When the order of selecting r individuals out of n individual , we use permutations.
The number of permutations of r things taking out of n things is given by :-
Given : There are 135 people and three door prizes .
i.e. n= 135 , r= 3
Then, the total number of ways =
Hence, there are 2405970 ways to distribute door prizes of $7,500, $750 and $75 .
You can plug 1350 or less watts without overloading the circuit.
Step-by-step explanation:
Given,
Circuit overloads at = 2400 watts
Electricity consumed by portable heater = 1050 watts
Let,
x be the additional number of watts you can plug in.
Portable heater + additional watts ≤ Overloading limit
1050 + x ≤ 2400
Subtracting 1050 from both sides
You can plug 1350 or less watts without overloading the circuit.
