11. Members of the student council are conducting a fundraiser by selling school calendars. After selling 80 calendars, they had a loss of $ 360. After selling 200 calendars, they had a profit of $600. Write an equation that describes the relation between y, the profit or loss, and x, the number of calendars sold. How much profit did they make from selling each calendar? How much would they have lost if they had sold no calendars?
Answers
a) The equation that describes the relation between x and y is y = 8x - 1000
b) They made 8% profit from selling the calendars
c) They will loss 1000 when they sold no calendars.
Given,
Members of student council had a loss of $360 after selling 80 calenders
They made a profit of $600 after selling 200 calenders.
y be the profit or loss
x be the calendars sold
We have to find the following;
a) The equation of the line in Slope-Intercept form is:
y = mx + b
Where "m" is the slope and "b" is the y-intercept.
We are aware that "y" here stands for the profit or loss and "x" for the quantity of calendars sold.
Then,
According to the exercise, the line passes through these two points:
(80, -360) and (200, 600)
Then,
We can find the slope of the line with the formula;
m = (y₂ - y₁) / (x₂ - x₁)
m = (-360 - 600) / (80 - 200)
m = -960/-120
m = 8
Now,
We can substitute the slope and one of those points into y = mx + b and solve for "b":
600 = 8 × 200 + b
-b = 1600 - 600
b = -1000
Then,
Substituting values, we get that the equation that describes the relation between the profit and loss and the number of calendars sold, is:
y = 8x - 1000
b) The slope of the line is the profit they made from selling each calendar
Profit = 8
c) The y-intercept is the amount they would have lost if they had sold no calendars:
b = -1000
They'd have lost $1000 if they had sold no calendars.

In this case, the coefficient of determination is 0.5297, which means that 53% of the sample variation in Final grades is explained by the sample regression equation.
The data file contains the midterm and final scores of 32 students in a statistics course. To estimate a student's final score as a function of their midterm score, we used a regression analysis. The regression equation was Final = 27.5818 + 0.6774 Midterm. This equation can be used to predict the final score of a student based on their midterm score. The standard error of the estimate was 14.947. This indicates the accuracy of the estimated final score. The coefficient of determination was 0.5297, which means that 53% of the sample variation in final grades is explained by the regression equation. This tells us that the regression equation is a relatively good predictor of a student's final score.
Given:
Midterm Score = x
Final Score = y
Regression Equation: y = 27.5818 + 0.6774x
Standard Error of the Estimate = 14.947
Coefficient of Determination = 0.5297
Calculating Final Score:
y = 27.5818 + 0.6774x
y = 27.5818 + 0.6774(x)
y = 27.5818 + 0.6774(x)
y = 27.5818 + 0.6774(x)
y = 27.5818 + 0.6774x
Final Score = 27.5818 + 0.6774(Midterm Score)

Find the vector v with an initial point at (5, 7) and a terminal point at (2, 10). write your answer in component form. then write the vector v as a linear combination of the unit vectors i and j. finally, find the length of the vector.
Answers
The length of the vector v is approximately 4.24. A vector is a mathematical object that has both magnitude and direction
Vectors are commonly used in physics, engineering, and other fields to represent quantities that have both magnitude and direction, such as velocity, acceleration, and force. They are also important in linear algebra, where they can be used to represent lines and planes in space, and to solve systems of linear equations.
The vector v can be expressed in component form as v = <2-5, 10-7> = <-3, 3>.
To express the vector v as a linear combination of the unit vectors i and j, we can write it as v = (-3)i + 3j.
To find the length of the vector, we can use the Pythagorean theorem:
length of v = sqrt((-3)^2 + 3^2) = sqrt(9 + 9) = sqrt(18) = 3*sqrt(2) = 4.24

The value of x from the triangle is x = 31
What are similar triangles?
If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be ABC
The measure of side AB = 14.5
The measure of side BC = 15.5
Let the second triangle be XYZ
The measure of side XY = 29
The measure of side YZ = x
Now , if the triangle ABC is similar to triangle XYZ , then the corresponding sides of the triangles will be equal in ratio
So , the equation will be
XY / AB = YZ / BC
Substituting the values in the equation , we get
29 / 14.5 = x / 15.5
On simplifying the equation , we get
x/15.5 = 2
Multiply by 15.5 on both sides of the equation , we get
x = 2 x 15.5
x = 31
Therefore , the value of x is 31
Hence , the value of x of side YZ is 31

Answers
Answer:
The exact value of x so that the greatest possible amount of light is emitted is 8.96ft.
What is the perimeter of a semicircle?
The perimeter of a semicircle is half that of a circle, that is [tex]\pi r[/tex], where r is the radius of the circle.
Step-by-step explanation:
Given the width of the rectangle is x, let the height of the rectangle be y.
The radius of the semicircle is x/2.
The perimeter of the window is equal to [tex]2y+x+\pi \frac{x}{2} =32[/tex].
The area of the window is [tex]xy+\frac{1}{2}(\pi )(\frac{x}{2})^2=xy+\frac{\pi x^2}{8}[/tex].
We can insert into the formula for the area to obtain the area in terms of only x by solving the equation for the perimeter of y in terms of x.
[tex]2y=32-(1+\frac{\pi }{2} )x=32-(\frac{2+\pi }{2} )x\\y=16-(\frac{2+\pi }{4} )x[/tex].
Now the area of the window in terms of only x is:
Area=[tex]16x-(\frac{2+\pi }{4} )x^2+\frac{\pi x^2}{8}[/tex].
Since it is given in the question that maximum light should be admiitted, we will differentiate the Area and set it to 0.
[tex]16-2(\frac{2+\pi }{4} )x+\frac{\pi x}{4}=0\\ 16=x(1+\frac{\pi }{4})\\ x=\frac{16}{1+\frac{\pi }{4}} \\x=8.96ft[/tex].
Therefore the exact value of x is 8.96ft.

Given the numbers of students in various combinations of three courses, you want the associated Venn diagram and some numbers associated with additional combinations of courses.
Venn diagramIt is often easiest to populate the numbers in a Venn diagram by starting with the center one: 286 are taking all three courses. (V. = 286)
Working outwards from there, the numbers taking two courses can be filled in: (II. = History & Dance - V. = 343; IV. = History & Math - V. = 319; VI. = Dance & Math - V. = 318.)
Finally, the number taking a single course can be found. (I. = History -II. -IV. -V.; III. = Dance -II. -V. -VI.; VII. = Math -IV. -V. -VI.)
Adding all the numbers found so far gives the total in History, Dance, or Math (question 4). The difference between the number surveyed and the number in courses is VIII, the number taking none of the courses (question 5).
History or Not DanceThe least arithmetic may be involved if you rewrite this expression to ...

11) Solve for n in s=(n-2) 180
A) n=180 s+2
B) n=(s-2) . 180
C) n=s/180-2
D) n=s/180+2
Answers
For the given equation the value of n is equal to option D.
n = (s/180) + 2.
As given in the question,
Given equation is equal to :
s = (n-2)180
Now take all the terms on one side and term n on other side of the equation we have,
Divide both the side by 180 we get,
s/ 180 = [(n-2)180]/180
s/180 = n -2
Add 2 both the side of the equation we get,
(s/180 ) + 2 = n -2 + 2
(s/180 ) + 2 = n
so here the value is equal to
n = (s/180) +2.
Therefore, the value of n in the equation is equal to option D.
n = (s/180) + 2.

Find length and width of a rectangle with minimum perimeter that has an area of 5A square cm
length=
width=
Answers
By taking minimum perimeter the value of length and width will both be [tex]\sqrt{5A}[/tex].
What is perimeter?Perimeter is basically the sum of all sides of a figure.
How to calculate perimeter of rectangle?The perimeter of a rectangle is 2l + 2w where l = length and w = width of rectangle.
Since the perimeter needed in this question is minimum, the figure must be a square and not a rectangle. For a square, area = a^2
5A = a^2
a = l = w = [tex]\sqrt{5A}[/tex]
Hence, both the length and width are equal to [tex]\sqrt{5A}[/tex].
