(3) The question state that we should explain the relationship between angle ACB and A'C'B' in the given diagram.
From the the diagram in the question, we can see that wa have two different triangle which are ABC and A'B'C'.
The relationship between angle ACB and angle A'C'B' is that they are corresponding angles. because they are on the same side of the line.
Corresponding angles are any pair of angles each of which is on the same side of one of two lines cut by a trasnsversal and on the same side of the transversal.
Therefore, the relationship between angle ACB and angle A'C'B' is that they are corresponding angles.
Very nice handwriting but the math and English are confusing.
Let's assume we're told

The subscript is important.
I think we're told the similar sum with 11 gives the smallest possible value for the sum. This is a rather cagey way of telling us 11 is the mean of the nine points. The mean is the number which minimizes the sum of squared deviations.


If 11 is the mean, the sum of the points is 9(11)=99.

Answer: 1080
Answer:
40
Step-by-step explanation:
20 ÷ 1/2 = 20 * 2 = 40 half liters in 20 liters
Answer:
single-channel, multi -phase
Step-by-step explanation:
The concept known as '' Queuing'' is not only important in the mathematical aspect alone but it is also useful in economic matters as signifies the abundance of resources that is when we have queues it means the reason for it is that the available resources is not enough.
From the question above we have that there are 3 individual car wash stalls, it is also given that the customers wait in a single line before choosing the next available stall. This means that there is only a single-channel.
Then, we have that from the single line initially, the queues then moves to multi -phase that is to 3 individual car wash stalls.
