According to the flood recurrence interval equation, a flood that occurs in 2021, after 149 years of record keeping, and is the third largest ever recorded has a recurrence interval of approximately 50 years.
The flood recurrence interval equation is a statistical method used to estimate the likelihood of a flood of a certain magnitude occurring in any given year. It is based on historical records of floods and takes into account the size and frequency of floods that have occurred in the past.
In this case, the flood that occurred in 2021 is the third largest ever recorded. Based on the historical records of floods over the past 149 years, this flood has a recurrence interval of approximately 50 years. This means that there is a 2% chance of a flood of this magnitude occurring in any given year.
It is important to note that the flood recurrence interval equation is not a perfect predictor of future floods. It is only an estimation based on historical records. Other factors such as climate change and changes in land use can also impact the likelihood and severity of floods.
In conclusion, the recurrence interval for a flood that occurred in 2021, after 149 years of record keeping and is the third largest ever recorded is approximately 50 years. However, it is important to remember that the accuracy of this estimation may vary based on several factors.

West Ridge High School is holding an honor roll banquet. It costs $95 to rent the cafeteria plus $13 for each person attending the banquet. If C(x) represents the total cost and x represents the number of people attending the banquet, which equation shows the total cost?
A C(x)=95x – 13
B C(x)=13x – 95
C C(x)=95x +13
D C(x)=13x +95
The equation that represents the total cost is C(x)=13x +95. (option d)
The problem tells us that it costs $95 to rent the cafeteria, which is a fixed cost that doesn't change based on the number of people attending. However, the cost per person is $13. So, if we have x number of people attending the banquet, the total cost would be $95 (for the cafeteria rental) plus $13x (for each person attending).
Now, we need to represent this relationship using an equation. An equation is a mathematical statement that shows the relationship between two quantities. In this case, the two quantities are the total cost and the number of people attending the banquet.
Using the third equation, C(x) = 95x + 13, we get:
C(0) = 95(0) + 13 = 13
This makes sense, because if there are 0 people attending, the total cost should just be the rental fee of $95.
Now, let's try the last equation, C(x) = 13x + 95:
C(0) = 13(0) + 95 = 95
This gives us the correct rental fee of $95, but it doesn't take into account the cost per person. This equation takes into account the rental fee of $95 as well as the $13 cost per person attending the banquet.
Hence the correct option is (d).

five card hand is dealt at random from a standard 52 card deck. find the probability of having c. exactly 2 kings and the ace of spades given that you have at least one ace
The five-card hand is dealt at random from a standard 52-card deck. the probability of having exactly 2 kings and the ace of spades given that you have at least one ace is 2.9%.
To find the probability of having exactly 2 kings and the ace of spades given that you have at least one ace
When a five-card hand is dealt at random from a standard 52-card deck is as follows:
There are 52 cards in a standard deck. Therefore, there are 4 Kings and 1 Ace of Spades. The number of ways in which we can select 2 Kings from 4 Kings is:
₄C₂ = \((4 * 3)/(2 * 1)\)
= 6
The number of ways in which we can select the Ace of Spades from 1 Ace is:
₁C₁ = 1
The remaining 2 cards are non-Kings and non-Ace of Spades cards. So, there are 44 such cards. The number of ways in which we can select 2 cards from 44 cards is:
₄₄C₂ = \((44 * 43)/(2 * 1)\)
= 946
Therefore, the total number of ways in which we can select 2 Kings and 1 Ace of Spades and 2 non-Kings and non-Ace of Spades cards is:
\(6 * 1 * 946\) = 5676
There are 4 Aces in a standard deck. The number of ways in which we can select at least one Ace from 4 Aces is:
₄C₁ + ₄C₂ + ₄C₃ + ₄C₄ = 4 + 6 + 4 + 1
= 15
Therefore, the probability of having exactly 2 kings and the ace of spades given that you have at least one ace when a five-card hand is dealt at random from a standard 52-card deck is:
P(exactly 2 Kings and the Ace of Spades | at least one Ace) = (Number of ways in which we can select 2 Kings and 1 Ace of Spades and 2 non-Kings and non-Ace of Spades cards) / (Number of ways in which we can select at least one Ace)
= 5676/15
= 378.4 or 0.029 or 2.9%.
Therefore, the required probability is 0.029 or 2.9%.

Mr. Brownwood invests a certain amount of money at 9% interest and $1,800 more than that amount in another account at 11% interest. At the end of one year, he earned a total of $818 in interest. How much money was invested in each account?
$3,500 at 9%;
$4,300 at 11%
$3,100 at 9%;
$4,900 at 11%
$3,400 at 9%;
$3,200 at 11%
Answer:
$3100 is invested at 9%
$4900 is invested at 11%
Step-by-step explanation:
Let's take "x" be the amount invested at 9%.
(x + 1800) is invested in another account at 11%.
The interest amount earned by the two accounts is $818.
Here we can use the simple interest formula and find the amount invested in each account.
Simple interest (I) = , where P- is the principal , N is the number of years and R is the interest rate.
Simple interest =
0.09x + 0.11(x+1800) = 818
Now we have to simplify and find the value of x .
Use the distributive property and simplify the second term.
0.09x + 0.11x + 198 = 818
0.2x + 198 = 818
0.2x =818 - 198
0.2x = 620
x = 620/0.2
x = 3100.
So $3100 is invested at 9%
x + 1800 = 3100 + 1800
= $4900
$4900 is invested at 11%
Hope this helped.

Find the present ages of the sister and her brother.
Answer:
bother = 6 years ; sister = 12 years
Step-by-step explanation:
s = sister
b = brother
s - b = 6
s * b = 4(s+b)
s = b + 6
b(b+6) = 4(b+6 + b)
b² + 6b = 4(2b + 6)
b² + 6b = 8b + 24
b² + 6b - 8b - 24 = 0
b² - 2b - 24 = 0
(b-6)(b+4) = 0
b = 6
b = -4 (impossible because an age can’t be negative)
s = 6 + 6
s = 12

In greedy method, A locally optimal of solution is generated
Greedy algorithms
Greedy algorithms construct a solution piece by piece, selecting the next portion in such a way that it provides an immediate benefit.
This method never reconsiders earlier decisions. This method is most commonly used to tackle optimization problems. Greedy algorithms employ a problem-solving procedure to progressively build candidate solutions, to approximate the global optimum, by obtaining better and better locally optimal solutions at each stage.
The property states that the globally optimum solution may be determined by first determining the locally optimal solution (Greedy). A Greedy algorithm's decision may be influenced by previous decisions but not by future ones.
Globally Optimal Solution
A globally optimal solution is one where there are no other feasible solutions with better objective function values. A locally optimal solution is one where there are no other feasible solutions in the vicinity with better objective function values.
It makes one Greedy decision after another iteratively, reducing the given problem to a smaller one.
Greedy is an algorithmic paradigm that assembles a solution piece by piece, constantly selecting the next component that provides the greatest evident and immediate advantage.

Keshav and Noel started to cycle together from Nehru Park. Keshav takes a break to drink water after (k hours), where k is the first smallest prime natural number. Noel takes a break to drink water after (n hours), where n is the fifth smallest composite natural number.
Calculate the LCM (k, n) and HCF (k, n).
Answer:
LCM (k, n) = 10 and HCF(k, n) = 2
Step-by-step explanation:
The given parameters are;
The time after which Keshav takes a break = k hours
The value of k = The first smallest prime natural number
Therefore, by mathematical definition, k = 2
The time after which Noel takes a break = n hours
The value of n = The fifth smallest composite natural number
The first five composite numbers are given as follows;
4, 6, 8, 9, and 10
Therefore, the fifth smallest composite natural number = 10 = n
The LCM (k, n) = LCM (2, 10) = Least common multiple of 2 and 10 is given as follows;
Dividing by 2, we get;
2/2 = 1, 10/2 = 5
Dividing the result by 5, we get;
5/5 = 1
Multiplying the devisors together gives;
5 × 2 = 10
Therefore, the LCM of 2 and 10 = 10
LCM(2, 10) = LCM (k, n) = 10
The HCF(k, n) = HCF of 2 and 10 = The highest common factor that divides both 2 and 10 is given as follows;
Dividing 2 and 10 by 2 gives;
2/2 = 1 and 10/2 = 5
Therefore, HCF(k, n) = The highest common factor of 2 and 10 = HCF(2, 10) = 2
an economist wants to estimate the mean per capita income (in thousands of dollars) for a major city in california. he believes that the mean income is $21.2, and the standard deviation is known to be $9.3. how large of a sample would be required in order to estimate the mean per capita income at the 95% level of confidence with an error of at most $0.68? round your answer up to the next integer.
By taking the help of the standard deviation, the answer obtained is
n = 719
What is Standard Deviation?
At first it is important to know about Variance.
Variance is the sum of the square of deviation from the mean of the data.
On taking the square root of variance, Standard deviation is obtained.
The formula used for calculating the number of samples required is
\(n=\frac{Z^{2}_{\alpha /2}\times \sigma ^{2}}{e^{2}}\), \(\sigma\) is the standard deviation , e is the error,
Here,
\(\alpha\) = 1 - \(\frac{95}{100}\)
= 1 - 0.95
= 0.05
Critical values of Z = \(\pm\)1.96 [ From the table]
Standard deviation (\(\sigma\)) = 9.3
error (e) = $0.68
On putting the value,
n = \(\frac{1.96^2 \times 9.3^2}{0.68^2}\)
n = 718.5
n = 719

(¬s∨n)∧(¬(n∨F)∨s)
(¬s∨n)∧((¬n∧¬F)∨s)
To apply the next law from the right in the given formula, we first identify the next logical law from the right that can be applied, which is the double negation elimination rule.
We apply this rule to the first term in the formula, (s→¬¬n), which gives us (s→n).
The next law from the right to apply would be the law of double negation again, which simplifies the first term even further by giving us (¬s∨n) instead of (¬s∨¬¬n).
We then apply the implication law to convert the implication in the formula to a disjunction, giving us (¬s∨n)∧(¬(n∨F)∨s).
Finally, we apply De Morgan's law to distribute the negation in the formula, giving us the final answer of (¬s∨n)∧((¬n∧¬F)∨s).
Step-by-step explanation:
Identify the next logical law from the right that can be applied to the given formula. In this case, it is the double negation elimination rule.
Apply the double negation elimination rule to the given formula: (s→¬¬n)∧((n∨F)→s) becomes (s→n)∧((n∨F)→s)
Continue applying relevant logical laws from the right: (s→n)∧((n∨F)→s) becomes (¬s∨n)∧((n∨F)→s)
Apply the implication law to convert the implication in the formula to a disjunction: (¬s∨n)∧((n∨F)→s) becomes (¬s∨n)∧(¬(n∨F)∨s)

Why couldn't Abbie and Ben buy locally-grown corn in May or June in Rhode Island?
Abbie and Ben would not be able to buy locally-grown corn in Rhode Island until late October.
What is amount?Amount is an indefinite quantity of something, typically money, that is to be paid or received. It is often used in the context of a purchase, loan, or other financial transaction. Amounts can be expressed as a numerical value, such as a dollar amount, or as a percentage of the total transaction. In accounting, the term "amount" is used to refer to the total amount of money that is owed or received.
Abbie and Ben could not buy locally-grown corn in May or June in Rhode Island because the growing season for corn in Rhode Island runs from late June through late October. This is the typical growing season for corn in the Northeastern United States and is largely dependent on the region's climate. Corn is a warm-season crop, meaning it requires temperatures of at least 50 degrees Fahrenheit for germination and growth. In early spring, most of Rhode Island is still too cold for corn to be planted. This means that the earliest corn grown in Rhode Island is planted in late June, and it is not harvested until late October. Thus, Abbie and Ben would not be able to buy locally-grown corn in Rhode Island until late October.
