The first one
Step-by-step explanation:
the other ones are not statistical
I hope this helps!
Diagonal of a square is √2a
so,
√2 a = 12
a= 12/√2
and.. perimeter of a square is 4a
so,
peri = 4*12/√2
= 48/√2

The answer to this question is 100% B: y=2x+7 I hope this helped you! :)
Answer:
The possible numbers of songs that you can burn onto the CD is 11.
Step-by-step explanation:
The total storage capacity of CD = 70 minutes
Storage already used = 25 minutes
Hence, The available storage = Total available storage - Used Storage
= 70 minutes - 25 minutes = 45 minutes
Hence, the CD has 45 minutes storage left.
Now, each song takes up 4 minutes of storage.
⇒ ![\textrm{Total number of songs possible} = \frac{\textrm{Total storage left}}{\textrm{Time taken by each song}}](https://tex.z-dn.net/?f=%5Ctextrm%7BTotal%20number%20of%20songs%20possible%7D%20%3D%20%20%5Cfrac%7B%5Ctextrm%7BTotal%20storage%20left%7D%7D%7B%5Ctextrm%7BTime%20taken%20by%20each%20song%7D%7D)
= ![\frac{45 minutes}{4minutes } = 11.25](https://tex.z-dn.net/?f=%5Cfrac%7B45%20minutes%7D%7B4minutes%20%7D%20%20%3D%2011.25)
⇒The number of songs possible = 11.25 ≈ 11
Hence, the possible numbers of songs that you can burn onto the CD is 11.
