The probability of winning a prize worth more than the price of playing the game is 38%.

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of samples

Given that the percentage of the winning price is:-

Toy = 25%

Soda = 25%

Candy = 37%

Mega win = 13%

The probability of winning a prize worth more than the price of playing the game is calculated as:-

P = ( 25 + 13 ) x 100 / 100

P = 0.38 x 100

P = 38%

Therefore, the probability will be 38%.

The top of the ladder slips down the wall at the rate of 5.6 ft/sec.

What is a rate?

The ratio of two related quantities expressed in several units is known as a rate. The numerator of the ratio indicates the rate of change in the other (dependent) variable if the denominator of the ratio is written as a single unit of one of these quantities, and if it is assumed that this quantity may be modified systematically (i.e., is an independent variable).

Here, we have

Given: A ladder 15ft in length leans against a vertical wall, with the bottom of the ladder 5ft from the wall on the horizontal floor. If at that time the bottom end of the ladder is being pulled away at the rate of 2ft/s .

Let: x = the distance from the base of the ladder to the base of the wall

y = the distance from the tip of the ladder to the base of the wall, we have:

x² + y² = 15²

y² = 15² - 5² = 225 - 25 = 200 => y = 14.14 ft

2x dx/dt + 2y dy/dt = 0

2 * 5 * dx/dt + 2 * 14.14 * (-2) = 0

10 dx/dt = 56.56

dx/dt = 5.6 ft/sec

Consequently, when a1 is provided as 3 and the expression for the following term is a = 5an-1 + 1, the value of a5 is 2031.

An algebraic progression is when there is a continual difference between terms that follow each other in an series. For illustration, the decimal number 5, 7, 9, 11, 13, and 15 is an example of an algebraic expression with a tolerance of two. A advance with a set tolerance among any two consecutive numbers is referred to as a "arithmetic progression" (A.P.). Two types of algebraic progression are plausible: series in mathematics with a finite length A finite geometric evolution is a series with just a finite number of terms. The early, late, allowance, and frequency of terms may all be calculated using the terms in the series.

a1 = 3

a2 = 5 * 3 + 1 = 16

Vito uses 9 liters of water 24 flower pots.

To find: the amount of liters of water (w) it would take to water 40 flower pots.

This means, 9 liters is to 24 pots as w liters is to 40 pots

We write above statement as :

The surface area and weight of the cylinder is 45.1805 in² and 11.107 lbs respectively.

A cylinder is a three-dimensional geometric shape that has two parallel circular bases and a curved lateral surface connecting the bases. The bases are located at opposite ends of the cylinder, and they have the same diameter. The lateral surface is a rectangle that has been bent around the circumference of the circular bases.

The height of a cylinder is the distance between the two bases, and the diameter of the bases is the distance across the circle through its center. The volume of a cylinder can be calculated by multiplying the area of one of its bases by its height. The formula for the volume of a cylinder is:

V = πr²h

where r is the radius of the circular base and h is the height of the cylinder.

Cylinders are commonly used in many real-world applications, such as in the design of pipes, cans, and other containers. They are also commonly used in mathematics and physics, where they can serve as models for objects with cylindrical symmetry, such as pipes and wires.

In summary, a cylinder is a three-dimensional shape with two parallel circular bases and a curved lateral surface connecting the bases. The height of the cylinder is the distance between the bases, and its volume can be calculated using the formula V = πr²h. Cylinders are commonly used in real-world applications and in mathematics and physics.

The following formula can be used to determine the cylinder's volume:

V = π × r² × h = π × (d/2)² × h = π × (1.35²) × 7.45 = 42.63374 in³

The following formula can be used to get the cylinder's surface area:

A = 2πr² + 2πrh = 2π × r² + 2π × r × h = 2π × (1.35²) + 2π × 1.35 × 7.45 = 45.1805 in²

The cylinder's weight can be determined using the formula below:

The solution to the equation 2x - 1/2 = 5 1/2 is x = 3.

Given Equation: 2x - 1/2 = 5 1/2

Step 1: Let's simplify the mixed number 5 1/2 to an improper fraction. 5 1/2 can be written as (11/2).

2x - 1/2 = 11/2

Step 2: To eliminate the fraction, multiply the entire equation by 2 to clear the denominators:

2  (2x - 1/2) = 2 (11/2)

This simplifies to:

4x - 1 = 11

Step 3: Add 1 to both sides of the equation to isolate the variable:

4x - 1 + 1 = 11 + 1

4x = 12

When adding a whole number and a fraction, the final result must still be a mixed number, with the whole number part representing the sum of the whole numbers and the fraction part representing the sum of the fractions.

In this case, adding 3 and 3/5 does not result in 6 and 3/5. To see this, we need to simplify the fractional part.

Two functions are inverses if their composition is equal to the identity, then if f(x) is the inverse of our function, we must have that:

g( f(x) ) = x

Here we know that:

g(x) = (x - 3)^(3/2) + 2

Evaluating this in f(x) we should get:

g( f(x) = (f(x) - 3)^(3/2) + 2  = x

Now we can solve that for f(x).

(f(x) - 3)^(3/2) + 2  = x
