So the first step is to find what is 1+2+3+4+...+199+200 you can do that by having pairs of 201 so there are 100 pairs and 201x100=20100 and so there are 20100 numbers in the list.

The second step is to find the sum

and the third step is to divide the sum by the umbers. Use these hints!

As ever,

Given is a quadratic xpression which is greater than equal to 0, thus, D = b^2-4ac <0
(2(4k-1))^2 - 4(15k^2-2k-7)<0
k^2-6k+8<0
(k-2)(k-4)<0
Thus, 2 or, k=3

P (Heads  ≥ 8 flips)  =  P( Tails ≤ 2 flips )  =

C(10,0)(1/2)^10   + C(10,1) (1/2)^10  + C(10,2)(1/2)^10  =  7 / 128

Answer:

At the end of the 10 th week

Step-by-step explanation:

My team plays 3 games and lost all of them  (12 $ ) in the first 4 week 

so in 4 weeks my team lost  12 $ and all the games  

Then total games in three weeks is   4 * 3  = 12

Total lost  12$  then we have a one dolar bet

In the 5th week my team wins 2$ ( two games ) and at the end of 5th week record is:

From 15 games  my team won  2  games  and lost  13 games and from that on, my team always wins 2 games then:

Let call x number of week after the 5th then

2 + 2*x / 15 + x  =  0,6                                0,6  =  60 %

Solving for  x

2 + 2*x  =  0,6 * ( 15 + x )

2 + 2*x  =  9  + 0,6 *x

2*x - 0,6*x  =  9 - 2

2*x - 0,6*x  = 7

1,4*x  = 7

x  =  7/1,4

x  =  5 weks later

Then the answer is 10 weeks

Techno the p*g,

No problem

Thank you so much for taking time out of your day to help me with this, but that was not the right answer

I hope this is helpful🙃

I believe you can set up a proportion for this. So:
d/c = d/c or 8/9 = x/6
*cross multiply*
9x = 48
*divide both sides by 9 to get x by itself*
x = 5 1/3 

Thank you 😊.

\(Z= -5/2 -I(5\sqrt{3}/2\)
 

Im pretty shure this is the right answer.
