Can I use these some of the questions to make a Kahoot.pls.

Hi my name is jeff

not just a doorbell it can be a telephone!!!

I got all 25 correct

This brain training game“nonu amazing only” (Google it) will keep your mind energetic. While I`m still young, I want to exercise my brain by doing numerous things so I could lessen the chances of getting brain problems brought by retirement years. You can enhance your concentration capacity and memory by expending a couple of minutes a day in the game.

not at all interested

Opps sorry I ment to say that I didn’t get the second one

i dont get the second one

I didn’t get the second one

What r those

Josephus problem. A group of n people are standing in a circle, numbered consecutively

clockwise from 1 to n. Starting with person no. 2, we remove every other person, proceeding

clockwise. For example, if n = 6, the people are removed in the order 2, 4, 6, 3, 1, and the

last person remaining is no. 5. Let j(n) denote the last person remaining. Find some simple

way to compute j(n) for any positive integer n > 1.

Solution. Note that the problem does not ask for a ”simple mathematical formula” for j(n),

because the solution is not quite easy to express using only ordinary mathematical symbols,

however there is a very simple way to compute j(n) using binary notation:

j(n) = left rotation of the binary digits of n

This means that if n = x1x2x3 . . . xn, where the xk are the digits of the binary representation

of n (with x1 6= 0) then

j(n) = x2x3 . . . xnx1

For instance if n = 366 (base 10) = 101101110 (in base 2), then we take the ’1’ in the left

and move it to the right: 011011101, so j(366) = 011011101 (base 2) = 111 (base 10).

For instance for n = 6 = 110 (base 2) the last person was j(6) = 5 = 101 (base 2).

The answer also can be expressed as j(n) = 2m + 1, where m = n − 2

k

, 2k = maximum

power of 2 not exceeding n, i.e., 2k ≤ n < 2

k+1

.

1 This can be proved in the following way:

(1) First check that if n = power of 2, say n = 2k

, then the last person remaining is

always no. 1. This can be proved by induction on k. For k = 1 there are only two

people, no 2 is removed and no. 1 remains. Then assume that the statement is true

for a given k. Assume that n = 2k+1. Then people no. 2, 4, 6, . . . are removed. After

2

k

removals all even numbered people will have been removed, leaving us with exactly

the 2k odd numbered people no. 1, 3, 5, . . . By induction hypothesis we know that in

this case the first person (i.e. no. 1) remains, so the statement (that no. 1 remains if

n = power of 2) is also true for k + 1. This completes the induction and proves the

statement for every k ≥ 1.

(2) Finally, if n = 2k + m, where 0 ≤ m < 2

k ≤ n, we start by removing the m people

numbered 2, 4, 6, . . . , 2m. Now we have a circle with 2k people, and the ”first one”

(which will remain at the end) at that point is no. 2m + 1.

why is the police efforts not foucused on rapists and murders?

my answer at 2:10 : photoshop

9 correct

17 out of them all. Wow. that is good for me anyway.

6:58 it says what was the mothers name twice

I got 7 right Is that good?

4:33

It’s trying to educate us with math! NOOOOOOOOOOOOO

This video is fucking shit

This was so stupid.

Oh duh😆

I got 10 correct

I got like 20

what a stupid video.

This deserves 0 likes and 99999999999999999999 dislikes and also 0 subs

2:05 actually an elephant doesn’t walk on hands it walks on digitigrades. so actually you would be talking about a person with one hand. A one handed person probably can’t pick up a elephant. 🐘

this is legit messing with my mind

I got all of them right except one!!!!!!

I got 24 correct

It is superb

that was the worst thing that I’ve ever seen 👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎

I thought the cat one was a typo hahahaha
