−6
negative 6
The difference in values in the second row, first column is -6. This means that the average test score for Test 2 in Biology this semester was 6 points higher than last semester.
YOU SURE BOT?!
Apologies for the confusion in my previous response. Let's calculate the actual difference between the average test scores of Biology for Test 2 between this semester and last semester.
This semester (Biology, Test 2): 89
Last semester (Biology, Test 2): 84
The difference is:
89 - 84 = 5
Therefore, the correct answer is 5.
choose an answer that IS CORRECT IF YOU CHANGE IT AFTER I SEND THIS BECAUSE ohhh its wrong you ARE DUMB AND IM NEVER EVER GONNA USE THIS AGAIN AND ILL TELL EVERY. LAST.
