The measure of variability that should never be used alone to reach conclusions regarding the variance of a distribution is the range.

The range only considers the difference between the maximum and minimum values in a dataset and does not take into account the distribution or dispersion of the data between these extreme values. Therefore, relying solely on the range to assess variance would not provide a comprehensive understanding of the distribution's spread and may lead to misleading conclusions.

It is recommended to use other measures of variability, such as standard deviation or interquartile range, in conjunction with the range to gain a more accurate representation of the variance.

The measurement of the angle OP is 39

The given parameters that will help us to answer the question are

R is mid point of OQ

S is mid point of PQ

RS = 3x + 38

OP = 4x- 14

R is mid point of OQ and S is mid point of PQ;

By using mid point theorem

[1/2][OP] = RS

This implies that So,

[1/2][3x + 38] = [4x- 14]

[3x+38] = 2[4x- 14]

Opening the brackets we have

3x+38=8x-28

Collecting like terms

3x-8x=-28-38

-5x=-66

Making x the subject of the relation we have

x = -66 / -5

x = 13.2

Therefore RS = 3(13.2) + 38 = -11.4

OP = 4(13.2)- 14=38.8

The two statements that are true about the company's Market share going from 50 to 65 percent of the total market . The initial market share and multiply by 100, which gives 30 percent. Option B is correct answer.

The two statements that are true about the company's market share going from 50 to 65 percent of the total market are:

The company's market share increased by 30 percent: The difference between the initial market share of 50 percent and the final market share of 65 percent is 15 percentage points. To calculate the percentage increase, we can divide the difference by the initial market share and multiply by 100, which gives (15/50) x 100 = 30 percent.

The company's relative market position improved: With a market share of 65 percent, the company now holds a greater proportion of the total market than before. This means that its relative market position has improved compared to its competitors, who have a smaller share of the market. This could translate into increased bargaining power, profitability, and other benefits for the company.

The variance of a random variable X, denoted as V(X), is a measure of the spread of the values of X around its mean. If you want to calculate V(X) and V(X-13), the variances will be different.

The variance of a random variable X, V(X), is calculated by subtracting the mean of X from each of the values of X, squaring each result, and then taking the average of these squares. This can be represented as V(X)=E[(X-μ)2].

The variance of X-13, V(X-13), is calculated by subtracting the mean of X-13 from each of the values of X-13, squaring each result, and then taking the average of these squares. This can be represented as V(X-13)=E[(X-13-μ)2].

Since the mean of X is not necessarily the same as the mean of X-13, it is clear that the two variances, V(X) and V(X-13), will be different.

Step-by-step explanation:

Note that the area and perimeter of the shape with the above given coordinates are:

Area: 70 square units
Perimeter: 34 units.

To find the area and perimeter of the rectangle with the given vertices, we can use the distance formula to find the length and width of the rectangle, and then use these values to calculate the area and perimeter.

First, let's label the vertices of the rectangle as follows:

A = (-3, 3)

B = (-3, -7)

C = (4, -7)

D = (4, 3)

To find the length of the rectangle, we can use the distance formula to find the distance between points A and B (which are on the same vertical line) and between points C and D (which are also on the same vertical line):

AB = |3 - (-7)| = 10

CD = |3 - (-7)| = 10

So the length of the rectangle is 10.

To find the width of the rectangle, we can use the distance formula to find the distance between points A and D (which are on the same horizontal line) and between points B and C (which are also on the same horizontal line):

AD = |4 - (-3)| = 7

BC = |4 - (-3)| = 7

So the width of the rectangle is 7.

Therefore, the area of the rectangle is:

A = length x width = 10 x 7 = 70

And the perimeter of the rectangle is:

P = 2(length + width) = 2(10 + 7) = 34

So the area of the rectangle is 70 square units and the perimeter of the rectangle is 34 units. See the attached graph.

Answer:

  the conclusion is not justified. No statement is made regarding the angles of the rhombus

Step-by-step explanation:

A square is a rectangle because of its right angles, not because of its equal-length sides. The rhombus having equal-length sides does not qualify it as a rectangle. The conclusion of the argument is unsupported.

The lengths of the missing sides are: y = 7.0 * sqrt(2) and x = 7.0 * sqrt(2)

Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees.

According to the 45-45-90 triangle theorem, the two legs of a 45-45-90 triangle are congruent and the hypotenuse is the square root of 2 times the length of the legs. Therefore, if the side opposite the 45-degree angle is 7, then the other leg is also 7.

Let's label the hypotenuse as h. We know that h is the side opposite the right angle, so h = x. Using the Pythagorean theorem, we can find the length of x:

\(x^2 = 7^2 + 7^2x^2 = 98x = sqrt(98) = 7.0 * sqrt(2)\)

So the length of the hypotenuse is 7.0 * sqrt(2).

Now let's find the length of the side opposite the other 45-degree angle, which we'll label as y. Since the two legs are congruent, y is also equal to 7.0 * sqrt(2).

Therefore, the lengths of the missing sides are: y = 7.0 * sqrt(2) and x = 7.0 * sqrt(2)

The volume of the cone is approximately 37.7 cubic units

What is volume?

A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder, or a sphere. Different shapes have different volumes.

To find the volume of a cone, we use the formula:

V = (1/3) * π * r² * h

where π is the constant pi, r is the radius of the base of the cone, and h is the height of the cone.

Plugging in the given values, we get:

V = (1/3) * 3.14 * 3² * 4 ≈ 37.7

The portfolio weights for stock A and stock B are approximately 55.69% and 44.31%, respectively.

To calculate the portfolio weights for stock A and stock B, we need to determine the total value of the portfolio and the proportion of each stock's value within that total.

The total value of the portfolio can be calculated as follows:

Total value = (Number of shares of stock A × Price per share of stock A) + (Number of shares of stock B × Price per share of stock B)

Total value = (135 × $84) + (110 × $82)

Total value = $11,340 + $9,020

Total value = $20,360

Now, we can calculate the portfolio weights for each stock:

Weight of stock A = (Value of stock A ÷ Total value) × 100%

Weight of stock A = (($84 × 135) ÷ $20,360) × 100%

Weight of stock A = $11,340 ÷ $20,360

Weight of stock A ≈ 0.5569 or 55.69%

Weight of stock B = (Value of stock B ÷ Total value) × 100%

Weight of stock B = (($82 × 110) ÷ $20,360) × 100%

Weight of stock B = $9,020 ÷ $20,360

Weight of stock B ≈ 0.4431 or 44.31%

Therefore, the portfolio weights for stock A and stock B are approximately 55.69% and 44.31%, respectively.

After answering the presented question, we can conclude that The equation number of trials is predetermined: We're going to roll the dice 20 times.

An equation is a statement in mathematics that shows that two expressions are equal. It consists of two sides separated by an equal sign (=). For example, 2 + 3 = 5 is an equation because the expression on the left-hand side (2 + 3) is equal to the expression on the right-hand side (5).

Equations are used in many areas of mathematics, science, and engineering to describe relationships between quantities and to solve problems. For example, equations are used to model physical phenomena, such as the motion of objects, the behavior of fluids, and the propagation of waves. They are also used in finance, statistics, and many other fields to analyze data and make predictions.

In this case, the random variable X reflects the number of times a specific number appears after rolling a 20-sided die 20 times.

To see if this situation fits the binomial distribution model, we must look at the four conditions listed below:

The trials are impartial: Each throw of the dice is distinct from the others.

There are just two possibilities: Each roll can produce one of the 20 numbers or none at all.

The likelihood of success is constant: The probability of rolling a given number on a 20-sided dice is the same for each roll.
