Complete Question
The Brown's Ferry incident of 1975 focused national attention on the ever-present danger of fires breaking out in nuclear power plants. The Nuclear Regulatory Commission has estimated that with present technology there will be on average, one fire for every 10 years for a reactor. Suppose that a certain state has two reactors on line in 2020 and they behave independently of one another. Assuming the incident of fires for individual reactors can be described by a Poisson distribution, what is the probability that by 2030 at least two fires will have occurred at these reactors?
Answer:
The value is
Step-by-step explanation:
From the question we are told that
The rate at which fire breaks out every 10 years is
Generally the probability distribution function for Poisson distribution is mathematically represented as
Here x represent the number of state which is 2 i.e
Generally the probability that by 2030 at least two fires will have occurred at these reactors is mathematically represented as

Answer:
The translation statement is given by:
After the translation, the coordinates of vertex A is (-2,6).
Step-by-step explanation:
Given :
Vertices of a triangle ABC are:
A(−3, 4), B(4, −2), C(8, 3)
The triangle is translated 2 units up and 1 unit right.
To find the co-ordinates of point A after translation.
Translation rules.
For shift of units up, the translation is given as:
For shift of units right, the translation is given as:
So, it says the triangles is translated 2 units up and 1 unit right.
The translation statement is given by:
So, co-ordinates of point A after translation is given by :
After the translation, the coordinates of vertex A is (-2,6).
