(the half-life of carbon-14 is 5730 years.)
The wooden artifact was made approximately 3,183 years ago. The amount of carbon-14 present in an artifact can be used to determine how long ago the organism that the artifact came from died.
The half-life of carbon-14 is 5730 years, which means that every 5730 years, half of the carbon-14 in a sample will decay. Let's call the amount of carbon-14 in the living tree sample 100%. Since the artifact contains 35% of that amount, we can write:
0.35 x 100% = 100% x (1/2)^(t/5730)
where t is the number of years since the artifact was made.
Simplifying this equation, we get the following:
0.35 = 0.5^(t/5730)
Taking the logarithm of both sides, we get:
log(0.35) = (t/5730) x log(0.5)
Solving for t, we get:
t = (5730 x log(0.35)) / log(0.5)
Using a calculator, we get:
t ≈ 3,183 years
Therefore, the wooden artifact was made approximately 3,183 years ago.

At the balloon dart booth, players are charged $1 for the chance to throw 3 darts, Prizes worth $4 each are awarded to players who pop at least 2 balloons. Last year, 4 out of 12 players popped 2 balloons, and 1 out of 12 players popped 3 balloons.
If the ratio of winners to players remains the same as last year, the balloon dart booth can expect to have 85 winners among 204 players and lose $136.
A ratio compares two quantities or values. In this case, the ratio we are interested in is the ratio of winners to players.
Last year, out of 12 players, 4 popped 2 balloons and 1 player popped 3 balloons. Therefore, the total number of players who won prizes was 4+1=5. The ratio of winners to players is 5/12.
To calculate the number of winners this year, we can use the same ratio. If we assume that the ratio of winners to players is constant, we can set up the following proportion:
(winners/players) = (5/12)
Let's solve for the number of winners among 204 players:
(winners/204) = (5/12)
winners = (5/12) * 204
winners = 85
Therefore, we can expect 85 winners among 204 players if the ratio of winners to players remains the same as last year.
Now let's calculate the potential earnings or losses for the booth. Each player pays $1 for three darts, so the booth will earn 204*1 = $204.
Out of the 204 players, we expect 85 winners. Each winner receives a prize worth $4, so the total cost of prizes is 85*4 = $340.
The booth earns $204 and spends $340 on prizes, resulting in a loss of $136.

The Correct option Will be An event is unusual if it has a low probability of occurring The choice of a cutoff should consider the context of the problem i.e. A.
What exactly is probability?The likelihood of an event is expressed by probability. The occurrence of a random event is the subject of this mathematical field of study. The value is between zero and one. In mathematics, probability is a tool for calculating the likelihood that certain events will take place.
Probability is the possibility of something happening. The probability distribution also makes use of this central concept in probability theory. We must first ascertain the total number of possibilities before calculating the likelihood that a specific event will occur.
What does it mean when an event is unusual or out of the ordinary?When something unusual happens, it does not happen frequently in terms of sight or sound.
The probability that an event will occur P(E) = the number of positive outcomes divided by the total number of outcomes.
Now,
As an unusual event has low probability because it does not happen often and The same cutoff should not be used to detect unexpected events all of the time. Choosing a cutoff is subjective, and it should consider the repercussions of erroneously labelling an occurrence as rare.

2. Find the number of ways in which 9 different computer games can be shared out between Wendy, Jim and Hannah so that each person receives an odd number of computer games.
Using combinatorics, there are 1926 ways to distribute 9 different computer games among Wendy, Jim, and Hannah so that each person receives an odd number of games.
What is the number of ways the game is shared between themIf each person receives an odd number of games, then the number of games must be 1, 3, 5, or 7. There are four odd numbers to choose from.
We can use combinatorics to find the odd number in each turn.
Let's consider each odd number in turn.
If each person gets 1 game, then we are looking for the number of ways to choose 3 games out of 9 to distribute. This is simply the number of combinations of 3 things taken from a set of 9 things, which is 9C3, or (9!)/(3!6!) = 84.
If each person gets 3 games, then we are looking for the number of ways to choose 3 games out of 9 to distribute to one person. Once those games have been chosen, we are left with 6 games to distribute to the other two people. The number of ways to choose 3 games out of 9 is again 84, but we must multiply this by the number of ways to choose 3 games out of the remaining 6. This is 6C3, or (6!)/(3!3!) = 20. Therefore, the total number of ways to distribute 9 games with each person getting 3 games is 84*20 = 1680.
If each person gets 5 games, then we are looking for the number of ways to choose 5 games out of 9 to distribute to one person. Once those games have been chosen, we are left with 4 games to distribute to the other two people. The number of ways to choose 5 games out of 9 is 126, and the number of ways to choose 4 games out of the remaining 4 is 1. Therefore, the total number of ways to distribute 9 games with each person getting 5 games is 126*1 = 126.
If each person gets 7 games, then we are looking for the number of ways to choose 7 games out of 9 to distribute to one person. Once those games have been chosen, we are left with 2 games to distribute to the other two people. The number of ways to choose 7 games out of 9 is 36, and the number of ways to choose 2 games out of the remaining 2 is 1. Therefore, the total number of ways to distribute 9 games with each person getting 7 games is 36*1 = 36.
Adding up the number of ways to distribute the games in each case, we get 84 + 1680 + 126 + 36 = 1926.

Use substitution to solve the system. +3x5y = 7 y = +2x4
Answer: To solve the system of equations using substitution, we'll start by rearranging one of the equations so that one of the variables can be expressed in terms of the other. In this case, we'll rearrange the second equation to find y in terms of x.
y = 2x + 4
Next, we'll substitute this expression for y into the first equation:
+3x + 5(2x + 4) = 7
Expanding the right-hand side:
+3x + 10x + 20 = 7
Combining like terms:
13x + 20 = 7
Subtracting 20 from both sides:
13x = -13
Dividing both sides by 13:
x = -1
Finally, we'll use the expression we found for y in terms of x to find the corresponding value of y:
y = 2x + 4
y = 2(-1) + 4
y = -2 + 4
y = 2
So the solution to the system is (x, y) = (-1, 2).

For the required linear function , the height of the candle when the amount of time for burning a candle is 16 hours is equal to 18.8 centimeters.
Let 'h' be the height of the candle.
And 't' be the amount of time used for burning.
Required linear function is :
h = mt + c
When t = 8 hours , h = 20.4centimeters
20.4 = 8m + c ___(1)
When t = 19 hours , h = 18.2centimeters
18.2 = 19m + c ___(2)
Subtract (2) from (1) we get,
20.4 = 8m + c
18.2 = 19m + c
2.2 = -11m
⇒ m = -2.2 / 11
⇒ m = -0.2
Substitute in (1) we get,
20.4 = 8( -0.2 ) + c
⇒ c = 20.4 + 1.6
⇒ c = 22
Now , h = -0.2t + 22
When t = 16 hours
⇒ h = -0.2(16) + 22
⇒ h = -3.2 + 22
⇒ h = 18.8 centimeters
Therefore, the height of the candle when amount of time of burning is 16 hours is equal to 18.8 centimeters.
