The probability of a student that earned an A on the test is 7/12.
To get a fraction like this, you put the number of students on the left, or the top and the number of students total on the right, or bottom. Then, you simplify your answer. This brings us to 7/12. You cannot simplify any further because the fraction includes a prime number.
I hope this helps!
Its 5 because if u do 3x 5 it equals 15 then subtract 2 it gives u 13
Tan 135 = -1
so rectangular coordinates are (-7 sqrt2, 7 sqrt2)

1.
km=kilometers
kilo=1000
1 km=1000meters
so
1/2km= 1/2 times 1000=1000/2=500meters
2. 1/4 km=1000/4=250 meters
3. 1/5 km=1000/5=200 meters
4. 2/5 km=2000/5=400 meters
5. 3/4 km=3000/4=750 meters
6. 1/8 km=1000/8=125 meters
