20 tests
Step-by-step explanation:
There are six different wires, and for each test the author picks three, this means that each test is a combination of three out of six wires (₆C₃) . The number of total combinations possible is given by:

1/5
Step-by-step explanation:
The answer is A, C, and D.
If you look at the y values column, you'll notice two spots in the chart where there are 0s for the y value.
Since, in those cases, the numbers only exist on the x-axis, there are called x-intercepts.
You'll also notice that the y-values decrease, meaning that the chart goes down from x=-4 to x=0.
Finally, you'll notice an odd sort of pattern, like the values are a mirror of each other, in between 0 and 1. This means there is a line of symmetry at x= 0.5
If $4000 is the principal, compounded annually at 6%per annum for five years, then-
Amount=principal *(1+rate/100)^5
=4000*(1+6/100)^5
=4000*(53/100)^5
=5352.90
Therefore, Compound Interest =5352.90-4000
=$1352.90
Please recheck the calculation.
