Of the $10$ kids in a chess club, $5$ are left-handed and $5$ are right-handed. the club holds a round-robin tournament in which every player plays against every other player exactly once. what fraction of the games have two right-handed players? enter your answer as a fraction in simplified form.
The total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 is the fraction of all games at the tournament Anita plays.
How to carry out Permutation and Combination?
We are given that there are 5 girls and 5 boys in a chess club.
Thus, total games that girls play against a boy = 5×5 = 25
The number of games a girl play against another is the total number of games = 10
The number of games that are boy vs boy = 10
The number of games Boy vs Boy + Girl vs Girl + Boy vs Girl = 10 + 10 + 25 = 45
Fraction of the games that are boy vs boy = 10/45 = 2/9
If Anita is one of the club members, then Anita will have to play against 9 people at the tournament.
Total number of games = 45
Then the fraction of all games at the tournament Anita play the game.= 9/45 ⇒ 1/5
Thus, the total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 fraction of all games at the tournament Anita plays.

From previous experience, the owner of an apple orchard knows that the mean weight of gala apples is 140 grams. there has been more precipitation than usual this year. the owner believes the weights of the apples will be heavier than usual and therefore the crop will be more profitable. this will allow the owner to expand the orchard. the owner takes a random sample of 30 apples and records their mean weight. what is the consequence of a type i error in this situation?
The consequence of a type I error in this situation is that the owner believes the crop will be more profitable and expands the apple orchard.
What is a type I error?
A type I error can be defined as a type of error that occurs when the null hypothesis is rejected, even though it's actually true.
This ultimately implies that, a type I error concludes that a given result is statistically significant, whereas, in reality, it was due to luck, chance or other unrelated factors.
In this scenario, the consequence of a type I error in this situation is that the owner believes the crop will be more profitable and expands the apple orchard, when the true mean weight of the apples is actually lesser than 140 grams.

Answer:
33 minutes
Explanation:
So, Copper went into the store at 4:40 p.m. then came out at 5:13 p.m.
One way to visualize this is to first count the minutes to 5:00 p.m. and then add the minutes after that. So, there is 20 minutes till 5:00 p.m., and then 13 minutes until 5:13 p.m. 20 + 13 = 33 minutes. This makes it easier to see how long Copper took in the store.

The best estimate of the value of the account 12 years after it was opened is; B: $8,980
How to solve exponential regression Model?
The exponential regression model can be written as exponential function in the form; y = abˣ
From the attached table, after 0 years, the account value is $5000. Thus;
5000 = a * b⁰
a = $5000
After two years, we have;
5510 = a * b²
5510 = 5000 * b²
b² = 5510/5000
b = √ 5510/5000
b = 1.05

Lisa has collected data to find that the number of pages per book on a book shelf has a normal distribution. what is the probability that a randomly selected book has fewer than 141 pages if the mean is 193 pages and the standard deviation is 26 pages? use the empirical rule. enter your answer as a percent rounded to two decimal places if necessary.
Rounding to two decimal places, the probability that a randomly chosen book contains fewer than 141 pages is about 2.5%.
What amount of money has Lisa amassed in the past six months that is 15% greater than 1,250?If you tell us that you have saved 15% of your income plus $1,250, we must first divide that amount by 15% to arrive at 187.5, and then we must add that figure to $1,250 to arrive at 1,437, which is Lisa's money.
In this issue, our goal is to determine the likelihood that a randomly chosen book contains fewer than 141 pages.
Where x is the value we're interested in (141 pages), is the mean (193 pages), and is the standard deviation, we get the equation z = (x - ) /. z = (141 - 193) / 26 = -2
The z-score informs us of how many standard deviations our value deviates from the mean. 141 pages in this case are two standard deviations away from the mean.
We may estimate that 95% of the data falls within two standard deviations of the mean using the empirical method. We can estimate that P(X 141) 2.5% is the likelihood of choosing a book with fewer than 141 pages.
