What property is used to change the sum of 18+6 to the equivalent expression 6(3+1)
1 answer:
The distributive property is used to get the equivalent expression
Step-by-step explanation:
The properties on mathematical expressions are used to simplify or elaborate the expressions.
One of the propoerties is distributive properties
The distributive property states that:
Let a, b and c be three integers then
a(b+c) = ab+ac
The property can be used both ways
In given expression
18+6
The distributive property is used to get the equivalent expression

Answer:
The probability that occurrence of 8 in ten minutes is 0.0771.
Step-by-step explanation:
Poisson Distribution:
A discrete random variable X having the enumerable set {0,1,2,.....} as the spectrum, is said to have Poisson distribution with parameter (>0), if the p.m.f is given by
for x=0,1,2,...
= 0, elsewhere
The mean number of occurrences in ten minutes is 5.3.
Here = 5.3 and x= 8
=0.0771
The probability that occurrence of 8 in ten minutes is 0.0771.
