To find the volume of a pyramid we need to multiply the area of its base by the length of its height and divide it by by three. This is why we divide the pyramid so as to obtain the desired result.

Formula to calculate the volume is ,

1/3 ( base area x height )

The base of a square pyramid is a square and the area of a square is found by the formula , side x side .

In order to identify a square pyramid we check for its base . If the apex of the pyramid is perpendicular to the center of the square, then it is a right square pyramid.

Answer:

width = 8 inches

Step-by-step explanation:

⭐ What is the formula for the perimeter of a rectangle?

We are given that the length is 14 inches longer than the width, and the perimeter of the rectangle is 60 inches.

So, let's substitute these values into the perimeter formula and solve for the width. Let w = width.

[tex]60 = 2(14 + w) + 2(w)[/tex]  Multiply the 2 into the parentheses

[tex]60 = 28 + 2w + 2w[/tex]       Add like terms (terms with the same variable)

[tex]60 = 28 + 4w[/tex]                Subtract 28 on both sides

[tex]32 = 4w[/tex]                        Divide both sides by 4 to isolate the variable

[tex]8 = w[/tex]

∴ The width is 8 inches.

A triangle's base and height are perpendicular to one other. In the same manner, if we know the triangle's area and height, we can calculate the triangle's base; conversely, if we know the triangle's area and base, we can calculate the triangle's height.

A triangle's height is always one of the triangle's sides. Drawn at an acute angle to the base must be a height that matches to the base. It is necessary to draw a height at a right angle to the base that matches to the base. Once we select a base, the associated height is represented by just one section.

What is probabilities?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.

An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes.

Statistics is the study of events that follow a probability distribution.

Answer:0

Step-by-step explanation:y=1/2x

straight lines are of the y=mx+c

The c value is where the graph cuts the y axis or the y intercept

as there is no value there c=0

or y intercept =0

4x+5y=20 in slope intercept form would be y= (-4/5)x + 4.

What do you mean by slope?

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

4x + 5y = -20

-4x            -4x

5y = -4x - 20

divide it all by 5

y = -4/5x - 4

Slope intercept form is y=mx+b. So you would first subtract 4x from both sides. This ends up being 5y= -4x +20. Then divide both sides by 5. This gets you y= (-4/5)x +4.

The number of units x that produces a maximum revenue with the expression given is x = 0.

To find the value of x that maximizes the revenue function R, we can take the derivative of R with respect to x and set it equal to 0. This will give us the critical point of the function.

The derivative of the function R with respect to x is:

R'(x) = 342x - 0.18x²

Setting this equal to 0, we get:

342x - 0.18x² = 0

Solving for x, we find that x = 0 or x = 1900.

However, we need to consider the constraints of the problem to determine which value of x is the optimal solution. If x is a number of units, then x cannot be negative. Therefore, the only valid solution is x = 0.

The square has a 48 centimeter perimeter.

To find the perimeter of the square, we need to calculate its side length. The area of a rectangle is given by its length multiplied by its width, so we can use the given measurements of the rectangle to calculate its area: 25 cm x 16 cm = 400 cm². The area of a square is given by the square of its side length, so we can use the area of the rectangle to calculate the side length of the square: √400 cm² = 20 cm.

Thus, the perimeter of the square is equal to 4 times its side length, or 4 x 20 cm = 80 cm.

A sampling distribution is a probability distribution of a statistic obtained from a larger number of samples drawn from a specific population. The sampling distribution of a given population is the distribution of frequencies of a range of different outcomes that could possibly occur for a statistic of a population.

Using the sample mean and the provided sample size, We can find the sample standard deviation by using the formula  [tex]\sqrt \frac {\sum {(x-\bar x)^{2}}}{n-1}[/tex] .

Sampling is the process of choosing a portion of a statistical population to estimate attributes of the entire population in statistics, quality control, and survey methods. Statisticians try to get samples that are typical of the population under consideration.

The arithmetic mean, also known as the arithmetic average or simply the mean or average, is the sum of a set of numbers divided by the total number of numbers in the set. The collection frequently consists of a series of findings from a survey, experiment, or observational study.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.
