<h3>
Answer: P(3) = 0.20</h3>
====================================================
Explanation:
The Poisson PDF value is given by the function
P(x) = ( e^(-mu)*mu^x )/(x!)
where the exclamation mark indicates a factorial
In this case, mu = 4, so we can update the equation into
P(x) = ( e^(-4)*4^x )/(x!)
Now plug in x = 3 to finish off the problem
P(x) = ( e^(-4)*4^x )/(x!)
P(3) = ( e^(-4)*4^3 )/(3!)
P(3) = 0.1953668148129
P(3) = 0.20
Note: The 'e' is a special constant which is approximately e = 2.718, similar to how pi = 3.14 is a constant used often.
<h3>Write an equation that will match the story problem</h3>
<em><u>Solution:</u></em>
Given that,
Osso has $ 5
He buys 9 peppermints for $0.15 each, and some sour candies
Each sour candy cost $0.25
The equation is:
Let the number of sour candies bought be "x"
Then,
Remaining amount after buying pepper mint =
Each sour candy cost $0.25
Now the number of sour candies bought is:
x = 14.6
Thus osso can buy 14 sour candies
Thus the equation that will match the story problem is:
Where, "x" means number of sour candies bought
Answer:
-10+12=2;+2
Step-by-step explanation:
As the midpoint is a point on the perpendicular line, we can solve by eliminating the other equations, like this:
Check if the point (-1,-2) is on the line y=-4x-4:
-4(-1)-4=0 is differente from -2.
-4(-1)-6=-2, so (-1,-2) is on the line y=-4x-6.
We check also for the other equation like this:
Third equation: (-1)-4 = -5 not equal to -2.
Fourth equation: (-1)-6=-7 not equal to -2.
So the correct answer is the line y=-4x-6
