Mean is the same thing as average, so to find this you would add all of the numbers together and divide them by the amount of numbers you added. For example, (6+9+11)/3
Median is the middle number of the list of numbers, but you have to put them in numerical order first. If there is not an exact middle, you would add the middle two together and divide by two.
Mode is the number that occurs most often within the list of numbers.
Answer:
its because the stae are far west too
point y is in the interior of xwz. given that and are opposite rays and mxwy4(mywz), mywz = 36°
Opposite rays:- Opposite rays are the rays, which shares a common initial point, but points towards opposite directions. Angle between two opposite rays is 180°.
According to the question,
m∠XWY = 4(m∠YWZ) (Given)
As the two rays WX and WZ are opposite rays, the initial points of those are same. Here in the question, it is W.
∴∠XWZ = 180°
∴m∠XWY + m∠YWZ = 180°
⇒ 4(m∠YWZ) + m∠YWZ = 180°
⇒ 5(m∠YWZ) = 180°
⇒ m∠YWZ = 180°/5
⇒ m∠YWZ = 36°
Thus we can conclude that, m∠YWZ = 36°.

Answer:

Explanation:
Let's start finding the frequency heard by the bystander due to the moving car. We need to use Doppler effect here:
v is the speed of sound (v = 343 m/s)
So, we have:
Now, the beat frequency heard by the bystander is the combine of the frequencies, it means the difference between them. Therefore the equation is given by:
