Answer 3

Ek...embryo's got this.

Answer 4

1. = C.

Answer 5

Don't just give the answers. .-. EXPLAIN HOW YOU GOT THEM

Answer 6

B.
9! / [4!(9-4)!] = 126
More detailed would be to expand the factorial and cancel out terms like 9x8x7x6x5x4x3x2x1/[4x3x2x1(5x4x3x2x1)]

Answer 7

ist the first 4 numbers starting from 10

10 9 8 7

then multiply them together

10*9*8*7 = 10p4

Answer 8

Ohhh, Permutation and Combination, alright, so recall what the formulas for those are, Permutation is as follows\[aPb=\frac{ a! }{ (b-a)! }\]where "a" and "b" are both numbers that you are given, Combination is as follows,\[aCb=\frac{ a! }{ b!(b-a)! }\]where again, "a" and "b" are both numbers that you are most likely given, now if you don't remember what "!" means in math, it's just the multiplication of that number times one less of itself until you get to 1, so\[5!=5*4*3*2*1\]

Answer 9

Yep

Answer 10

Sorry, i'm pretty slow at typing out my explanations, always making sure i did it right, making sure i don't overlook anything.
