The sequence is arithmetic and the common difference is -8.

The term number 24 is:

A(24) = -206

To check if a sequence is arithmetic, take the difference between the consecutive terms, you should get the same value for all the cases.

Here we have:

-22, -30, -38, -46, ...

The differences give:

-30 + 22 = -8

-38 + 30 = -8

-48 + 38 = -8

We get the same thing in all, so the sequence is arithmetic, and the common difference is -8.

The n-th term of this sequence will be:

A(n) = -22 + (-8)*(n - 1)

Then the 24th term is:

A(24) = -22 + (-8)*(24 - 1)= -206

The equation of the transformed exponential function g(x) is g(x) = 2^-x - 1

From the question, we have the following parameters that can be used in our computation:

Parent function: y = 2^x

The graph of the transformed exponential function g(x) passes through the points  (-2,3), (-1,1), (0,0), (1,-0.5) and (2, -0.75)

So, we have the following transformation steps:

1st Transformation:

Reflect y = 2^x across the y-axis

So, we have

y = 2^-x

2nd Transformation:

Translate y = 2^-x down by 1 unit

So, we have

y = 2^-x - 1

This means that

g(x) = 2^-x - 1

Hence, the equation of the function g(x) is g(x) = 2^-x - 1

Dana will need 8 gallons of fuel for her trip and it will cost her $35.60 in total.

To calculate the total cost of fuel for Dana's trip, we need to determine how many gallons of fuel she will need.

For the trip from New York to Boston, which is a distance of 200 miles, Dana will need 200/50 = 4 gallons of fuel.

For the return trip from Boston to New York, which is another 200 miles, Dana will also need 4 gallons of fuel.

Therefore, the total amount of fuel Dana will need for the round trip is 4 + 4 = 8 gallons.

Since biodiesel fuel costs $4.45 per gallon, the total cost of fuel for Dana's trip will be 8 x $4.45 = $35.60.

So Dana will need 8 gallons of fuel for her trip and it will cost her $35.60 in total.

The body of the loop executes two times before the condition is no longer met. So, the correct answer is:
c. 2

Let's examine the given code fragment step-by-step:

1. The variable "x" is initialized with a value of 8.
2. The "while" loop checks if the condition (x / 3) is not equal to 2. If this condition is true, the loop will execute.
3. Inside the loop, the value of "x" is decremented by 1.

Now, let's check how many times the loop will execute:

1. In the first iteration, x = 8. The condition (8 / 3) != 2 is true (2.67 != 2), so the loop executes. Then, x = 8 - 1 = 7.
2. In the second iteration, x = 7. The condition (7 / 3) != 2 is true (2.33 != 2), so the loop executes. Then, x = 7 - 1 = 6.
3. In the third iteration, x = 6. The condition (6 / 3) != 2 is false (2 == 2), so the loop does not execute any further.

To do this, we first need to standardize the value of 4.3 using the mean and standard deviation of the replacement times:

[tex]z = (x - \mu) / \sigma[/tex]

x is the value we want to standardize, μ is the mean of the distribution, and σ is the standard deviation of the distribution.

The statement "For all integers a, b, and c, if a|bc then a|b or a|c" is false, as it does not hold true for all possible choices of a, b, and c. One counterexample to this statement is (a, b, c) = (2, 3, 4).

Here, a = 2, b = 3, and c = 4.

a|bc means "a divides bc", which is true in this case since 2 divides the product of 3 and 4. However, 2 does not divide either b or c individually, so a does not divide b or c. Therefore, the statement "if a|bc then a|b or a|c" is false for this particular choice of (a, b, c).

This counterexample shows that the statement is not true for all possible choices of a, b, and c, and therefore the statement is false. It is important to note that finding a single counterexample is enough to prove the statement false.

Step-by-step explanation:

You can use trial and error by putting each set of points into the equations and seeing which one works.

All four points work for the third function, f(x) = 3x + 5.

The value of operated function is -3x²-13x+4.

Given are two functions f(x) = -x²+10x+3 and g(x) = -4x²-3x+7, we need find g(x) - f(x),

So,

g(x) - f(x) = -4x²-3x+7 - (-x²+10x+3)

= -4x²-3x+7 + x²-10x-3

The correct answer is B. P{z ≥ 1.88}.

To find the p-value for a hypothesis test, you need to determine the probability of observing a test statistic as extreme or more extreme than the one you obtained, assuming that the null hypothesis is true.

In this case, the test statistic is Z = 1.88, which represents the number of standard deviations that the sample mean is away from the hypothesized population mean of 20, under the assumption that the null hypothesis is true.

Since this is a one-tailed test in the positive direction (Ha: μ > 20), we want to find the probability of observing a Z value that is greater than or equal to the observed test statistic of 1.88.

We can use a standard normal distribution table or a calculator to find this probability, which is the p-value.

Using a standard normal distribution table or a calculator, we find that the area to the right of Z = 1.88 is 0.0307, or approximately 0.031.

Therefore, the p-value is P{z ≥ 1.88} ≈ 0.031.

Approximately 0.3% (or less) of the adult male population is taller than the average basketball player.

To approximate the percentage of the adult male population that is taller than the average basketball player using the empirical rule, we need to calculate the z-score for the average basketball player's height and determine the percentage of the population beyond that z-score.

The z-score formula is given by:

z = (x - μ) / σ

Where:

x = value (in this case, the average basketball player's height = 79 inches)

μ = mean (mean height of adult males = 70 inches)

σ = standard deviation (standard deviation of adult male heights = 3 inches)

Calculating the z-score for the average basketball player's height:

z = (79 - 70) / 3

z = 3

According to the empirical rule:

Approximately 68% of the population falls within 1 standard deviation of the mean.

Approximately 95% of the population falls within 2 standard deviations of the mean.

Approximately 99.7% of the population falls within 3 standard deviations of the mean.

Since the average basketball player's height is 3 standard deviations above the mean, we can estimate that less than 0.3% of the adult male population is taller than the average basketball player.

The differential equation dy/dx = 3x² - 2 with f(-1) = 2 is y = x³ - 2x + 1To solve this differential equation, we need to integrate both sides with respect to x.

dy/dx = 3x² - 2

Integrating both sides:

∫dy = ∫(3x² - 2)dx

y = x³ - 2x + C

Here, C is the constant of integration that we need to find. To do that, we can use the initial condition f(-1) = 2.

Substituting x = -1 and y = 2 in the equation:

2 = (-1)³ - 2(-1) + C

2 = -1 + 2 + C

C = 1

Therefore, the solution to the differential equation is:

y = x³ - 2x + 1

To overlay this solution on a slope field for the differential equation, we need to first draw the slope field. We can do this by calculating the slopes at different points in the x-y plane.

Using the differential equation, we know that the slope at any point (x, y) is given by:

dy/dx = 3x² - 2

We can draw arrows with slopes equal to 3x² - 2 at various points in the plane to get the slope field.

Once we have the slope field, we can overlay the solution y = x³ - 2x + 1 on it by plotting the curve y = x³ - 2x + 1 and checking if the direction of the curve matches the arrows in the slope field.

Overall, the solution to the differential equation dy/dx = 3x² - 2 with f(-1) = 2 is y = x³ - 2x + 1, and we can overlay this solution on the slope field to visualize the behavior of the solution at different points in the plane.

Theorem 4.3.2 states that the sum of any two rational numbers is rational. Therefore, let r and s be any two rational numbers. Then, r and s can be expressed as r = a/b and s = c/d, where a, b, c, and d are integers and b and d are not zero.

Using Theorem 4.3.2, we can conclude that r + s is also rational.

Now consider the expression[tex]3r^2 - 2r + 4[/tex]. We can express this as:

[tex]3r^2 - 2r + 4 = 3(r^2) - 2r + 4(1)[/tex]

Since [tex]r^2[/tex] is the product of two integers (r and r), it is also an integer. Using Theorem 4.3.1, we know that r is rational, and therefore [tex]3(r^2)[/tex] is the product of an integer and a rational number, making it rational.

Next, we know that -2r is the product of an integer (-2) and a rational number (r), making it rational.
