Answer:

1/6

Since there are 6 faces and you're asking if 1 face is the probability, the probability is 1/6

We need to use the remainder theorem to find the remainder when the polynomial p(x) = x^4 - 9x^3 - 5x^2 - 3x + 4 is divided by the polynomial x - 3. The remainder when p(x) is divided by x - 3 is -212.

The remainder theorem states that if a polynomial f(x) is divided by x - a, then the remainder is equal to f(a).

In this case, we want to find the remainder when p(x) is divided by x - 3. To do this, we substitute x = 3 into the polynomial p(x) and calculate the result.

p(3) = (3)^4 - 9(3)^3 - 5(3)^2 - 3(3) + 4

     = 81 - 243 - 45 - 9 + 4

     = -212

Therefore, the remainder when p(x) is divided by x - 3 is -212.

Step-by-step explanation:

(a) The z-score for an age of 30 years is approximately 0.6857.

(b) The winner's age of 30 years is roughly 0.6857 standard deviations above the mean age of the winners (27.6 years), indicating they were slightly older than the average age.

(a) To transform the age of 30 years to a z-score, we use the formula:

z = (x - μ) / σ

where:

x = individual value (age of the winner) = 30 years

μ = mean age = 27.6 years

σ = standard deviation = 3.5 years

Plugging in the values, we get:

z = (30 - 27.6) / 3.5

Calculating this expression, we find:

z ≈ 0.6857

Therefore, the z-score for an age of 30 years is approximately 0.6857.

(b) Interpretation of the results:

The z-score indicates the number of standard deviations an individual value (in this case, the age of the winner) deviates from the mean. A positive z-score suggests that the individual value is above the mean.

In this context, the z-score of approximately 0.6857 means that the age of the winner (30 years) is roughly 0.6857 standard deviations above the mean age of the winners (27.6 years). This suggests that the winner in that recent year was slightly older than the average age of the tournament winners.

By using z-scores, we can compare and interpret individual values within the context of a distribution, such as the bell-shaped distribution of ages in the cycling tournament winners.

b) b) In order to decrease the MOE the sales team has to increase the sample or decrease de 99% of the CI  let´s say to 95 % but in that case

From z-table     z(c)  ≈ - 2,325    |z(c)| ≈ 2,325

CI = ( μ₀ ± z(c) * σ/√n )

Let the side of a cube be "a". The volume of the cube is "a³".

If all sides of the cube are halved, each side will now measure "a/2".Therefore, the new volume will be (a/2)³ cubic units. That is:a³ / 8 cubic units. The new volume of the cube will be reduced to 1/8 of its original volume.

Step-by-step explanation:

Her profit would amount to $4564.24 for one month which is determined by subtracting her total expenses from made revenue.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

For the month, she made a revenue of $11,449.27.

To calculate her profit, we have to subtract her total expenses from made revenue.

Her expenses were $230.21 for utilities, $2,679.82 for rent, and $3,975.00 for employee salaries which are given in the question.

Total expenses = 230.21 + 2,679.82 + 3,975.00 = 6885.03

As per the given data, the solution would be:

⇒ Total revenue - Total expenses

⇒ 11,449.27 - 11,449.27

Apply the subtraction operation, and we get

⇒ 4564.24

Therefore, her profit would amount to $4564.24 for one month.

In summary, the logistic regression models show that the demand for cigarettes is more likely to change with price for highly educated people than for lower educated individuals. The interaction between education and income in Model 2 shows that smoking rates are affected by both income and education.

To know more about the specific statistical analyses and their interpretation, it is recommended to refer to a Stata or statistical analysis guide. The provided information summarizes the steps involved in the analysis and the main findings. Running logistic regressions allows us to understand the impact of various factors on smoking behavior, considering different education and income levels. The interaction variable helps capture the combined effect of education and income on smoking rates. The interpretation of the coefficients and their significance levels provides insights into the relationship between the variables and the likelihood of smoking. Understanding these findings can contribute to understanding smoking behaviors and inform potential interventions or policies.

Answer:

Step-by-step explanation:

The area D is bounded by the lines x = 0, y = 3 – 37, and y = 3x – 3. To calculate the iterated double integral for ∫∫xdA over D, the value of the iterated double integral ∫∫xdA over the area D is 0.

To set up the iterated double integral for ∫∫xdA over D, we first need to determine the limits of integration for x and y. Looking at the given lines, x = 0 indicates that x varies from 0 to some upper limit. The line y = 3 – 37 represents a horizontal line, indicating that y has a constant value of 3 – 37, which simplifies to -34. The line y = 3x – 3 represents a slanted line with a slope of 3, indicating that y varies linearly with x.

To find the limits of integration for x, we need to determine the x-values where the slanted line and the vertical line intersect. Setting 3x – 3 equal to 0, we find x = 1. Substituting this value back into the slanted line equation, we get y = 3(1) – 3 = 0. Therefore, x varies from 0 to 1.

For y, since it has a constant value of -34, the limits of integration for y are -34 to -34.

Setting up the iterated double integral, we have ∫∫xdA = ∫[0 to 1]∫[-34 to -34] x dy dx. Integrating with respect to y first, we have ∫[0 to 1] x(-34 - (-34)) dx, which simplifies to ∫[0 to 1] 0 dx. Finally, integrating with respect to x, we get 0. Therefore, the value of the iterated double integral ∫∫xdA over the area D is 0.
