Heya!!
For calculate period, lets applicate formula:
![\boxed{T=1/f}](https://tex.z-dn.net/?f=%5Cboxed%7BT%3D1%2Ff%7D)
<u>Δ Being Δ</u>
T = Period = ?
f = Frequency = 660 Hz
⇒ Let's replace according the formula:
![\boxed{T=1/660\ Hz }](https://tex.z-dn.net/?f=%5Cboxed%7BT%3D1%2F660%5C%20Hz%20%7D)
⇒ Resolving
![\boxed{T=0,0015\ s}](https://tex.z-dn.net/?f=%5Cboxed%7BT%3D0%2C0015%5C%20s%7D)
Result:
The period of that wave is <u>0,0015 seconds.</u>
<u>Δ IMPORTANT Δ</u>
The period is the INVERSE of the frequency. (T = 1 / f).
And the frequency is the inverse of the period (f = 1 / T)
Good Luck!!
Most clouds form in the atmosphere when moist air rises expands and cool to the dew point. When the air above reaches its saturation point, the water vapor is attracted to dust particles which when they accumulate the hold on tho each other and form clouds. Evaporation and condensation is what causes saturation above. When the clouds become heavy enough with moisture, the water then fall to earth as rain. <span />
Answer:
Energy storage plays an important role in this balancing act and helps to create a more flexible and reliable grid system. For example, when there is more supply than demand, such as during the night when low-cost power plants continue to operate, the excess electricity generation can be used to power storage devices.

I hope this helps you out and if your feeling generous plz mark brainliest it helps me a lot thank you:)
The claim of the study is that the average attendance at games is over 523.
Under the claim the null and alternative hypotheses are,
![H_0 : \mu = 523](https://tex.z-dn.net/?f=H_0%20%3A%20%5Cmu%20%3D%20523)
![H_0 : \mu >523](https://tex.z-dn.net/?f=H_0%20%3A%20%5Cmu%20%3E523)
After the performing the test, the test yields the results that, fail to reject the null hypothesis.
As null hypothesis is fail to be rejected, then it can be concluded that there is no sufficient evidence to support the claim that the average attendance at games is over 523.
Therefore the correct answer is C: <em>There is not sufficient evidence to support the claim that the mean attendance is greater than 523.</em>
Answer:
umm what is this language called to be!?
I'm not spamming you
I just have a doubt on that language
that's why
don't mistake me sorry
