Answer: There are 24 possible sequences of assembly.
Step-by-step explanation:
Since we have given that
Number of wires which need to be attached to a circuit board = 4
We need to find the number of possible sequences of assembly that must be tested.
Using multiplication rule of counting we get that,
Number of possible sequences of assembly is given by

i.e. there are four choices for the first wire, three choices for the second wire, two choices for the third wire, one choice for the fourth wire.
Hence, there are 24 possible sequences of assembly.

Answer:
6
Step-by-step explanation:
Listing the divisors of each number
50 : 1, 2, 5, 10, 25, 50
15 : 1, 3, 5, 15
The common divisors are : 1, 5
Their sum = 1 + 5 = 6
Answer:
5.5 Hours
Step-by-step explanation:
Currently, the equation is 60=8.50h+13.25 and h stands for the hours that Sammie worked. So, you need to solve for h by first subtracting 13.25 (his tips) and getting the amount that he received for the hours that he worked.
You should now have 46.75=8.50h
Our final step, is to divide 46.75 by 8.50 to get h by itself and determine the total hours that Sammie worked.
In the end, you should come out with h=5.5, which means that Sammie worked 5.5 hours.
