I need to write a proportion to the following problem:
3 folders cost $2.91. What written proportion would help determine the cost of 2 folders?
Answer:
The cost of two folder is $ 1.94
Solution:
Given that 3 folders cost $ 2.91
We have to determine the cost of 2 folder
From given,
Cost of 3 folder = $ 2.91
To find the cost of 1 folder, divide 2.91 by 3
Thus cost of 1 folder is $ 0.97
We are asked to find cost of two folders.
Therefore, multiply cost of 1 folder by 2
Thus cost of two folder is $ 1.94
Which equation represents the relation that is shown in the graph?
Cost of Buying Comic Books
On a coordinate plane, a graph titled Cost of Buying Comic Books has number of issues on the x-axis and total cost on the y-axis. A line goes through points (0, 0), (1, 3.5), (2, 7).
y = x + 2/7
y = x + 7/2
y = 2/7 x
y = 7/2x

A person going to a party was asked to bring 4 different bags of chips. Going to the store, she finds 13 varieties.
How many different selections can she make?
(this is a probability question)
Answer:
Step-by-step explanation:
13!/4(13-4)!
13!/4(9)!
Continue simplifying.
The formula for combinations n!/r!(n-r)! pay attention to class next time
"715" are the different selections she can make.
Given:
Number of different begs,
4Total number of varieties,
13So,
Total number of different selection = ¹³C₄
= [tex]\frac{13!}{4!\times (13-4)!}[/tex]
= [tex]\frac{13!}{(4!\times 9!)}[/tex]
= [tex]\frac{13\times 12\times 11\times 10}{4\times 3\times 2}[/tex]

Sample
The 107 undergraduate college students who returned the questionnaire
Step-by-step explanation:
From the question we are told that
The list of undergraduate college students obtained from her university is n= 1196
The number of student that are randomly selected is n = 500
The number of e-mail that was returned is k = 107
The proportion that believes that the federal student loan program needs to be completely overhauled is [tex]\^{p} = 0.71[/tex]
Generally the population for this particular study is
All undergraduate college students at the researcher's university ,
this is because they are the total pool of data from which the statistical sample are randomly selected from
Generally the sample for this particular study is
The 107 undergraduate college students who returned the questionnaire
this is because this data provides us with an insight on the perspective of all undergraduate college students at the researcher's university about federal financial aid

The rectangle below is enlarged using a scale factor of 1.5. What will be the new length and width of the rectangle?
Answer: length = 4.5 m, width = 3 m
Step-by-step explanation:
When a shape is enlarged using a scale factor, you simply multiply each of the sides by the scale factor.
length = 3 * 1.5 = 4.5 m
width = 2 * 1.5 = 3 m

Write an expression for the perimeter of the rectangle. Make sure you expression is as simple as possible. 5x+9 , 3x+12
Answer:
6x+42
Step-by-step explanation:
So by, "5x+9 , 3x+12" I'm assuming you mean the length and the width.
The perimeter of a rectangle is 2(l+w), so if you put the values in, you get...
2(5x+9+3x+12)
2(8x+21)
6x+42, which is your answer.
