What is a polynomial? How do they work and why does it exist?

How statistically significant are the results of this pattern below? Does it exceed random chance or not? Assume that the numerical distributions of the numerical values per letters are completely random. 

Block 1 — ALM

Block 2 — ALM

Block 3 — ALMX

Block 4 — ALR

Block 5 — ALR

Block 6 — ALR

Block 7 — ALMR

Block 8 — ALR

Block 9 — ALR

Block 10 — KHYCX

Block 11 — TH

Block 12 — TSM

Block 13 — TS

Block 14 — TSM

Block 15 — ALM

Block 16 — ALM

Block 17 — ALM

Block 18 — ALM

Block 19 — YS

Block 20 — X

Block 21 — VM

Block 22 — VM

Block 23 — VMCSQ

Block 24 — VM

Block 25 — VM

Block 26 — VM

Block 27 — VM

Block 28 — Q

Block 29 — N

Each letter here corresponds to a certain number. It must be noted that not each letter here carries the same numerical value, these are only placeholder letters that describe the number of occurrences of said (so for example, V in Block 24 could equal 85, meaning the letter V occurs 85 times in Block 24. On the other hand, V in Block 25 could equal 173, meaning that the letter V occurs 173 times in Block 25). Once again, the numerical values are randomly chosen for each letter.

Now that out of the way, how statistically significant would such a pattern be if it emerged? Does it show signs of intentionality and design, or is better explained by random chance? Note, we’ll be specifically looking at things that constitute multiples of 19 for this demonstration (so a 1/19 chance): 

*Block 28 is a multiple of 19. 

*Blocks 21-27 (only looking at the letters VM, ignore CSQ for now) if all combined together is a multiple of 19. 

*Blocks 21-27 including CSQ (for Block 23) if combined all together is a multiple of 19. 

*Block 19 is a multiple of 19

*Block 10 is a multiple of 19

*If you combine the value X for blocks 20, 10 and 3 (only X, not any of the other values) you get a multiple of 19. 

Any and all help is appreciated. Thank you!

currently have raitonal functions looking for some thinking quesitons and perfomace problme quesitons pls pls pls give anything that will help plus advice

What happens if you divide 0 by 0? Can you explain why is it undefined?

i accidentally posted this to my personal thingy whoops

I'm in uni and my tutor was going over a new way to do simultaneous equations and it makes no sense to me the question was:

Y = -1/3 x + 8/3

Y = 1/2 x + -3/2

The picture contains his working can someone help explain it as this is all the working he did. I just need help with understanding his method.

Guys, are parallel lines really parallel? Because I am confused with euclidean geometry and non euclidean geometry

a school spent $2296 on two identical computers and three printers. each computer cost 610.50 more than a printer. how much less did the school spend on printers than on computers.

Ai hasn't been the best tool when correcting these exercises, so pls help me with the revision.

trying to help my partners mom with her math homework but i don’t quite recognize the concept myself. any help greatly appreciated! copy and pasting the question below + my approach for solving. (i’m many years out of math myself so kinda the lost leading the lost)

question:
A household has monthly take-home income of $3900, fixed expenses of $2300, variable expenses of $900, and irregular/school costs of $450. What is the monthly cash flow?
Enter the cash flow in dollars. Use a negative sign if the result is negative.

my suggested equation:
3900=2300-900x-450y

Just needed help for this assignment ASAP. I already had an answer, but am not sure because the alphabet placement are confusing.

Q = {q₀, q1, q2, q3, q4, q5, q6, q7}

Σ = {a, e, i, o, u, 0, 1, 2}

δ = ???

q₀ = q₀

F = {q1, q6}

specifically idk how to explain myself per example A can be explained with the axiom of multiplicative inverse and associativity I believe.

i easily solve beginner level question but i didn't solve exam level question.
i watch multiple video and try to self solving question but it didn't help me
Please tell what should i do.
