Answer:
3.63 * 10^19
Step-by-step explanation:
Given that :
Number of choices to select = 12
Category available :
Blues - 14
Country - 25
Disco - 21
To select an equal number of song for each category ; then 4 songs will be selected from each :
Using combination :
(14C4 * 25C4 * 21C4)
Since the order matters for the 12 selected songs ; it thus requires 12 permutation
Thus ;
(14C4 * 25C4 * 21C4) * 12!
nCr = n! / (n-r)!r!
Using calculator;
14C4 = 1001 ;
25C4 = 12650
21C4 = 5985
12! = 479001600
Hence,
(1001 * 12650 * 5985) * 479001600
= 36301596217286400000
=3.63 * 10^19
In this situation, the -$55 represents the debt of $55,
since this happens when Miguel does not have enough money in his account to
cover payments or transactions. On Thursday, he has a debt of more than $55. The
explanation behind this is if an account balance is less than -55 dollars, it exemplifies
a debt bigger than 55 dollars.
The initial expression is:

So we can solve for r so:
Thats a rectangle .........
