When testing for current in a cable with sixsix color-coded wires, the author used a meter to test threethree wires at a time.

Virty [35]

Answer:

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:

$_6C_3=\frac{6!}{(6-3)!3!}\\_6C_3=\frac{6*5*4}{3*2*1}\\_6C_3=20$

20 tests are required to verify every possible pairing of three wires.

Can someone help me understand what I did wrong with these two

-3/4 is a rational number because it can be written as a whole number over 100 (-75/100)
Square roit 2 is less than square root 3 as 2 is a smaller number than 3
17 is close to 16, which has an exact square root of 4, so square root 17 rounded to the nearest whole number is 4
