The term that best describes the analysis conducted by the researcher is "descriptive statistics".

What is Descriptive statistics?

A descriptive statistic is a summary statistic that quantitatively describes or summarizes features from a set of data, whereas descriptive statistics is the process of employing and analyzing those statistics.

The term that best describes the analysis conducted by the researcher is "descriptive statistics".

Descriptive statistics is the branch of statistics that deals with the summarization, presentation, and interpretation of data. In this case, the researcher recorded the height of all 217 adult members of a tribe and calculated the average height, which is a measure of central tendency. The purpose of this analysis was to describe the distribution of height among the tribe members, rather than to make inferences about the population or test hypotheses about the population parameters.

In summary, the researcher used descriptive statistics to describe the distribution of height among the tribe members by summarizing the data using measures such as the average height.

Answer:

Option A (You chose it right)

Step-by-step explanation:

Base of triangle = [tex](\frac{\sqrt{2}}{2} + \frac{\sqrt{2}}{2})[/tex] units

Since the two fractions have the same denominator, the resulting simplified fraction will have the same denominator and everything written in the numerator level will be copied down as it is:

                           = [tex]\frac{\sqrt{2} + \sqrt{2}}{2}[/tex]

                           =[tex]\frac{2\sqrt{2}}{2}[/tex]

                           = [tex]\sqrt{2}[/tex] units

Area:

Area of a triangle = [tex]\frac{1}{2}[/tex] × base of triangle × perpendicular height

                             = [tex]\frac{1}{2}[/tex] × ([tex]\sqrt{2}[/tex] units) × ([tex]\frac{\sqrt{3}}{2}[/tex] units)

                             = ([tex]\frac{\sqrt{2}}{2}[/tex] ×[tex]\frac{\sqrt{3}}{2}[/tex]) square units

     ∴ Area            [tex]= \frac{\sqrt{6}}{4}[/tex] square units

Perimeter:

It is the sum of all the outer sides (or outer boundaries) of the triangle:

Perimeter = Base of triangle + first slanted height + second slanted height

                = [tex](\sqrt{2} + \sqrt{2} + \sqrt{2})[/tex] units

                [tex]= 3\sqrt{2}[/tex] units

∴ Option A

Since triangle ABC with vertices at A(−3, −3), B(3, 3), C(0, 3) is dilated to create triangle A′B′C′ with vertices at A′(−15, −15), B′(15, 15), C′(0, 15), the scale factor used is: A. 5.

In Geometry, the scale factor of a geometric figure can be calculated by dividing the dimension of the image (new figure) by the dimension of the pre-image (original figure):

Scale factor = Dimension of image (new figure)/Dimension of pre-image(actual figure)

Substituting the given parameters into the scale factor formula, we have the following;

Scale factor = Dimension of image (new figure)/Dimension of pre-image(original figure)

No, it is not possible to have a connected graph with six vertices of degrees 1, 1, 2, 2, 2, and 3.

As we know that the sum of the degrees of the vertices in a connected graph must be equal to twice the number of edges.

So, in this case, the sum of the degrees must be equal to 2 * K, where K is the number of edges in the graph.

Since the degrees of the vertices are 1, 1, 2, 2, 2, and 3,

the sum of the degrees is 1 + 1 + 2 + 2 + 2 + 3 = 11.

The number of edges must be K = 11 / 2 = 5.5,

which is not possible as the number of edges must be a positive integer.

Therefore, it is not possible to have a connected graph with six vertices of degrees 1, 1, 2, 2, 2, and 3.

The plane is travelling at a speed of 424.26 mph.

Velocity of an object is the speed of the object with a given direction. Therefore velocity is a vector quantity and speed is a scalar quantity.

Given that,

A plane is traveling Northeast.

If the plane is travelling northeast, then the angle that the plane makes with the horizontal component will be 45°.

The eastern component of it's velocity is 300 mph.

Vector v can be represented as v cos (θ) i + v sin(θ) j.

Here v cos (θ) is the eastern component and v sin(θ) is the northern component.

v cos (θ) = 300

v cos(45°) = 300

v = 300 / cos(45°)

  = 300 / (1/√2)

  = 424.26 mph

Hence the speed of the plane is 424.26 mph.

Therefore, the new triangle XYZ with vertices X'(-8,3), Y'(-1,2) and Z'(-2,-7) is obtained after the transformation.

Triangles are called polygons if they have four quadrants or more. Its form is a simple geometric figure. When put together, the characters ABC create a right-angled triangle. When the boundaries are incompatible, Euclidean geometry generates a new rectangle with square corners. Triangles are regarded as polygons because they have three edges and three corners. Where a triangle's three edges intersect determines where its corners are. A triangle's interior sides add up to 180 degrees.

Here,

After the transformation, the new vertices of the triangle will be:

X(1-9, 8-5) = (-8,3)

Y(8-9, 7-5) = (-1,2)

Z(7-9, -2-5) = (-2,-7)

Answer:

-3(x+0.5)^2-181/4 (if I calculated correctly)

Step-by-step explanation:

f(x)=-3x^2-3x-46

=-3(x^2+x+46/3)

=-3(x+0.5)^2-(0.5)^2+46/3

=-3(x+0.5)^2+181/12

=-3(x+0.5)^2-181/4

The chart fits the functional equation for all values of x, according to the claim made.

The Geometric Mean (GM) in mathematics is the average or mean that, by calculating the product of the values of the collection of numbers, denotes the central trend of the numbers. In essence, we combine the numbers collectively and calculate their nth root, in which n is the entire amount of data values.

We can use the given functional equation f(x+1) = 4(f(x)) to find the values of f(x) for each value of x, given that we know f(1) = 4. We start by computing:

f(2) = 4(f(1)) = 4(4) = 16

f(3) = 4(f(2)) = 4(16) = 64

f(4) = 4(f(3)) = 4(64) = 256

f(5) = 4(f(4)) = 4(256) = 1024

Now, we have determined all the values of f(x) for x=1 to 5. Since the table has 5 rows, we can write:

x f(x)

1 4

2 16

3 64

4 256

5 1024

We can check that the table satisfies the given functional equation f(x+1) = 4(f(x)). For example, when x = 3, we have:

f(x+1) = f(4) = 256

4(f(x)) = 4(f(3)) = 4(64) = 256

Answer: -13

Step-by-step explanation:

The principal amount of $5,000 deposited for 8 years with simple interest gives amount $7,880 at the annual interest of 7.2%.

Total amount 'A' in the Macy account after 8 years = $7,880

Time 't' = 8 years

Principal amount 'P' = $5,000

Let 'r' be the rate of interest given in saving account with annual simple interest.

Simple interest = Amount - Principal

                         = $7,880 - $5,000

                         = $2,880

Simple interest = ( P × r × t ) / 100

Substitute the value we get,

⇒ $2,880 = ( 5,000 × r × 8 ) / 100

⇒ r = ( 2,880 × 100 ) / ( 5,000 × 8 )

⇒ r = 7.2%

Therefore, the annual interest rate for the given amount as per simple interest is equal to 7.2%.

Rate of change is   slope  = rise / run =  (0 - -3) / (-3 - -2) = 3/-1 = -3

The equation of the parallel lines is y = x + 2.

Parallel lines are any two or more lines that all lie in the same plane and never cross one another. They are equally spaced apart and have the same incline. No matter how far we extend a parallel line, it will never meet another parallel line.

The slope of two parallel lines are equal.

The equation of the given line is:

y = x + 6

here, the slope of the line is 1.

So, the slope of the new line is 1.

The new line has the coordinates (-4, 1).

Using the point-slope form we have:

y - y1 = m (x - x1)

y - 1 = 1 (x + 1)

y - 1 = x + 1

y = x + 2

Hence, the equation of the parallel lines is y = x + 2.

This would be perpendicular

Lines that intersect to form right angles

As mentioned above this would be perpendicular

Parallel lines always have the same slope, so this goes for parallel.

Equations that can be written in slope intercept form

This would be both as all lines can be written in this form

Non vertical lines that have the same slope and different y-intercepts

As they have the same slope this would make it parallel

You can determine the relationship between two lines by comparing their slopes and y-intercepts.

A terrarium is a glass container with soil and plants inside of it that can be opened for maintenance purposes. Terraria, however, can be exposed to the atmosphere rather than being sealed. Terraria are usually kept as decorative or ornamental items.

The volume of Terrarium B is 2 m³, so its side length is the cube root of 2, which is approximately 1.26.

The side length of Terrarium A is 4 times that, or approximately 5.04. The volume of Terrarium A is [tex]2^x[/tex] cubic meters, so we can set up the equation:
