24 + 20) = 13
That fits in with the range being 11 ( as 24 - 13 = 11)
Answer is 13, 20 and 24.
