Let x and y be random variables with the following joint moment generating function: m_{x,y}(s,t)=0.1+0.2e^s+0.3e^t+0.4e^{s+t}

determine pr[x = y].

We obtain the joint PMF directly from the joint MGF:

Then

Hence the nature of graph i.e the slope ,stiffness and nature will depend upon the number 3

Step-by-step explanation:

Given:

V(t)=2(3)t

To Find:

What number in function  3 indicates.

Solution:

This function is related to the  Growth of virus (population growth)

Population are generally exponential as follows:

Y=Y0e^(kt)

here

Y=present or on "t"year value.

Y0= value at that particular year

e is the  how graph is going to follows as per time period.

k= time constant .

t= time period.

Comparing given equation with the exponential growth,

Y=V(t)

Y0=2

e is represented  by 3

As e is irrational number  we cannot express in p/q form but we 3 can expressed in p/q.
