Yes, the Figure B is a scale copy of Figure A.
Given that are two figures we need to see if the Figure B a scale copy of Figure A or not.
To determine if Figure B is a scale copy of Figure A, we need to compare the two figures and check if they have the same shape but differ in size. A scale copy means that Figure B is an enlarged or reduced version of Figure A, but the proportions and shape of the two figures remain the same.
We see the side lengths of Figure A are: 6 units, 3 units, 3 units, 3 units, 6 units.
And that of Figure B are: 2 units, 1 unit, 1 unit, 1 unit, 2 units.
Taking the ratio = 6/2 = 3/1 = 3/1 = 3/1 = 6/2 = 3
So, it is clear that the side lengths are in equal proportion.
Hence the Figure B is a scale copy of Figure A.

A square has four right angles.
A right angle is a 90⁰ angle.
The diagonals divide each 90⁰ angle by 2
I hope you know what a diagonal is.
It is a line from a corner of the square to the opposite corner. This cuts the square into two equal sides.
After drawing the first diagonal two triangles of equal size will be seen.
After drawing the second diagonal the two triangles that appeared will each be cut into halves.
Now, you'll have four equal triangles.

Answers
Answer:
0.833
Step-by-step explanation:
1. locate which vertical column of the graph we are referring to:
student 72. calculate the total number of trials student 7 did:
if in 5 trials the tack landed point-up, and in 1 trial the tack did not land point-up, the total number of trials is 65 + 1 = 63. refer back to the question:
the question states: "what is the experimental probability that the tack lands point-up"4. interpret the graph:
of the 6 trials student 7 underwent, the graph tells us that 5 landed point-up. therefore the experimental probability of a tack landing point up is 5/6 (in 5 out of the 6 trials, the tack landed point-up)5. converting from fraction to decimal:
all the given answers are given in decimal form, whilst our current answer (5/6) is in fraction form. to convert to decimal form, simply divide the top number by the bottom number5 ÷ 6 = 0.833therefore, the experimental probability that the tack will land point-up, is 0.833

This expression involves the distributive property. In the distributive property, there is a number followed by an equation in parenthesis.

To simplify it, you have to multiply the first number by each number in the parenthesis, separately:
3(n+6)
3n + 3(6) or 3xn + 3x6 (same thing)
3n+18
Finally, we can check the other 4 choices to double check.
A. 3n+6 (wrong)

2xn + 2x6 + n + 6
2n + 12 + n + 6

2n+n + 12+6

Answers
Answer:
Step-by-step explanation:
n(U)=100%
n(S)=70%
n(W)=15%
n(S union w compliment)=20%
n(s intersection W)=?
n(u)=n(s)+ n(w)+ n(s union w compliment)- n(s intersection w)
or 100%=70% +15%+ 20% - n( s intersection w)
or 100%= 95%- n(s intersection w)
or 100%-95%=n(s intersection w)
or 5%= n( s intersection w)
now;
n(only w)=n(w)- n(s intersection w)
=15%- 5%
=10%
10%of people only like winter season.
i think the question is to find people who only like winter season.
if not then ans is 15% according to question.
a) The illustration of the given information in a Venn diagram is attached.
b) The percentage of people who liked both seasons is 45%.
c) If 180 people liked the summer season only, proportionately, the number of people who liked the winter season only is 300.
How the Venn diagram is illustrated:The Venn diagram, which shows similarities and contrasts, can be illustrated based on the given percentages.
Percentages are one of the ways to depict proportions, which are the equation of two ratios.
The percentage of survey people who liked the summer season = 60%
The percentage of survey people who liked the winter season = 70%
The percentage of survey people who liked none of the seasons = 15%
The percentage of participants who liked one of the seasons = 85% (100% - 15%)
The total percentage of survey people who liked either summer or winter = 130% (60% + 70%)
b) The percentage of survey people who liked both seasons = 45% (130% - 85%)
The percentage that liked only summer = 15% (60% - 45%)
The percentage that liked only winter = 25% (70% - 45%)
c) 180 people liked summer only
180 = 15%
Proportionately, if 180 = 15% of the people, the total number of people = 1,200 (180/15%)
The number of people who liked winter season only = 300 (1,200 x 25%)

How are the pieces of a step function related to the domain of the function? Justify your thinking.
Answers
Step-by-step explanation:
As we know, for any function domain is referred to as the set of input values that can be taken for an independent variable in the given function. Range of a function is defined as the set of output values generated for the domain (input values) of the function. In the case of a step function, for each value of x, f(x) takes the value of the greatest integer, less than or equal to x. For example:
[-2.19] = -3
[3.67] = 3
[-0.83] = -1
The domain of this function is a group of real numbers that are divided into intervals such as [-5, 3), [-4, 2), [-3, 1), [-2, 0) and so on. This explains the domain and range relations of a step function.
This can be generalized as given below:
[x] = -2, -2 ≤ x < -1
[x] = -1, -1 ≤ x < 0
[x] = 0, 0 ≤ x < 1
[x] = 1, 1 ≤ x < 2
For example:
1-2.191 =-3
13.671 = 3
[-0.831 = -1
The domain of this function is a group of real numbers that are divided into intervals such as [-5, 3), [-4, 2), [-3, 1), [-2, 0) and so on.
This explains the domain and range relations of a step function.

For this option, you will work individually.
Part 1: Collect Data
In order to complete your assignment, you will need to collect some data.
The first five data points have been provided for you.
Age
(years) Number of U.S. States Named in 60 Seconds
5 7
15 42
25 49
35 35
65 50
Take a survey of at least five more people. You need a watch, stopwatch, or timer.
First, record the age of the person you are surveying.
Next, ask the person to name as many U.S. states as possible in 60 seconds. Keep a count, and watch your timer. Record each person’s data next to his or her age.
Repeat this with at least five people, and be sure to survey a range of ages, from young to old.
Part 2: Organize Your Data
Create a table of values using the age and number of U.S. states named in 60 seconds.
A graph is provided with the first five points plotted. Use your table to add your five data points to the scatter plot.
You may create a new graph from scratch, containing all 10 points, print the sample graph and add your data, or save the sample as an image and use a drawing program to add your data to the image. If you choose to print and draw by hand, you need to be able to scan and upload your work at the end of the project.
A coordinate plane is shown. The x axis is labeled age in years and the y axis is labeled number of U.S. States named in 60 seconds. Five data points are already plotted on the graph. These points are located at 5 comma 7, 15 comma 42, 25 comma 49, 35 comma 35, and 65 comma 50.
Draw a line of best fit through your scatter plot. Draw by hand on your printed graph or use a drawing program on your computer to create the line.
Part 3: Drawing Conclusions
How did you decide where to place your line of best fit? Describe your reasoning.
Based on your data, describe the relationship between age and the number of U.S. states a person can name in 60 seconds.
Do you see any areas in your data or points that could be considered clusters or outliers? Explain your answer in complete sentences.
