A pace chart tracks your time and distance for various types of runs. You create one by setting up what you want to track and letting Excel do the arithmetic for you. It can be used by marathon runners to evalute their performance and determine what specifc aspects of their running needs work.

See related links for examples of pace charts.

This is a very broad question. I have included a link from the Internet, but you can find many other links by searching under sampling methods.

Usually the question is:

What makes a sample's statistics be an accurate representation of the population?

No sample is a perfect representation of the population, but some samples are more representative than others.

If you are conducting a survey, you should make sure that the results are unbiased. For example, if you are asking people if they like to excersize, you should not do this at your local health club and then claim your sample represents everyone in your community.

Your sample should contain enough data. Sometimes, important surveys require hundreds or thousands of interviews. Asking a few people questions is not a good way to collect a sample.

There should be a plan to your collection of data, that is well documented. Sometimes, it is necessary to have a professional outside group conduct the study, so a representative sample is gathered. The Gallup organization are very well known for conducting political surveys. You don't want someone to "pick and choose" his data to get a certain result.

These are just some ideas- you may find more in the related link.

5!
----- x 8 x 8 x 8 x 26 x 26 (I think - I haven't done this at college yet but this
3!2! seems logical. Someone will have to corroborate me)

Which is 10 x 8 x 8 x 8 x 26 x 26 5120 x 676... I wish I had a calculator... please don't take my word for this lol. 3,380,000 + 67,600 + 13,520 = 3,461,120

I need more information. I would guess a deck of 32 cards would only have 8 card in each suit, so it would be impossible to draw 12 cards of the same suit.

There are 499 of them and I do not have the time nor inclination to list them. Start at 501, and keep adding 1 until you get to 999. Then stop.

There are 36 permutations of rolling two dice. Three of them, (4,6), (5,5), and (6,4) add up to ten. Therefore, the probability of rolling ten on two dice is 3 in 36, or 1 in 12, or about 0.0833.

If you use a normal card set, it would be 8/53 chance, because it it 4 queens an 4 Jacks (8 in total) and 52 cards to pick between. If you reduce it, the probability would be 2/13.

52 right

0 - none

A graph that leads you to think something else

There are 10 centimetres in one decimetre. Therefore, 100 centimetres is equal to 100/10 = 10 decimetres.

no edges but 3 faces.

A score is an old-fashioned word representing 20.

If each number is different from all of the other numbers and the combinations are considered distinct unless they contain the same numbers in the same order, the answer is 25 X 24 X 23 X 22 X 21 = 6,375,600. If the combinations are distinct only if they do not contain the same numbers, irrespective of order, then the answer is (25 X 24 X 23 X 22 X 21)(5 x 4 x 3 x 2) = 53,130.

One of the fundamental requirements of any scientific theory is that experiments are replicable. This requires reuslts to be comparable which would be impossible if members of the community did not use the same units.

They use display screens and optical systems that send 3D images to the eyes. Motion sensors in it measure the position and orientation of the head; this information is sent back to a computer which enables it to adjust the image sent back to a user.

Yes. They could increase the width and thereby reduce the frequency densities (heights) of the one or both of the outermost classes.
