Question

This table shows data on heating oil use for two years in three adjacent buildings on Spring Street.

Answer 1

a. Write a matrix H to represent the data.
b. Find element ___. What does this element represent?

Answer 2

the blank is \[H _{2,1}\]

Answer 3

I think the matrix would look just like the table, but without the column and row labels... just the data... it would have 2 columns and 3 rows.

I think H_21 (the missing element) is row 2, column 1... "982"

Answer 4

not 100% sure, but that seems sort of reasonable.
