Answer:

Step-by-step explanation:

<u><em>Q 4.</em></u> (25m + 25m) ÷ 25 sec. = <em>2 m/sec.</em>

<u><em>Q 5.</em></u> This question belongs to Physics and not Mathematics!!!

Wavelength (lambda) = Velocity (v) ÷ Frequency ( sec^{-1} or Hz )

f = v / (lambda)

f = 3 / 2 = <em>1.5 (Hz)</em>

<u><em>Q 6.</em></u> 0.060 ÷ 2 = <em>0.030 m</em>

YALL I NEED HELP ASAP!!
Elodia [21]

Answer:

32

Step-by-step explanation:

You use angle chasing. Since a triangle's angle has to add up to 180, the other angle is 180-79-69. This gives 32. So angle E is 32 degrees. Since they are parallel, that means that E equals to D. That means that D is 32, so 32 is now the answer.

HAPPY NOW BRAINLY? I JUST DIDN'T ADD AN EXPLANATION ON THE OTHER ONE AND YOU DELETED IT! I GOT BRAINLIEST!  HE STILL GOT THE ANSWER ANYWAYS.

The CPU of a personal computer has a lifetime that is exponentially distributed with a mean lifetime of six years. a) What is th
amm1812

Answer: Our required probability is 0.39.

Step-by-step explanation:

Since we have given that

X be the exponentially distributed with mean life = 6 years

So, E[x]=6

\dfrac{1}{\lambda}=6\\\\\lambda=\dfrac{1}{6}

So, our cumulative distribution function would be

F(x)=1-e^{-\lambda x}

We need to find the probability that the CPU fails within 3 years.

P(X

Hence, our required probability is 0.39.
