The first diagram shows the parallel lines cut by a transversal.
According to the statement
We have to explain all about the parallel lines cut by a transversal.
So, For this purpose, we know that the
A transversal line is a line that passes through two lines in the same plane at two distinct points.
And
Parallel lines are lines in a plane that are always the same distance apart.
From the given information:

The graph below shows the ages of the top five male finishers in the Mt. Washington Auto Road Bicycle Hillclimb each year from 2017 through 2021.
1. Write the relation of this situation as a set of ordered pairs in terms of (age, finishing place).
2. Identify the domain and range of the relation.
3. Do the ordered pairs represent a function? Explain.
From the given table, we have that:
1. The relation of the situation is: (20,2), (22.5, 5), (25,4), (27.5, 4), (29,4), (29,5), (30,1), (30,2), (30,3), (30,4), (30,5), (32.5, 1), (32.5, 3), (35,4), (40,2), (42.5, 3).
2. The domain is {20, 22.5, 25, 27.5, 29, 30, 32.5, 35, 40, 42.5} and the range is {1, 2, 3, 4, 5}.
3. There are inputs such as 25, 29, 30 and 32.5 that are mapped to multiple outputs, hence the relation does not represent a function.
What is the relation of this situation?
To build the relation, we look at the graph, and write all pairs of (Age, Finishing Place), as follows:
(20,2), (22.5, 5), (25,4), (27.5, 4), (29,4), (29,5), (30,1), (30,2), (30,3), (30,4), (30,5), (32.5, 1), (32.5, 3), (35,4), (40,2), (42.5, 3).
What are the domain and the range?The domain of a relation is the set that contains all possible input values for the values, that is, the values of x.The range of a relation is the set that contains all possible output values for the values, that is, the values of y.Hence, for the given relation:
The domain is {20, 22.5, 25, 27.5, 29, 30, 32.5, 35, 40, 42.5} and the range is {1, 2, 3, 4, 5}.
When does a relation represents a function?A relation represents a function if each value of the input is mapped to only one value of the output.
For this problem, we have that:
There are inputs such as 25, 29, 30 and 32.5 that are mapped to multiple outputs, hence the relation does not represent a function.

Find C that is 1/5 the distance from A(4, 2) to B(8, 7).
The coordinate of C that is 1/5 the distance from A(4, 2) to B(8, 7) is C(x,y) = {(44/6, (37/6)}
Midpoint of a lineThe formula for calculating the point on a line divided into ratio a:b is expressed as;
C(x,y) = {(ax₁+bx₂)/2, (ay₁+by₂)/2}
Given the following coordinate points A(4, 2) to B(8, 7) divided in the ratio 1:5 is expressed as:
C(x,y) = {(1(4)+5(8))/1+5, (1(2)+5(7))/1+5}
C(x,y) = {(44/6, (37/6)}
Hence the coordinate of C that is 1/5 the distance from A(4, 2) to B(8, 7) is C(x,y) = {(44/6, (37/6)}

Find The Slope of the Line?
Answer: 3
Step-by-step explanation:
To find the slope you have to divide y over x: y/x or most commonly known as rise/run.
We start at the point where the line is touching a point, in this case it's -8 in the y axis.
Then we count up until we find another point that the blue line is touching. In this case at the coordinates (2, -2). So there's 6 values up from -8 and we have to move to the right 2 values to reach the point the blue line is touching.
So we use the formula rise/run or y/x:
6/2 = 3

Find the population mean or sample mean as indicated. Sample: 16, 17, 5, 6, 16
Answer:
sample mean = 12
Step-by-step explanation:
To find the mean of a sample of items, we can use the following formula:
[tex]\boxed{\mathrm{mean = \frac{sum \ of \ items}{number \ of \ items}}}[/tex].
In this question, we are given the following items: 16, 17, 5, 6, and 16.
• sum of items = 16 + 17 + 5 + 6 + 16
= 60
• number of items = 5
∴ mean = [tex]\frac{60}{5}[/tex]
= 12
Therefore, the sample mean is 12.

A square array of numbers, often positive integers, is referred to as a magic square in recreational mathematics if the sums of the numbers in each row, each column, and both main diagonals are the same.
The following values are listed in the question:
The numbers are 4, 5, 6, 14, 15, 16, 24, 25, and 26.
A 3-by-3 magic square is required.
Since the numbers are 4, 5, 6, 14, 15, 16, 24, 25, and 26.
Now the sum of all numbers is :
4 + 5 + 6 + 14 + 15 + 16 + 24 + 25 + 26 = 135
There are now 3 rows and 3 columns, thus the total number is divided by 3.
5 24 16
26 15 4
14 6 25
5 + 24 + 16 = 45
5 + 26 + 14 = 45
26 + 15 + 4 = 45
24 + 15 + 16 = 45
14 + 6 + 25 = 45
5 + 15 + 25 = 45
So, the total of each row and each column is therefore 45.
Therefore, this is a 3-by-3 magic square that satisfies the conditions :

Find the error in the calculations below, if there is one:
Line (1): 8x4 = 2(4x + 1) -6
Line (2): 8x - 4 = 8x +1-6
Line (3): 8x - 4 = 8x - 5
Line (4): -4 = -5
Line (5): Based on the calculations above, there are no solutions.
O The error occurred from line (1) to line (2).
The error occurred from line (2) to line (3).
The error occurred from line (3) to line (4).
O The error is in line (5).
The error occurred from line (2) to line (3) i.e., option(b) is correct.
Given that, Line (1): 8x-4 = 2(4x+1)-6, so we will procced to solve line (1) accordingly and then with the steps we will find where the error exactly occur. Let's proceed to solve this question.
8x-4 = 2(4x+1)-6
Now, open or simplify the bracket in RHS, we get
8x-4 = 8x+2-6
Now, simplify RHS accordingly, we get
8x-4 = 8x-4
Now add 4 both sides, we get
8x-4+4 = 8x-4+4
8x = 8x
Now, divide both sides by 8, we get
x = x
Now, subtract x from both sides, we get
0 = 0
Both sides are equal.
⇒ True for all x.
So, from the above calculation steps we can easily concluded that the error occurred from line (2) to line (3).
Hence, option(b) is correct.

Step-by-step explanation:
The table shows a proportional relationship.
Workout (hours) 1 2 3

Create a description in words for the table.
The number of calories burned is dependent on the number of hours working out. For a one-hour workout, there are 240 calories burned, and for a two-hour workout, there are 480 calories burned.
The number of calories burned is dependent on the number of hours working out. For every 240-hour workout, there is 1 calorie burned, and for every 480-hour workout, there are 2 calories burned.
The number of hours working out is dependent on the number of calories burned. For a one-hour workout, there are 240 calories burned, and for a two-hour workout, there are 480 calories burned.
The number of hours working out is dependent on the number of calories burned. For every 240-hour workout, there is 1 calorie burned, and for every 480-hour workout, there are 2 calories burned.
Answer: The number of calories burned is dependent on the number of hours working out. For a one-hour workout, there are 240 calories burned, and for a two-hour workout, there are 480 calories burned.
Step-by-step explanation:
By observing the nature of the question, we can decide that the amount of time spent working out dictates the number of calories we burn, making the workout (hours) the independent variable and the calories burned the dependent. This automatically cancels out the answers C and D.
We then just use our knowledge of the table. The hours were assigned 1, 2, and 3, and the calories were 240, 480, and 720. Just make sure the answer reflects that! That gives us answer choice B, The number of calories burned is dependent on the number of hours working out. For a one-hour workout, there are 240 calories burned, and for a two-hour workout, there are 480 calories burned.

We are given the coordinates of two points as:
S = ( - 2, 4 )
T = ( 3, 9 )
We have to find the distance between the points S and T.
We will use the distance formula for this.
Distance = √(x₂ - x₁)² + ( y₂ - y₁)²
Here, we have:
x₁ = -2
x₂ = 3
y₁ = 4
y₂ = 9
Substituting the values in the formula, we get that:
Distance = √(3 + 2)² + ( 9 - 4)² units
Distance = √(5)² + ( 5)² units
Distance = √25 + 25 units
Distance = √50 units
Distance = 5 √2 units
Therefore, we get the distance between the coordinates of the point S and T as 5 √2 units.

first we want to figure out the square roots. the square root of 12 would be 3.5. while the square root of 3 is 1.7
after figuring out the square roots, our equation is -3.5 + 3(1.7)
first we want to multiply 3 by 1.7
this would give us 5.1
leaving our equation as -3.5 + 5.1
our final step is to add 5.1 to -3.5
although i find it easier to just subtract 3.5 from 5.1 since 3.5 is a negative.

Answer:
x = -17
Step-by-step explanation:
You can plug in answer choices, or you can get x by itself.
I got x by itself because it is faster. Simply subtract 15 from both sides.
So, you would get x = -2 - 15. Keep change change to subtract negative numbers => -2 + -15 which equals to -17.
So x = -17.
You can also plug it in: 15 + -17 does equal -2.
