At a manufacturing plant where switches are made, it is a known fact that 2% of all switches are defective. If two switches are
olchik [2.2K]

Answer:

The probability that exactly one switch is good is

P(x) =0.0392

Step-by-step explanation:

The probability that a switch is defective is:

P(D) = \frac{2}{100} =0.02

The probability that a switch is not defective is

P(D') = 1-P(D)=0.98

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

P(1=1)=P (D) P (D ') + P (D') P (D)

P(x)=(0.02)(0.98) + (0.98)(0.02)

P(x) =0.0392

A. Y = 1/3(3)^x<br> B. Y= 3(1/3)^x<br> C. Y= (1/2)^x +2<br> D. Y=(2)^x - 1
Dimas [21]

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.

Y=3(\frac{1}{3} )^{0}=3.1=3.

and

Y=(\frac{1}{2} )^{0}+2=1+2=3

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.

\lim_{x \to \infty} {3(\frac{1}{3})^x=3. \lim_{x \to \infty} {(\frac{1}{3})^x=3.0=0

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

We can see that only B is satisfied.
