Answer:
Step-by-step explanation:
A negative exponent in the numerator is the same as a positive exponent in the denominator, and vice versa.
... a^-b = 1/a^b . . . . . for any value of b, positive or negative
The exponent of a product is the sum of the exponents:
... (a^b)(a^c) = a^(b+c)
___
Applying these rules, you have
... = 2/(3x^4·x·y) = 2/(3x^(4+1)·y) = 2/(3x^5·y)
Answer:
Therefore the chance that a particular square inch is not by any drops during a given 10 second period is .
Step-by-step explanation:
Poisson distribution:
Given that rain is falling at an average rate 30 drops per square inches per minutes.
A reasonable choose of this distribution is Poisson distribution .
Let the area be a square inch.
Here = average rate of rain drop × area
=(30×a)= 30 a
t = 10 second
.
Therefore,
Therefore the chance that a particular square inch is not by any drops during a given 10 second period is .
