Kenny likes to count his money by tiling it on his table as shown. The diameter of a quarter is 24.26 mm. Find the area of the t
1 answer:
First we have to assume that each quarter touched each other. Hence the area of the table not covered by the coins (A) is equal to the total area of the table (At) minus the total area of the coins (Ac). Coins are circle, so 
and r =24.26mm. The area of one coin is then 1848.98mm^2. Hence the equation is A = At - xAc where x is the number of coins.

Answer:
steps 4 and 5
Step-by-step explanation:
When we look at example, we can see that we have :
-6r=57
So we divide by -6 and we got
So, our final answer is steps 4 and 5
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.
