Step-by-step explanation:
No of prime number = 4 ( 3 , 5 , 7 , 11)
P ( prime number) = 4/12
= ⅓
It depends upon the shape. But perimeter in general is the sum of the outside measure. Here, for whatever the shape is, the perimeter is 26
Let's assume the frequency of sound be f and wave length is w.
Given that, the frequency of sound varies inversely as the wavelength.
So, we can set up an equation as following:
f*w = k Where k= constant of variation.
Other information is, the frequency of a musical note is 276 cycles per second when the wavelength is 1.2m.
So, next step is to plug in f = 276 and w = 1.2 in the above equation to get the value of k.
276 * 1.2 = k
So, k = 331.2
Next step is to plug in k = 331.2 in the above equation. So,
f * w = 331.2
Now we need to find the wave length : w when frequency : f = 600.
Therefore,
600 * w = 331.2

So, w = 0.552
Hence, the wave length is 0.552 m.
Hope this helps you!.
