Give 3 numbers that would work for the value of x if x ≤ -2

9 8 5 are the numbers.

4 5 6 are alll numbers

0.75% because if 4% is corresponding to 80%, then 40%=2% and 20%=1% and 15+5=20 so the 15% and 5% added up have a 1% defect rate. and then 10%=0.5% and 5%=0.25% so the 5% is equal to 0.25% and then subtract 0.25% from 1% and you get 0.75%. i'm really sorry if this is super confusing for you, but it's the way my brain works. lol!
