Answer:
12.5%
Step-by-step explanation:
There is only one number 5 from a total of 8 parts.
1 out of 8.
1/8 = 0.125
P(5) = 12.5%
Answer:
The probability that exactly one switch is good is

Step-by-step explanation:
The probability that a switch is defective is:

The probability that a switch is not defective is

Therefore, if two switches are selected, the probability that exactly 1 is good is:



Answer:
B
Step-by-step explanation:
Look at the graph, it passes to (0,3), so you need to replace that coordinate into A,B,C,D. Then you can see, there is only B and C satisfies.
and

Next step, you can see when x approach to infinite then Y approach to 0.
Hence, we will take limit of B and C, if limit B or C equals to 0 then we will choose.

and
![\lim_{x \to \infty} {[(\frac{1}{2})^x+2]}= \lim_{x \to \infty} {(\frac{1}{2})^x}+ \lim_{x \to \infty} {2}=0+2=2](https://tex.z-dn.net/?f=%5Clim_%7Bx%20%5Cto%20%5Cinfty%7D%20%7B%5B%28%5Cfrac%7B1%7D%7B2%7D%29%5Ex%2B2%5D%7D%3D%20%20%5Clim_%7Bx%20%5Cto%20%5Cinfty%7D%20%7B%28%5Cfrac%7B1%7D%7B2%7D%29%5Ex%7D%2B%20%5Clim_%7Bx%20%5Cto%20%5Cinfty%7D%20%7B2%7D%3D0%2B2%3D2)
We can see that only B is satisfied.
All it does is move from its original position. Translation does affect its side lengths angles shape or size.
