There are 5 even numbers and 7 numbers total. So it would be 5/7 because that's how many even numbers there are out of those 7 numbers.
How many seconds are in 4 min 24000
so divide 4
its becomes 6000 thats 1 min.
so divide by 60
it becomes 100
so he has an average speed of 1m/100seconds i think i got lost there
Hint: Draw an xy-plane and think of points in the form (x y).
Hey there! :D
Let's break this up piece by piece.
The first two, let's say that the first boxes represent the bottom of the chart.
The first far left box would be 13.
The next one 9.
Going across, 10 and 11.
Two more up.
7 and 3.
One more across, which is 4.
So, 13, 9, 10, 11, 7, 3, 4 would be the ones you would want to shade.
I hope this helps!

To find the angle use arc tan (-5/-7) which simplifies tips arctan(5/7). arc tan is tan to the power -1, which is also called inverse tan. The heading of the angle, if you drew this out on a graph your angle would be in the third quadrant and therefore the heading is south of west.
