Most linear systems you will encounter will have exactly one solution. However, it is possible that there are no solutions, or infinitely many. (It is not possible that there are exactly two solutions.) The word unique in this context means there is a solution, and it's the only one.
Answer:
3/4, 0.73, 1/4, 0.24
Step-by-step explanation:
1/4=25/100=0.25
3/4=75/100=0.75
I think this is what your doing am assuming . forgot but just put -3a+1a solve it and then do -1+2 and you got your anwser
I believe this is your answer is I understand correctly.
(1/x^3)/(3/x^2)=x^2/3x^3
x^2/3x^3=1/3x
Divide 6 by 75:
6 / 75 = 0.08 = 8%
8% of the trees are at least 30 feet tall.
100% - 8% = 92%
This means 92% of the trees are under 30 feet.
