A motorist is using the AHP to choose a new car from three possible models Arrow, a Bestmobile and a Commuter. The choice will a

ttributes, Cost and Style. The motorist considers that Cost is "weakly more than Style. When asked to compare the cost of the cars, the motorist makes the following statements: On cost, the Bestmobile is 'weakly preferred' to the Arrow, but the Arrow is "weakly preferred' to the Commuter Also, the Bestmobile is 'extremely preferred' to the Commuter. On style, the Arrow is 'very strongly preferred' to the Bestmobile, but the Commuter is 'weakly preferred' to the Arrow. Also, the Commuter is 'extremely preferred' to the Bestmobile

Why would a designer choose to use an isometric sketch rather than a perspective sketch to share their idea with a design team m
alexdok [17]

Designers use both isometric and perspective sketches to maintain an object’s visual proportions. Isometric sketches are 3D objects drawn with lines that have no vanishing points while perspective sketches are 3D objects drawn with one or more vanishing points.

Designers choose to use an isometric sketch because it is more accurate than perspective drawings and makes the design look more professional. Isometric sketches are much easier to handle because the length of each measure is same as the plan. This is especially for designers drawing pictures by hand. It is time saving and you do not need to calculate the angle of every edge.

wlad13 [49]

Answer:

  1. def check_subset(l1, l2):
  2.    status = False
  3.    count = 0
  4.    if(len(l1) > len(l2)):
  5.        for x in l2:
  6.            for y in l1:
  7.                if x == y:
  8.                    count += 1
  9.        if(count == len(l2)):
  10.            return True  
  11.        else:
  12.            return False
  13.    else:
  14.        for x in l1:
  15.            for y in l2:
  16.                if x==y:
  17.                    count += 1
  18.        if(count == len(l1)):
  19.            return True  
  20.        else:
  21.            return False
  22. print(check_subset([1,4,6], [1,2,3,4,5,6]))
  23. print(check_subset([2,5,7,9,8], [7,8]))
  24. print(check_subset([1, 5, 7], [1,4,6,78,12]))

Explanation:

The key idea of this solution is to create a count variable to track the number of the elements in a shorter list whose value can be found in another longer list.

Firstly, we need to check which list is shorter (Line 4). If the list 2 is shorter, we need to traverse through the list 2 in an outer loop (Line 5) and then create another inner loop to traverse through the longer list 1 (Line 6).  If the current x value from list 2 is matched any value in list 1, increment the count variable by 1. After finishing the outer loop and inner loop, we shall be able to get the total count of elements in list 2 which can also be found in list 1. If the count is equal to the length of list 2, it means all elements in the list 2 are found in the list 1 and therefore it is a subset of list 1 and return true (Line 10-11) otherwise return false.

The similar process is applied to the situation where the list 1 is shorter than list 2 (Line 15-24)

If we test our function using three pairs of input lists (Line 26-28), we shall get the output as follows:

True

True

False
