lesson+16+to+22

lesson16: List combinations, permutations, and write your observations on the similarities and differences. the differences an simularities all basically change or have a different outcome depending on what numbers you decide to generate or enter in for N,K i entered 7,2 for N,K(1,3)(2,3)(1,4)(2,4)(3,4)(1,5)(2,5)(3,5)(4,5)(1,6)(2,6)(3,6)(4,6)(5,6)(1,7)(2,7)(3,7)(4,7)(5,7)(6,7)

lesson18: the permutation practice activity game thing i didnt like it at all i dont know if because im not in the mood for math today or it just is overly complicated to look at with the different number combinations an such. But this is class all together is going quite well im just finishing up my problem sets an will shortly be posted i missed a few days due to my mother being in the hospitol.

lesson19: the combination practice activity game was a slight bit easyer then the permutation but still complicated and complex with all the different numbers and the formula like n=stands for total number of items and r= stands for how many things your choosing. like ( nCr= n!/r!(n-r)! For 0<R<N ) but im sure within time i will understand more of this whole concept.

lesson20:Write about social engineering security threats.

social=used among hackers for cracking techniques that rely on weaknesses in physical security rather than software to trick people into revealing passwords or other information that compromises a target system's security. Classic scams phoning up an employee who has the required information password, username, and being a poser trying to look like a comp tech or someone you work with. they can be female or male they act like they know the make and model so its not so obvious they are after serial numbers they go the extra mile to get extra info and they usually contact you blocked.

lesson22: anwser ?s about linear regression activity.

alot of different lines through one point in the plane computers are dumb and dont know which one to do errors in the subject problem differ because of putting the point in the wrong place and they take up mos def alot of room on the graph/plane one line that goes through 3 of the points kinda like a ray when they arent in the right place they move to or connect to the new point an the ones far away will move further a real life sit. could be like whats the healthy size or weight of your dog or yourself you could use the plot the computer computes the graph beacause your telling you too like i said computers are to a sence stupid they do what ever you say and say you put in the wrong data it doesnt matter because the computer will only know what to do by what you tell it to do.
