1.What must be used to tell if a collection of items is a set?
Mnenie [13.5K]
1. A set is described either by listing all its elements between braces { } (the listing method), or by enclosing a rule within braces that determines the elements of the set (the rule method).
Example: So if P(x) is a statement about x, then S = { x | P ( x )} means “S is the set of all x such that P(x) is true.”

2. Types of set:
• Empty, or null, set {∅}.
• finite sets
• infinite set.

3. An infinite set: The set whose elements cannot be listed, i.e., set containing never-ending elements. Example: Set of all points in a plane.

4. The union of two given sets is the smallest set which contains all the elements of both the sets. To find the union of two given sets A and B is a set which consists of all the elements of A and all the elements of B such that no element is repeated. The symbol for denoting union of sets is ‘∪’.

The union of sets A and B, denoted by A ∪ B, is the set of elements formed by combining all the elements of A and all the elements of B into one set.

Now all you have to do is divide 6 by 6 and the answer to that is 1.

Example: 6 ÷ 6 = 1

x + 0.05s = 120
Solve for x and s

The interval for u with 90% is 
x - 0.10s

A vehicle covers a distance of 37.8km in 1.4 liters
tamaranim1 [39]
Hopes this helps:

Answer: 27 km


Distance covered by the vehicle in 1 l of petrol = 37.8/1.4 (We have took 1.4 on the other side)
= 378/14 (decimal would be eliminated by decimal)
= 27 km
