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
Answer: C
Step-by-step explanation:
30 km/s x 60 = 1800 (1 minute)

Answer:
149
Step-by-step explanation:
Just by guessing you can see that they are 7 and 10
