The expression for volume is (28-2x)(22-2x)x and when x=6, the volume is 840 inch^3.
What is volume?
A 3D object's volume is the amount of actual space it occupies. It is a 2D shape's 3D equivalent of area. It is quantified in cubic units like cm3. It means that the amount of space a closed form can occupy in three dimensions depends on its volume. Volume is a gauge of a thing's potential. For instance, a cup is said to have a 100 ml capacity if the brim can hold 100 ml of water. Another way to measure volume is the amount of space a three-dimensional item takes up.
According to question,
Let x be the height of the cubic box
Length = (28-2x)
Breadth = (22-2x)
Volume = x(28-x)(22-x)
When x =6
Volume = 6(28-6×2)(22-6×2)
=6(10)(14)
=840 inch^3

The probability P(5 ≤ x ≤ 9) is 0.6847
Assume that x has a normal distribution
We have been the mean and standard deviation μ = 6; σ = 2.
To calculate this probability we use the standardized normal distribution and the z-value for 5 and 9.
z = (5 - 6)/2
= -0.5
and z = (9 - 6)/2
= 1.5
Then the probability is calculated as:
P(x ≤ 5) = 0.3085
P(x ≤ 9) = 0.9932
P(5 ≤ x ≤ 9) = 0.9932 - 0.3085
P(5 ≤ x ≤ 9) = 0.6847
Therefore, the probability P(5 ≤ x ≤ 9) is 0.6847

All the dimensions of the shape is found as 19 ft.
What is termed as the perimeter?The perimeter of any closed shape is the total length of its boundary. The total length around a shape is described as its perimeter. It is the length of any two-dimensional spatial shape's outline or boundary. Depending on the dimensions, the perimeters of irregular shapes can indeed be equal in size.For the given question, the dimensions of the shape is given as;
(4x-5) ft(25-x) ft(13 + x) ft(3x+1) ftThe perimeter of the shape = 76 ft.
The formula of the perimeter = sum of length of all sides.
Let 'P' be the perimeter.
P = (4x-5) + (25-x) + (13 + x) + (3x+1) ing
Simplifying
P = 4x - x + x + 3x - 5 + 25 + 13 + 1
76 = 7x + 34
7x = 76 - 34
7x = 42
x = 6
Thus, the dimensions of the shape is; Put x = 6
(4×6-5) ft = 19 ft(25-6) ft = 19 ft(13 + 6) ft = 19 ft(3×6+1) ft = 19 ftThus, all the dimensions of the shape is found as 19 ft.

if the total value of the coins is $5.50 and kayleigh has 17 quarters, how many nickels does she have?
Kayleigh have 25 nickels with her.
Given,
The total value of coins Kayleigh have = $5.50
Number of quarters with Kayleigh = 17 quarters
We have to find the number of nickels Kayleigh with her.
Lets see:
1 dollar = 4 quarters
1 dollar = 20 nickels
Here, we have a total of 5.50 dollar
In this, 17 quarters are there.
So,
17 / 4 = 4.25
That is, the value of coins as quarters is $4.25
Now,
5.50 - 4.25 = 1.25
That is,
$1.25 is in the form of nickels.
Number of nickels = 1.25 × 20
Number of nickels = 25
Therefore,
Kayleigh have 25 nickels with her.

give an example of a rational function that has a horizontal asymptote at y=3
An example of a rational function is y = (3x²+7x+4)/(x²+3x+2) which has a horizontal asymptote at y = 3.
To give it a horizontal asymptote of y = 3, we require the degrees in the numerator and denominator to be and the lead coefficient ratio to be 1.
Yet, in producing the hole, we need to have the rest of the function, disregarding the (x + 1)'s, = 1 when x = -1 to ensure the y-value of the hole is at + 1. When we add all of this together, we get.
y = (3(x+1)(x+k))/((x+1)(x+2)) and the last condition requires k = + 4/3, so
By distributing the 3 in the numerator to the 2nd linear component, we get.
y = (3(x+1)(x+4/3))/((x+1)(x+2))
y = ((x+1)(3x+4))/((x+1)(x+2))
y = (3x²+7x+4)/(x²+3x+2)
Thus, the example of a rational function is y = (3x²+7x+4)/(x²+3x+2) which has a horizontal asymptote at y = 3.

pick a game of chance using cards or dice and a certain outcome in that game, (such as a large straight in yahtzee, or a four of a kind in poker). explain how many ways the outcome could happen and the total number of different hands or rolls there are in that game, and show the probability of your chosen outcome.
Yahtzee is a game of chance like dice or poker. The numbers of ways the outcomes ( straight rolling ) is 240 .
Probability of hitting a large straight is 240 / 7776 = 1/32
Yahtzee is the one of dice game that uses five standard six-sided dice. After rolling each die, the player can decide which die to keep and which to reroll. Goals include many different types of combinations, many of which originate from poker.
The two types of combinations that players must roll are called roads: small roads and large roads. Similar to poker straights, these combinations consist of consecutive dice. A small straight uses 4 out of the 5 dice and a large straight uses all 5 dice. Since the dice rolls are random, we can use probability to analyze the likelihood of hitting large straight on a single roll. Assumes that the dice used are fair and independent of each other. Now, you need to know how many ways you can roll a big/ large straight. Here it is more difficult than calculating the sample size. Big straights are harder to roll than small straights, but it’s easier to count the number of times you’ve rolled a big straight than the number of times you’ve rolled a small straight.
Next, determine the number of ways to get a straight by rolling the given dice. To get a nice straight with dice {1, 2, 3, 4, 5}, you can arrange the dice in any order. It turns out that you just swap the five dice. There are 5! = 120 ways to do this. There are two dice combinations that form the large Straight, each with 120 ways to roll, so there are 2 x 120 = 240 ways to roll the large Straight.
Now the probability of hitting a big/ large straight can be calculated with simple division. Since there are 240 ways to get the big straight in one roll, and 7776 rolls 5 dice, the odds of getting the big straight are 240/7776, close to 1/32, and lie 3.1%.

Work Shown:
[tex](f+g)(\text{x}) = f(\text{x})+g(\text{x})\\\\(f+g)(\text{x}) = (2\text{x}^2+\text{x}-11)+(\text{x}-1)\\\\(f+g)(\text{x}) = 2\text{x}^2+\text{x}-11+\text{x}-1\\\\(f+g)(\text{x}) = 2\text{x}^2+(\text{x}+\text{x})+(-11-1)\\\\(f+g)(\text{x}) = 2\text{x}^2+2\text{x}-12\\\\[/tex]
The domain of each f(x) and g(x) is "set of all real numbers" since we can replace x with any real number to get some output.
By extension, this means the domain of (f+g)(x) is also "set of all real numbers".
It turns out any polynomial will have this domain. We don't have to worry about things like applying square roots to negatives, or dividing by zero. This is why there isn't a restriction on x.
To write "set of all real numbers" in interval notation, we would say [tex](-\infty, \infty)[/tex] to indicate x is anything between negative infinity and positive infinity.

A pyramid has an isosceles triangle base with sides of 25,25 and 48 units.
The height of the pyramid is 30 units. The volume of the pyramid is 13What is the volume?We have a pyramid with four sides and a square base. Two-thirds of the pyramid's sides make up its height. The volume of a pyramid is 1, and we need to determine which of them matches our volume. Third, multiplying the length by the width gives us our base's area, which is s times s, or s square.This tells us that our base's height is equal to two-thirds of its side because it is a square base.
That makes it 2 to times s, or 2 s over 3. So we incorporate that into our equations next. We have a volume that is equal to 1/s squared / 2 / s spanning 3 points.Therefore, a pyramid has an isosceles triangle base with sides of 25,25, and 48 units.
