Multiplication property of equality can be used to solve:
Step-by-step explanation:
First of all, lets define the multiplication property of equality
The multiplication property of equality states that if one side of an equation is multiplied with any number the other side is also multiplied with the number.
Given equations are:
By observing the equations we can see that only third equation has a fraction in it so it has to be multiplied with -2 for solution
Hence,

Answer:
a. 0.098
b. 4.41
c. Yes, it does.
Step-by-step explanation:
a.
The Poisson distribution's equation is:
P(x) = (nˣ*e⁻ⁿ)/x!
where P is the probability, n is mean number, and x the number of the event happens, so:
P(3) = 0.098
b.
For 45 years, the years that are expected to have 3 hurricanes are
P(3) * 45 = 0.098*45 = 4.41
c.
Yes, it does. The Poisson distribution works well because the observed value of the number of years that 3 hurricanes occur is 45-year period is very close to the calculated value.
