0.49 is the answer to 7% of 7.000
(x₁,y₁) = (2,-3)
(x₂,y₂) = (2,9)
To determine the slope using two points lie on the line, we could use the following formula
m =

plug in the numbers
m =

m =

m =

m = undefined
The slope is undefined, the line is vertical
If you where to simplify 4/6 you will get an equivalent fraction. So you would find a common numeral between the tw0. In this case it would be 2. So it would be 2/3 cause you would divide each number by two to get 2/3.
This is a Poisson Distribution
Average over 3 months = 2
Average over 1 month = 2/3
Average over 2 months = 4/3 = λ
More than four heavy rainfalls means 5, 6, 7,…
P(5) = (e^-λ x λ^5)/5! = 0.009257
P(6) = 0.002057
P(7) = 0.000392
P(8) = 0.000065
P(9) = 0.000010
P(10) = 0.000001
P(more than 4 heavy storms) = 0.01178 (4sf)
Yes, it will be polynomial.
