1,076 (the original thickness) - 22.7 meters (loss per year) * 7 (lost 22.7 meters per year for seven years, so multiply the loss per year by the amount of years) = 917.1 (the size after 7 years)
A.K.A 1,076 - 22.7 * 7 = 917.1
i found this off of the internet so im sorry if its wrong

Answer:
-27a³b⁶+ 8a⁹b¹²
Step-by-step explanation:
In the expression above -27 is a perfect cube of -3, 8 is a perfect cube of 2.
The exponents of a and b in both terms in the expression are divisible by 3.
The cube root of x, that is ∛xⁿ=x∧(n/3) where n is an integer.
Answer:
2.86% probability that there are exactly 3 crimes during the next hour
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.
In a city with 40000 people, each person has a 0.00020 probability of committing a crime each hour.
So 
What is the probability that there are exactly 3 crimes during the next hour
This is P(X = 3).


2.86% probability that there are exactly 3 crimes during the next hour
