1 answer:

6 0

Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

The probability that the noise level of a wide-band amplifier will exceed 2 dB is 0.05 independently of every other amplifier. C

snow_lady [41]

Answer:

0.980

Step-by-step explanation:

The probability that the noise level of a wide-band amplifier will exceed 2 dB is 0.05

So, probability of success = 0.05

Probability of failure = 1-0.05=0.95

There are 12 amplifiers

We are supposed to find the probability that at most two will exceed 2dB.

We will use binomial distribution

Formula : $P(X=r)=^nC_r p^r q ^{n-r}$

p = 0.05

q = 0.95

n = 12

We are supposed to find the probability that at most two will exceed 2dB.

So, $P(X\leq 2)=P(X=0)+P(X=1)+P(X=2)$

$P(X\leq 2)=^{12}C_0 P(0.05)^0 (0.95)^{12-0}+^{12}C_1 P(0.05)^1(0.95)^{12-1}+^{12}C_2 P(0.05)^2 (0.95)^{12-2}$

$P(X\leq 2)=\frac{12!}{0!(12-0)!} (0.05)^0 (0.95)^{12-0}+\frac{12!}{1!(12-1)!}(0.05)^1(0.95)^{12-1}+\frac{12!}{2!(12-2)!} (0.05)^2 (0.95)^{12-2}$

$P(X\leq 2)=0.980$

Hence the probability that at most two will exceed 2dB is 0.980

Answer:

$?\times1\frac{5}{8}=\frac{1}{3}$ represents what fraction of the trip has Andre completed?

Step-by-step explanation:

Consider the provided information.

Andre is walking from home to a festival that is $1\frac{5}{8}$ kilometers away.

He takes a quick rest after walking $\frac{1}{3}$ kilometers.

Let '?' represents the part of trip completed.

Therefore, $?\times1\frac{5}{8}=\frac{1}{3}$ represents what fraction of the trip has Andre completed?

In n + 10 =40, then what is the value of the expression n - 25?

damaskus [11]

Find n first.

n+10= 40

Subtract 10.

n= 30

Plug in n.

30-25= 5

The answer is 5.

I hope this helps!

Increase or decrease 32 pages to 28 Pages round to the nearest tenth of a percent

Amiraneli [1.4K]

Hello! I would love to help!

Let's start by decreasing 32 pages to 28. How many pages does it take to get from 28 to 32? Let's subtract to find out!

32-28=4

Okay, now we know 28 pages is 4 less than 32.

Now, what percentage did it decrease by? Let's find out by dividing!

4/32=0.125

Let's make that decimal into a percentage by multiplying it by 100.

0.125*100=12.5

So, we now know the answer is...

decreased by 12.5%

Hope this helped! Comment if you have questions!
