The probability of selecting a person at random is p(w and f) is 0.0216 or 2.16%.

The probability of an event occurring and another event occurring is found by using the multiplication rule of probability, which states that the probability of two events occurring together is equal to the product of the probabilities of each event occurring independently.

In this case, we are looking for the probability of a person being born in the winter (p(w)) and the probability of a person being born in the fall (p(f)), so we would calculate:

p(w and f) = p(w) * p(f)

Using the information provided, we know that:

p(w) = 12% = 0.12

p(f) = 18% = 0.18

So, to find p(w and f), we would multiply:

p(w and f) = 0.12 * 0.18 = 0.0216 or 2.16%

A) 20 ft B) 80 ft C) 40 ft D) 24 ft. The equation y=-1/640 x2 + 1/4 x + 20 can be used to calculate the height, distance, maximum height, and horizontal distance of the stunt motorcyclist's jump.

A) The motorcycle's height when it lands on the ramp is 20 feet. This can be calculated by plugging 0 in for x in the equation y=-1/640 x2 + 1/4 x + 20. When you plug in 0 for x, you get y=-1/640 (0)2 + 1/4 (0) + 20, which simplifies to y=20. This means that when the motorcycle lands on the ramp, it is 20 feet off the ground.

B) The distance between the ramps is 80 feet. This can be calculated by finding the value of x when y=20. Solve the equation y=-1/640 x2 + 1/4 x + 20 for x when y=20. When you solve this equation, you get x=80. This means that the distance between the ramps is 80 feet.

C) The horizontal distance the motorcycle has traveled when it reaches its maximum height is 40 feet. This can be calculated by finding the value of x when y=24. Solve the equation y=-1/640 x2 + 1/4 x + 20 for x when y=24. When you solve this equation, you get x=40. This means  that the horizontal distance the motorcycle has traveled when it reaches its maximum height is 40 feet.

D) The motorcycle's maximum height above the ground is 24 feet. This can be calculated by finding the maximum value of y in the equation y=-1/640 x2 + 1/4 x + 20. When you calculate the maximum value of y, you get y=24. This means that the motorcycle's maximum height above the ground is 24 feet.

What is a bar diagram?

Bar graphs or bar charts are visual depictions of groups of data that are made up of vertical or horizontal rectangular bars with lengths that are equal to the data's measure.

A bar diagram can be used to show a percent of change by comparing the size of two or more bars. The bars can represent the original value and the final value, and the difference in size between the two bars will indicate the percent of change.

For example, if the original value is represented by a bar that is 10 units tall and the final value is represented by a bar that is 12 units tall, the percent of change would be 20% (the difference in height between the two bars divided by the original value).

The percent of change can also be labeled or annotated on the graph.

E(Y|X) is the conditional expectation of Y given X. We can use the law of iterated expectations to show that E(u) = 0.

This law states that E(E(X|Y)) = E(X). Therefore, E(u) = E(Y - E(Y|X)) = E(Y) - E(E(Y|X)) = E(Y) - E(Y) = 0.

b. We can use the law of iterated expectations again to show that E(uX) = 0. This law states that E(E(XY|Z)) = E(X)E(Y|Z). Therefore, E(uX) = E(YX - E(YX|X)) = E(YX) - E(E(YX|X)) = E(YX) - E(Y)E(X) = 0.

c. Let Ỹ = g(x) denote a different prediction of Y using X and let v = Y - Ỹ denote its error. We can use the equation h(X) = g(x) - E(Y|X), so that v = [Y - E(Y|X)] - h(X). Using this equation, we can derive E(v2) = E[(Y - E(Y|X))2] - 2E[(Y - E(Y|X))h(X)] + E[h(X)2]. Since E(Y - E(Y|X)) = 0, this reduces to E(v2) = E[h(X)2] < E[(Y - Ỹ)2], which shows that E[(Y - Ỹ)?] > E[(Y - Ỹ)2].

A dividend is a portion of a company's profits and retained earnings that it distributes to its shareholders and owners. When a company makes a profit and accumulates retained earnings, those earnings can be reinvested in the company or distributed to shareholders as a dividend.

The amount of dividends you will receive if you own 10,000 shares can be calculated as follows:

Dividend per share = Share price * dividend yield

Dividend per share = $18 * 0.025

Dividend per share = $0.45

For example, for x = 3, y = 4 and y = -4 both satisfy the equation.

For a discrete random variable X that takes on a finite or countably infinite number of possible values, we determined p(X=x) for all of the possible values of X and called it the probability mass function ("p.m.f").

For continuous random variables, as we shall soon see, the probability that X takes on any particular value x is 0. That is, finding p(X=x) for a continuous random variable X is not going to work. Instead, we'll need to find the probability that X falls in some interval a,b that is, we'll need to find.

The best estimate for the solution to a system of linear equations can be found by using the Substitution Method.

To solve for the solution, the equations must be written in the form y = mx + b. The slope, m, and the y-intercept, b, of each equation can then be calculated. The x-coordinate of the solution can be found by setting the two equations equal to each other to create an equation in one variable. This equation can then be solved for x. The y-coordinate of the solution can be found by substituting the x-coordinate into one of the original two equations. The ordered pair that is the estimated solution can then be formed.

For example, consider the system of equations y = 3x + 2 and y = -x + 5. The slope of the first equation is m1 = 3, and the y-intercept is b1 = 2. The slope of the second equation is m2 = -1, and the y-intercept is b2 = 5. Setting the two equations equal to each other yields 3x + 2 = -x + 5. Solving for x gives x = 3. Substituting this x-coordinate into either of the original equations yields y = 3(3) + 2 = 11. The ordered pair that is the estimated solution to the system is (3, 11).

The number of ways to partition set S into three sets A, B, and C of equal sizes is 495.

The number of ways to partition S into three sets of equal sizes can be calculated using the formula: nPr=n!/(r!(n−r)!), where n is the total number of elements in the set and r is the number of elements in each partitioned set.

In this case, n=12 and r=4. Therefore, the number of ways to partition S into three sets A, B, and C of equal sizes is 12P4 = 12!/(4!(12−4)!) = 495.

In calculation way step by step,

We know that n = 12 and r = 4.

Calculate 12!.

12! = 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 479001600

Calculate 4!.

4! = 4 x 3 x 2 x 1 = 24

Calculate (12 - 4)!

(12 - 4)! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40320

Calculate nPr.

nPr = n!/(r!(n - r)!) = 479001600/(24 x 40320) = 495
