Step-by-step explanation:

The  coordinate of A is (-10, 10).

We have,

Point B has coordinates (2, 1).

x coordinate of A is -10.

and, distance between point A and point B is 15 units.

Using Distance Formula

d= √(-10-2)² + (y - 1)²

15² =  12² + (y-1)²

225 - 144 = (y - 1)²

(y -1)² = 81

y - 1 = 9

y = 9 + 1

y= 10

Thus, the coordinate of A is (-10, 10).

a) The system can be written as Ax = d.

b)  The system has a unique solution.

a) To rewrite the equation system in the format Ax = d, we need to arrange the coefficients of the variables in matrix A and the constants on the right-hand side in vector d. The given system of equations can be written as:

| 2  4  1 |   | p₁ |   | 77 |

| 4  3  7 | x | p₂ | = | 114 |

| 2  1  3 |   | p₃ |   | 48 |

Matrix A:

| 2  4  1 |

| 4  3  7 |

| 2  1  3 |

Vector x:

| p₁ |

| p₂ |

| p₃ |

Vector d:

| 77 |

| 114 |

| 48 |

Therefore, the system can be written as Ax = d.

b) To test the rank of the system and whether the system has a solution, we need to find the rank of matrix A. If the rank of A is equal to the rank of the augmented matrix [A | d], and the rank is equal to the number of variables (3 in this case), then the system has a unique solution. Otherwise, if the ranks are not equal or the rank is less than the number of variables, the system either has infinitely many solutions or no solution.

c) To solve the system using Gauss-Jordan elimination, we will perform row operations on the augmented matrix [A | d] until we reach row-echelon form or reduced row-echelon form. However, since the solution is not requested, I will not perform the calculations in this response.

To solve equations with fractions and variables in the denominator, we need to eliminate it by moving it to the other side. To do this, we multiply both sides of the equation by the term in the denominator. This will cancel out the fraction and leave us with a simpler equation to solve.

For example, suppose we have the equation (3 + x) / x = 2. To get rid of the fraction, we multiply both sides by x. This gives us: x * (3 + x) / x = x * 2. The x in the numerator and denominator cancel out, leaving us with:

3 + x = 2x. Now we can solve for x by subtracting x from both sides: 3 = x

This is the solution of the equation.

The expected vertical load on the foundation is  option b) 1500 PSF (pounds per square foot)

To calculate the expected vertical load on the foundation, we need to consider the weight of the concrete and the height of the wall.

The weight of the concrete can be determined using the unit weight of concrete, which is given as 150 pounds per cubic foot (PCF). Since the wall is 10 feet tall, we can calculate the weight of the concrete per square foot of the wall.

Weight of concrete per square foot = unit weight of concrete * height of the wall

Weight of concrete per square foot = 150 PCF * 10 feet = 1500 pounds per square foot (PSF)

Therefore, the expected vertical load on the foundation is 1500 PSF (option b).

This means that for every square foot of the foundation, it is expected to bear a load of 1500 pounds due to the weight of the poured concrete.

It is important to note that factors such as soil conditions, additional loads, and structural considerations may influence the actual load on the foundation. It is recommended to consult with a structural engineer for precise calculations and design requirements.

An exact equation that represent the polynomial function is p(x) = -2(x + 2)(x - 2)(x - 1).

Based on the graph of this polynomial, we can logically deduce that it has a zero of multiplicity 1 at x = -2, a zero of multiplicity 1 at x = 2, and zero of multiplicity 1 at x = 1;

x = -2 ⇒ x - 2 = 0.

(x - 2)

x = 2 ⇒ x + 2 = 0.

(x + 2)

x = 1 ⇒ x - 1 = 0.

(x - 1)

In this context, an exact equation that represent the polynomial function is given by:

p(x) = a(x + 2)(x - 2)(x - 1)

By evaluating and solving for the leading coefficient "a" in this polynomial function based on the y-intercept (0, -8), we have;

-8 = a(0 + 2)(0 - 2)(0 - 1)

-8 = a4

a = -8/4.

a = -2

Therefore, the required polynomial function is given by:

p(x) = -2(x + 2)(x - 2)(x - 1)

The study is most likely attempting to establish is Criterion validity and the study featured a(n) scale of measurement is Ordinal scale.

10). The study is most likely attempting to establish is: By criterion validity.

Criterion validity measures how well one measure predicts the outcome for another measure.

Here, we are judging how well the scores on the employment test predict the performance of the person.

Nominal Scale: This scale is used to assign labels to variables that have no numerical values.

For eg : Gender (male and female) , colour (brown blue black white)

Ordinal scale: It matters how the values are arranged, but it makes no difference how much they differ.

For eg: 1: Food applications rated from 1 to 5, 5 being the best. If a app is rated as 2 and other is rated as 4 does not mean the later is twice as good as the first.

Interval scale: An interval scale is a numerical scale where the order and size of the difference between the numbers are known. Absolute zero does not indicate absence in an interval scale, it only means there is no value.

For eg: Temperature in degree Celsius. If T1=5o Celsius  and T2=15o Celsius this means is a temperature difference of 10o , but with T3=0o does not mean there is no temperature.

Ratio scale: The ratio scale is another numerical scale where the order and size of the difference between the values are known, and where absolute zero denotes the absence of values.

For eg: Salary of people

11). The study featured a(n)scale of measurement is: By ordinal scale

We will rank the chairs on a scale where order counts and the size of the difference is not particularly significant.

Hence, for 10th the option A is correct and for 11th the option B is correct.

Answer:

Step-by-step explanation:

a) It is not necessarily rational to decide to run in unfavorable conditions solely because a large entry fee has been paid. Rationality is determined by weighing the expected benefits and costs of an action, considering factors such as personal safety and enjoyment.

a) Rational decision-making involves assessing the expected benefits and costs of an action and choosing the option that maximizes personal utility. In the case of running in adverse weather conditions, factors such as personal safety, physical well-being, and enjoyment of the experience should be considered alongside the sunk cost of the entry fee. While the entry fee represents a financial investment, it should not be the sole determinant of the decision. If the expected negative consequences of running in dangerous conditions outweigh the benefits derived from participating, it would be rational to prioritize personal well-being over the sunk cost of the fee.

b) Skipping the free beer after the race can be rational if the perceived benefits of having the beer are outweighed by other factors, such as the time and effort required to wait in line or the desire to prioritize other post-run activities.

b) Rationality, as defined by economists, takes into account the subjective preferences and trade-offs individuals make based on their utility. While the free beer may have a positive utility for you after a long run, skipping it can still be rational. The decision depends on the relative value you assign to different activities or opportunities available to you at that moment. Factors such as the length of the line, time constraints, and alternative options for post-run relaxation or recovery could influence your decision. If the perceived benefits of waiting in line for the free beer are outweighed by other activities or priorities, it would be rational to skip it and allocate your time and effort elsewhere. Rationality in this context involves optimizing overall utility based on personal preferences and circumstances.

X = 6

because 8 - 2 = 6

The expression representing the situation is 3x + 2y, and when we substitute x = 5 and y = 8 into the expression, we find that Gabe scored a total of 31 points in the basketball game.

We are given that Gabe made 5 three-pointers and 8 two-point shots. To calculate the total points scored by Gabe, we multiply the number of three-pointers by 3 (since each three-pointer is worth 3 points) and the number of two-point shots by 2 (since each two-point shot is worth 2 points). Then, we sum these two products to get the total points.

Using the expression 3x + 2y, where x represents the number of three-pointers and y represents the number of two-point shots, we substitute x = 5 and y = 8 into the expression:

3(5) + 2(8) = 15 + 16 = 31

The area under the normal probability density function (p.d.f.) within 1.96 standard deviations of the mean on both sides is approximately 0.95.

In a normal distribution, the area under the p.d.f. curve represents probabilities. The area between the mean and 1.96 standard deviations to the left or right represents approximately 95% of the data. Since the normal distribution is symmetrical, we can split this area equally on both sides, resulting in approximately 0.475 (or 47.5%) on each side.

To calculate the total area, we add up the areas on both sides: 0.475 + 0.475 = 0.95. This means that 95% of the data falls within the range of 1.96 standard deviations from the mean. Consequently, the remaining 5% is distributed outside this range (2.5% to the left and 2.5% to the right). Therefore, the correct answer is A. 0.05, which corresponds to the area outside the range of 1.96 standard deviations from the mean.

The rate at which the volume of the cone is changing is -5235.98 inches³/s when the radius of the circular cone is 50 inches and the height is 10 inches.

The formula for the circular cone can be given as;

V = 1/3 πr²h

Now we take the derivative with respect to time as follows;

V = 1/3 πr²h

dV/dt = 1/3π d/dt(r²h)

dV/dt = 1/3π [2r(dr/dt) × h + r²(dh/dt)]

Now we substitute the values in this equation as follows;

dV/dt = 1/3π [2 × 50 × 5 × 10 + (50²) (-4)]

dV/dt = 1/3π [ 5000 - 10000]

dV/dt = 1/3π [-5000]

dV/dt = -5235.98

Graphing is done here. Pick three values for x and put them in a table to graph the equation.

All of the points in the plane of the form (x, f(x)) make up a function f's graph. The graph of the equation y = f might also be used to define the graph of f. (x). Because of this, the graph of a function is a particular instance of the graph of an equation.

Plotting points first, then tracing a line across them, is the first method. Using the slope and y-intercept is the second method.

Select three x values and list them in a table to graph the equation. (Tip: choose values that are simple to calculate, such as 1, 0 and 1).
