A. score
Step-by-step explanation:
The correct option is (a) "Total path length". It cannot be negative or zero. Velocity of an object can be negative. If it move in the opposite direction of motion, then its velocity is negative. Acceleration can be negative.
Answer: The required probability is 
Step-by-step explanation:
Since we have given that
Number of spruce tree = 20
Number of maple tree = 50
Total trees = 70
We need to find the experimental probability that the next tree Colleen to get a spruce tree.
So, the probability would be :

Hence, the required probability is 
You would need 3 cups of flour because 1*2 is 2 and 2*3 is 6 and 6 divided by 2 is 3
