1. List out the factors of each number:

12: 1, 2, 3, 4, 6, 12

18: 1, 2, 3, 6, 9, 18

48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

2. Find the common factors of all three numbers:

1, 2, 3, 6

3. The greatest number of these common factors is 6, so 6 is the HCF of 12, 18, and 48.

The Highest Common Factor (HCF) is the greatest number that can be evenly divided into all the numbers in a set. To find the HCF of a set of numbers, we must first list out the factors for each number. The factors are the numbers that can be evenly divided into the original number. For instance, 1, 2, 3, 4, 6, and 12 are the factors of 12. We then compare the lists of factors of all the numbers and find the common factors. The greatest number of these common factors is the HCF. For example, the HCF of 12, 18, and 48 is 6, because 6 is the greatest number that can be evenly divided into all three numbers without leaving a remainder

Decision Analysis is a mathematical method for making decisions in uncertain environment.

What is environment ?

Environment refers to the surrounding conditions, resources and factors that can have an impact on an organism, community, or system. This can include physical factors such as weather, terrain, and pollution, as well as biological factors such as other living organisms, and social or economic factors such as culture, laws and economic conditions.

The process of Decision Analysis can be broken down into several steps:

1) Define the decision problem: Clearly state the problem and the decision maker's objectives.

2) Identify the decision alternatives: List all the feasible options available to the decision maker.

3) Specify the probability distribution of the uncertain parameters: Assign probabilities to the possible outcomes of the uncertain parameters.

4) Evaluate the expected value or expected loss for each alternative: Compute the expected value or expected loss for each alternative, using the probability distribution of the uncertain parameters.

5) Choose the alternative with the highest expected value or the lowest expected loss: Select the alternative that maximizes the expected value or minimizes the expected loss.

6) Sensitivity analysis: Check the robustness of the decision by studying the effect of small changes in the model's assumptions.

There are 12 possible seating arrangement that Ali, Bonnie, Carlo, and Dianna can seat in a 4 seated car while visiting to a nearby theme park.

There are in total 4 people so the the possible seating arrangement should be 4! = 4*3*2 = 24.

But only 2 people know how to drive a car that is Bonnie and Carlo,

So the remaining seat can be occupied by any three that are remaining beside the driver.

So 3 remaining people can go in the front passenger seat.

There are 2 people who can go in the first back passenger seat.

The remaining person must go in the last seat.

Thus, there are 2x3x2 or 12 ways that they can be seated.

The slower vehicle travels 178 of the total 380 km at an average speed of 89 km/h.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are separated by the 'equal' sign. A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

Here,

Let x and x+12 be the speed of cars.

2(x+x+12)=380

2x+12=190

2x=178

x=89 km/hour

x+12=89+12

=101 km/hour

The rate of the slower car is 89 km/hour and it travels 178 km out of 380 km.

Explanation:

x = number of minutes

y = temperature

The equation is

y = 23x+68

The slope 23 tells us how fast the oven is heating up. The 68 is the y intercept, and it's the starting temperature (when x = 0).

We want to find the value of x when y = 275

y = 23x+68

275 = 23x+68

275-68 = 23x

207 = 23x

23x = 207

x = 207/23

x = 9

It takes   9  minutes   for the oven to reach a temperature of 275°F

--------

Check:

y = 23x+68

y = 23*9+68

y = 207+68

y = 275

the volume of a cone will be 201.06 in³.

What is volume of cone?

The area or volume that a cone takes up is referred to as its volume. Cones are measured by their volume in cubic units such as cm3, m3, in3, etc. By rotating a triangle at any of its vertices, a cone can be created. A cone is a robust, spherical, three-dimensional geometric figure.. Its surface area is curved. The perpendicular height is measured from base to vertex. Right circular cones and oblique cones are two different types of cones. While the vertex of an oblique cone is not vertically above the center of the base, it is in the right circular cone where it is vertically above the base.

So the

V = (1/3)πr²h.

Given, data r = 5yards

h = 8 yards

Volume = 1/3 * π * r ²* h

V = 1/3 * π * 4 ²* 12 =201.06 in³.

Hence, the volume of a cone will be 201.06 in³.

It will take 15 minutes to run 2.5 miles at an average speed of 10 miles per hour.

speed is described as. the pace at which an object's location changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it just has a direction and no magnitude.

Given, you run at an average speed of 10 mi/h.

Since,

Average speed = 10 mi/h

or in minutes

Average speed = 10/60 = 1/6 miles per minutes

Thus,

to run 2.5 miles it will take:

time = distance/ speed

time taken to run 2.5 miles = 2.5 * 6 =15 minutes

The nearest multiple of 100 to 350 is 400.

We must determine the smallest value of x that comes the closest to the specified number n given two values, n and x. We must identify a k such that x*k is most similar to n. If we use k = n/x, we may not get the maximum value of k. By comparing the values of floor(n/x)*x and ceil(n/x)*x, we may get the nearest.

Rounding off numbers are discussed here, where we need to round a number. Rounding can be done for every place value of a number.

the function value f(14) = 4.8.

What is a function?

A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function if one were mapped to a single value instead. Additionally, output values can be equal to input values.

The x-values are input into the function machine. The function machine then performs its operations and outputs the y-values. The function within can be any function.

f(1)= 10

f(21)= 2

Let the function f(x) = ax+b

f(1)= 10 = a+b

f(21)= 2 = 21a +b

The coordinates of the image of point E after a translation 2 units down are (-4, -1).

The coordinates of the image of point F after a translation 2 units down are (-3, -4).

The coordinates of the image of point G after a translation 2 units down are (2, -1).

To translate coordinates in a two-dimensional plane, you need to know the translation vector. A translation vector is a pair of numbers (a, b) that indicates the amount of movement in the x-direction and y-direction.

To translate a point (x, y) by the translation vector (a, b), you can use the following formulas:

x' = x + a

y' = y + b

Where x' and y' are the new coordinates of the point after the translation.

A translation is a transformation that moves a figure a certain distance in a certain direction without rotating or reflecting it. In this case, we are asked to translate the triangle EFG 2 units down. This means that we need to move the triangle down 2 units on the y-axis.

To translate a point (x, y) down 2 units, we can add -2 to the y-coordinate. The new coordinates of the point will be (x, y - 2).

The coordinates of E are (-4, 1), so the coordinates of E' after the translation are (-4, 1-2) = (-4,-1)

The coordinates of F are (-3,-2), so the coordinates of F' after the translation are (-3,-2-2) = (-3,-4)

The coordinates of G are (2, 1), so the coordinates of G' after the translation are (2,1-2) = (2,-1)

So the new coordinates for the triangle EFG' after the translation are:

E'(-4,-1)

F'(-3,-4)

G'(2,-1)

It's important to notice that the x-coordinates didn't change because we are only translating the triangle down, on the y-axis.

No, 3 is not an algebraic expression.

In mathematics, an algebraic expression is a combination of numbers, variables and arithmetic operations (such as addition, subtraction, multiplication and division) that can be evaluated to a specific value when the variables are assigned specific numerical values.

For example, 3x + 2 is an algebraic expression. Here, x is the variable and 3, 2 are constants. We can substitute any numerical value for x and evaluate the expression for that specific value.

On the other hand, 3 is a numerical value, not an expression. It doesn't contain any variables or operators that can be evaluated for different values. It is a constant value, it doesn't change with the change of x or any other variable.

In summary, an algebraic expression is a combination of numbers, variables and arithmetic operations, whereas 3 is just a numerical value, not an algebraic expression.
