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:

20 tests are required to verify every possible pairing of three wires.
Answer:
<em>y</em> = -6<em>x - </em>2
<em>y </em>= <em>x</em> - 12
Step-by-step explanation:
Slope-intercept equation for line of slope <em>m</em> and <em>y</em>-intercept <em>b</em>:
<em>y</em> = <em>mx </em>+ <em>b</em>
A. <em>m</em> = -6, <em>b</em> = -2
<em>y</em> = -6<em>x - </em>2
B. <em>m</em> = 1, <em>b </em>= -12
<em>y </em>= <em>x</em> - 12
Answer:
The number is 12
Step-by-step explanation:
4 times a number is 8 more than 40
Write the equation
4n=40+8
4n =48
Divide each side by 4 to isolate n
4n/4 = 48/4
n = 12
Answer: -1/2
Step-by-step explanation:
The average rate of change is
. Since a=-1 and b=1. We can plug them into the equation and solve.
![\frac{[1^2-1-1][(-1)^2-(-1)-1)]}{1-(-1)} =\frac{(-1)(1)}{2} =-\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B1%5E2-1-1%5D%5B%28-1%29%5E2-%28-1%29-1%29%5D%7D%7B1-%28-1%29%7D%20%3D%5Cfrac%7B%28-1%29%281%29%7D%7B2%7D%20%3D-%5Cfrac%7B1%7D%7B2%7D)
