Step-by-step explanation:

the was I understand matrix multiplication, I re-learned tonight so I could be wrong but.....

according to Gaggle matrix multiplication is possible when the number of columns in matrix 1 equals the number of rows in matrix 2

it is called the dot product (that sounds familiar)

first choice has 2 columns and 1 row can't multiple this one

second choice has 1 column and 2 rows can't multiple this one

third choice has 2 columns and 1 row can't multiple this one

fourth choice has 1 column and 1 row This one can be multiplied

Answer:

-0.89 (i think)

Step-by-step explanation:

Since the graph seems to be going downwards from the right, it has a negative correlation. And since the data seems to be pretty close together, the correlation must be strong. That narrows the answer down to -0.89

Answer:
