The answer is 34 you have to add the numbers and divide them by how many numbers there are

Alright so to find the mean we have to add all the numbers (data) together and then divide it by the amount of data. So two people are 30,two at 32, one at 34 and three at 36

so our problem is....
30+30+32+32+34+36+36+36= 266

Now we do 266/the number of data used, which is 8
so
266/8=33.25

Hope that helped ;)

If you dont understand something i did ask and i can re explain

Answer all questions in this part. Directions (51 - 65): Record your answers in the spaces provided in your answer booklet. Some questions may require the use of the 2011 Edition Reference Tables for Physical Setting/Earth Science. Base your answers to questions 51 and 52 on the diagram and data table below, and on your knowledge of Earth science. The diagram represents the laboratory materials used for an investigation of the effects of particle size on water retention. Five separate columns were filled to the same level with particles. The particle type is indicated for each column. The particles within each column are of uniform shape. A volume of 50 milliliters (mL) of water was poured through each column, and the amount of water retained was determined. The data table shows the results of this experiment.

A halfback on an apparent breakaway for a touchdown is tackled from behind. If the halfback has a mass of 98 kg and was moving a

uranmaximum [27]

Answer:

The mutual speed immediately after the touchdown-saving tackle is 4.80 m/s

Explanation:

Given that,

Mass of halfback = 98 kg

Speed of halfback= 4.2 m/s

Mass of corner back = 85 kg

Speed of corner back = 5.5 m/s

We need to calculate their mutual speed immediately after the touchdown-saving tackle

Using conservation of momentum

$m_{h}v_{h}+m_{c}v_{c}=m_{h+c}v_{h+c}$

Where, $m_{h}$ = mass of halfback

$m_{c}$ =mass of corner back

$v_{h}$ = velocity of halfback

$v_{c}$ = velocity of corner back

Put the value into the formula

$98\times4.2+85\times5.5=(98+85)\times v$

$v=\dfrac{98\times4.2+85\times5.5}{98+85}$

$v=4.80\ m/s$

Hence, The mutual speed immediately after the touchdown-saving tackle is 4.80 m/s

In the real world, the pendulum in a clock eventually comes to a stop. Someone or something needs to supply energy for the clock

Leno4ka [110]

Answer:

USING LAW OF CONSERVATION OF ENERGY

Explanation:

As we know that energy can not be created nor be destroyed.The pendulum cannot continue moving on its own because it meets energy losses due to friction.Its energy is converted into heat energy which dissipates in the air

Hey there!

Answer: Glaciers

Water near the poles would most likely be stored as glaciers. Glaciers are slow moving rivers that are a buildup of ice and snow.

What are the functions of proteins in organisms?

lana [24]

Good morning.
The only reason I answered this is because this question was looking lonely. Like, /desperate lonely/. Anywho, let's work.

Proteins are biomolecules that have multiple jobs to do in an organism. Examples of their functions are below.

1. They are used to transport molecules.
2. They are used to place/store molecules.
3. They are needed for movement of the cell.
