Explain why the question "How many colors are there in the United States flag?" is NOT a statistical question.a) There are very few possible answers.
b) The answer may change over time.
c) The variability in the data is limited.
d) There is no variability in the answers.

Answers

Answer 1
Answer: Answer=D

The number of colors on the US flag is a question with only one correct answer. There is no variability in the answers.

a and c are incorrect because there is only ONE correct answer to the question.

b is incorrect because the information possibly changing overtime doesn't effect the validity of it being a statistical answer or not.

Answers

Hi!

(2)/(3)=(x)/(12)

(x)/(12)=(2)/(3)

(12x)/(12)=(2*12)/(3)

(12x)/(12)=x

(2*12)/(3)=8

Answer---->x=8

Explanation: First you had to switch sides to the problem. Then multiply by 12 from both sides. And simplify by 12x/12=8 or 2*12/3=8. And the answer should be x=8 is the right answer. Hope this helps! Thank you for posting your question at here on Brainly. And have a great day. -Charlie
8 is the answer to your question.

In golf, scores are often written in a relationship to par, the average score for a round at a certain course. Write an integer to represent a score that is 7 under par.

Answers

Because the situation represents under par, the integer is –7. So its -7
I think the correct answer is -7 hope this helps

Hot dogs buns come in packages of 8 for the school picnic mr spencer bought 30 packages of hot dog buns . How many hot dog buns did he buy

Answers

Answer:

240 buns

Step-by-step explanation:

Hot dogs buns come in packages of 8.

Mr Spencer bought 30 packages of hot dog buns for the school picnic.

We have to multiply 30 packages with number of buns in one package.

He bought total number of hot dog buns = 30 × 8

                                                                    = 240 buns

Mr. Spencer bought 240 hot dog buns.
He bought 240 hot dog bun for the picnic you need to multiply 30x8=240

PLEASE HELP I GIVE THANKS

Answers

Let's say 'x' to the unknown length, since the sides are proportional we can build up a equation like this : \frac { 11 }{ 8 } =\frac { x }{ 12 } \n 11\cdot 12=8x\n 132=8x\n \frac { 132 }{ 8 } =x\n x=16.5 
The answer is A.

Solve 5r2 – 12 = 68. {±4} {±5} {±3} {±6}

Answers

we are given

5r^2-12=68

Since, we have to solve for r

so, firstly we will isolate r terms

so, we will move 12 on right side

we can add both sides by 12

5r^2-12+12=68+12

5r^2=80

now, we can divide both sides by 5

(5r^2)/(5) =(80)/(5)

r^2=16

now, we can take sqrt both sides

and we get

r=4 , r=-4

so,

Think about making a factor rainbow for drawing rectangles to list all the factors of a number. how are the two methods alike? how are they different? ( pls tell me the answer)​

Answers

Answer:

HOPE IT HELPS! PLS mark branliest

Step-by-step explanation:

Creating a "factor rainbow" and listing the factors of a number by drawing rectangles are two visual methods used to understand and identify the factors of a given number.

Similarities:

Visual Representation: Both methods rely on visual aids to help understand and identify factors.

Systematic Approach: They both provide a structured way to identify factors. They guide you through a process to ensure you don't miss any factors.

Differences:

Nature of Representation:

Factor Rainbow:

A factor rainbow is typically a circular or semi-circular diagram. The number is placed at the top, and its factors are shown as radii (lines from the center to the edge) of the circle.

Each factor is represented as an arc.

It's a visual representation that helps to see the pairs of factors and how they relate to each other.

Rectangles:

Drawing rectangles involves creating a rectangular grid or array, with the number of rows and columns corresponding to the potential factors.

Each rectangle represents a possible combination of factors, and the number of rectangles gives a visual representation of how many factors there are.

It's a more structured and organized representation.

Space Utilization:

Factor Rainbow:

It might be more space-efficient compared to drawing rectangles because it uses a circular or semi-circular layout.

Rectangles:

Depending on the size of the number and the number of factors, drawing rectangles can require a larger space as it involves creating a grid.

Ease of Identification:

Factor Rainbow:

It's useful for visualizing relationships between factors. It's good for understanding how factors pair up.

However, it may not be as straightforward for identifying all factors, especially for larger numbers.

Rectangles:

It provides a systematic method for identifying all factors. You can easily count the number of rectangles to find the total number of factors.

Flexibility for Visualization:

Factor Rainbow:

It can be a bit more flexible in terms of visualization as it allows for curvature in its representation.

Rectangles:

It's a very structured method, which may not lend itself to certain numbers as well (e.g., prime numbers).

In summary, both methods serve the purpose of visualizing factors, but they do so in different ways. The factor rainbow emphasizes relationships between factors, while drawing rectangles provides a structured method for systematically identifying all factors. The choice of method may depend on personal preference and the specific number being analyzed.

Answer:

Both the factor rainbow and drawing rectangles are methods used to visually list all the factors of a given number.

Similarities:

Visual Representation: Both methods provide a visual representation of the factors of a number, making it easier to understand and identify the factors.

Systematic Organization: Both methods organize the factors in a systematic way, allowing for a clear and organized display of the factors.

Differences:

Representation Style:

A factor rainbow is a simple visual representation where factors are listed in an arched shape, starting from 1 and extending to the given number.

Drawing rectangles involves creating a grid or rectangles to represent the factors, where the dimensions of the rectangles correspond to the pairs of factors.

Geometric vs. Linear:

Drawing rectangles uses a geometric representation (rectangles) to display the factors.

Factor rainbow is a linear representation, showcasing the factors in an arched arrangement.

Flexibility and Versatility:

Drawing rectangles allows for the demonstration of the commutative property of multiplication (e.g., for factors 6 and 10, you can create a rectangle with dimensions 6x10 or 10x6).

Factor rainbow is a simpler method and may not easily demonstrate the commutative property.

In summary, both methods serve the purpose of visually representing the factors of a number, but they use different styles and structures for this representation. Drawing rectangles involves a geometric approach, while the factor rainbow uses a linear arrangement. Drawing rectangles also offers additional versatility in illustrating the commutative property of multiplication.
