The reflection of the shape over the line p is drawn and added as an attachment
How to reflect the shape over the lineWhen a shape is reflected over a line, it is flipped across that line. The reflected image of the shape is a mirror image of the original shape, and appears to be a mirror image of the original shape.
This means that we simply flip the shape over the line of reflection
The line over which the shape is reflected is called the line of reflection, and it acts as a mirror. In this case, it is the line p. The shape and its reflected image are symmetric with respect to the line of reflection.
Flipping the shape would result in any point on the original shape and its corresponding point on the reflected image are equidistant from the line of reflection, as the distance between a point and its reflected image is equal to twice the perpendicular distance from the point to the line of reflection.

Answers
Easton needs to complete 3 more jumps to reach his goal of completing 70% of the jumps on the skateboard course.
How to determine the additional number of jumps neededEaston's goal is to complete 70% of the jumps on the skateboard course. This means he needs to complete 70% of the total number of jumps.
We know that Easton has already completed 18 jumps out of 30, which is equivalent to completing 60% of the jumps.
The total number of jumps on the skateboard course is 30.
Easton's goal is to complete 70% of the jumps, which is:

Answers
The final factored form of the polynomial is b(a-b) and the category of the remaining polynomial is a binomial.
The first step in factoring out the GCF from the polynomial ab+ay-b^(2)-by is to identify the greatest common factor of all the terms. In this case, the GCF is b. Once we have identified the GCF, we can factor it out from each term by dividing each term by the GCF. This gives us:
ab+ay-b^(2)-by = b(a+y)-b(b+y) = b(a+y-b-y)
Next, we can simplify the remaining polynomial by combining like terms:
b(a+y-b-y) = b(a-b)
Finally, we can identify the category of the remaining polynomial. Since it has two terms and each term has a degree of 1, the remaining polynomial is a binomial.

Answers
The solution to this linear programming problem is (x,y) = (3,4) and f = 22.
To solve this linear programming problem, we need to find the feasible region by graphing the constraints and then use the objective function to find the maximum value of f.
1. Graph the constraints:
x + y ≤ 7 can be rewritten as y ≤ -x + 7
2x + y ≤ 12 can be rewritten as y ≤ -2x + 12
y ≤ 4
2. Find the feasible region:
The feasible region is the area that satisfies all of the constraints. In this case, it is the area bounded by the three lines and the x and y axes.
3. Use the objective function to find the maximum value of f:
f = 2x + 4y
To find the maximum value of f, we need to find the corner points of the feasible region and plug them into the objective function. The corner points are (0,4), (3,4), and (4,3).
f(0,4) = 2(0) + 4(4) = 16
f(3,4) = 2(3) + 4(4) = 22
f(4,3) = 2(4) + 4(3) = 20
The maximum value of f is 22 at the point (3,4).
Therefore, the solution to this linear programming problem is (x,y) = (3,4) and f = 22.

Answers
To show that the system AX = B is equivalent to the upper-triangular system UX = Y and find the solution, we need to use the Gaussian elimination method. The Gaussian elimination method is a process of reducing a system of linear equations to an equivalent upper-triangular system.
Step 1: Write the given system of equations in matrix form:
```
| 2 -2 5 | | x1 | | 6 |
| 2 3 1 | * | x2 | = | 13 |
|-1 4 -4 | | x3 | | 3 |
```
Step 2: Use the Gaussian elimination method to reduce the matrix to an upper-triangular form:
```
| 2 -2 5 | | 6 |
| 0 7 -9 | = | 7 |
| 0 0 9/7| | 18/7|
```
Step 3: Write the upper-triangular system in equation form:
```
2x1 - 2x2 + 5x3 = 6
0x1 + 7x2 - 9x3 = 7
0x1 + 0x2 + 9/7x3 = 18/7
```
Step 4: Solve the system using back substitution:
```
x3 = 18/7 * 7/9 = 2
x2 = (7 + 9*2)/7 = 4
x1 = (6 + 2*2 - 5*2)/2 = 1

Shea runs a carpet cleaning business. The average cost to shea per cleaning is $30. Shea charges $60 per cleaning. Shea’s fixed plus variable costs per month total $1,500. How many carpet cleaning does shea need to do per year to break even?
Answers
Shea needs to do 600 carpet cleaning per year to break even.
What is revenue?
Total revenue is the total amount of money earned by a business from the sale of its products or services during a particular period of time.
To break even, the total revenue Shea generates from the carpet cleaning business must be equal to the total cost of running the business.
Let's first calculate the total cost of running the business per year:
Total Cost = Fixed Costs + Variable Costs
Since the fixed plus variable costs per month total $1,500, the total cost per year would be:
Total Cost = $1,500 x 12
Total Cost = $18,000
Now, let's calculate the profit that Shea makes per cleaning:
Profit per Cleaning = Price per Cleaning - Cost per Cleaning
Profit per Cleaning = $60 - $30
Profit per Cleaning = $30
So, Shea makes a profit of $30 per cleaning.
To break even, the total profit generated by the number of cleanings Shea does per year should be equal to the total cost of running the business per year:
Total Profit = Total Revenue - Total Cost
If x is the number of carpet cleaning Shea needs to do per year to break even, then:
Total Revenue = Price per Cleaning x Number of Cleanings per Year = $60x
Total Profit = Profit per Cleaning x Number of Cleanings per Year = $30x
Setting Total Profit equal to Total Cost:
$30x = $18,000
x = $18,000 / $30
x = 600
Therefore, Shea needs to do 600 carpet cleaning per year to break even.

In a video game each player earns 5 pts for reaching the next level and 15 pts for each coin collected. Make a table to show the relationship between the num of coins collected c and total pts p graph the ordered pairs and analyze the graph.
Answers
Answer:
Here is a table showing the relationship between the number of coins collected and the total points earned:
Number of coins (c) Total points (p)
0 0
1 20
2 35
3 50
4 65
5 80
6 95
7 110
8 125
9 140
10 155
To graph these ordered pairs, we can plot the number of coins collected (c) on the x-axis and the total points earned (p) on the y-axis. Then we can plot each ordered pair as a point on the graph and connect the points with a line. The resulting graph should show a linear relationship between c and p, with a slope of 15 and a y-intercept of 0.
Analyzing the graph, we can see that as the number of coins collected increases, the total points earned also increases at a constant rate. This suggests that collecting coins is an important part of the game, as it significantly increases the player's total score. Additionally, the slope of the line (15) tells us that each additional coin collected is worth 15 points, while reaching the next level is worth only 5 points.

The median of class A is equal to 40.
The median of class B is equal to 8.
The difference between the median of the two classes is 32.
What is a dot plot?In Mathematics, a dot plot can be defined as a type of line plot that is typically used for the graphical representation of a data set above a number line, especially through the use of dots.
Based on the dot plot, the median of class A can be determined by sorting the data set in ascending order;
10, 10, 10, 20, 20, 30, 40, 40, 40, 40, 50, 50, 50, 70, 70
Median of class A = 40.
Based on the dot plot, the median of class B can be determined by sorting the data set in ascending order;
4, 6, 6, 6, 6, 8, 8, 8, 8, 10, 10, 10, 12, 12, 16
Median of class B = 8.
For the difference, we have:
Difference = 40 - 8
Difference = 32.

Suppose that 30% of the applicants for a certain industrial job possess advanced training in
computer programming. Applicants are interviewed sequentially and are selected at random from
the pool. A) Find the probability that the first applicant with advanced training in programming is
found on the fifth interview. B) What is the expected number of applicants who need to be interviewed in order to find
the first one with advanced training
Answers
After calculating the probability we get, there is a 7.20 percent chance that the first candidate will be identified during the fifth interview and it should take 3.33 interviews to discover the first candidate.
The quantity X of repeated trials needed to obtain r successes with p probability in a binomial experiment is known as the negative binomial distribution.
When x succeeds after n tries, the probability is given by:
P(X-x) = Cn-1, x-1*p(power x) * (1 - p)power (n-x)
The number of unique combinations of x items from a set of n elements, Cn,x, is determined by the formula below.
Cn,x = n! / x! ( n! - x! )
This problem involves that:
Let's say that 30 percent of those who apply for a certain industrial position have advanced expertise in computer programming. That follows that.
(a) We need to determine the probability that the first applicant with advanced programming training will be discovered during the fifth interview.
This is the likelihood that it will take 5 attempts to get 1 success.
So, n=5, x=1
P(X-x) = Cn-1, x-1*p(power x) * (1 - p)power (n-x)
P(X-5) = C 4,0* (0.30)(power 1) * (0.70)power (4)
= 0.0720.
During the sixth interview, there is a 7.20% chance that the first candidate with advanced programming training will be discovered.
(b) To find how many applicants should be expected to be interviewed in order to select the first candidate with advanced training, calculate
It is stated by how many trials are anticipated to result in r success:
E = r/p
Thus with the value r=1
E = r/p
= 1/0.3
= 3.33.
For the first candidate with advanced training, it will take an average of 3.33 interviews.

Explanation:
Find the gradient by using the formula:
(y2 - y1)/(x2 - x1)
Select the points that creates a good dy/dx.
In other words, find points that makes a good comparison with each other to see where the slope is going in the graph.
Answer:
-3/2
Step-by-step explanation:
To find:-
Slope of the line.Answer:-
We are interested in finding out the slope of the given line . We can see that the line passes through the points (1,0) and (-1,3) . For finding out the slope we can use the formula,
[tex]:\implies \sf m =\dfrac{y_2-y_1}{x_2-x_1} \\[/tex]
Now on substituting the respective values, we have;
[tex]:\implies \sf m = \dfrac{0-3}{1-(-1)} \\[/tex]
[tex]:\implies \sf m = \dfrac{-3}{1+1}\\[/tex]
[tex]:\implies \sf \pink{m=\dfrac{-3}{2}}\\[/tex]
Hence the slope of the line is -3/2.
