So, the variance of the number of tornadoes in a year given that at least one tornado occurs is 3.
The Poisson distribution is a discrete probability distribution that describes the number of events that occur in a fixed interval of time or space, given the average number of events per interval.
For a Poisson distribution with mean λ, the variance is equal to λ.
Given that at least one tornado occurs in a year, the mean number of tornadoes is 3. Therefore, the variance is also equal to 3.
So, the variance of the number of tornadoes in a year given that at least one tornado occurs is 3.
It's worth noting that this result is based on the assumption that the number of tornadoes follows a Poisson distribution with mean 3, which may not always be the case in real-world scenarios. The actual number of tornadoes in a given year can be influenced by various factors such as climate, weather patterns, and geography.

ben participates in a prize draw. he receives one prize that is equally likely to be worth $5, $10 or $20. jamie participates in a different prize draw. she receives one prize that is equally likely to be worth $30 or $40. what is the probability that the total value of their prizes is exactly $50?
The probability of getting a total value of $50 is 1/6.
There are three possible outcomes for Ben's prize: $5, $10, or $20.
There are two possible outcomes for Jamie's prize: $30 or $40.
Therefore, there are 3 x 2 = 6 total possible outcomes for the combined value of their prizes.
To find the probability that the total value of their prizes is exactly $50, we need to find the number of outcomes that result in a total value of $50, and divide that by the total number of possible outcomes.
The only way to get a total value of exactly $50 is that Ben wins $20 and Jamie wins $30. This is only one combination out of 6 possible combinations. So the probability of getting a total value of $50 is 1/6 or approximately 0.166.

what is the area of a triangle if the legs ar5e x and y long. if the first leg of the triangle is x and the length of the second leg is y, the formula
The area of a triangle is Area = sqrt(s(s-x)(s-y)(s-c)).
The area of a triangle can be found using the Heron's formula if we know the lengths of all three sides, or using the formula (1/2) * x * y if we know the lengths of two legs and the triangle is a right triangle.
In the case where the legs of the triangle are x and y long, if we don't know if the triangle is a right triangle, we can't use the formula (1/2) * x * y. However, we can use Heron's formula to calculate the area. Heron's formula states that the area of a triangle is equal to the square root of s(s-a)(s-b)(s-c), where s is the semi-perimeter of the triangle and a, b, and c are the lengths of the three sides.
In this case, since we know the lengths of the two legs x and y, we can find the area of the triangle using Heron's formula as follows:
s = (x + y + c)/2
Area = sqrt(s(s-x)(s-y)(s-c))
Where c is the length of the hypotenuse of the triangle, this information is not provided, so we cannot calculate the area of the triangle.
Therefore, The area of a triangle is Area = sqrt(s(s-x)(s-y)(s-c)).

Solve the given differential equation by separation of variables.y ln x * (dx/dy) = [(y+1)/x]^2[(y^2)/2] + 2y + ln|y| =
The solution of the given differential equation is
x ln x - (x/2)(y+1)^2 + (y^3)/3 + 2y^2 + y ln|y| + c = 0
The given differential equation can be written as
ln x * (dx/dy) = [(y+1)/x]^2[(y^2)/2] + 2y + ln|y|
To solve this equation, we will use separation of variables. This means that we need to separate the terms containing 'x' and the terms containing 'y' on different sides of the equation.
We can rearrange the equation as,
ln x * (dx/dy) - [(y+1)/x]^2[(y^2)/2] - 2y - ln|y| = 0
Now, let us separate the terms containing 'x' from terms containing 'y':
ln x * (dx/dy) = [(y+1)/x]^2[(y^2)/2] + 2y + ln|y|
On one side of the equation, we have ln x * (dx/dy) and on the other side, we have [(y+1)/x]^2[(y^2)/2] + 2y + ln|y|.
Now, we can integrate both sides of the equation with respect to 'y':
∫ ln x * (dx/dy) dy = ∫ [(y+1)/x]^2[(y^2)/2] + 2y + ln|y| dy
Integrating both sides of the equation, we get
x ln x - (x/2)(y+1)^2 + (y^3)/3 + 2y^2 + y ln|y| + c = 0
where c is a constant of integration.
Therefore, the solution of the given differential equation is
x ln x - (x/2)(y+1)^2 + (y^3)/3 + 2y^2 + y ln|y| + c = 0

If 10% of a number is 26 and 25% of the same number is 65, what is 15% of that number
15% of that number is 39.
What is a percentage?
A percentage is a way to express a number as a fraction of 100. It is commonly used to represent a proportion or ratio of a number to a whole. For example, 10% of a number means 10/100 or 1/10 of that number, 25% means 25/100 or 1/4 of that number, and 15% means 15/100 or 3/20 of that number.
To find 15% of a number, if we know that 10% of it is 26, and 25% of it is 65, we can use algebra:
Let X be the number we're trying to find
10% of X = 0.10X = 26
25% of X = 0.25X = 65
We know that 15% is between 10% and 25% so we can use the proportionality between them:
15% of X = 0.15X = (15/10)*26 = 39
Hence, 15% of that number is 39.

Answer:
There are several ways to look at this
Consider the interior angles of a triangle:
33 + A = 90
52 + B = 90
85 + A + B = 180 interior angles of a triangle must sum to 180
So 180 - 85 = 95 which completes the triangle and would be EKD
Or 33 counterclockwise + X clockwise + 52 counter clockwise = 0
X must be 85 and is exterior to EKD and again
EKD = 180 - 85 = 95

∠P measures 30° more than the measure of its supplement. What is the measure of ∠P in degrees?
Applying the definition o a supplement of an angle, the measure of angle P in degrees is: 105°.
What is the Supplement of an Angle?The supplement of an angle is defined as the angle measure that is added to the angle to give a sum of 180 degrees.
For example, the supplement of angle X is 180 - measure of angle X.
Given the following:
Supplement of angle P = 180 - measure of angle P
Measure of angle P = (180 - measure of angle P) + 30 degrees
Therefore:
(180 - m<P) + [(180 - m<P) + 30] = 180
Open the parentheses:
180 - m<P + 180 - m<P + 30 = 180
Combine like terms:
390 - 2(m<P) = 180
390 - 180 = 2(m<P)
210 = 2(m<P)
210/2 = 2(m<P)/2
105 = m<P
m<P = 105°

Answer:
To find the angle subtended by a chord at the center of a circle, we can use the formula:
θ = 2 * arcsin (c / 2r)
where θ is the angle subtended by the chord, c is the length of the chord, and r is the radius of the circle.
Step 1: Substitute the given values into the formula
θ = 2 * arcsin (13.2 / (2 * 9.4))
Step 2: Simplify the equation
θ = 2 * arcsin (13.2 / 18.8)
Step 3: Use a calculator or a math table to find the value of arcsin
arcsin (13.2 / 18.8) = 0.636 radians
Step 4: Multiply the value obtained by 2

60% of the people in the room are married men.
We can use the information that the probability of a randomly selected woman being single is 2/5 to find the fraction of people in the room who are married men.
Let's call the fraction of people in the room who are married men x. The fraction of people in the room who are single women is (2/5) and the fraction of people in the room who are married men and their wives is (1-x)
Since there are only single women and married men with their wives at the party, we know that the sum of the fractions of single women and married men and their wives must be 1.
(2/5) + (1-x) = 1
We can solve this equation for x:
x = 1 - (2/5) = 3/5
So the fraction of people in the room who are married men is 3/5 or 0.6

How do we use the CONVERSE of the Pythagorean Thm. to determine if a triangle is acute, obtuse, or right
The angles in a triangle are less than 90 degrees, the triangle is acute, greater than 90 degrees, the triangle is obtuse, and exactly 90 degrees, the triangle is a right triangle.
What is the converse of the Pythagorean theorem?
The converse of the Pythagorean theorem states that if the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other two sides, then the triangle is a right triangle.
To determine if a triangle is acute, obtuse, or right, we can use the following:
If all the angles in a triangle are less than 90 degrees, the triangle is acute.
If one angle in a triangle is greater than 90 degrees, the triangle is obtuse.
If one angle in a triangle is exactly 90 degrees, the triangle is a right triangle, using the converse of the Pythagorean theorem, c² = a² + b².

Why are there 2 answers in an absolute value equation?
An absolute value equation can have two solutions, one for the positive case and one for the negative case. It's important to check both cases to make sure that we have found all of the solutions to the equation.
An absolute value equation is an equation that contains an absolute value function. The absolute value of a number is defined as the distance of that number from zero on the number line. It is always non-negative.
When solving an absolute value equation, we need to consider two cases: the case where the value inside the absolute value sign is positive, and the case where it is negative.
For example, if we have the equation |x| = 2, we can solve it by first considering the case where x is positive:
x = 2 (because the distance from zero is 2 on the positive side of the number line)
Alternatively, we can consider the case where x is negative:
x = -2 (because the distance from zero is 2 on the negative side of the number line)
So in this example, there are two solutions: x = 2 or x = -2.

Two players take turns putting pennies on a round table, one penny per turn, withoutpiling one penny on top of another. The player who cannot place a penny loses. Design a winningstrategy for the first player.
The first player will eventually win, when the second player runs out of free slots.
On the first move place the coin on the center of the table.
Then player B will place his coin anywhere on the table.
Now, you put your coin on the line of diameter passing through the coin placed by player B, at the same distance away from the boundary of the circle ( mimic his placement on the opposite side of the table).
If player A has space to place a coin, so will player B. Player B will run out of place before player A.
The first player will eventually win, when the second player runs out of free slots.
