Answer:
A. Infinitely many solutions.
Step-by-step explanation:
The row and column numbers are equal in the echelon. This rows have 0001 numbers which indicates that there is free variable at the end. The reduced row echelon has equal number of rows and columns. There are infinitely many solution as the numbers in the rows are zero ending of the free variable 1. If there is no free variable then there will be no solution.

To find the median, we need to first arrange the data in ascending order but we are already given the data in ascending order.
Therefore, the median is:






Therefore, the median = 1.53
You would distribute, 300 times 80 is 2400 and -3x times 1x is -3x so the equation would be y=2400-3x
