12 x 12 = 144

21 x 21 = 441

29 x 29 = 841

As you may have noticed, all these 3 digit square numbers have a 4 as the second digit.

Hope this helped

odd numbers, perfect square numbers

In any given set, the arithmetic mean is the average, which is the sum total of the numbers divided by how many numbers there are.

Ex. (10, 17, 20, 45, 68)

68 + 45 + 20 + 17 + 10 = 160

There are 5 numbers in this set.

160/5 = 32

The mean is 32.

The explanation uses the variable "n" because it doesn't know how many numbers are in the set.

English words put together in a nonsensical pattern is what it is.

You are making an estimate.

You are making an assumption that the model is appropriate and that it is valid for the required values of the independent variables.

> Add 5 and 6 together and - 1

The previous answer give 10, not 9. Here's another way:

Using bar notation to denote an infinitely repeating decimal, 0.6666666... can be represented as .6 with a line drawn over the 6. The best I can do here is to put a line through the 6: .6 = 0.6666666..... If you were writing this by hand, you would put the line over the 6, not through it.

Then (5+1)/.6 = 9

prime factorization each number is a part of the whole

18:20 reduces to 9:10 if you divide both sides by 2

There's a lot of possible answers to this one. Is it that each digit can be 0 through 9? In which case you get every number from 0000 to 9999 which is 10,000 possible answers. Or is it that each number can only be used once? In which case, the first possible answer is 0123 and the last possible answer is 9876. That still leaves 5,040 possible answers, which is way too many to just list. Here's the first 15 though to get you started.

0123 0124 0125 0126 0127 0128 0129 0132 0134 0135 0136 0137 0138 0139 0142

Yes.

Because the theory of coin flipping is well understood and so theoretical probabilities can be used.

For discrete data, a bar chart. For continuous data a grouped frequency chart (histogram).

Texting a hypothesis is no different to texting a message! So a piece of word processing software, or even a SMS on a phone will suffice.

Assuming you can use each digit only once, the logical answer has to be 9,876,543,210 (since you would want to use the largest numbers in the highest value places).

Use a protractor or a compass

Mode is the most frequent occurring number; for this set is 66.

Devora or Dvora (דבורה) is a Hebrew name that means "honey bee"

Class frequency

You might use the general FFT method in system identification:

At least you can start with this:

1. Calculate the FFT of your output (the step response plot)
2. You know what the FFT of your input (the heaviside function) is: 1/2*pi*f
3. devide the first by the second and end up eith the calculated transfer function.
4. Plot the Bode plot (magnitude and phase / frequency)
5. Fit it with a transfer function that you know and has second order characteristics. A system with two poles with or without a zero. stuff like that

Good luck!

Yes. If you are conducting a study, and collecting data, the number of cars would be a discrete variable.

There are numerous different types of mean, some a lot more used than others. thhe main ones are:

* Arithmetic mean * Geometric mean * Harmonic mean

How about NJ.or BJ.
