Answer:
-3x=-3
x= 1
Step-by-step explanation:
Around 150 rotations
I rounded the radius to feet which is 1 foot. Then you have to get the diameter which is 1x2=2. The diameter is 2 feet. Now for the circumference, we multiply 2 by 3.14(which is pi). The answer to that is 6.28, and since we are rounding it, we get 6 feet. However, we are traveling 900 feet. Divide 900 by 6 and get 150.
All times. The numbers you are dividing with are quotients.
A) Yes, the two events are independent because P(NF|PB) = P(NF).
