The probability that the second card is yellow after one green card is drawn and not replaced from a deck of 8 (3 yellow, 5 green) cards is 3/7. The correct answer is option b) 3/7.
To find the probability that the second card is yellow after drawing one green card (and not replacing it), we can follow these steps:
Determine the total number of cards in the deck after the first green card is drawn. Initially, we have 3 yellow + 5 green = 8 cards. After drawing one green card, there are 7 cards left (2 yellow and 5 green).Since one green card is drawn and not replaced, the number of green cards that remain in the deck is now 4, and the total number of cards left in the deck is 7.Calculate the probability of drawing a yellow card from the remaining 7 cards. There are still 3 yellow cards, so the probability is 3 yellow cards divided by the 7 total remaining cards.Thus, the probability that the second card is yellow is 3/7, which is corresponding to (b).

What is probability?
probability is the ratio of the number of favorable outcomes and the total number of possible outcomes. The chance that a particular event (or set of events) will occur expressed on a linear scale from 0 (impossibility) to 1 (certainty), also expressed as a percentage between 0 and 100%.
Given:
There are 108 flights from an airport, 20 of which are longer than 3 hours.
According to given question we have
By the use of probability we get,

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first equation be represented as A
Now , the value of A is
A = 4cd - 25c² - 0.16d² be equation (1)
On simplifying the equation , we get

Which equation is the inverse of y = 9x^2 - 4?
The inverse of
[tex]y = 9x^2 - 4[/tex]can be mathematically given by y = +/- sqrt((x + 4) / 9), yet it is not considered a function because it does not pass the horizontal line test.
Explanation:The inverse of a function flips the x and y values such that each x becomes a y and vice versa. However, it's important to mention that not all functions have an inverse that is also a function. Your provided function,
[tex]y = 9x^2 - 4[/tex], is a quadratic function (a type of polynomial function), and it does not have an inverse that can also be called a function because it does not pass the horizontal line test.
Yet, mathematically it can be found by swapping x and y and solving for y. If we do that, we have:
Switch the roles of y and x, we get: x = [tex]9y^2 - 4[/tex].Solving for y, we have: y = +/- sqrt((x + 4) / 9), where "sqrt" denotes the square root.Again, this is not a function due to the presence of the plus/minus symbol.

The mass in a pendulum clock completes one complete swing in 1.00 s . what is the length of the rod?
The length of the pendulum or rod in a pendulum clock that completes one swing in 1.00 seconds is approximately 0.25 meters, or 25 centimeters.
Explanation:The time taken by the pendulum to complete one full swing is also known as its period, denoted by T. You indicated that in this case the pendulum completes one swing in 1.00 seconds. To determine the length of the pendulum, or rod, we use the formula for the period of a simple pendulum, T=2π√(L/g), where L is the length of the pendulum and g is the acceleration due to gravity (approximately 9.8 m/s² on Earth).
Setting T to 1.00 seconds and g to 9.8 m/s², we can solve this equation for L:
L = (T² * g) / 4π²
Substituting the given values:
L = (1.00² * 9.80) / 4π²
This gives us a pendulum length of approximately 0.25 meters, or 25 centimeters.

There are 19.6.grams of protein in 4 ounces of cashews. About how many gram of protein are in one ounce of cashews?
Final answer:
To find the protein content in one ounce of cashews, divide 19.6 grams by 4 ounces, resulting in approximately 4.9 grams of protein per ounce.
Explanation:
To find out how many grams of protein are in one ounce of cashews, we need to divide the total amount of protein by the number of ounces. Given that there are 19.6 grams of protein in 4 ounces of cashews, we can calculate the amount of protein in one ounce by performing the following calculation:
Amount of protein in one ounce = Total grams of protein / Number of ounces
Amount of protein in one ounce = 19.6 grams / 4 ounces
Amount of protein in one ounce = 4.9 grams
Therefore, there are approximately 4.9 grams of protein in one ounce of cashews.

It also covers for the damage to others property inflicted by you or when any visitor damages your property.
Final answer:
Insurance that pays for damages to houses or businesses is called property/homeowners insurance, which covers a range of risks and includes liability coverage. The policy generally provides cash value or replacement value for the insured property and possessions.
Explanation:
The insurance that pays for damages to houses or businesses is called property/homeowners insurance. This type of insurance is crucial as it provides a safety net against various risks such as fire, wind damage, theft, and falling trees. Besides covering damages to the physical structure of a home, homeowners insurance often includes liability coverage, which protects the homeowner up to a certain amount if someone is injured on their property, except in cases where the law is being broken.
Furthermore, it is worth noting that an insurance policy generally has a cash value. If a house is destroyed, the policy will pay out the current value of the house. A replacement value policy is recommended, as it will adjust the payout based on inflation and cover the cost to replace the home, including other structures like garages and pools as well as personal property within the house.

Manny has a credit card with a line of credit at $4,000. He made the following purchases: $425.36, $358.33, $377.11, and $90.20. What is Manny's available credit?
Manny's available credit is $2,749.00.
Explanation:To find Manny's available credit, we need to subtract the total of his purchases from his line of credit. Manny's purchases total $425.36 + $358.33 + $377.11 + $90.20 = $1,251.00. So, to find his available credit, we subtract $1,251.00 from his line of credit of $4,000.00. The available credit is $4,000.00 - $1,251.00 = $2,749.00.

A 25-foot ladder is placed against a vertical wall of a building, with the bottom of the ladder standing on level ground 6 feet from the base of the building. How high up the wall does the ladder reach?
Round to the nearest hundredth
The ladder reaches a height on the wall of approximately 24.29 feet.
Explanation:To find the height on the wall that the ladder reaches, we can use the Pythagorean theorem. The ladder, the wall, and the ground form a right triangle. The ladder is the hypotenuse, the distance from the base of the building to the ladder is one leg, and the height on the wall that the ladder reaches is the other leg. Using the Pythagorean theorem, we have:
a² + b² = c²
where a is the distance from the base of the building to the ladder (6 feet), b is the height on the wall, and c is the length of the ladder (25 feet).
Solving for b, we have:
b = √(c² - a²)
Substituting the given values, we get:
b = √(25² - 6²) = √(625 - 36) = √589 ≈ 24.29 feet
Therefore, the ladder reaches a height on the wall of approximately 24.29 feet.

see below for a drawingthe area of one of the trapezoids is 20 units²Step-by-step explanation:
No direction or other information about the desired parallelogram is given here, so we drew one arbitrarily. Likewise for the segment cutting it in half. It is convenient to have the bases of the trapezoids be the sides of the parallelogram that are 5 units apart.
The area of one trapezoid is ...
A = (1/2)(b1 +b2)h = (1/2)(3+5)·5 = 20 . . . . square units
The sum of the trapezoid base lengths is necessarily the length of the base of the parallelogram, so the area of the trapezoid is necessarily 1/2 the area of the parallelogram. (The area is necessarily half the area of the parallelogram also because the problem has us divide the parallelogram into two identical parts.)
