Percentage yield=(actual yield/theoretical yield) x 100%
= (45/50) x 100%
= 90%
Answer:
False
Explanation:
If the row echelon form of the augmented matrix for a linear system has a row of zeros, then the there must not have infinitely many solution,
we can prove this with an example. Suppose we have an augmented matrix A for linear system with a row of zeros,
1 0 0 1
A= 0 1 0 -2
0 0 1 - 1
0 0 0 0
we get
x1=1
x2=-2
x3=-1
so, system has an unique solution.
we can take inference that the given statement is wrong
