To find the OGF for the number of ternary sequences in which any occurrence of 2 has a 1 both immediately before and immediately after it, we can use a recursive approach.
Let A(x) be the OGF for sequences that start with a 1 and end with a 1. And let B(x) be the OGF for sequences that start with a 1, contain a 2, and end with a 1.
We have A(x) = x + [tex]x^{2}[/tex] + [tex]x^{3}[/tex] + [tex]x^{4}[/tex] + ...
And B(x) = x * [tex]A(x)^{2}[/tex], since a 2 can only appear after a 1 and must be immediately followed by another 1.
Finally, the OGF for the desired sequence is B(x) = x * x + [tex]x^{2}[/tex] + [tex]x^{3}[/tex] + [tex]x^{4}[/tex] + ...)^2 = x * [tex]A(x)^{2}[/tex]
So, the OGF for the number of ternary sequences in which any occurrence of 2 has a 1 both immediately before and immediately after it is x * ( x + [tex]x^{2}[/tex] + [tex]x^{3}[/tex]......)^2.
The ordinary generating function (OGF) for a sequence is a formal power series that encodes information about the sequence.

what is the probability that the digit 7 doesn’t appear among 100 digits where each digit is one of (0-9) and all sequences are equally likely?
The probability that the digit 7 doesn't appear among 100 digits is 9/10, or 90%.
The probability that the digit 7 doesn't appear among 100 digits where each digit is one of (0-9) and all sequences are equally likely is given by the probability that all 100 digits are chosen from the set {0, 1, 2, 3, 4, 5, 6, 8, 9}. There are 10 choices for each digit, so there are 10^100 possible sequences of 100 digits. The number of sequences that don't contain the digit 7 is 9^100. Therefore, the probability that the digit 7 doesn't appear among 100 digits is: P(7 doesn't appear) = (9^100) / (10^100) = 9 / 10
Therefore, the probability that the digit 7 doesn't appear among 100 digits is 9/10, or 90%.

the points o(0,0,0), p(,,), and q(,,) lie at three vertices of a parallelogram. find all possible locations of the fourth vertex.
The two possible locations for the fourth vertex of the parallelogram are p and q.
The fourth vertex of a parallelogram can be obtained by adding the vector difference between two of its vertices to the third vertex. In this case, the vector difference between two vertices can be found by subtracting one vertex from the other, i.e. p-o and q-o. So, the fourth vertex can be found by adding either of these vectors to vertex o, i.e. r = p - o + o = p or r = q - o + o = q.
Therefore, the two possible locations for the fourth vertex of the parallelogram are p and q.

evaluate the limit, if it exists. (if an answer does not exist, enter dne.) lim x → 8 12−x − 2 24−x − 4
The limit does not exist as x approaches 8 for (√(12−x) − 2)/ (√(24−x) − 4).
Therefore the answer is dne.
The square root of 12 - x approaches 2 as x approaches 8 and the square root of 24 - x approaches 4 as x approaches 8.
The limit fails to exist because both the numerator and the denominator approach 0 as x approaches 8, but the ratio of the two approaches positive infinity. This shows that the limit is undefined or "dne".
As both the numerator and denominator approach 0, the fraction they form can approach any real number or it can oscillate between two values, leading to an undefined limit. In such cases, the limit fails to exist.

Classifying polynomials refers to categorizing polynomials based on the degree of the polynomial and the number of terms in the polynomial.
The degree of a polynomial is the highest exponent in the polynomial. Polynomials can be classified into several types, including constant polynomials (degree 0), linear polynomials (degree 1), quadratic polynomials (degree 2), and so on. Adding and subtracting polynomials is the process of combining two or more polynomials by combining like terms. Like terms are terms with the same variable and exponent. To add or subtract polynomials, simply line up the terms with the same variable and exponent and add or subtract the coefficients. The result will be a new polynomial with the combined terms.
For example, to add the polynomials [tex]2x^2 + 3x + 4[/tex] and [tex]-x^2 + 5x - 6[/tex], we line up the terms with the same variable and exponent and add the coefficients:

Write a compound inequality to represent the possible monthly salary m of an entry-level mechanical engineer in Texas.
Answer:
$5,250 ≤ m ≤ $6,125
Step-by-step explanation:
A compound inequality is a mathematical statement that combines two inequality statements using "and" or "or". In this case, the compound inequality represents the range of possible monthly salary for an entry-level mechanical engineer in Texas.
The average salary for this position ranges from $63,000 to $73,500 per year. To find the monthly salary, we need to divide these amounts by 12 months, which gives us the minimum and maximum monthly salary:
$63,000/12 = $5,250
$73,500/12 = $6,125
Therefore, the compound inequality is:
$5,250 ≤ m ≤ $6,125
This means that the monthly salary of an entry-level mechanical engineer in Texas could be anywhere between $5,250 and $6,125.

A)92. 8%
B)73. 8%
C)87. 3%
D)37. 4%
The probability that the battery will last for 52 months is approximately 0.928, or 92.8%.
To calculate the probability that a battery will last for 52 months, we need to find the z-score of 52 months, using the formula:
z = (x - μ) / σ
Plugging in the values, we get:
z = (52 - 42.5) / 6.5 = 1.384615
Next, we can use a z-table to find the probability that a battery will last more than 52 months.
In this case, the z-score is positive, so we look up the area to the right of 1.384615 in the z-table. The area to the right of 1.384615 is approximately 0.928.
Therefore, the probability that a battery will last for 52 months or more is approximately 0.928, or 92.8%.

Step-by-step explanation:
consider the following mixture problem and the table used to translate the problem Drink A is 20% fruit juice and drink B is 5% fruit juice. how much should be used in order to make 30 gal of a drink that is 10% fruit juice? complete the following table letting x=gallons of drink A and y=gallons of drink B.
Substance Gallons % Fruit Juice
Drink A x 20%
Drink B y 5%
Total x + y = 30 10%
To find the number of gallons of Drink A and Drink B that should be used, we can write two equations based on the percentage of fruit juice.
20% * x = 10% * (x + y)
5% * y = 10% * (x + y)
Simplifying and solving for x and y:
x = 1.5 * y
10% * (x + y) = 10% * 30
y = 15
x = 1.5 * 15 = 22.5
So, we would use 22.5 gallons of Drink A and 15 gallons of Drink B to make a 30 gallon mixture that is 10% fruit juice.

Since C is any arbitrary constant, [tex]y^{2} = \frac{1}{5} ln (3 + x^{10}) + 2C[/tex] is the final solution of the differential equation.
The equation given to us is:
[tex](3 + x^{10})\frac{dy}{dx} = \frac{x^{9}}{y}[/tex]
We can re-write the above equation:
[tex]y dy = \frac{x^9}{3 + x^{10}} dx[/tex]
This is separation of variables.
A separable differential equation is any equation that can be written in the form y′=f(x)g(y). The method of separation of variables is used to find the general solution to a separable differential equation.
Now, if we differentiate the denominator,
[tex]\frac{d}{dx} (3 + x^{10} ) = 10x^9[/tex]
Integrating both sides,
[tex]\frac{y^2}{2} = \frac{1}{10} ln (3 + x^{10})[/tex] + C
⇒ [tex]y^{2} = \frac{1}{5} ln (3 + x^{10})[/tex] + 2C
Since C is any arbitrary constant, [tex]y^{2} = \frac{1}{5} ln (3 + x^{10}) + 2C[/tex] is the final solution of the differential equation.

consider the following data: −11,−5,−5,−11,13,−11,−5 step 1 of 3 : calculate the value of the sample variance. round your answer to one decimal place.
The value of the sample variance rounded to one decimal place is 76.0.
What is the Mean?
The mean is a measure of the central tendency of a set of data, calculated as the sum of the values divided by the number of values in the set.
The sample variance of a set of data is a measure of the spread or dispersion of the data around the mean. To calculate the sample variance, you can follow these steps:
Calculate the mean of the data: First, find the sum of all the data points and divide by the number of data points (n).
For the given data, the mean is: (-11 + -5 + -5 + -11 + 13 + -11 + -5) / 7 = -7
Subtract the mean from each data point: Next, subtract the mean from each data point to get the deviations from the mean.
For the given data, the deviations are: (-11 - -7) = -4, (-5 - -7) = 2, (-5 - -7) = 2, (-11 - -7) = -4, (13 - -7) = 20, (-11 - -7) = -4, (-5 - -7) = 2
Square the deviations: Square each deviation to get rid of negative values.
For the given data, the squared deviations are: (-4)^2 = 16, (2)^2 = 4, (2)^2 = 4, (-4)^2 = 16, (20)^2 = 400, (-4)^2 = 16, (2)^2 = 4
Sum the squared deviations: Sum all the squared deviations.
For the given data, the sum of the squared deviations is: 16 + 4 + 4 + 16 + 400 + 16 + 4 = 456
Divide the sum by n - 1: Finally, divide the sum of the squared deviations by the number of data points minus 1 (n - 1). This gives us the sample variance.
For the given data, the sample variance is: 456 / (7 - 1) = 456 / 6 = 76
Hence, the value of the sample variance rounded to one decimal place is 76.0.
