P (blue/blue) = 7/9 x 4/9 = 28/81
P (pink/pink) = 2/9 x 5/9 = 10/81
28/81 + 10/81 = 38/81
P (Same colour) = 38/81
Answer:
9.44 inches
Step-by-step explanation:
In order to find the average rainfall, setting up a proportion, or equivalent ratios, would be the easiest way to find the measurement. Given that 23.6 inches represents 250% of the average:
, where 'x' represents the average rainfall
cross-multiply: 250x = (23.6)(100) or 250x = 2360
divide: 250x/250 = 2360/250
x = 9.44 inches
Answer:
1012
Step-by-step explanation:
Given:
pitch 'p' = 460 vibrations per second
wavelength 'w'= 2.2m
'k' represent constant of variation
'k' can be determined by taking the product of pitch and wavelength
k= p.w
k= 460 x 2.2
k= 1012
Therefore,
the constant of variation is 1012
Trigonometry functions is often employed in taking the measurement of the level or the pitch of a sound wave or musical note.
The change of amplitude of a sound wave's amplitude is linked to the change in pressure that occurs due to the wave measured at a given location.
Frequency tells the number of waves that pass a fixed location in a specific time frame.
<h3>How does sound waves relate to trigonometric functions?</h3>
Sound engineers uses the basic laws of trigonometry via sine and cosine graphs.
Note that all sounds can be broken down into a lot of sine waves, as sine waves comes together to form sounds.
Therefore, Trigonometry functions is often employed in taking the measurement of the level or the pitch of a sound wave or musical note.
