Given:
AB is formed by A(-10, 3) and B(2,7). If line l is the perpendicular bisector of AB.
To find:
The equation of line l in slope intercept form.
Solution:
Slope formula:
\(m=\dfrac{y_2-y_1}{x_2-x_1}\)
Slope of line AB is
\(m_1=\dfrac{7-3}{2-(-10)}\)
\(m_1=\dfrac{4}{2+10}\)
\(m_1=\dfrac{4}{12}\)
\(m_1=\dfrac{1}{3}\)
Product of slopes of two perpendicular lines is -1.
\(m_1\times m_2=-1\)
\(\dfrac{1}{3}\times m_2=-1\)
\(m_2=-3\)
Midpoint of AB is
\(Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)\)
\(Midpoint=\left(\dfrac{-10+2}{2},\dfrac{3+7}{2}\right)\)
\(Midpoint=\left(\dfrac{-8}{2},\dfrac{10}{2}\right)\)
\(Midpoint=\left(-4,5\right)\)
The perpendicular bisector of AB (i.e., line l)passes through he midpoint of AB, i.e., (-4,5) and having slope -3.
So, the equation of line l is
\(y-y_1=m(x-x_1)\)
\(y-5=-3(x-(-4))\)
\(y-5=-3(x+4)\)
\(y=-3x-12+5\)
\(y=-3x-7\)
Therefore, the equation of line l in slope intercept form is \(y=-3x-7\).

15. Give an example of four positive integers such that any three of them have a common divisor greater than although only +1 divide all four of them.
We can say that there are no four positive integers a, b, c, and d such that any three of them have a common divisor greater than 1, although only +1 divide all four of them.
Let's say that the four positive integers are a, b, c and d.
As per the given statement, although only +1 divide all four of them. Therefore, we can say that the four numbers are co-prime to each other. That is, the only common divisor they have is +1.
So, let us now assume that any three of the given numbers have a common divisor greater than 1. Let us suppose that the numbers a, b, c have a common divisor greater than 1. Then we can write the numbers as follows:
a = xk1
b = xk2
c = xk3
d = p
where x is the greatest common divisor of a, b, c and p is a prime number, and k1, k2, and k3 are positive integers. Since a, b, and c have a common divisor, we can say that x > 1.
Hence, the fourth number d can be written as follows:
d = xy
where y is an integer, not equal to k1, k2, or k3. We now need to prove that d is co-prime to a, b, and c. Since x is the greatest common divisor of a, b, and c, x cannot divide d.
Hence, the only common divisor that d shares with a, b, and c is +1.
Therefore, we can say that there are no four positive integers a, b, c, and d such that any three of them have a common divisor greater than 1, although only +1 divide all four of them.

Suppose Aaron is going to burn a compact disk (CD) that will contain 13 songs. In how many ways can Aaron arrange the 13 songs on the CD? Aaron can bum the 13 songs on the CD in different ways Enter your answer in the answer box
Aaron can arrange the 13 songs on the CD in 6,227,020,800 different ways.
To determine the number of different ways Aaron can arrange the 13 songs on the compact disk (CD), we need to find the total number of permutations for the songs. Since there are 13 songs, we can calculate this using the formula:
Permutations = 13!
Step-by-step explanation:
1. Calculate the factorial of 13 (13!).
2. The factorial function is the product of all positive integers up to that number (e.g., 5! = 5 x 4 x 3 x 2 x 1).
So, 13! = 13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 6,227,020,800
Therefore, Aaron can arrange the 13 songs on the CD in 6,227,020,800 different ways.

at the north campus of a small liberal arts college, 10% of the students are women. at the south campus, 50% of the students are women. the campuses are merged into one new central campus. if 40% of the 1200 students at the central campus are women, how many students did each of the north and south campuses have before the merger?
The North Campus had 120 students and the South Campus had 1080 students before the merger, as 10 percentage and 90% of the 1200 students at the Central Campus were from the North and South Campuses respectively.
The first step in solving this problem is to calculate the total number of students at both campuses before the merger. We know that the North Campus had 10% of its students as women and that the South Campus had 50% of its students as women. This means that the North Campus had 10% of its students as women, and the South Campus had 90% of its students as men. By multiplying these percentages by the total number of students at the Central Campus (1200), we can determine that the North Campus had a total of 120 students (10% of 1200) and the South Campus had a total of 1080 students (90% of 1200). Thus, the North Campus had 120 students and the South Campus had 1080 students before the merger.

and then used the predict() function to make a prediction for each student's number of hours exercised per week, what value would it predict for each student?
the predict() function takes as input a linear regression model and a set of predictor variables (in this case, the students' GPA) and returns a set of predicted response values (in this case, the number of hours exercised per week) based on the fitted model.
The specific value that the predict() function would predict for each student's number of hours exercised per week would depend on the coefficients and intercept of the linear regression model that was fitted to the data. These coefficients reflect the relationship between the predictor variable (GPA) and the response variable (number of hours exercised per week) and determine how changes in the predictor variable are associated with changes in the response variable.
The intercept represents the predicted value of the response variable when the predictor variable is zero. Therefore, the predict() function would use these coefficients and intercept to predict the number of hours exercised per week for each student based on their GPA.

suppose that the 13th term of an arithmetic sequence is 46 and the fourth term is 100. find the expression for the general term.
To solve this problem, we need to use the formula for the nth term of an arithmetic sequence:
an = a1 + (n-1)d where a1 is the first term, d is the common difference, and n is the term number. This means that the first term is 118, the common difference is -6, and each subsequent term is found by subtracting 6 from the previous term.
We know that the 4th term is 100, so we can substitute this into the formula:
a4 = a1 + (4-1)d
100 = a1 + 3d
Similarly, we know that the 13th term is 46:
a13 = a1 + (13-1)d
46 = a1 + 12d
Now we have two equations with two unknowns (a1 and d), which we can solve by elimination or substitution. I will use elimination:
100 = a1 + 3d
-46 = -a1 - 12d
------
54 = -9d
d = -6
Now we can substitute d back into one of the equations to solve for a1:
100 = a1 + 3(-6)
a1 = 118
Therefore, the expression for the general term of the arithmetic sequence is:
an = 118 - 6(n-1) or an = 124 - 6n

4. Point P is plotted on the number line. What number is represented by point P?
On the number line, the point P represents the number \(5.7\times10^{-3}\).
What is a number line?
A picture of numbers on a straight line is called a number line. It serves as a guide for contrasting and arranging numbers. Any real number, including all whole numbers and natural numbers, can be represented by it.
There are a total of 11 points on the number line, and the distance between each point is the same.
We can use this fact to find the number represented by point P.
The distance between the 1st point and the 11th point is -
\(6\times10^{-3} - 5\times10^{-3} = 1\times10^{-3}\)
Since there are 11 points in total, the distance between each point is \((1\times10^{-3}) / 10 = 0.1\times10^{-3}\).
Therefore, the distance between the 1st point and the 8th point is 7 times the distance between each point -
distance = \(7 \times (0.1\times10{^-3}) = 0.7\times10^{-3}\)
To find the number represented by point P, we add this distance to the value of the 1st point -
\(P = 5\times10^{-3} + 0.7\times10{^-3}\)
\(P = 5.7\times10^{-3}\)
Therefore, the number represented by point P is \(5.7\times10^{-3}\).

what is 3x^2-x-2 factored?
To factor the quadratic expression 3x^2 - x - 2, we need to find two binomials that, when multiplied, give us the original expression.
The factored form of the quadratic expression can be determined by breaking down the middle term (-x) into two terms whose coefficients multiply to give the product of the coefficient of the squared term (3) and the constant term (-2). In this case, the product is -6. We are looking for two numbers whose sum is equal to -1 (the coefficient of the middle term) and whose product is equal to -6.
The numbers that satisfy these conditions are -3 and 2. We can now rewrite the expression using these numbers:
3x^2 - x - 2 = 3x^2 - 3x + 2x - 2
Next, we group the terms and factor by grouping:
(3x^2 - 3x) + (2x - 2) = 3x(x - 1) + 2(x - 1)
Now, we can see that we have a common binomial factor of (x - 1) in both terms. We can factor this out:
3x(x - 1) + 2(x - 1) = (3x + 2)(x - 1)
Therefore, the factored form of the quadratic expression 3x^2 - x - 2 is (3x + 2)(x - 1).

The mean weight of the cartridges is 152.65 grains, rounded to two decimal places.
To calculate the mean of the given sample of cartridge weights, we need to find the sum of all the weights and then divide that sum by the total number of weights.
Sum of weights = 152.4 + 152.1 + 153.0 + 152.4 + 152.5 + 153.2 + 153.0 + 154.0 + 151.6 + 153.3
Sum of weights = 1526.5
Total number of weights = 10
Mean = Sum of weights / Total number of weights
Mean = 1526.5 / 10
Mean = 152.65
Rounding the mean to two decimal places, we get 152.65.
Therefore, the mean weight of the given sample of cartridges is 152.65 grains.
The mean is a measure of central tendency and represents the average weight of the cartridges in the sample. It is calculated by summing up all the weights and dividing by the total number of weights.
In this case, the mean weight of the cartridges is 152.65 grains, rounded to two decimal places. This means that, on average, the cartridges in the sample weigh approximately 152.65 grains.

A translation is a transformation that occurs when a figure is moved from one location to another location without changing its size, shape or orientation.
How to Translate a Triangle
Step 1: Identify the coordinates of each of the vertices of the triangle.
Step 2: Translate each point by adding the horizontal translation value to the x-coordinate of each vertex and the vertical translation value to the y-coordinate of each point. For these translations, add a negative number if the horizontal translation is to the left or if the vertical translation is downward.
Step 3: Plot the three translated points and draw the triangle by connecting each pair of points with a straight line.
Coordinates are written as (x, y) meaning the point on the x axis is written first, followed by the point on the y axis.
