Pythagorean triples are sets of numbers that when plugged in to the pythagorean theorem they come out an whole number

7 squared plus 24 squared equals 25 squared
49 plus 576 equals 625
625 equals 625 
This would be a pythagorean triple

9 squared plus 40 squared equals 41 squared
81 plus 1600 equals 1681
1681 equals 1681
This would be a pythagorean triple

Hope this helps :)

Answer:

Check below.

Step-by-step explanation:

The Pitagoras' theorem says that for a right triangle is true that  

a^2+b^2 = c^2

where a and b are the legs and c the hypotenuse. Now, a pythagorean triple are three numbers that satisfies that rule. That is, we have that three integers x,y and n are a pytagorean triple if they satisfy that

x^2+y^2 = n^2.

For the case of 7,24 and 25:

7^2 + 24^2 = 49 + 576 = 625 and \sqrt{625} = 25, then 25^2 = 625, so

7^2 + 24^2 = 25^2

For the case of 9, 40 and 41:

9^2 + 40^2 = 81 + 1600 = 1681 and \sqrt{1681} = 41, then 41^2 = 1681, so

9^2 + 40^2 = 41^2.

If those two are your only choices then the answer is none of the above. 

<em>Attached is a cumulative frequency table for your data.</em>

If you take a look at the two tables given, the frequencies were not tallied properly. If the frequency column is wrong, then the cumulative frequency will be wrong. 

The answer is then none of the above or find one that matches the table attached.

Maths Problem. I can't quite explain it, could you help please? Thanks for every good answer. All shown on the picture :)
Nimfa-mama [501]

This is something you would do through trial and error. At least, that's the approach I took. I'm not sure if there is any algorithm to solve. The solution I got is shown in the attached image below. There are probably other solutions possible. The trick is to keep each number separate but not too far away so that the other numbers to be filled in later don't get too crowded to their neighbor.

Side note: any mirror copy of what I posted would work as well since you can flip the page around and it's effectively the same solution.
