The surface area of the square pyramid is given by S = 16 inches²

The total surface area is the summation of the areas of the base and the three other sides. A = B + ( 1/2 ) ( P x h ), where B is the area of the base of the pyramid, P is the perimeter of the base, and h is the slant height of the pyramid

Surface Area of Pyramid = B + ( 1/2 ) ( P x h )

Given data ,

Let the surface area of the square pyramid be S

Now , the equation will be

The surface area of the square pyramid = surface area of square + 4 ( area of triangles )

And , the side length of square a = 2 inches

So , the area of square = a² = 4 inches²

The height of the triangle h = 3 inches

The base of the triangle = a = 2 inches

So , the area of the triangle = ( 1/2 ) x a x h

On simplifying the equation , we get

The area of the triangle = ( 1/2 ) x 2 x 3 = 3 inches²

So , the area of 4 triangles = 4 x 3 = 12 inches²

Now , The surface area of the square pyramid S = 4 inches² + 12 inches²

On simplifying the equation , we get

The surface area of the square pyramid S = 16 inches²

Hence , the surface area of pyramid is 16 inches²

Conjecture: The quotient of two integers with a different sign will always be negative.

Example: -6 / 2 = -3 (negative)

Test: -8 / 4 = -2 (negative)

Step-by-step explanation:

61 percent of the 8th graders estimated they spend less than an hour a day on social media.

To find the percentage of 8th graders who estimated they spend less than an hour a day on social media, we need to calculate the proportion of 8th graders who answered "less" and then convert it to a percentage.

There were 12 + 19 = 31 8th graders in the sample.

Out of these 31 8th graders, 19 answered "less" and 12 answered "more".

So, the proportion of 8th graders who answered "less" is 19/31 = 0.61290323.

To convert this proportion to a percentage, multiply it by 100:

0.61290323 * 100 = 61.290323 (rounded to 2 decimal places).

Finally, rounding to the nearest whole number percent, we get:

61.290323 rounded to the nearest whole number percent = 61%

Therefore, 61% of the 8th graders estimated they spend less than an hour a day on social media.

the Sample variance is. [tex]$s^2[/tex]=41.4

Sample variance can be defined as the expectation of the squared difference of data points from the mean of the data set. It is an absolute measure of dispersion and is used to check the deviation of data points with respect to the data's average.

Sample variance is used to measure the spread of the data points in a given data set around the mean. All observations of a group are known as the population. When the number of observations start increasing it becomes difficult to calculate the variance of the population. In such a situation, a certain number of observations are picked out that can be used to describe the entire group. This specific set of observations form a sample and the variance so calculated is the sample variance.

The correct option is B. So 3.898989.. is a irrational number.

In mathematics, all real numbers that are not rational are referred to as irrational numbers (from the in- prefix assimilate to ir- (negative prefix, privative) + rational). In other words, it is impossible to describe an irrational number as the ratio of two integers. When there is an irrational relationship between the lengths of two line segments, the line segments are also said to be incommensurable. This means that there is no length, no matter how short, that could be used to express the lengths of the two supplied segments as integer multiples of itself.

In short, an irrational number is a real number that cannot be expressed as a fraction or ratio of two integers. Examples of irrational numbers include pi (3.14159), the square root of 2 (1.41421356237...), and e (2.718281828459045...).

The function q(x)=4(0.5)^{x}+3 has the same end behavior as x approaches infinity as the function graphed here. Option C is the correct option.

What is a function?

A function from a set X to a set Y assigns exactly one element of Y to each element of X. The set X is known as the function's domain, and the set Y is known as the function's codomain. Originally, functions were the idealization of how a varying quantity depends on another quantity.

Given graph function tends to a constant (a positive constant) when x tends to infinity.

Option A:

m(x) = -(0.3)^x - 3. The sign of -(0.3)^x is negative. Thus when x tends to infinity then m(x) tends to be a negative number.

Option B:

p(x) = -2(2)^x + 3. The sign of -2(2)^x is negative. Thus when x tends to infinity then p(x) tends to be a negative number.

Option C:

q(x) = 4(0.5)^x + 3. The sign of 4(0.5)^x is positive. Thus when x tends to infinity then q(x) tends to be a positive number.

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

Salut/Hello!

Definition of a function: In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

To make it more simple imagine a empty box with 2 holes ( one at the top and the other at the bottom ) and you insert a ball in the top hole and it falls thru the bottom hole.
When the ball falls inside the box (function) thru the top hole it'll be called
"input ball". The inside of the box can be called "function box:"
So once the ball falls out of the box thru the bottom hole it'll be called "output box(ball)".

Example: (using the image)
1. In this diagram of a function we have the domain X = {A,B,C} and codomain Y = {1,2,3} and it's defined with the set of ordered pairs  {(A, 2), (B, 1), (C, 3)} and the set range is {A,B,C}

2. In this diagram of a function we have the domain A = {1,2,3} and codomain B = {X,Y,Z} and it's defined with the set of ordered pairs {(1, Y), (2, Y), (3, Z)} and the set range is {Y,Z}

3. In this diagram, representing the set of pairs {(1,D), (2,E), (2,F)} does not define a function because 2 is the first element in more than one ordered pair, but also because 3 is not the first element of any ordered pair.

The graph of an absolute function looks like a V-shaped graph with its vertex of the given function y = |x| - 2 at  (0,-2). From the table, we are going to determine the y-values by replacing the x-values with the equation to solve for the y-values.

Given that:

y = |x| - 2 = |-3| - 2 = 3 - 2 = 1

y = |x| - 2 = |-2| - 2 = 2 - 2 = 0

y = |x| - 2 = |-1| - 2 = 1 - 2 = -1

y = |x| - 2 = |0| - 2 = 0 - 2 = -2

y = |x| - 2 = |1| - 2 = 1 - 2 = -1

y = |x| - 2 = |2| - 2 = 2 - 2 = 0

y = |x| - 2 = |3| - 2 = 3 - 2 = 1

For each x-value, there is one y-value. The x-values represent the domain of the function while the y-value represents the range of the function.
