In this problem, we are given that {Xn}nz1 is a supermartingale, and we need to prove that Yn = min(X₁, M) is also a supermartingale, where M is a constant.

To prove that Yn is a supermartingale, we need to show that it satisfies the supermartingale property: E[Yn+1 | Y₁, Y₂, ..., Yn] ≤ Yn.

First, let's consider Yn+1:

Yn+1 = min(X₁, M) -- (1)

Now, let's consider the conditional expectation E[Yn+1 | Y₁, Y₂, ..., Yn]:

E[Yn+1 | Y₁, Y₂, ..., Yn] = E[min(X₁, M) | Y₁, Y₂, ..., Yn] -- (2)

Since {Xn}nz1 is a supermartingale, we know that E[Xn+1 | X₁, X₂, ..., Xn] ≤ Xn for all n.

Using this property, we can rewrite Equation (2) as:

E[Yn+1 | Y₁, Y₂, ..., Yn] = E[min(X₁, M) | Y₁, Y₂, ..., Yn] ≤ min(E[X₁ | Y₁, Y₂, ..., Yn], M) -- (3)

Now, let's analyze the two cases separately:

Case 1: If Yn < M, then Yn+1 = min(X₁, M) = Yn. In this case, Equation (3) becomes:

E[Yn+1 | Y₁, Y₂, ..., Yn] ≤ min(E[X₁ | Y₁, Y₂, ..., Yn], M) ≤ min(E[X₁ | Y₁, Y₂, ..., Yn], Yn) -- (4)

Since Yn ≤ Xn for all n, we have:

min(E[X₁ | Y₁, Y₂, ..., Yn], Yn) ≤ min(E[X₁ | Y₁, Y₂, ..., Yn], Xn) -- (5)

Since {Xn}nz1 is a supermartingale, we know that E[Xn+1 | X₁, X₂, ..., Xn] ≤ Xn for all n. Combining this with Equation (5), we get:

min(E[X₁ | Y₁, Y₂, ..., Yn], Xn) ≤ Xn -- (6)

By substituting Equation (6) into Equation (5), we have:

min(E[X₁ | Y₁, Y₂, ..., Yn], Yn) ≤ Xn -- (7)

Since Yn = min(X₁, M) = X₁ if X₁ ≤ M and Yn = min(X₁, M) = M if X₁ > M, we can rewrite Equation (7) as:

E[Yn+1 | Y₁, Y₂, ..., Yn] ≤ Yn -- (8)

Case 2: If Yn = M, then Yn+1 = min(X₁, M) = M. In this case, Equation (3) becomes:

E[Yn+1 | Y₁, Y₂, ..., Yn] ≤ min(E[X₁ | Y₁, Y₂, ..., Yn], M) = M -- (9)

Since Yn+1 = Yn = M, we have:

E[Yn+1 | Y₁, Y₂, ..., Yn] ≤ Yn+1 -- (10)

The selection depends on individual needs, preferences, and the intended use of the tiny house.

a) To find the amount of space inside each house, we need to calculate the volume for each design.

House on the left:

Volume = length x width x height = 2.5 m x 18 m x 2.8 m = 126 m³

Triangular house:

Volume of a triangular prism = (base area x height) / 2

Base area = (1/2) x base x height = (1/2) x 4 m x 10 m = 20 m²

Volume = (20 m² x 7 m) / 2 = 70 m³

b) When comparing the environmental impacts of each house, several factors need to be considered:

Positive impacts:

1. Material usage: Tiny houses use fewer materials, reducing resource consumption and waste generation.

2. Energy efficiency: Smaller living spaces require less energy for heating, cooling, and lighting, leading to lower energy consumption.

3. Land utilization: Tiny houses can be built on smaller plots of land, preserving green spaces and reducing urban sprawl.

Negative impacts:

1. Construction materials: Although tiny houses use less material overall, the environmental impact depends on the types of materials used. Sustainable and eco-friendly materials should be prioritized.

2. Water and waste management: Adequate provisions for water supply and waste disposal should be implemented to minimize environmental impacts.

3. Transportation: The transportation of tiny houses to their locations can contribute to carbon emissions if not done efficiently.

c) The choice of design for a tiny house depends on personal preferences and priorities. However, considering the provided information:

The house on the left offers a larger interior space of 126 m³, providing more room for living and storage. It may be suitable for individuals or couples who desire more space and functionality within their tiny house.

The triangular house has a smaller interior volume of 70 m³ but offers a unique design and aesthetic appeal. It may be preferred by individuals who prioritize a distinctive architectural style or who are looking for a minimalist and cozy living space.

Ultimately, the selection depends on individual needs, preferences, and the intended use of the tiny house. Factors such as lifestyle, desired amenities, and personal values regarding sustainability and resource conservation should be considered when making the final decision.

5.94 minutes is the half-life, or the amount of time it takes to half the substance to degrade (about 6 minutes).

When we use the formula A = A0(1 - r)t,

(1/2)A₀ = A₀(1 - 0.11)t

[Divide both sides by A₀ results in:

1/2 = (0.87)t

Using the log of both sides;:

log(1/2) = log(0.87)t

Using a logarithm property, we can bring the "t" to the front, giving us:

The best loan option for Azizah would be to choose the loan from PUBLICA Bank as it has a lower total cost.

To determine the best loan option, we need to compare the total cost of each loan from MYBOK BANK and PUBLICA Bank. Let's calculate the total cost for each loan option:

Loan Option 1: MYBOK BANK

Term of loan: 8 years

No deposit required

Interest rate: 6%

Total Cost = Car Price + Insurance + Road Tax + Total Interest

Car Price = RM140,000

Insurance + Road Tax = RM5,300

Total Interest = (Car Price + Insurance + Road Tax) * (Interest Rate / 100) * Term of loan

Total Interest = (140,000 + 5,300) * (6 / 100) * 8 = RM67,440

Total Cost = 140,000 + 5,300 + 67,440 = RM212,740

Loan Option 2: PUBLICA Bank

Term of loan: 6 years

Deposit: 20% of the car price

Interest rate: 4.5%

Total Cost = (Car Price - Deposit) + Insurance + Road Tax + Total Interest

Deposit = 20% of RM140,000 = RM28,000

Car Price - Deposit = RM140,000 - RM28,000 = RM112,000

Insurance + Road Tax = RM5,300

Total Interest = (Car Price - Deposit + Insurance + Road Tax) * (Interest Rate / 100) * Term of loan

Total Interest = (112,000 + 5,300) * (4.5 / 100) * 6 = RM37,260

Total Cost = 112,000 + 5,300 + 37,260 = RM154,560

Based on the calculations, the total cost for the loan from MYBOK BANK is RM212,740, while the total cost for the loan from PUBLICA Bank is RM154,560. Therefore, the best loan option for Azizah would be to choose the loan from PUBLICA Bank as it has a lower total cost.

The calculation and record the answer with the correct number of significant figures. The final answer is 0.3724, accurate to four significant figures.

When performing calculations with significant figures, it is important to consider the precision of the numbers involved. In this case, we are adding 34.123 and 1.70, which gives us 35.823. The subtraction of 2.565 from 98.7654 gives us 96.1994.

To find the final result, we divide 35.823 by 96.1994, resulting in 0.372352. However, we must round the answer to the appropriate number of significant figures. Since 2.565 has the least number of significant figures (four), we round our answer to four significant figures as well.

Performing the calculation, we have:

(34.123 + 1.70) = 35.823

(98.7654 - 2.565) = 96.1994

Dividing the sum by the difference, we get:

35.823 / 96.1994 = 0.372352

Considering significant figures, we look at the least precise number, which is 2.565, with four significant figures. Therefore, our final answer should also have four significant figures.
