The sequence diverges and the the limit to the expression  is[tex]lim(n- > \infty) a_n = \infty - 1 = \infty[/tex]

To determine the convergence of the sequence, we can simplify the expression for the nth term and then apply the limit laws.

[tex]a_n = n - \sqrt(n + n^2) * \sqrt(n + 3)[/tex]

simplify the term under the square root as follows

[tex]\sqrt(n + n^2) * \sqrt(n + 3) = \sqrt(n*(1+n)) * \sqrt(n+3) \\= \sqrt(n) * \sqrt(n+1) * \sqrt(n+3)[/tex]

Substitute this back into the original expression for [tex]a_n[/tex]

[tex]a_n = n - \sqrt(n) * \sqrt(n+1) * \sqrt(n+3)[/tex]

Now, use the limit laws to evaluate the limit as n approaches infinity.

[tex]a_n = n - \sqrt(n) * \sqrt(n+1) * \sqrt(n+3) * ((\sqrt(n+1) * \sqrt(n+3)) / (\sqrt(n+1) * \sqrt(n+3)))\\= n - \sqrt(n^2 + 4n + 3) / (\sqrt(n+1) * \sqrt(n+3))\\= n - [(n+1)^2 - 1]^(1/2) / [(n+1)*(n+3)]^(1/2)[/tex]

Now, we can apply the limit laws:

[tex]lim(n- > \infty) n = \inftylim(n- > \infty) [(n+1)^2 - 1]^(1/2) / [(n+1)(n+3)]^(1/2) = 1/\sqrt(11) = 1[/tex]

Therefore, the limit of the sequence is[tex]lim(n- > \infty) a_n = \infty - 1 = \infty[/tex]

Since the limit of [tex]a_n[/tex] as n approaches infinity is infinity, the sequence diverges.

The work done by the force is found to be  254 J.

Given,F = 4i - 8j + 9k

Initial position of object = (0, 6, 4)

Final position of object = (4, 14, 18)

The work done by the force to move the object from initial position to final position is calculated using the formula:

W = F · d

where F is the force and d is the displacement or distance traveled by the object along a straight line from initial position to final position.

In order to find displacement vector d, we need to find the difference between final and initial positions.

That is,

d = (4i - 8j + 9k) - (0i + 6j + 4k)  = 4i - 14j + 14k

Therefore, the displacement vector is

d = 4i - 14j + 14k.

To find the work done, we need to calculate the dot product of F and d.

That is,

W = F · d

= (4i - 8j + 9k) · (4i - 14j + 14k)

= (4 * 4) + (-8 * -14) + (9 * 14)

The volume of the solid generated is found as: 32π/3.

To find the volume of the solid generated by revolving the region bounded by the graphs of y=x² and y=2x about the line x=−1

using the Washer method, the following steps are to be followed:

Step 1: Identify the region being rotated

First, we should sketch the graph of the region that is being rotated. In this case, we are revolving the region bounded by the graphs of y=x² and y=2x about the line x=−1.

Therefore, we have to find the points of intersection of the two graphs as follows:

x² = 2x

⇒ x² - 2x = 0

⇒ x(x - 2) = 0

⇒ x = 0 or x = 2

Since x = −1 is the axis of rotation, we should subtract 1 from the x-values of the points of intersection.

Therefore, we get the following two points for the region being rotated: (−1, 1) and (1, 2).

Step 2: Find the radius of the washer

We can now find the radius of the washer as the perpendicular distance between the line of rotation and the curve. The curve of rotation in this case is y=2x and the line of rotation is x=−1.

Therefore, the radius of the washer can be given by:

r = (2x+1) − (−1) = 2x+2.

Step 3: Find the height of the washer

The height of the washer is given by the difference between the two curves:

height = ytop − ybottom.

Therefore, the height of the washer can be given by:

height = 2x − x².

Step 4: Set up and evaluate the integral

The volume of the solid generated is given by the integral of the washer cross-sectional areas:

V = ∫[2, 0] π(2x+2)² − π(2x+2 − x²)² dx

= π ∫[2, 0] [(2x+2)² − (2x+2 − x²)²] dx

= π ∫[2, 0] [8x² − 8x³] dx

= π [(2/3)x³ − 2x⁴] [2, 0]

= 32π/3.

Next, we can use axiom 2, which states that AA = B. Applying this axiom, we can rewrite (AB)X as (AA)BX.

Now, let's apply axiom 4, which states that if X is a symbol, then BX = X. We can replace BX with X, giving us (AA)X.

Using axiom 5, which states that if X = Y and Y = Z, then X = Z, we can simplify (AA)X to AX.

The `M_PI` constant is used from the `math.h` library to convert between degrees and radians. The `%lf` format specifier is used with `scanf` to read double precision floating-point values.

To calculate the magnitude and direction of the resultant vector obtained by adding two vectors, you can use the following C code:

```c

#include <stdio.h>

#include <math.h>

void add_vectors(double mag1, double dir1, double mag2, double dir2, double *res_mag, double *res_dir) {

   double x1 = mag1 * cos(dir1 * M_PI / 180.0);  // Convert degrees to radians

   double y1 = mag1 * sin(dir1 * M_PI / 180.0);

   double x2 = mag2 * cos(dir2 * M_PI / 180.0);

   double y2 = mag2 * sin(dir2 * M_PI / 180.0);

   double res_x = x1 + x2;

   double res_y = y1 + y2;

   *res_mag = sqrt(res_x * res_x + res_y * res_y);  // Calculate magnitude using Pythagorean theorem

   *res_dir = atan2(res_y, res_x) * 180.0 / M_PI;  // Convert radians to degrees

}

int main() {

   double mag1, dir1, mag2, dir2, res_mag, res_dir;

   printf("Enter the magnitude and direction of the first vector (separated by a space): ");

   scanf("%lf %lf", &mag1, &dir1);

   printf("Enter the magnitude and direction of the second vector (separated by a space): ");

   scanf("%lf %lf", &mag2, &dir2);

   add_vectors(mag1, dir1, mag2, dir2, &res_mag, &res_dir);

   printf("The magnitude of the resultant vector is %.5f\n", res_mag);

   printf("The direction of the resultant vector is %.5f\n", res_dir);

   return 0;

}

```

This code defines a function `add_vectors` that takes the magnitudes and directions of two vectors as input, and calculates the magnitude and direction of the resultant vector. It then uses the `scanf` function to read the inputs from the user, calls the `add_vectors` function, and finally prints the calculated magnitude and direction of the resultant vector.

The `add_vectors` function performs vector addition by converting the magnitudes and directions into Cartesian coordinates. It then adds the corresponding components, calculates the magnitude using the Pythagorean theorem, and determines the direction using the `atan2` function. The results are stored in the variables pointed to by `res_mag` and `res_dir`.

Jean Ackyroyd and Sue Bathgate will be earning the same salary after 6 years, which is equivalent to 12 semi-annual raises.

To determine after how many years Jean Ackyroyd and Sue Bathgate will be earning the same salary, we can set up an equation based on their starting salaries and semi-annual raises.

Let's denote the number of semi-annual raises as "n" (the same for both women). The total salary for Jean Ackyroyd after "n" raises can be represented as:

Total salary for Jean Ackyroyd = Starting salary + (Number of raises * Raise amount)

                             = $18,000 + (n × $750)

Similarly, the total salary for Sue Bathgate after "n" raises can be represented as:

Total salary for Sue Bathgate = Starting salary + (Number of raises × Raise amount)

                           = $16,200 + (n × $900)

To find the number of years when they will be earning the same salary, we can set these two equations equal to each other and solve for "n":

$18,000 + (n × $750) = $16,200 + (n × $900)

Simplifying the equation:

$18,000 - $16,200 = (n × $900) - (n × $750)

$1,800 = n × $150

Dividing both sides by $150:

n = $1,800 / $150

n = 12

Therefore, after 12 semi-annual raises (which corresponds to 6 years since there are two raises per year), Jean Ackyroyd and Sue Bathgate will be earning the same salary.

The image vertex B' after rotating B(1, 0) by 180° counterclockwise is B'(-1, 0).

To determine the image vertices of B' after rotating the polygon 180° counterclockwise, we need to apply the rotation transformation to the original coordinates.

The rotation of a point (x, y) counterclockwise by 180° can be achieved by multiplying the coordinates by the rotation matrix:

R = [cos(180°) -sin(180°)]

[sin(180°) cos(180°)]

The cosine and sine of 180° are -1 and 0, respectively.

Therefore, the rotation matrix becomes:

R = [-1 0]

[ 0 -1]

Now, let's apply this rotation matrix to the coordinates of point B(1, 0):

B' = R * B

= [-1 0] * [1]

[0]

Multiplying the matrices, we get:

B' = [(-1)(1) + (0)(0)]

[(0)(1) + (-1)(0)]

Simplifying, we find:

B' = [-1]

[0]

Thus, the image vertex B' after rotating B(1, 0) by 180° counterclockwise is B'(-1, 0).

To determine the image vertices of the other vertices A, C, and D, you can follow the same process and apply the rotation matrix to their corresponding coordinates.

Answer:

They are not mutually exclusive

Step-by-step explanation:

Let A be the event of getting a sum of 6 on dice.

Let B be the events of getting doubles .

A={ (1,5), (2,4), (3,3), (4,2), (5,1) }

B = { (1,1) , (2,2), (3,3),  (4,4), (5,5), (6,6) }

Since we know that Mutaullty exclusive events are those when there is no common event between two events.

i.e. there is empty set of intersection.

But we can see that there is one element which is common i.e. (3,3).

At x = -1, m = -5At x = 0, m = 8At x = 1, m = -5

Given function is, f(x) = 8 - 3x - 2x²

Derivative of f(x) will be, f'(x) = -3 - 4x

Slopes of the tangent lines can be calculated as below:

At x = -1, m = f'(-1) = -3 - 4(-1)

= -3 + 4 = 1At x = 0, m = f'(0)

= -3 - 4(0) = -3 = 3

At x = 1, m = f'(1) = -3 - 4(1)

= -3 - 4 = -7

Hence, the slopes of the tangent lines at x = -1, x = 0, and x = 1 are -5, 8, and -5 respectively.

The derivative of a function provides us with the slope of the tangent at any point on the graph. To find the derivative of the given function, we need to differentiate it.

In this case, we have to apply the power rule and the constant multiple rule to find the derivative. Therefore, the derivative of the given function is f'(x) = -3 - 4x.

Now, we need to find the slopes of the tangent lines at x = -1, x = 0, and x = 1 by substituting the respective values of x in the derivative of the function.  

At x = -1, m = f'(-1) = -3 - 4(-1) = -3 + 4 = 1.

This means that the slope of the tangent line at x = -1 is 1.  At x = 0, m = f'(0) = -3 - 4(0) = -3 = 3.

This means that the slope of the tangent line at x = 0 is 3.  At x = 1, m = f'(1) = -3 - 4(1) = -3 - 4 = -7.

This means that the slope of the tangent line at x = 1 is -7.

To standardize a normal distribution, we must subtract the mean and divide by the standard deviation. This transforms the data to a distribution with a mean of zero and a standard deviation of one.

In this case, we have a normal distribution with a mean of 100 and a standard deviation of 100, which we want to standardize.We can use the formula:Z = (X - μ) / σwhere X is the value we want to standardize, μ is the mean, and σ is the standard deviation. In our case, X = 100, μ = 100, and σ = 100.

Substituting these values, we get:Z = (100 - 100) / 100 = 0Therefore, standardizing a N(100,100) distribution would result in a standard normal distribution with a mean of zero and a standard deviation of one.

When it comes to probability, standardization is a critical tool. In probability, standardization is the method of taking data that is on different scales and standardizing it to a common scale, making it easier to compare. A standardized normal distribution is a normal distribution with a mean of zero and a standard deviation of one.The standardization of a normal distribution N(100,100) is shown here. We can use the Z-score method to standardize any normal distribution. When the mean and standard deviation of a distribution are known, the Z-score formula may be used to determine the Z-score for any data value in the distribution.

Z = (X - μ) / σWhere X is the value we want to standardize, μ is the mean of the distribution, and σ is the standard deviation of the distribution.

When we use this equation to standardize the N(100,100) distribution, we get a standard normal distribution with a mean of 0 and a standard deviation of 1.The standard normal distribution is vital in statistical analysis. It allows us to compare and analyze data that is on different scales. We can use the standard normal distribution to calculate probabilities of events happening in a population. To calculate a Z-score, we take the original data value and subtract it from the mean of the distribution, then divide that by the standard deviation. When we standardize the N(100,100) distribution, we can use this formula to calculate Z-scores and analyze data.

To standardize a N(100,100) distribution, we subtract the mean and divide by the standard deviation, which results in a standard normal distribution with a mean of zero and a standard deviation of one.

a) Given r(t) = (cost, sint), for this vector, we need to compute the unit tangent vector T(t) at t=π/4.

We know that r(t) is a 2-dimensional vector function.

To find the unit tangent vector at any point, we can use the formula: T(t) = r'(t) / |r'(t)|

To compute r'(t), we differentiate r(t) using the chain rule:r'(t) = (-sint, cost)The magnitude of r'(t) is given by the square root of the sum of squares of its components:|r'(t)| = √(sint² + cost²)

= 1,

since sin²t + cos²t = 1 for all t.

So, T(π/4) = r'(π/4) / |r'(π/4)

|= (-sin(π/4),

cos(π/4)) / 1

= (-1/√2, 1/√2)

b) Given r(t) = (t², t³), for this vector, we need to compute the unit tangent vector T(t) at t=5.

Using the same formula, we can find T(t) as: T(t) = r'(t) / |r'(t)|Differentiating r(t),

we get:r'(t) = (2t, 3t²)

Therefore, at t=5,T(5)

= r'(5) / |r'(5)|= (10, 75) / √(10² + 75²)

c) Given r(t) = e^ti + e^(-5t)j + tk, for this vector, we need to compute the unit tangent vector T(t) at t=-4.

Using the same formula, we can find T(t) as: T(t) = r'(t) / |r'(t)|Differentiating r(t), we get: r'(t) = ie^ti - 5e^(-5t)j + k

Therefore, at t=-4,T(-4)

= r'(-4) / |r'(-4)|

= (-ie^(-4i) + 5e^(20)j + k) / √(1 + 25e^(-40))

Therefore, T(-4) = (-ie^(-4i) + 5e^(20)j + k) / √(26.013)

Therefore, T(-4) = (-ie^(-4i) + 5e^(20)j + k) / 5.100, to 3 decimal places.

The estimates for **Bo** and **B1** for the relationship between **MPG.highway** (y) and **EngineSize** (x) are as follows:

- **Bo**: 35.1535

- **B1**: -3.5340

These estimates indicate the intercept (Bo) and the slope (B1) of the linear regression model that relates the highway miles per gallon (MPG) to the engine size. The value of Bo (35.1535) represents the expected MPG.highway when the engine size (x) is zero, which may not have a practical interpretation in this context. On the other hand, the value of B1 (-3.5340) indicates the change in MPG.highway for every one-unit increase in the engine size. A negative value suggests that larger engine sizes are associated with lower highway MPG.

The predicted number of situps for a person who watches 13.5 hours of TV is approximately 14.8 situps (rounded to one decimal place).

To predict the number of situps a person who watches 13.5 hours of TV can do, we can use the regression equation:

y = ax + b

where y is the number of situps and x is the number of hours of TV watched.

Given:

a = -1.176

b = 30.7

Substituting the values into the regression equation, we have:

y = -1.176x + 30.7

To predict the number of situps for 13.5 hours of TV watched, we substitute x = 13.5 into the equation:

y = -1.176(13.5) + 30.7

Calculating this expression:

y = -15.876 + 30.7

y = 14.824

Therefore, the predicted number of situps for a person who watches 13.5 hours of TV is approximately 14.8 situps (rounded to one decimal place).

The equations of the tangents to the curve y = sin(x) - cos(x) parallel to x + y - 1 = 0 are y = -x - 1 + 7π/4 and y = -x + 1 + 3π/4.

To find the equations of the tangents to the curve y = sin(x) - cos(x) that are parallel to the line x + y - 1 = 0, we first need to find the slope of the line. The given line has a slope of -1. Since the tangents to the curve are parallel to this line, their slopes must also be -1.

To find the points on the curve where the tangents have a slope of -1, we need to solve the equation dy/dx = -1. Taking the derivative of y = sin(x) - cos(x), we get dy/dx = cos(x) + sin(x). Setting this equal to -1, we have cos(x) + sin(x) = -1.

Solving the equation cos(x) + sin(x) = -1 gives us two solutions: x = 7π/4 and x = 3π/4. Substituting these values into the original equation, we find the corresponding y-values.

Thus, the equations of the tangents to the curve that are parallel to the line x + y - 1 = 0 are:

1. Tangent at (7π/4, -√2) with slope -1: y = -x - 1 + 7π/4

2. Tangent at (3π/4, √2) with slope -1: y = -x + 1 + 3π/4

The given equation is 7x4+2x3−9x2+2x−6=0 and we need to determine the possible number of positive real zeros and the possible number of negative real zeros for the function.

Since the highest power of x is 4, there are a maximum of 4 possible real zeros. Using Descartes' Rule of Signs, we can find the maximum number of positive and negative real zeros. To find the number of positive zeros, we count the sign changes in the function starting with the leftmost term: From 7x4 to 2x3, there is 1 sign change. From 2x3 to −9x2, there is 1 sign change. From −9x2 to 2x, there is 1 sign change. From 2x to −6, there is 1 sign change. Therefore, there is a maximum of 1 positive real zero.

From 2x to −6, there is 1 sign change. Therefore, there is a maximum of 1 negative real zero. The maximum possible number of real zeros for a polynomial function is given by the degree of the polynomial function. If we talk about the given polynomial function then it has degree 4, so it has a maximum of 4 possible real zeros. Descartes' Rule of Signs is a method to count the possible number of positive or negative real zeros of a polynomial function. According to this rule, the number of positive zeros of a polynomial is equal to the number of sign changes in the coefficients of the terms or less than that by an even integer, i.e., 0, 2, 4, etc. The number of negative zeros of a polynomial is equal to the number of sign changes in the coefficients of the terms when replaced by (-x) in the polynomial function.

Answer:

The surface area of a triangular prism can be calculated using the formula:

Surface Area = 2(Area of Base) + (Perimeter of Base) x (Height of Prism)

where the base of the triangular prism is a triangle and its height is the distance between the two parallel bases.

Given the measurements of the triangular prism as 10 cm, 6 cm, 8 cm, and 14 cm, we can find the surface area as follows:

- The base of the triangular prism is a triangle, so we need to find its area. Using the formula for the area of a triangle, we get:

Area of Base = (1/2) x Base x Height

where Base = 10 cm and Height = 6 cm (since the height of the triangle is perpendicular to the base). Plugging in these values, we get:

Area of Base = (1/2) x 10 cm x 6 cm = 30 cm^2

- The perimeter of the base can be found by adding up the lengths of the three sides of the triangle. Using the given measurements, we get:

Perimeter of Base = 10 cm + 6 cm + 8 cm = 24 cm

- The height of the prism is given as 14 cm.

Now we can plug in the values we found into the formula for surface area and get:

Surface Area = 2(Area of Base) + (Perimeter of Base) x (Height of Prism)

Surface Area = 2(30 cm^2) + (24 cm) x (14 cm)

Surface Area = 60 cm^2 + 336 cm^2

Surface Area = 396 cm^2

Therefore, the surface area of the triangular prism is 396 cm^2.

A limit refers to a numerical quantity that defines how much an independent variable can approach a particular value before it's not considered to be approaching that value anymore.

A limit is said to exist if the function value approaches the same value for both the left and the right sides of the given x-value. In other words, it is said that a limit exists when a function approaches a single value at that point. However, a limit can be said not to exist if the left and the right-hand limits do not approach the same value.Examples: When the limits did exist:lim x→2(x² − 1)/(x − 1) = 3lim x→∞(2x² + 5)/(x² + 3) = 2When the limits did not exist: lim x→2(1/x)lim x→3 (1 / (x - 3))

As can be seen from the above examples, when taking the limit as x approaches 2, the first two examples' left-hand and right-hand limits approach the same value while in the last two examples, the left and right-hand limits do not approach the same value for a limit at that point to exist.

The formula for the number of ways to distribute `m` distinguishable balls into `n` distinguishable urns is: C(m + n - 1, n - 1)

The formula for the number of ways to distribute `m` distinguishable balls into `n` distinguishable urns is:

C(m + n - 1, n - 1)

where C(n, k) represents the binomial coefficient, also known as "n choose k".

In this case, the formula becomes:

C(m + n - 1, n - 1)

This formula accounts for the fact that we can think of placing `m` balls and `n-1` dividers (or "bars") in a line, and the number of ways to arrange them represents the distribution of balls into urns.

The m + n - 1 represents the total number of spaces in the line (balls + dividers), and choosing n-1 spaces to place the dividers separates the line into n sections, corresponding to the urns.

The minimum-cost Sum-of-Products (SOP) form for the function [tex]\(f(x_1, x_2, x_3) = m(1, 2, 3, 5)\)[/tex] is [tex]\(f(x_1, x_2, x_3) = x_1'x_2'x_3 + x_1x_2'x_3' + x_1x_2x_3'\)[/tex]. The minimum-cost Product-of-Sums (POS) form for the same function is [tex]\(f(x_1, x_2, x_3) = (x_1 + x_2 + x_3')(x_1' + x_2 + x_3)(x_1' + x_2' + x_3)\)[/tex].

To find the minimum-cost SOP form, we start by identifying the minterms covered by the function, which are m(1, 2, 3, 5). From these minterms, we observe the patterns of variables that appear and do not appear in each minterm. Based on this observation, we can write the SOP form [tex]\(f(x_1, x_2, x_3) = x_1'x_2'x_3 + x_1x_2'x_3' + x_1x_2x_3'\)[/tex], where the terms represent the combinations of variables that result in the desired function output.

On the other hand, to obtain the minimum-cost POS form, we start by identifying the max terms covered by the function, which are M(0, 4, 6, 7) (complements of the minterms). We observe the patterns of variables that appear and do not appear in each maxterm and form the POS expression by taking the complements of these patterns. Therefore, the POS form is

[tex]\(f(x_1, x_2, x_3) = (x_1 + x_2 + x_3')(x_1' + x_2 + x_3)(x_1' + x_2' + x_3)\)[/tex]

where the terms represent the combinations of variables that result in the complement of the desired function output.

Both the SOP and POS forms represent equivalent logic expressions for the given function, but the minimum-cost forms are optimized to require the fewest number of gates or circuits to implement, resulting in more efficient circuit designs.

Therefore, the solution to the quadratic inequality [tex]x^2 - x[/tex] >= 42 can be represented on a number line and in interval notation as: (-∞, -6] U [7, +∞).

To solve the quadratic inequality [tex]x^2 - x[/tex]>= 42, we can start by moving all the terms to one side of the inequality to form a quadratic expression:

[tex]x^2 - x - 42[/tex] >= 0

Next, we can factor the quadratic expression:

(x - 7)(x + 6) >= 0

Now we can determine the critical points by setting each factor equal to  zero and solving for x:

x - 7 = 0 --> x = 7

x + 6 = 0 --> x = -6

These critical points divide the number line into three intervals: (-∞, -6),(-6, 7), and (7, +∞).

To determine the sign of the expression (x - 7)(x + 6) in each interval, we can choose a test point from each interval and substitute it into the expression.

For the interval (-∞, -6), let's choose x = -10:

(-10 - 7)(-10 + 6) = (-17)(-4) = 68 > 0

For the interval (-6, 7), let's choose x = 0:

(0 - 7)(0 + 6) = (-7)(6) = -42 < 0

For the interval (7, +∞), let's choose x = 10:

(10 - 7)(10 + 6) = (3)(16) = 48 > 0

Based on these test results, we can determine the sign of the expression as follows:

In the interval (-∞, -6), the expression is positive (+).

In the interval (-6, 7), the expression is negative (-).

In the interval (7, +∞), the expression is positive (+)

If people prefer a choice with risk to one with uncertainty, they are said to be averse to uncertainty.

Uncertainty and risk are related concepts in decision-making under conditions of incomplete information. However, they represent different types of situations.

- Risk refers to situations where the probabilities of different outcomes are known or can be estimated. In other words, the decision-maker has some level of knowledge about the possible outcomes and their associated probabilities. When people are averse to risk, it means they prefer choices with known probabilities and are willing to take on risks as long as the probabilities are quantifiable.

- Uncertainty, on the other hand, refers to situations where the probabilities of different outcomes are unknown or cannot be estimated. The decision-maker lacks sufficient information to assign probabilities to different outcomes. When people are averse to uncertainty, it means they prefer choices with known risks (where probabilities are quantifiable) rather than choices with unknown or ambiguous probabilities.

In summary, if individuals show a preference for choices with known risks over choices with uncertain or ambiguous probabilities, they are considered averse to uncertainty.

If people prefer a choice with risk to one with uncertainty, they are said to be averse to uncertainty.
