Answer:31t 980kg.
Step-by-step explanation: 1 tonne is 1000kg.
so 40 tonnes is 40000kg.
40 t -8 t =32t. Now we have to remove the 20kg, leaving 31t and 980kg.
Answer:
The average number of days that will pass between measurable rain is 7.5.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
The expected period between the event happening is 
During the dry month of August, one U.S. city has measurable rain on average only 4 days per month. Assume all months have 30 days.
This means that

(a) If the arrival of rainy days is Poisson distributed in this city during the month of August, what is the average number of days that will pass between measurable rain? *

The average number of days that will pass between measurable rain is 7.5.
I would say the answer would be D
