What animals fangs are less then a finger width apart and lives in Alberta?

It's hard to answer this without more information, but a 'finger width apart' is pretty narrow, so assuming you have bite marks on something or a skull, I'm guessing a raccoon, skunk, or weasel - something with pretty well developed fangs (a carnivore) and small. What do you have to provide more information, color of the animal, size ...

How is the mean found for a set of data?

The mean of a set of data is the average. You find it by adding the numbers and dividing by the amount of numbers. For example

1, 2, 3, 4, 5, 6, 7

mean = 1+2+3+4+5+6+7 / 7

28/7 (28 is the sum of the numbers, 7 is the amount of numbers in the set)

The mean is 4.

How many numbers can be made using a 7 a 5 and a 3?

We need to know how many digits the number is and if we can allow repeats. I will do this problem assuming 3 digit numbers and allowing repeats. Then there are 3 choices for each digits and 3x3x3=27 words of length 3. If we want to consider words of length 2 also, add 9 and of length 1 add 3 and for 0, we use none of them. So there are missing details we need to be sure we are doing the problem correctly. It all depends on exactly what is being asked!

What is the value of a 1996 uncirculated 100 bill with misalignment print error on front?

Alignment errors on U.S. currency vary significantly in value. If the image is still all within the borders of the paper it's considered a minor error and is generally worth very little above face value if anything. However, if the printing is far enough off that part of the image of another bill is visible, it's much rarer and could sell for $200 to $600 depending on the extent of misalignment. You would have to take the bill to a couple of dealers who specialize in error currency to get competing estimates.

Is there a way to form an equation equaling 1 using all ten digits at once?

Sure, there are many. A couple of simple examples would be:

x = (9 - 8) * (7 - 6) * (5 - 4) * (3 - 2) * (1 - 0)
x = 9 - 8 - 7 + 6 + 5 - 4 - 3 + 2 + 1 - 0

You're not limited with that though. Consider: any value other than zero, when raised to the power of zero, is equal to 1. This means that you can take any combination of the other numbers, and as long as they are not equal to 0, then you can raise them to the power of zero to get an end result of 1. For example this equation:

x = [√7 * 2 / 65 + 8 - ∫13(4x9)dx]0

is just as valid as the ones given above.
