3 is wrong. It is 105,000
4) 13/60=0.21666 0.21666*360=78 so 78 degrees
5)sequential difference is 7 and the first term is 4 so 7n-3
6)4x-4=2x-10,2x=-6,x=-3
7)5(4)(5)+4^2=100+16=116
8)(-3,7)
11)a=180-70=110 b=a=110 c=70
12)Sum or angles of a hexagon=(6-2)(180)=720. 720/6=120
13)3/51 because there are only 3 aces in the deck and 51 cards in total
You did 14 wrong. It should be 9/12*144=108
17)First and third. Plug in 0 for x
18)72/9*2=16 72/9*7=56 so 16:56
19)2*3+2*3/2=9

Is 4-heap Nim with heaps of sizes 22, 19, 14, and 11 balanced or unbalanced? Player I's first move is to remove 6 coins from the
nadya68 [22]

Answer:

Player II should remove 14 coins from the heap of size 22.

Step-by-step explanation:

To properly answer this this question, we need to understand the principle and what it is exactly is being asked.

This question revolves round a game of Nim

What is a game of Nim: This is a strategic mathematical game whereby,  two opposing sides or opponent take turns taking away objects from a load or piles. On each turn, a player remove at least an object and may remove any number of objects provided they all come from the same heap/pile.

Now, referring back to the question, we should first understand that:

                        22₂ = 1 0 1 1 0

                         19₂= 1 0 0 1 1

                         14₂= 0 1 1 1 0

                          11₂= 0 1 0 1 1

and also that the “bit sums” are all even, so this is a balanced game.

However, after Player I removes 6 coins from the heap of size 19, Player II should remove 14 coins from the heap of size 22.
