The correct statement regarding the best measure of the variability is given as follows:

The IQR is the best measure of variability, and it equals 6.

The Interquartile Range (IQR) of a data-set represents the difference between the third quartile and the first quartile of the data-set.

As it is not affected by outliers, it is the best measure of variability of a data-set.

The quartiles for this problem are given as follows:

Hence the IQR is obtained as follows:

IQR = 21 - 15

IQR = 6.

The simplest form of (m². m⁵. m⁻³ ) is m⁴  

Writing a number as the product of itself a number of times are known as an Exponent.

For example,

If 7 is multiplied by itself 3 times, i.e. 7 × 7 × 7. This can be represented as 7³. Where 7 is the base and 3 is the exponent.

If a is multiplied by itself b times, i.e. a × a × a...(b times). This can be represented as (aᵇ). Where 'a' is the base and 'b' is the exponent.

Here we have

The expression (m². m⁵. m⁻³ )

As we know, (aᵇ . aˣ. aᵃ) = aᵇ⁺ˣ⁺ᵃ  

(m². m⁵. m⁻³ ) = m²⁺⁵⁻³  = m⁴  

Therefore,

The required orders are Kara served 12.5 orders, Harry served 22.5 orders, and Erin served 50 orders.

An equation that holds true for one or more values of the variable but holds false for other values of the variable is known as a conditional equation. In Hannah's example, the equation holds true for the value of x equal to 10, but not for other values, such as 1. The equation is a conditional equation as a result.

Let we consider the number of orders Kara served as x.

Then, Harry served x + 10 orders and Erin served 4x orders.

The total number of orders they served is x + x + 10 + 4x = 86 orders.

So, 6x + 10 = 86

6x = 76

x = 12.5

Kara served 12.5 orders, Harry served 22.5 orders, and Erin served 50 orders.

Answer:

Step-by-step explanation:

Let the orders served by Kira be k.

Orders served by Henry= 10 less than Kira

                                       = k-10

Orders served by Erin= 4 times of Kira

                                   = 4k

Total orders served= 86

     Kira+Henry+Erin= 86

               k+k-10+4k= 86

                       6k-10= 86

                            6k= 86+10

                            6k= 96

                              k= 96/6

                              k= 16

Kira= k= 16

Henry= k-10= 16-10= 6

Erin= 4k= 4x16= 64

∴ Kira served 16 orders, Henry served 6 orders & Erin served 64 orders

They both represent the same information - for every 96 action/ adventure movies, there are 38 sci-fi movies to stream.  96:38 and 38:96 are both equivalent ratios because they are inverse proportions of each other.

Inverse is the opposite of something. It can be used to describe the opposite of a mathematical operation, such as taking the reciprocal of a number, or the opposite of a logical statement, such as negating the statement. It can also be used to describe the opposite of an action, such as reversing a direction or undoing an action. Inverse can also be used to describe the opposite of an effect, such as the opposite of a physical reaction or the opposite of an emotional response. Inverse relationships can often be seen in nature, such as how a decrease in temperature results in an increase in pressure, or how an increase in the amount of light results in a decrease in the number of insects in a certain area.

Answer:

To determine how many cakes Jahnay is making, we need to calculate the total weight of the ingredients for one cake and then divide the total amount of flour Jahnay is using by that amount.

First, let's calculate the total weight of ingredients for one cake:

150 g sugar + 120 g butter + 210 g flour + 2 eggs = 480 g

Next, let's divide the total amount of flour Jahnay is using by the total weight of ingredients for one cake:

840 g / 480 g = 1.75 cakes

So Jahnay is making 1.75 cakes.

The relationship between the rectangles ABCD and WXYZ is AB = WX.

The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.

Given the rectangles ABCD and WXYZ, in a coordinate grid,

length of rectangle ABCD is parallel to the Y-axis and the length of rectangle WXYZ is parallel to the X-axis,

let us consider the scale of the grid to be 1 unit,

from graph,

AD = BC = 5 units

AB = DC = 3 units,

and for rectangle WXYZ,

XY = WZ = 5 units

WX = YZ = 3 units

The value of the coefficients a, b, c, and constant d will be 0.50, 0, -1.50, and 1, respectively.

Let a, b, c, and d are the zeroes of the polynomial and k be the leading corefficient. Then the polynomial is given as,

⇒ k(x - a)(x - b)(x - c)(x - d)

The degree of the polynomial will be greater than or equal to the number of zeroes.

From the graph, the zeroes are -2, 1, and 1. Then the polynomial is given as,

y = a(x + 2)(x − 1)²

The curve passes through (0, 1), then we have

1 = a(0 + 2)(0 − 1)²

1 = 2a

a = 1/2

a = 0.5

Then the polynomial is given as,

y = 0.50 (x + 2)(x − 1)²

y = 0.50 (x + 2)(x² + 1 - 2x)

y = 0.50 (x³ + 2x² + x + 2 - 2x² - 4x)

y = 0.50 (x³ - 3x + 2)

y = 0.50x³ - 1.5x + 1

The sphere ball will not sink because it has a density of 0.34 g/cm³ which is lesser than density of water

Density is the substance's mass per unit of volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume.

Density = mass/volume

volume of the sphere = 4/3 πr³

= 4/3 × 3.14 ×4³

= 803.84/3

= 267.95 cm³

Density of the sphere = 90/267.95

What is the angle bisector theorem?

The angle bisector theorem states that a triangle's angle divides the opposing side into two portions that are proportionate to one another.

We have given,

Triangle, Let's consider it ΔABC,

then,

Measures of Angles ∠B= 37, ∠C=32, and side AD = 82

To find x =?

In the triangle side AD is the bisector, it forms a new triangle  ΔADC.

According to the angle bisector theorem, the angle bisector of a triangle divides the opposite side into two parts that are proportional to the other two sides of the triangle.

As per the Angle bisector theorem, the ratio of the line segment BD to DC equals the ratio of the length of the side AB to AC.

To find AB & AC:

sin θ = side opposite to angle θ / hypotenuse

cos θ = side adjacent to angle θ / hypotenuse

sin θ = AD / AB

sin 37 = 82 / AB

AB = 82/ sin 37

AB = 136.25

cos θ = BD / AB

cos θ = BD/136.25

BD = cos37 * 136.25

BD = 104.9

sin θ = AD / AC

sin32 = 82 / AC

AC = 149

cos32 = DC / AC

cos32 = DC / 149

DC = 123.67

So, x = BD + DC

x = 104.9 + 123.67

x = 228.57

Hence, the value of the x is 228.57 units.

can give brainliest if this helps ;)

Answer:

1440

Step-by-step explanation:

We should first count the chair and vice-chair as one unit i.e. one person since they have to be seated together

This means there are 6 items effectively and these 6 items can be arranged in 6! ways

6! = 720 ways

But there is more....

The chair and vice-chair have to sit together but they can sit together in two different ways:
Chair can be on the left, vice-chair can be on the right

or

Chair can be on the right,  vice-chair can be on the left

So for each of the 6! combinations there are 2 ways of seating the chair and vice-chair together

Total number of ways = 6! x 2

= 720 x 2 = 1440
