Answer:

The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.
Step-by-step explanation:
The given expression is 
We factor the left hand side to get:

We divide both sides by: a-b

Observe that the difference of a and b is in the denominator.
The whole is of the form: 
The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.
Answer:
Step-by-step explanation:
Given 
a)
we know that 
therefore 
on integrating we get
c=(1/6640)
b)
on doing the integration we get
=0.37349
c)
marginal density of X is
on doing integration we get
f(x)=(4x+3)/3320 ; 0<x<40
marginal density of Y is
on doing integration we get
d)
solve the above integration we get the answer
e)
solve the above integration we get the answer
f)
Two variables are said to be independent if there jointprobability density function is equal to the product of theirmarginal density functions.
we know f(x,y)
In the (c) bit we got f(x) and f(y)
f(x,y)cramster-equation-2006112927536330036287f(x).f(y)
therefore X and Y are not independent
I think the best way to show the results in a chart format is to put zero to twelve on the y-axis or vertically and zero to one hundred on the x-axis or horizontally. Label the y-axis total per roll and the x-axis roll number.Then plot the coordinates or pairs from the table.
500 let me know if it’s right i’m not the best at math
