What is the solution to 5(2n+4)=−2(4n−1) ?
Answer: n= -1
Step-by-step explanation:
simplify by distributing:
5(2n+4)=-2(4n-1)
10n+20=-8n+2
add 8n to both sides:
10n+20=-8n+2
+8n +8n
————————
18n+20=2
subtract 20 from both sides
18n+20=2
-20 -20
————————
18n=-18
divide both sides by 18:
18n/18 = -18/18
n = -1

We now rewrite the equation:

Now remember that:

And that if

Therefore, we can now simplify the equation.

The percentage of cotton in material used to manufacture men's shirts follows.
a. Construct a stem-and-leaf display for the data.
b. Calculate the median and quartiles of these data.
33.2 37.8 34.6 33.0 32.8 36.1 34.3 35.5 32.9 36.6 34.1 33.0 33.2 36.4 32.5

32.9 35.0 35.4 33.2
Answer:
Median = 34.55
Quartiles:
Q1 = 33.1
Q2 = 34.55
Q3 = 35.6
Inter Quartile range = 2.5
Step-by-step explanation:
Step 1
We arrange the given the following data from lowest to the highest
32.0, 32.1, 32.1, 32.2, 32.4, 32.5, 32.5, 32.5, 32.8, 32.8, 32.8, 32.8, 32.9, 32.9, 33.0, 33.0, 33.2, 33.2, 33.2, 33.2, 33.5, 33.6, 33.8, 33.8, 33.9, 34.0, 34.0, 34.1, 34.1, 34.3, 34.4, 34.5, 34.6, 34.6, 34.6, 34.7, 34.7, 35.0, 35.0, 35.1, 35.1, 35.2, 35.4, 35.5, 35.5, 35.5, 35.5, 35.6, 35.6, 36.1, 36.3, 36.4, 36.4, 36.4, 36.5, 36.6, 36.7, 36.7, 37.0, 37.1, 37.4, 37.4, 37.6, 37.8
a. Construct a stem-and-leaf display for the data.
Stem and leaf Display
Stem | Leaf
32 | 0,1,1,2,4,5,5,5,8,8,8,8,9,9
33 | 0,0,2,2,2,2,5,6,8,8,9
34 | 0,0,1,1,3,4,5,6,6,6,7,7
35 | 0,0,1,1,2,4,5,5,5,5,6,6,
36 | 1,3,4,4,4,5,6,7,7,
37 | 0,1,4,4,6,8
b. Calculate the median and quartiles of these data.
Number of terms = 64
1) Median = 1/2(n + 1)th value
n = 64
= 1/2(64 + 1)th
= 1/2(65)th
= 32.5 th value
This means it is between the 32nd and 33rd value
32nd = 34.5
33rd = 34.6
= 34.5 + 34.6/2
= 69.1/2
= 34.55
2) First Quartile
1/4(n + 1)th value
n = 64
= 1/4(64 + 1)th
= 1/4(65)th
= 16.5th value
This means it is between the 16th and 17th value
16th value = 33.0
17tj value = 33.2
= 33.0 + 33.2/2
= 66.2/2
= 34.55
Q1 --> 33.1
3)Second Quartile = Median
1/2(n + 1)th value
n = 64
= 1/2(64 + 1)th
= 1/2(65)th
= 32.5 th value
This means it is between the 32nd and 33rd value
32nd = 34.5
33rd = 34.6
= 34.5 + 34.6/2
= 69.1/2
= 34.55
Q2 --> 34.55
Third Quartile
3/4(n + 1)th value
n = 64
= 3/4(64 + 1)th
= 3/4(65)th
= 48.75 th value
This means it is towards the 49th value
32nd = 34.5
Hence,
Q3 --> 35.6
Inter Quartile range
Q3 - Q1
= 35.6 - 33.1
= 2.5
Solve for x.
3x/2 = 15
x = 10 1/2
x = 1/10
x=22 1/3
x = 10
Answer:
x = 10
Step-by-step explanation:
3x/2 = 15
cross multiply
3x = 15 × 2
3x = 30
divide both sides by the coefficient of x
3x/3 = 30/3
x = 10

What is the future value (total amount due) on a $12,000 loan at 8% compounded
semiannually (twice a year) for 7 years?
Answer: $20,780.10
Step-by-step explanation:
You need the Compound Interest Formula
A = P(1 + r/n)^nt
Step 1: Create the equation.
12,000(1 + 0.08/2)¹⁴
Step 2: Solve the equation.
Follow PEMDAS (parenthesis, exponents, multiplication...)
Parenthesis: (1 + 0.08/2) = (1 + 0.04) = (1.04)
Exponents: (1.04)¹⁴ = (1.73168)
Multiplication: 12,000(1.73168) = 20,780.1

Mai has a jar of quarters and dimes. She takes at least 10 coins out of the jar and has less than $2.00.
Write a system of inequalities that represents the number of quarters, , and the number of dimes, , that Mai could have.
Is it possible that Mai has each of the following combinations of coins? If so, explain or show how you know. If not, state which constraint—the amount of money or the number of coins—it does not meet.
3 quarters and 12 dimes
4 quarters and 10 dimes
2 quarters and 5 dimes
(From Algebra1, Unit 2, Lesson 25.)
Problem 8
A stadium can seat 63,026 people. For each game, the amount of money that the organization brings in through ticket sales is a function of the number of people, , in attendance.
If each ticket costs $30.00, find the domain and range of this function.
Answer:
The system of inequalities that can represent the situation is25q+0.1d<2.00 and x+y≥10.
Yes, it is possible because 3 + 12≥10 and 3 quarters and 12 dimes total $1.95 which is less than $2.00.
This is not possible because 4 quarters and 10 dimes is exactly $2.00, which is not less than $2.00.
This is not possible because 2 quarters and 5 dimes is only 7 coins, which is not at least 10 coins.

Step-by-step explanation:
You are building a rectangular flowerbed for your back yard. The flowerbed will surround the flowers and sit on the ground. The
ground where you want to plant the flowers is 4 ft. by 7 ft. How many feet of boards will you need to build the flowerbed? Your
answer should be a number only.
Given parameters:
Dimension of the flowerbed = 4ft by 7ft
Unknown:
Number of feet to build the flowerbed = ?
Since the flowerbed will be surrounding the flows, we should simply find the perimeter of the bed.
This is a rectangular area;
Perimeter = 2(L + B)
Input the parameters and solve;
Perimeter = 2 (4 + 7)
Perimeter = 2 x 11 = 22cm
The perimeter of the board is 22cm
