Decision Making Under Risk
A circumstance in which the implications of the chosen course of action and the likelihood that it will occur are understood is referred to as decision-making under risk . For instance, the lottery selection tasks are frequently employed to examine the nature of decision-making in risky situations.
We make the assumption that there are two or more choices and that each alternative's characteristics are explicitly specified. For each attribute, the CV (coefficient of variation) is configured in case of such decision under risks. And, since in the given question, decision maker is supposed to consider several possible outcomes for each alternative, each with a given probability of occurrence. Thus the decision made will be decision under risk.

You spend 0.88 of your allowance this week. what percent of your allowance did you spend?
Answer: 88%
Step-by-step explanation: So, to convert the decimal into a percentage, multiply .88 by 100. And BOOM! you have 88% as your answer.
We spent 88% of your allowance this week.
Since we know that,
A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
To find out what percentage of your allowance you spent,
Divide the amount you spent by your total allowance,
then multiply by 100 to get the percentage.
Here are the steps:
1. Identify the amount you spent: 0.88
2. Identify your total allowance: 1.00 (assuming your allowance is $1.00) 3. Divide the amount spent by the total allowance,
⇒ 0.88 ÷ 1.00 = 0.88 4.
Multiply the result by 100 to get the percentage,
⇒ 0.88 x 100 = 88%
Therefore, we spent 88% of your allowance this week.

The price of a new television is $423. This price includes VAT in 17 1/2%.
a) Work out the cost of the television before VAT was added.
By the end of the year, the value of a television has fallen by 12% of its value at the start of that year. The value of a television was $423 at the start of the year.
b) Work out the value of the television at the end of the third year. Give your answer to the nearest penny.
The cost of the television before VAT was added is $360 and the value of the television at the end of the third year is $288.3
What is the meaning of VAT ?VAT is an acronym for Value Added Tax. This is a tax attach to goods and products.
Given that the price of a new television is $423. This price includes VAT in 17 1/2%.
a) The cost of the television before VAT was added is calculated below.
Let the initial cost = C
(17.5 + 100)/100 x C = 423
117.5/100 x C = 423
1.175C = 423
C = 423/1.175
C = $360
b. By the end of the year, the value of a television has fallen by 12% of its value at the start of that year. If the value of a television was $423 at the start of the year, the value of the television at the end of the third year will be calculated by using the formula
A = P(1 - R%)^3
Substitute all the parameters
A = 423(1 - 12/100)^3
A = 423 x [tex]0.88^{3}[/tex]
A = 288.3 dollars

if the area of a rectangle is represented by 25x^3y^6 and its width is represented by 10xy, express the length of the rectangle in terms of x and y
The length of the rectangle in terms of x and y, given that its area is represented by 25x³y⁶ and its width is represented by 10xy is 2.5x²y⁵.
The area of a figure is the total space enclosed in two dimensions within its boundary.
The area of a rectangle is given as, area = length*width.
In the question, we are given that the area of a rectangle is represented by 25x³y⁶ and its width is represented by 10xy, and are asked to express the length of this rectangle in terms of x and y.
We know that the area of a rectangle is given as, area = length*width.
Substituting the known values in the equation, we get:
25x³y⁶ = length*10xy.
Rearranging this equation, we get:
length = 25x³y⁶/10xy = (5x²y⁵)/2 = 2.5x²y⁵.

Use properties to rewrite the given equation. Which equations have the same solution as the equation
x + + x = – x plus StartFraction 2 Over 3 EndFraction plus x equals StartFraction one-half EndFraction minus StartFraction 1 Over 5 EndFraction x.x
The equation computed shows that the correct options are A, B, and D.
How to illustrate the information?1) The equation we want to rewrite is;
³/₅x + ²/₃ + x = ¹/₂ – ¹/₅x
(³/₅ + 1)x + ²/₃ = ¹/₂ – ¹/₅x
⁸/₅x + ²/₃ = ¹/₂ – ¹/₅x
This corresponds with the solution in Option A
2) ³/₅x + ²/₃ + x = ¹/₂ – ¹/₅x
Let us use multiplication property of equality which states that if we multiply both sides of an equation by the same quantity, then both sides remain equal.
Let's get rid of the denominators by multiplying each term by the LCM of the denominators. LCM of 2,3,5 is 30. Thus;
30(³/₅x) + 30(²/₃) + 30x = 30(¹/₂) - 30(¹/₅x)
Simplifying gives;
18x + 20 + 30x = 15 - 6x
This solution corresponds with that in option B
3) We will make use of additive property of equality which states that when we add the same number to both sides of an equation, then both sides remain equal.
Let's add 6x to both sides of 18x + 20 + 30x = 15 - 6x;
18x + 20 + 30x + 6x = 15 - 6x + 6x
⇒ 24x + 30 + 20 = 15
Using subtractive property of equality, let us subtract 20 from both sides to get;
24x + 30 + 20 - 20 = 15 - 20
This corresponds with the solution in Option D.

Determine if the set (x1,x2)+(y1,y2)=(x1-x2, y1+y2) is a vector space
The set (x1,x2)+(y1,y2)=(x1-x2, y1+y2) is not a vector space.
A set is a vector space if it satisfy all the addition operation axiom and scalar multiplication axiom.
Addition operation:
Commutativity -
(x1, x2) + (y1, y2) equals (x1 - x2, y1 + y2) equals (y1, y2) + (x1, x2)
Associativity -
(x1, x2) plus ((y1, y2) plus (z1, z2)) = (x1, x2) + (z1 + y1, z2 + y2) = (x1+ y1 + z1, x2 + y2 + z2) =
((x1, x2) + (y1, y2)) + (z1, z2)
Zero element -
(0, 0) → (x1, x2) + (0, 0) = (x1, x2)
Inverse element -
(x1, x2) adding (-x1, -x2) = (0, 0)
Scalar multiplication:
Compatibility -
a(b (x, y)) = a(bx, 0) = (abx, 0) = b(ax, 0) = b(a(x, y))
Identity element -
1(x, y) = (x, 0) ≠ (x, y) [Identity element doesn’t exist for this operation.)
Distributivity law -
a((x1, x2) + (y1, y2)) = a(x1 + y1, x2 + y2) = (a(x1 + y1), 0) = a(x1, x2) + a(y1, y2)
Distributivity law -
(a + b)(x, y) = ((a + b)x, 0) = (ax, 0) + (bx, 0) = a(x, y) + b(x, y)
The scalar multiplication postulate is not fulfilled in this space (this operation does not have the identity element). It is therefore not a vector space.

a vendor sold 25 dozens of mangoes. He was able to sell 3/5 of the total number of mangoes at 15.50 pesos and the remaining at 19.00 pesos each. How much was the total sales?
Answer: 422.5
Step-by-step explanation: To find how many mangoes were sold at 15.50 pesos, find 3/5 of the total number of mangoes. 3/5 of 25 is 15 because 3 (numerator) times 25 (mangoes) divided by 5 (denominator) is 15. 15 times 15.50 (price) is 232.5 pesos. Next we take the remaining mangoes (10) and multiply it by the price (19) to get 190 pesos. Add the sales and you get 422.5 pesos.
Answer:
422.50 pesos total
Step-by-step explanation:
3/5 ths of 25 = 15
(1/5th of 25 is 5, so we can multiply that number by 3 (3)(5) to get what 3/5ths of 25 are)
So, 15 mangoes were sold at 15.50 pesos
15 × 15.50 = 232.50
(why is this multiplication?
remember that repeated addition is multiplication. We are adding the cost of each mango (15.50) 15 times, which we could write as 15.50 + 15.50... 15 times, or we could simply multiply the two values :) )
Because this vendor has sold 15 of his mangoes, he has 10 left (25 - 15 = 10), so we multiply
10 × 19.00 to find the combined cost:
10 × 19.00 = 190.00
Now, we want to find the total sale (how much money he made in total, from all 25 mangoes)
So, let's add our two values together:
232.50
+ 190.00
422. 50
So, the vendor made 422.50 pesos total from his mangoes
