Step-by-step explanation:
Answer: rectangles all have two parralel sides and all they all have 4 right angles.
Step-by-step explanation:
The length of the line segment AB where
![A(x_A;\ y_A)](https://tex.z-dn.net/?f=A%28x_A%3B%5C%20y_A%29)
and
![B(x_B;\ y_B)](https://tex.z-dn.net/?f=B%28x_B%3B%5C%20y_B%29)
![|AB|=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}](https://tex.z-dn.net/?f=%7CAB%7C%3D%5Csqrt%7B%28x_B-x_A%29%5E2%2B%28y_B-y_A%29%5E2%7D)
We have:
![A(1;\ 6);\ B(11;-4)](https://tex.z-dn.net/?f=A%281%3B%5C%206%29%3B%5C%20B%2811%3B-4%29)
subtitute
![|AB|=\sqrt{(1-11)^2+(6-(-4))^2}=\sqrt{(-10)^2+10^2}=\sqrt{100+100}\\\\=\sqrt{100\cdot2}=\sqrt{100}\cdot\sqrt2=10\sqrt2\approx14.1](https://tex.z-dn.net/?f=%7CAB%7C%3D%5Csqrt%7B%281-11%29%5E2%2B%286-%28-4%29%29%5E2%7D%3D%5Csqrt%7B%28-10%29%5E2%2B10%5E2%7D%3D%5Csqrt%7B100%2B100%7D%5C%5C%5C%5C%3D%5Csqrt%7B100%5Ccdot2%7D%3D%5Csqrt%7B100%7D%5Ccdot%5Csqrt2%3D10%5Csqrt2%5Capprox14.1)
Answer: b. 14.1
The probability that one switch fails is 1 from 10. According to this the probability is 1/10=0.1.
If you need to have only 1 switch from million to fail, this means that you need the probability 1/1000000=0.000001.
<span>In order to have this probability of one switch failing you will need 1000000 (million) switches.</span>
Answer A
