So the second train is going 1/5 the speed of the first train, and sooo it’ll probably take 3.25 or 3.5 hours I think
You would write it as (1/10^12)
any negative exponent does the same thing
ex: x^-1 turns into (1/x^1)
Answer:9.34×10^1
Step-by-step explanation:
To simplify 467000×0.0002 in scientific notation
We get
467000×0.0002
=93.4
=9.34×10^1
Answer:
6.25%
Step-by-step explanation:
To know the final probability that this has happened, we must multiply the probability of each event, they tell us that the probability that it is a girl is 1/2 and this happened 4 times, therefore:
(1/2) ^ 4 = 0.0625
that is, the probability that 4 girls are born is 6.25%
an unusual probability is considered when it is less than 5%, therefore, although it approaches this figure, it is not unusual
