You can easily calculate it
Hello!
There's more than one way in which to check this answer thru estimation. I'd find 6*60 and 6*70 separately, obtaining 360 and 420. It's obvious that Kendra's "390" is between 360 and 420, so it's likely that she's right.
6*65 does indeed equal 390.
-0.83 has the strongest correlation.
