The numbers on the second die are \(0, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6.\)

Given that,

The sum of the two numbers will be \(1, 2, ..., 12\) with an equal probability of \(\dfrac{1}{12}\) each.

For the numbers on the second die, determine a set of numbers that, when combined with the numbers on the first die, will result in an equal probability for each possible sum from 1 to 12.

Let's analyze the possible sums and their corresponding combinations of numbers from the two dice:

Sum 1: The only combination that results in a sum of 1 is (1, 1).

Therefore, the second die should have a side with 1.

Sum 2: The combinations that result in a sum of 2 are (1, 1) and (2, 0).

Since we already have 1 on the second die, the other number should be 1.

Hence, the second die should have a side with 1 and a side with 0.

Sum 3: The combinations that result in a sum of 3 are (1, 2) and (2, 1).

Since we already have 1 on the second die, the other number should be 2.

Hence, the second die should have a side with 1 and a side with 2.

Following this pattern, determine the numbers on the second die as:

Sum 1: 1

Sum 2: 0, 1

Sum 3: 1, 2

Sum 4: 1, 3

Sum 5: 2, 3

Sum 6: 2, 4

Sum 7: 3, 4

Sum 8: 3, 5

Sum 9: 4, 5

Sum 10: 4, 6

Sum 11: 5, 6

Sum 12: 6

Thus, The numbers on the second die are \(0, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6.\)

The estimated value of f(b) using linear approximation is -24.44, and the error in the approximation is approximately 24.54.

Given, f(x) = 1/x^(1/2)We have to use linear approximation to estimate δf for a change in x from x = a to x = b, and then use the estimate to approximate f(b), and find the error using the calculator

.To find the δf using the linear approximation, we have to first find the first derivative of the function and then use it in the formula.

Differentiating f(x) w.r.t x, we get:f'(x) = -1/2x^(3/2)

Now, using the formula for linear approximation, we have:δf ≈ f'(a) * δxδx = b - a

Now, substituting the values, we get:δf ≈ f'(a) * δxδx = b - a = 107 - 100 = 7Thus,δf ≈ f'(100) * 7f'(100) = -1/2 * 100^(3/2)δf ≈ -35 * 7δf ≈ -245

To approximate f(b), we have:f(b) ≈ f(a) + δff(a) = f(100) = 1/100^(1/2)f(b) ≈ f(a) + δf = 1/100^(1/2) - 245 ≈ -24.44

To find the error, we can use the actual value of f(b) and the estimated value of f(b) that we found above:

Actual value of f(b) is:f(107) = 1/107^(1/2) ≈ 0.0948Thus, the error is given by: Error = |f(b) - Approximation|Error = |0.0948 - (-24.44)| ≈ 24.54

N is congruent to k+1 modulo 3, and since k+1 is not divisible by 3, N is not divisible by 3. Hence, we have shown that if the sum of the digits of a natural number is divisible by 3, then the number itself is not divisible by 3. This can be answered by the concept of Polynomial.

Suppose we have a natural number N = d_k * 10^k + d_{k-1} * 10^{k-1} + … + d_1 * 10 + d_0, where each d_i is a digit between 0 and 9 inclusive, and k is the number of digits in N minus 1. We can recognize N as the evaluation of the polynomial f(x) = d_k * x^k + d_{k-1} * x^{k-1} + ... + d_1 * x + d_0, evaluated at x = 10. Note that f(x) has integer coefficients and degree k, and thus satisfies the conditions of the theorem.

For example, let's consider a natural number N represented as a polynomial f(x) = a_nx^n + a_(n-1)x^(n-1) + … + a_0. To determine if N is divisible by 3, we can check if f(a) ≡ f(b) (mod 3) for integer values of a and b. Similarly, to determine if N is divisible by 9, we can check if f(a) ≡ f(b) (mod 9) for integer values of a and b. Using this theorem, we can deduce divisibility criteria for natural numbers by 3 or 9.

Now, suppose the sum of the digits of N is divisible by 3. Then we can write N = 3m for some integer m. Note that 10 is congruent to 1 modulo 3, so by the theorem, we have f(10) is congruent to f(1) modulo 3. But f(10) = N and f(1) = k+1, since the sum of the coefficients of f(x) is equal to k+1.

Therefore, N is congruent to k+1 modulo 3, and since k+1 is not divisible by 3, N is not divisible by 3. Hence, we have shown that if the sum of the digits of a natural number is divisible by 3, then the number itself is not divisible by 3.

linear functions (or lines) have really only 2 attributes :

the slope (indicating the inclination of the line).

the y-intercept (the intersection with the y-axis) or the x-intercept. either way, they show the actual position of the line.

the lines intersect at one point, if they have different slopes.

they intersect at infinitely many points, if the slope and the y- or x-intercepts are equal (ultimately that means the lines are identical, so every point is an intersection point).

if they have the same slope but different y- or x-intercepts, it means they are parallel and will never intersect.

Step-by-step explanation:

The linear function represented by the table is:

y = 8x + 6

A general linear function can be written in slope-intercept form as:

y = a*x + b

Where a is the slope and b is the y-intercept.

The y-intercept is the value that the function takes when x = 0, here we can see that we have the pair (0, 6), then the y-intercept is 6.

y = a*x + 6

Now we want to find the value of a. Using any other of the pairs in the table (like (3, 30) for example)

We can replace the points in the equation and then solve it for a.

Using the second point (1, 14) we will get:

14 = a*1 + 6

Now we can solve that for a.

14 = a + 6

14 - 6 = a

b) The number of ways to form a committee of 6 people with an equal number of men and women is 54,600.

c) The number of ways to form a committee of 6 people with more women than men is 91,455.

a) To form a committee of 6 people from the department, we can choose 6 individuals from a total of 25 people (10 men + 15 women). The order in which the committee members are chosen does not matter, and we are not concerned with any specific positions within the committee. Therefore, we can use the concept of combinations.

The number of ways to choose 6 people from a group of 25 is given by the combination formula:

C(25, 6) = 25! / (6! * (25 - 6)!) = 25! / (6! * 19!) = 177,100

Therefore, there are 177,100 ways to form a committee of 6 people from the department.

b) In this case, we need to choose an equal number of men and women for the committee. We can select 3 men from the available 10 men and 3 women from the available 15 women. Again, the order of selection does not matter.

The number of ways to choose 3 men from 10 is given by the combination formula:

C(10, 3) = 10! / (3! * (10 - 3)!) = 10! / (3! * 7!) = 120

Similarly, the number of ways to choose 3 women from 15 is:

C(15, 3) = 15! / (3! * (15 - 3)!) = 15! / (3! * 12!) = 455

To find the total number of ways to form a committee with an equal number of men and women, we multiply these two combinations:

Total = C(10, 3) * C(15, 3) = 120 * 455 = 54,600

Therefore, there are 54,600 ways to form a committee of 6 people with an equal number of men and women.

c) In this case, we need to form a committee with more women than men. We can choose 1 or 2 men from the 10 available men and select the remaining 6 - (1 or 2) = 5 or 4 women from the 15 available women.

For 1 man and 5 women:

Number of ways to choose 1 man from 10: C(10, 1) = 10

Number of ways to choose 5 women from 15: C(15, 5) = 3,003

For 2 men and 4 women:

Number of ways to choose 2 men from 10: C(10, 2) = 45

Number of ways to choose 4 women from 15: C(15, 4) = 1,365

The total number of ways to form a committee with more women than men is the sum of these two cases:

Total = (Number of ways for 1 man and 5 women) + (Number of ways for 2 men and 4 women)

     = 10 * 3,003 + 45 * 1,365

     = 30,030 + 61,425

the point on the line y = 2x + 3 that is closest to the origin is (-6/5, 3/5).

To find the point on the line y = 2x + 3 that is closest to the origin, we need to minimize the distance between the origin (0, 0) and a point (x, y) on the line.

The distance between two points (x1, y1) and (x2, y2) is given by the distance formula:

d = √[\((x2 - x1)^2 + (y2 - y1)^2\)]

In our case, the point on the line y = 2x + 3 can be represented as (x, 2x + 3). So, the distance between the origin (0, 0) and this point is:

d = √[\((x - 0)^2 + ((2x + 3) - 0)^2\)]

  = √[\(x^2 + (2x + 3)^2\)]

  = √[\(x^2 + (4x^2 + 12x + 9\))]

  = √[\(5x^2 + 12x + 9\)]

To minimize this distance, we can minimize the square of the distance, which is easier to work with. So, we will minimize:

f(x) =\(5x^2 + 12x + 9\)

To find the minimum of this quadratic function, we can take the derivative with respect to x and set it equal to zero:

f'(x) = 10x + 12

10x + 12 = 0

10x = -12

x = -12/10

x = -6/5

Now that we have the x-coordinate of the point, we can substitute it back into the equation y = 2x + 3 to find the y-coordinate:

y = 2(-6/5) + 3

y = -12/5 + 3

y = -12/5 + 15/5

y = 3/5

under the restrictions that c is negative to ensure strict concavity, the utility function u(w) = -(b - w)c displays increasing absolute risk aversion.

To ensure that u(w) is strictly increasing, we need the derivative of u(w) with respect to w to be positive for all values of w. Taking the derivative, we have du(w)/dw = -c. For u(w) to be strictly increasing, -c must be positive, which implies c must be negative.

To ensure that u(w) is strictly concave, we need the second derivative of u(w) with respect to w to be negative for all values of w. Taking the second derivative, we have d²u(w)/dw² = 0. Since the second derivative is constant and negative, u(w) is strictly concave.

Now, let's examine the concept of increasing absolute risk aversion. If a utility function u(w) exhibits increasing absolute risk aversion, it means that as wealth (w) increases, the individual becomes more risk-averse.

In the given utility function u(w) = -(b - w)c, when c is negative (as required for strict concavity), the absolute risk aversion increases as wealth (w) increases. This is because the negative sign implies that the utility function is concave, indicating that the individual becomes more risk-averse as wealth increases.
