If the width is 15, and the scale factor from width to length is 3:2, then you will have to divide 15 by 3 to get your original width.
15/3 = 5.
5 is your original width.
To a higher number the six changes value in this number above
This problem has infinitly many solutions
Answer:
digits are: 0, 4, 8. The required number is: 480.
Step-by-step explanation:
→ Let ones digits is 'x', then according to the condition the hundreds digit is 'x+4', and the tens digit is '2(x+4)'.
→ According to the condition the sum of the digits is: x+(x+4)+2(x+4)=12.
→ After evaluation this equation, x=0 - this is ones digit;
→ x+4=0+4=4 - this is hundreds digit;
→ 2(x+4)=2(0+4)=8 - this is ten digit.
a) 
has CDF
where the last equality follows from independence of 
. In terms of the distribution and density functions of , this is
Then the density is obtained by differentiating with respect to 
,
b) 
can be computed in the same way; it has CDF
Differentiating gives the associated PDF,
Assuming 
and 
, we have
and
I wouldn't worry about evaluating this integral any further unless you know about the Bessel functions.
