\(n^2 + \frac{2n}{3} + \frac{1}{9} = \frac{1}{9}\) -- Perfect square trinomial
\((n + \frac{1}{3})^2 = \frac{1}{9}\) ---Binomial squared
Step-by-step explanation:
Given
\(n^2 + \frac{2n}{3}\)
Solving (a): Perfect square trinomial
We have:
\(n^2 + \frac{2n}{3}\)
Express as an equation
\(n^2 + \frac{2n}{3} =\)
Start----------------------------
Take coefficient of n i.e. (2/3)
Half it: i.e. (1/3)
Square it: (1/63^2
Add to both sides of the equation
---------------------------End
So, we have:
\(n^2 + \frac{2n}{3} + (\frac{1}{3})^2 = (\frac{1}{3})^2\)
Remove brackets
\(n^2 + \frac{2n}{3} + \frac{1}{9} = \frac{1}{9}\)
Solving (b): Binomial Squared
\(n^2 + \frac{2n}{3} + \frac{1}{9} = \frac{1}{9}\)
Expand
\(n^2 + \frac{n}{3}+ \frac{n}{3} + \frac{1}{9} = \frac{1}{9}\)
Factorize:
\(n(n + \frac{1}{3})+ \frac{1}{3}(n + \frac{1}{3}) = \frac{1}{9}\)
Factor out n + 1/3
\((n + \frac{1}{3})(n + \frac{1}{3}) = \frac{1}{9}\)
Express as square
\((n + \frac{1}{3})^2 = \frac{1}{9}\)

Answer:
B. 144√3 in².
Step-by-step explanation:
Given the following data;
Sides of length = 24 inches
Mathematically, the area of an equilateral triangle is given by the formula;
A = √3 * s²/4
Where, s represents the sides of length.
Substituting into the formula, we have;
A = √3 * 24²/4
A = √3 * 576/4

Simplify the rational expression
7x/14x^6
Answers
The simplified form of the rational expression \((7x)/(14x^6)\) is \(1/(2x^6).\)
To simplify the rational expression \((7x)/(14x^6)\), we can begin by simplifying the numerator and denominator separately.
In the numerator, 7x, we can see that both 7 and x have a common factor of 7. So, we can rewrite the numerator as 7 × x = 7x.
In the denominator, \(14x^6\), we can see that both 14 and x^6 have a common factor of \(2x^6\).
So, we can rewrite the denominator as
\(14 \times x^6 = 2 \times 7 \times x^6 = 2 \times 7x^6.\)
Now, we can simplify the rational expression by canceling out the common factors in the numerator and denominator:
\((7x)/(14x^6) = (7x)/(2 \times 7x^6) \\= (7x)/(2 \times 7 \times x^6) \\= (cross(7x))/(2 \times cross(7) \times x^6) \\= 1/(2x^6)\)
Therefore, the simplified form of the rational expression\((7x)/(14x^6)\) is \(1/(2x^6).\)

A gardener wants to determine which of two brands of fertilizer is best for the plants in a garden. Before using one of the fertilizers on the entire garden, the gardener decides to conduct an experiment using 28 individual plants. Which of the two plans for randomly assigning the treatments should the gardener use? Explain.
Plan A: Choose the 14 unhealthiest-looking plants. Apply Brand X fertilizer to all 14 of those plants. Apply Brand Y fertilizer to the remaining 14 plants.
Plan B: Choose 14 of the 28 plants at random. Apply Brand X fertilizer to those 14 plants and Brand Y fertilizer to the remaining 14 plants.
Plan A, because the unhealthy plants need the fertilizer the most and should be treated first
Plan B, because the sample of plants is randomly chosen
Plans A and B are equivalent because they both follow experimental design
Plans A and B are both poorly designed because there are not enough plants to test
The plans cannot be evaluated from the information given

What is the M.A.D. (mean absolute deviation) of the following data set?
8 9 9 7 8 6 9 8
Answers
The mean absolute deviation is 0.75
How to determine the mean absolute deviationTo calculate the mean absolute deviation (M.A.D.), you need to find the average of the absolute differences between each data point and the mean of the data set
From the information given, we have that the data set is;
8 9 9 7 8 6 9 8
Let's calculate the mean, we get;
Mean = (8 + 9 + 9 + 7 + 8 + 6 + 9 + 8) / 8
Mean = 64 / 8
Divide the values
Mean = 8
Let's determine the absolute difference, we get;
Absolute differences=
|8 - 8| = 0
|9 - 8| = 1
|9 - 8| = 1
|7 - 8| = 1
|8 - 8| = 0
|6 - 8| = 2
|9 - 8| = 1
|8 - 8| = 0
Find the mean of the absolute differences:
Average of absolute differences = (0 + 1 + 1 + 1 + 0 + 2 + 1 + 0) / 8
Absolute difference = 6 / 8 = 0.75

38%
Answers
Answer:
24.5%
Step-by-step explanation:
Given
P(Off-Campus) = 0.30
P(Part-Time Job | Off-Campus) = 0.62
P(Part-Time Job | On-Campus) = 0.65
Inferred
P(On-Campus) = 0.70
P(No Part-Time Job | Off-Campus) = 0.38
P(No Part-Time Job | On-Campus) = 0.35
Calculation
P(No Part-Time Job | On-Campus) = P(No Part-Time Job ∩ On-Campus)/P(On-Campus)
0.35 = P(No Part-Time Job ∩ On-Campus)/0.70
0.245 = P(No Part-Time Job ∩ On-Campus)
Therefore, 24.5% of students that live on campus do not have a part-time job.

The interest for Part 1 is approximately $385.10.
The interest for Part 2 is approximately $709.31.
To calculate the interest for Part 1 and Part 2The formula is as follows:
Interest is calculated as follows: Principal * Rate * Time
Where
Principal represents the starting sumThe interest rate is rateTime measures length in years.Part 1:
$132,000 is the principal.
(Decimal) Rate = 12% = 0.12
Time = 8 days/365 days.
How much interest is there in Part 1?
Interest is calculated as follows : $132,000 * 0.12 * (8/365) = $385.10
Therefore, the interest for Part 1 is approximately $385.10.
Part 2:
$106,750 as the principal
(Decimal) Rate = 12% = 0.12
Time = 20 days / 365 days.
How much interest will there be in Part 2
Interest is calculated as follows : $106,750 * 0.12 * (20/365) = $709.31

If Betty spent $56 to mail her package, how many pounds did it weigh?
Answers
1. The mathematical expression that can be used to determine the total cost of mailing a package weighing p pounds is f(Tc) = 20 + 3p.
2. Since Betty spent $56 to mail her package, the weight in pounds of the mail must be 12 pounds.
What is a mathematical expression?A mathematical expression is a statement containing numbers, variables, and an arithmetic operation.
Flat (fixed) rate for mailing a package = $20
Variable mailing rate per pound = $3
Expression to model the total cost:
Let Tc = total cost
p = number of pounds
Tc = 20 + 3p
If Betty spent $56 to mail her package, the number of pounds, using the mathematical expression above:
Tc = 20 + 3p
56 = 20 + 3p
56 - 20 = 3p
36 = 3p
p = 12
Check:
Tc = 20 + 3p
56 = 20 + 3 (12)
56 = 20 + 36
56 = 56

The solution to given linear inequality, 6(x1.5) + 30 < 48, is x < 2
Solving linear inequalitiesFrom the question, we are to solve the given linear inequality
The given linear inequality is
6(x1.5) + 30 < 48
First, we will write this inequality properly.
The inequality can be properly written as
6(1.5x) + 30 < 48
Now, we will solve the linear inequality
6(1.5x) + 30 < 48
Subtract 30 from both sides of the equation
6(1.5x) + 30 - 30 < 48 - 30
6(1.5x) < 18
Divide both sides of the inequality by 6
6(1.5x)/6 < 18/6
(1.5x) < 3
1.5x < 3
Divide both sides of the inequality by 1.5
1.5x/1.5 < 3/1.5
