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.
Answer:
y = 384
Step-by-step explanation:
Find an equation that fits the graph
When the value varies directly, y = kx.
Find k by substituting x and y in the equation
y = kx
48 = 18k
k = 48/18
k = 8/3
To find the value of y when x= 144 by substituting x for 144
y = 8/3 x
y = 8/3 (144)
y = 1152/3
y = 384
y is 384 when x is 144.
Answer:
Ok, so with this problem, you would start with the equation 6/10=x/38.
Then, cross multiply:
38(6)=10x
After, you would:
38 x 6 = 228
Then:
228/10
Lastly:
x=22.8m which when rounded equals 23 ft.
