The provide a recursive definition for the set of all strings of a’s and b’s where all the strings are of odd lengths, we have to break this into two cases. Base case and Recursive case. To justify the given definition, we need to make sure that the strings have no even number of 'a' and 'b'.

Let's see the Base case:

S = {"a", "b"}

It is defined as S is set of all strings of a’s and b’s.

Now, let's see the Recursive case:

S = {"a", "b"} U {ax | x ∈ S, a ∈ {"a", "b"}} U {bx | x ∈ S, b ∈ {"a", "b"}}

It is defined as the combination with the base case. Since the base case only includes single-character strings of odd lengths, and the recursive case always appends characters to existing strings of odd length. So, there is no chance of formation of even numbers of 'a' and 'b'.

The nominal GDP is equal to $5,200 million.

To calculate the nominal GDP, we can use the formula:

Nominal GDP = Consumption Expenditures + Gross Private Domestic Investment + Government Expenditures + Exports - Imports

Given the following information:

Consumption Expenditures = $3,600 million

Gross Private Domestic Investment = $1,000 million

Government Expenditures = $1,000 million

Exports = $800 million

Imports = $1,200 million

Plugging in these values into the formula, we have:

Nominal GDP = $3,600 million + $1,000 million + $1,000 million + $800 million - $1,200 million

Simplifying, we get:

Nominal GDP = $5,200 million

Therefore, the nominal GDP is equal to $5,200 million.

```sql

SELECT ROUND(AVG(Weight), 0) AS average_weight FROM your_table_name WHERE Destination = 'Atlanta' AND MONTH(Shipping Date) IN (11, 12);

```

Replace `your_table_name` with the actual table name.

To calculate the average weight of a shipment going to Atlanta with a shipping date in November or December, you can use the AVG function along with the ROUND function in a database query or spreadsheet software.

Assuming you have a table with columns "Shipping Date" and "Weight," and you want to filter shipments going to Atlanta with shipping dates in November or December, the SQL query would look like this:

```sql

SELECT ROUND(AVG(Weight), 0) AS average_weight

FROM your_table_name

WHERE Destination = 'Atlanta'

AND MONTH(Shipping Date) IN (11, 12);

```

Replace `your_table_name` with the actual name of your table. The `MONTH(Shipping Date)` function extracts the month number from the "Shipping Date" column, and the `IN (11, 12)` filters the rows for November or December.

The result of the query will be the average weight of shipments going to Atlanta with shipping dates in November or December, rounded to the nearest pound.

Connective tissue bands called annular ligaments prevent flexor tendons of the forearm and leg from rising like bowstrings.

Annular ligaments are ring-like structures made of fibrous tissue that surround and hold tendons in place as they pass through tight spaces in the body. In the forearm, the annular ligaments hold the tendons of the flexor muscles in place as they pass under the wrist and into the hand.

In the leg, the annular ligaments hold the tendons of the hamstring muscles in place as they pass behind the knee.

Without annular ligaments, the tendons would be able to move too freely, causing them to bowstring and reducing their effectiveness in controlling movement. The annular ligaments help to keep the tendons in the correct position, allowing them to function properly and enabling smooth and efficient movement of the joints.

According to the solution we have come to find that, With the help of given ratios, the amount of money spent for 5 food samples would be $12.50.

What is ratio?

A ratio is a comparison of two quantities that expresses how many times one quantity is contained in the other.

From the given data, we can observe that there is a relationship between the number of food samples tasted and the amount of money spent. To find this relationship, we can calculate the ratio of money spent to the number of food samples tasted:

For the first sample, the ratio is 7.50/3 = 2.50.

For the second sample, the ratio is 10.00/4 = 2.50.

For the third sample, the ratio is 17.50/7 = 2.50.

For the fourth sample, the ratio is 25.00/10 = 2.50.

We can see that the ratio is constant at 2.50 for all the samples. This means that the relationship between the number of food samples tasted and the amount of money spent is linear, with a slope of 2.50.

Using this relationship, we can find the amount of money spent for any number of food samples tasted. For example, if someone tasted 5 food samples, we can find the amount of money spent as follows:

money spent = slope * number of food samples tasted + y-intercept

= 2.50 * 5 + 0

= 12.50

Therefore, the amount of money spent for 5 food samples would be $12.50.

Alex has $15.78 and Rick has $12.15 money.

According to the question,

We have the following information:

Alex had $3.63 more than Rick. Together they had $27.93.

Let's take the money Rick has to be $x.

Now, we have the following expression for the money Alex has:

3.63+x

Now, we have:

x+3.63+x = 27.93

2x+3.63 = 27.93

Subtracting 3.63 from both the sides:

2x = 27.93-3.63

2x = 24.3

Dividing by 2 on both the sides:

x = 24.3/2

x = $12.15

So, Rick has $12.15.

Now, the money Alex has:

3.63+12.15

$15.78

Hence, Alex has $15.78 and Rick has $12.15 money.

a(x + a) = b(b + c)

(a secant is a segment that crosses the circumference of the circle twice, and the product has to be equal for each).

Hence, replacing the values of a, b and c, we can obtain the value of x as follows:

11(11 + x) = 24.2(24.2 + 21.7)

Answer:

Assuming you want to simplify the expression, it can be shortened to:

-k² - 2k

Step-by-step explanation:

What you need to do here is called grouping like terms.  Like terms can be described as terms that have the same factors.  In this case, the factors we're looking at are k and k²:

Given:

k - 3k² -3k + 2k²

We'll rearrange to group like expressions:

= -3k² + 2k² + k -3k

Pull out common factors:

= (-3 + 2)k² + (1 - 3)k

And simplify:

= -k² - 2k

The statistical strategy that would allow the professor to determine if the average score on the final exam has gone higher is a hypothesis test. The professor can formulate a null hypothesis (H0) that the average score is still 83 and an alternative hypothesis (Ha) that the average score is greater than 83. Then the professor can collect a sample of final exam scores and calculate the sample mean.

The professor can use the sample mean and standard deviation to calculate a test statistic, which can be compared to a critical value or p-value to determine if the null hypothesis should be rejected or not.

Hypothesis testing is a commonly used statistical method to make decisions about a population based on a sample. In this case, the professor wants to determine if the average score on the final exam has increased or not. By setting up a hypothesis test, the professor can use the sample data to make an inference about the population. The null hypothesis assumes that there is no difference between the population mean and the previous average score of 83.

The alternative hypothesis assumes that the population mean has increased. By calculating a test statistic and comparing it to a critical value or p-value, the professor can make a decision to either reject or fail to reject the null hypothesis. If the null hypothesis is rejected, the professor can conclude that there is evidence to support the claim that the average score on the final exam has increased.

Given:

The expression is:

\(8x^4-2x\)

To find:

The coefficient and the exponent for each term of the given expression.

Solution:

Coefficients: In the product of s number and a variable, the number is coefficient of the variable.

Exponent: The number in the power is called exponent.

We have,

\(8x^4-2x\)

Here, the terms are \(8x^4,-2x\).

For the term \(8x^4\), the coefficient is 8 and the exponent is 4.

For the term \(-2x\), the coefficient is -2 and the exponent is 1.

Therefore, the coefficients are 8 and -2, and the exponent are 4 and 1.

Using the Poisson distribution formula as in part (i), we can calculate P(X=10 and 150 bikes arrived within an hour) and P(150 bikes arrived within an hour) independently.

(i) The probability that 20 red bikes arrive within an hour can be calculated using the Poisson distribution formula. Let X be the number of red bikes arriving within an hour, which follows a Poisson distribution with a rate of 200 * 0.05 = 10 bikes per hour (since 5% of the bikes are red). Therefore, the probability P(X=20) can be calculated as:

P(X=20) =  (e^{(-λ)} * λ²⁰) / 20!, where λ is the rate, which is 10 in this case.

Plugging in the values, we get:

P(X=20) = (e⁽⁻¹⁰⁾ * 10²⁰) / 20! ≈ 0.117

(ii) The probability that 20 red bikes arrive within the first hour and 500 bikes (of any color) arrive within the first three hours can be calculated as the product of the probabilities of these two events occurring independently.

Using the same approach as in part (i), the probability P(X=20) is 0.117.

Let Y be the number of bikes (of any color) arriving within three hours, which follows a Poisson distribution with a rate of 200 * 3 = 600 bikes. Therefore, the probability P(Y=500) can be calculated as:

P(Y=500) = (e^{(-λ)} * λ⁵⁰⁰⁰) / 500!, where λ is the rate, which is 600 in this case.

Plugging in the values, we get:

P(Y=500) = (e⁽⁻⁶⁰⁰⁰⁾ * 600⁽⁻⁵⁰⁰⁾) / 500! ≈ 0 (approximately zero, as the rate is high).

So, the probability that 20 red bikes arrive within the first hour and 500 bikes (of any color) arrive within the first three hours is approximately zero, as the event of 500 bikes arriving within three hours is highly unlikely.

(iii) Given that 20 red bikes arrived within an hour, the expected total number of bikes that arrived within this hour can be calculated as the sum of the expected number of red bikes and the expected number of bikes of other colors.

The expected number of red bikes is simply the rate of red bikes, which is 10 bikes per hour.

The expected number of bikes of other colors can be calculated by subtracting the expected number of red bikes from the total rate, which is 200 bikes per hour:

Expected number of bikes of other colors = 200 - 10 = 190 bikes per hour.

So, the expected total number of bikes that arrived within this hour is 10 + 190 = 200 bikes.

(iv) Given that 150 bikes arrived within an hour, we can use the concept of conditional probability to calculate the probability that exactly 10 out of them were red. Let X be the number of red bikes arriving within an hour, which follows a Poisson distribution with a rate of 10 bikes per hour (since 5% of the bikes are red). Therefore, the conditional probability P(X=10 | 150 bikes arrived within an hour) can be calculated as:

P(X=10 | 150 bikes arrived within an hour) = P(X=10 and 150 bikes arrived within an hour) / P(150 bikes arrived within an hour)

Using the Poisson distribution formula as in part (i), we can calculate P(X=10 and 150 bikes arrived within an hour) and P(150 bikes arrived within an hour) independently.

For P(X=10 and 150 bikes arrived within an hour), we can use the Poisson distribution formula with a rate of 10 bikes and a time interval of 1 hour:

Emily new boots cost a total of $71.4 with the tax included as 5% and the original cost of the boots being $68.

The sales tax rate in Emily's city = 5% and the cost of Emily's new boots is $68

we need to find the amount of sales tax Emily will pay for her boots,

The formula we will use =

Sale tax = Percent sales tax x Cost of the product

when we put the values in the formula, we get:

Sales tax = 5% x $68

= $3.4

now we need to also calculate the total cost for Emily's boots,

Therefore, the total cost = Cost of boots + Sales Tax

when we put the values in the formula, we get:

Total cost = $68 + $3.4

= $71.4
