Answer:
It's -32x^2
Step-by-step explanation:
Answer:
And we can find this probability with this difference:
If we use the normal standard table or excel we got:
And that represent 95% of the data. so then the percentage below 2450 is 2.5% and above 4390 is 2.5 %
Step-by-step explanation:
Let X the random variable that represent the birth weights of a population, and for this case we know the distribution for X is given by:
Where 
and 
We are interested on this probability
And we can use the z score formula given byÑ
If we apply this formula to our probability we got this:
And we can find this probability with this difference:
If we use the normal standard table or excel we got:
And that represent 95% of the data. so then the percentage below 2450 is 2.5% and above 4390 is 2.5 %
Answer:
680 games
Step-by-step explanation:
Suppose that 681 tennis players want to play an elimination tournament.
1st round:
One of 681 players, chosen at random, sits out that round and 680 players play. There will be 340 winners plus one player which sits - 341 players for the next round and 340 games
2nd round:
There will be 170 winners plus one player which sits - 171 players for the next round and 170 games
3rd round:
There will be 85 winners plus one player which sits - 86 players for the next round and 85 games
4th round:
There will be 43 winners - 43 players for the next round and 43 games
5th round:
There will be 21 winners plus one player which sits - 22 players for the next round and 21 games
6th round:
There will be 11 winners - 11 players for the next round and 11 games
7th round:
There will be 5 winners plus one player which sits - 6 players for the next round and 5 games
8th round:
There will be 3 winners - 3 players for the next round and 3 games
9th round:
There will be 1 winner plus one player which sits - 2 players for the next round and 1 game
10th round - final:
1 champion and 1 game.
In total,
340 + 170 + 85 + 43 + 21 + 11 + 5 + 3 + 1 + 1 = 680 games
