1) Calculate mean yearly temperature using the data in the chart below. Give the answer to two decimal places.
2) Give the mean monthly temperature of July using the chart .
Answer:
(a) Mean yearly temperature = 10.58
(b) [tex]July = 24^\circ C[/tex]
Explanation:
Given:
The attached chart
Solving (a): The mean yearly temperature.
This is calculated as:
[tex]\bar x = \frac{\sum x}{n}[/tex]
[tex]\bar x = \frac{-5 + 2 + 6 + 10+15 + 22+24+21+17+12+6-3}{12}[/tex]
[tex]\bar x = \frac{127}{12}[/tex]
[tex]\bar x = 10.58[/tex]
Solving (b): The mean July temperature.
From the chart:
[tex]July = 24^\circ C[/tex]

Which city on the map probably has about the same type of weather year round?
Answer:
I think F but im not too sure.
The city on the map probably has about the same type of weather year round is the F city.
What is the weather?Weather is defined an atmosphere of a particular state. It shows the temperature in degree and also predict the upcoming season in a particular locality.
It is scientifically proved that the weather at the top most of a particular map changes for some time.
but it is clearly denotes that the lowest part of the map is hotter than the other parts and remains same in all time.
The lower part of the map is generally hot at every time because there is huge difference between the upper parts of the map.
Example: the Himalayas is normally a cold climate because it is an icey area, then going to down, the temperature of climate gets hot ultimately.
Therefore, F area is hotter than the other areas and this is about the same type of weather in all the season.

Describe how scientists can use vibrations during earthquakes to figure out if the Earth is made up of liquid or solid deep inside?
&
Describe how you can use earthquake vibrations to prove the inside of the Earth is made of separate layers
Answer:
Scientists use waves to study the different layers of the earth. Usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test explosions. The seismic waves are bent, sped up, or slowed down, or even reflected when they pass through the earth's layers.
Seismic waves are recorded by a machine called a seismograph, which tells us about the strength and speed of the seismic waves. Seismic waves travel at different speeds when they pass through different types of material, so by studying seismograms, scientists can learn a lot about Earth's internal structure.
Explanation:
Does this help??
Answer:
Seismic waves
Explanation:
Seismic waves provides evidence for the internal structure of the Earth, which cannot be observed directly. Seismic waves from large earthquakes are detected around the world. Their paths are curved as the waves refract due to the gradually changing density of the layers.
Hope this helps :)
