The divergence of the vector field F is positive for y > -1/3 and negative for y <  -1/3.

To plot the vector field F(x, y) = (xy, x + y^2), we can first visualize the vectors at various points in the xy-plane. Let's choose a range of values for x and y and calculate the corresponding vectors. We'll use a step size of 1 for simplicity.

Here is a sample grid of points and their corresponding vectors:

(x, y) = (-2, -2) -> F(-2, -2) = (4, 2)

(x, y) = (-1, -2) -> F(-1, -2) = (2, 2)

(x, y) = (0, -2) -> F(0, -2) = (0, 2)

(x, y) = (1, -2) -> F(1, -2) = (0, 2)

(x, y) = (2, -2) -> F(2, -2) = (4, 2)

(x, y) = (-2, -1) -> F(-2, -1) = (2, 1)

(x, y) = (-1, -1) -> F(-1, -1) = (1, 1)

(x, y) = (0, -1) -> F(0, -1) = (0, 1)

(x, y) = (1, -1) -> F(1, -1) = (0, 1)

(x, y) = (2, -1) -> F(2, -1) = (2, 1)

... and so on for other values of y and for positive values of y.

To calculate the divergence (divF) of the vector field, we need to find the partial derivatives of the components of F with respect to x and y. Then we sum these partial derivatives.

F(x, y) = (xy, x + y^2)

∂F/∂x = y

∂F/∂y = 1 + 2y

divF = ∂F/∂x + ∂F/∂y = y + (1 + 2y) = 3y + 1

Now, we can analyze where the divergence is positive (divF > 0) and where it is negative (divF < 0).

For divF > 0:

If y > -1/3, then divF > 0.

For divF < 0:

If y < -1/3, then divF < 0.

B. 2 and OD. 15 are not possible lengths for the third side of the triangle.

To determine the possible values for the length of the third side of a triangle, we need to consider the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Given that two sides have lengths 6 and 9, we can analyze the possibilities:

6 + 9 > x

x > 15 - The sum of the two known sides is greater than any possible third side.

6 + x > 9

x > 3 - The length of the unknown side must be greater than the difference between the two known sides.

9 + x > 6

x > -3 - Since the length of a side cannot be negative, this inequality is always satisfied.

Based on the analysis, the possible values for the length of the third side are:

A. 7

C. 4

□E. 10

O F. 12

B. 2 and OD. 15 are not possible lengths for the third side of the triangle.

b)  there are 100,800 different license plates possible with 2 vowels followed by 4 digits, assuming letters and digits cannot be repeated.

To calculate the number of different license plates with 2 vowels followed by 4 digits, where letters and digits cannot be repeated, we need to consider the possibilities for each position.

Let's break down the calculation step by step:

1. Vowels: Since we need 2 vowels in the license plate, we need to consider the number of choices for each vowel position. There are 5 vowels in the English alphabet (A, E, I, O, U).

  - For the first vowel position, we have 5 choices.

  - For the second vowel position, we have 4 choices remaining (after using one vowel in the first position).

  Therefore, the number of possibilities for the vowel positions is 5 * 4 = 20.

2. Digits: Since we need 4 digits in the license plate, we need to consider the number of choices for each digit position. There are 10 digits (0-9).

  - For the first digit position, we have 10 choices.

  - For the second digit position, we have 9 choices remaining (after using one digit in the first position).

  - For the third digit position, we have 8 choices remaining.

  - For the fourth digit position, we have 7 choices remaining.

  Therefore, the number of possibilities for the digit positions is 10 * 9 * 8 * 7 = 5,040.

3. Combining the possibilities: To obtain the total number of possible license plates, we multiply the number of possibilities for the vowel positions by the number of possibilities for the digit positions:

  Total possibilities = 20 (vowels) * 5,040 (digits) = 100,800.

The reflexive closure of r is {(a, b) ∣ a ≠ b} ∪ {(a, a) ∣ a ∈ integers}.

The reflexive closure of a relation is the smallest reflexive relation that contains the original relation. In this case, the original relation is {(a, b) ∣ a ≠ b} on the set of integers.

To find the reflexive closure, we need to add pairs (a, a) for every element a in the set of integers that is not already in the relation. Since a ≠ a is false for all integers, we need to add all pairs (a, a) to make the relation reflexive.

Therefore, the reflexive closure of r is {(a, b) ∣ a ≠ b} ∪ {(a, a) ∣ a ∈ integers}. This reflexive closure ensures that for every element a in the set of integers, there is a pair (a, a) in the relation, making it reflexive.

Answer: 69

Step-by-step explanation:

There is a significant relationship between the number of cats she owns and the number of times an old widow was married (r = +0.91, p < 0.05, r² = 0.82).

Given, the Pearson correlation coefficient of +0.91,

There appears to be a strong +ve correlation between the number of cats she owns and the number of times an old widow was married.

It suggests that the more times a widow was married,the more cats she tends to own.

Approximately 82% of the variance in the number of cats owned can be explained by the number of times a widow was married is indicated by the coefficient of determination (r²).

Hence, we can say that there is a significant relationship between the number of cats she owns and the number of times an old widow was married (r = +0.91, p < 0.05, r² = 0.82).

The number of 4-letter words that can be formed without any condition imposed is 8,064.

To determine the number of 4-letter words that can be formed without any conditions, we can use the concept of permutations. Since we have 8 options (a, b, c, d, e, f, g) for each letter position, we can multiply the number of options for each position to find the total number of possibilities.

For the first letter position, we have 8 options to choose from. Similarly, for the second, third, and fourth positions, we also have 8 options each. Therefore, the total number of possibilities is:

8 options for the first position × 8 options for the second position × 8 options for the third position × 8 options for the fourth position = 8 × 8 × 8 × 8 = 8,064.

Hence, there are 8,064 possible 4-letter words that can be formed without any conditions imposed.

(a) The probability that a randomly selected policyholder lives more than 80 years is approximately 0.3106.  (b) Given that a male policyholder just turned 80, the probability that he will live for at least three more years is approximately 0.6166.

(a) To find the probability that a randomly selected policyholder lives more than 80 years, we need to calculate the cumulative probability of survival beyond 80 for both males and females separately, and then weigh them based on the gender distribution.

For males: Using the normal distribution with mean 75 and standard deviation 8, we find the probability of survival beyond 80 is approximately 0.3446.

For females: Using the normal distribution with mean 78 and standard deviation 6, we find the probability of survival beyond 80 is approximately 0.2847.

The weighted probability for a randomly selected policyholder is (0.60 * 0.3446) + (0.40 * 0.2847) = 0.3106.

(b) Given that a male policyholder just turned 80 years old today, we can use conditional probability to calculate the likelihood of him living for at least three more years.

Using the normal distribution with mean 75 and standard deviation 8, the probability of survival beyond 83 (80 + 3) is approximately 0.8621.

Therefore, the probability that a male policyholder, who just turned 80, will live for at least three more years is 0.8621.
