Answer:
POISSON DISTRIBUTION
Step-by-step explanation:
When dealing with the number of occurrences of an event over a specified interval of time or space, the poisson distribution is often useful.
Poisson distribution is applicable if:
The probability of the occurrence of the event is the same for any two intervals of equal length.
The occurrence or nonoccurrence of the event in any interval is independent of the occurrence or nonoccurrence in any other interval.
The probability that two or more events will occur in an interval approaches zero as the interval becomes smaller.
Therefore, the appropriate probability distribution is POISSON PROBABILITY DISTRIBUTION.
Step-by-step explanation:
Answer:
1.932 days (or approximatelly 1 day, 22 hours and 22 minutes)
Step-by-step explanation:
The inicial concentration is 60,000, and this concentration triples every 4 days, so we can write the equation:
P = Po * r^t
where P is the final concentration after t periods of 4 days, Po is the inicial concentration and r is the ratio that the concentration increases (r = 3)
Then, we have that:
102000 = 60000 * 3^t
3^t = 102/60 = 1.7
log(3^t) = log(1.7)
t*log(3) = log(1.7)
t = log(1.7)/log(3) = 0.483
so the number of days that will take is 4*0.483 = 1.932 days (or approximatelly 1 day, 22 hours and 22 minutes)
1325 250
------- = -------
x 10
1325(10) = 250x
13250/250 = 250x/250
x = 53
53 gallons are required to travel 1325 miles
hope this helps
