Answer: N = 4845
Therefore, the number of different combinations of programs that can be run at the same time is 4845.
Step-by-step explanation:
In combination, the order of the programs does not matter.
nCr = n!/r!(n-r)!
For the case above we want to determine the number of combinations of 20 programs on a 4 cores computer.
N = 20C4 = 20!/4!(20-4)!
N = 20!/4!16!
N = (20×19×18×17×16!)/(4!×16!)
N = 4845

Answer:
$135
Step-by-step explanation:
Given data
Amount paid for new surfboard= $81
Percentage of the savings paid= 60%
Let the amount of the savings be x
Hence
60% of x= 81
60/100*x= 81
0.6x=81
x= 81/0.6
x=$135
Hence his savings was $135
