a. You replace each card before selecting the next card.

The probability of drawing a heart on the first draw is 13/52 or 1/4. The probability of drawing a heart on the second draw is also 13/52 or 1/4. And the probability of drawing a heart on the third draw is also 13/52 or 1/4.

Since the events are independent, we can multiply the probability of each event to find the probability that all three cards are hearts: (1/4) * (1/4) * (1/4) = 1/64.

b. You do not replace each card before selecting the next card.

The probability of drawing a heart on the first draw is 13/52 or 1/4. The probability of drawing a heart on the second draw is 12/51 since we already drew a heart before, the total number of cards left in the deck is 51. The probability of drawing a heart on the third draw is 11/50 since we already drew 2 hearts before, the total number of cards left in the deck is 50.

The probability that all three cards are hearts is (1/4) * (12/51) * (11/50) = 0.0217 or approximately 2.17%.

It's important to note that in the first case the probability of drawing a heart on the second and third draw is still 1/4 because we are replacing the cards back before drawing the next one, so all 52 cards are available again. While on the second case, we don't replace the cards back and that's why the probability of drawing a heart on the second and third draw is different.Answer:

The current weight of Aadan's dog is approximately 26.67 kg.

What is weight ?

Weight is a measure of the force of gravity on an object. The weight of an object is equal to the force exerted on the object by gravity. The weight of an object is typically measured in units of force such as newtons (N) or pounds (lb). On Earth, the weight of an object is equal to its mass multiplied by the acceleration due to gravity, which is approximately 9.8 m/s².

Let's call the current weight of Aadan's dog as "W".

As per the information given,

Aadan's dog was a puppy and it weighed 8 kg which is 30% of it's current adult weight.

So, 8kg = 30/100*W

We can find the current weight of Aadan's dog by solving the equation above:

8 = 30/100W

8 = 3/10W

8 = 0.3W

W = 8/0.3

W = 8/(3/10)

W = 8(10/3)

W = 8*3.333

W = 26.666 kg ( approx 26.67 kg)

According to the given statement, 3x^3y^4 represents the length of the room.

Its length w is calculated using the formula h = A/w if you have an area A and a width w. Its length can be determined using the formula h = P/2w if you know its perimeter (P) and width (W). The length is given by h = (d2w2) if the diagonal d and width w are present.

Four sides, four corners, and four 90° right angles make up the closed, 2-D shape of a rectangle. A rectangle has parallel, equal sides on either side.

The area of a square box is length x width, so that we can set up the calculation:

length x (2x³y²) = 6x6y8

To find the length of the court, we can divide both sides by 2x³y²:

length = (6x6y8) / (2x³y²)

The inverse function of f(x) = x^3 - 1 is f^-1(x) = (x + 1)^(1/3).

What is the inverse of a function?

An inverse function is a function that returns the original value for which a function has given the output. If f(x) is a function that gives output y, then the inverse function of y, i.e. f-1(y) will return the value x.

The inverse of a function f(x) is denoted as f^-1(x), and it is defined as the function that "undoes" f(x).

To find the inverse of a function, we need to swap the roles of x and y, and then solve for y in terms of x.

Given f(x) = x^3 - 1, the inverse function f^-1(x) is the function such that:

f(f^-1(x)) = x

f^-1(f(x)) = x

So we need to solve for x in terms of y.

x^3 - 1 = y

x = (y + 1)^(1/3)

Therefore, the inverse function of f(x) = x^3 - 1 is f^-1(x) = (x + 1)^(1/3).

Answer: Is there an answer for 1/2? I'm not sure.

Step-by-step explanation: If you look at the line it's going up by one and over by 2.

To solve for slope (Rate of Change) you need to find the change and y over the change in x. (y2-y1) divided by (x2-x1) take two points on the graph that is touching a line.

Two points on your graph is (2,2), and (6,4). You would take the second y which is 4 and subtract it from the first y which is 2. (4-2 = 2). Then you take the second x (6) and subtract it from the second y (2). (6-2 = 4). Now that you have the change and x over the change in y. you divide the top number by the bottom number. If it's a fraction just simplify it. (2/4 = 1/2). I'm not that good at explaining but I hope this helps a lot!

The standard form of polynomial is to write the polynomial so that the term with the highest power of the variable comes first, followed by the other terms in order of descending powers of the variable.

A polynomial in standard form requires that the polynomial be written in descending order of exponents. Polynomials are written in standard form for ease of computation. A polynomial is in its canonical form when it is expressed with the highest order term first, followed by the higher order terms, and so on. For example: 14x⁴ - 5x³ - 11x² - 11x + 8. You can see that in this standard form polynomial, the exponents are ordered in descending powers. These algebraic equations are called polynomials. Procedure for writing polynomials in standard form:

The solutions of the equation x⁴ - 5x² - 36 = 0 are: x = -3, x = 3, x = 2i and x = -2i

Consider given equation x⁴ - 5x² - 36 = 0

Let us assume that x² = p

so, we get an equation,

p² - 5p - 36 = 0

Now we solve above quadratic equation.

p² - 5p - 36 = 0

using the Quadratic Formula where

a = 1, b = -5, and c = -36

[tex]\Rightarrow p=\frac{-b\pm \sqrt{b^2 -4ac} }{2a}\\\\\\ \Rightarrow p = \frac{5\pm \sqrt{25+144} }{2}\\\\\\\Rightarrow p = \frac{5\pm \sqrt{169} }{2}\\\\\\ \Rightarrow p=\frac{5\pm 13 }{2}[/tex]

So, p = 9 and p = -4

But p = x²

So, x² = 9 OR x² = -4

Inequality 5 > 6 is an example of an inequality whose solution is an empty set.

What is inequality?

An inequality is a statement that compares two expressions using one of the following mathematical symbols: <, >, ≤, ≥, ≠. It shows the relationship between the values of the expressions, but unlike an equation, it does not show that the expressions are equal.

For example, the inequality 3x + 4 > 7 compares the value of the expression 3x + 4 to the value of 7. It shows that 3x + 4 is greater than 7 for all values of x.

An inequality that has an empty set as its solution is one that has no solutions. For example, inequality 5 > 6 is an example of an inequality whose solution is an empty set because it is impossible for any value of x to satisfy the inequality. Any value of x will be less than 6 so it is impossible for x to be greater than 6.

Hence, Inequality 5 > 6 is an example of an inequality whose solution is an empty set.
