I have a question on math if I start to look for a object hidden by making the center of a field as (0,0), with coordinates giving distances in yards. Coordinates to the north or east are positive and coordinates to the south or west are negative. And I find nothing at (-12,8), so I try a likely-looking spot 3 yards to the east and 11 yards to the south of the first spot. Can you explain what are the coordinates of the second spot?
Is it (-9,19) ?
Your first coordinate is correct as -9
for the 2nd, you are at 8 and are going south for 11
so 8-11 = -3
your new point is (-9,-3)
South okkkkk I got it thanks. : )
Ira makes an A on 80% of his tests. In the next week, Ira has 5 final exams. He wants to determine the probability that he makes an A on 4 of the 5 tests.
