{1.2.3.4.5} set builder

Step-by-step explanation:

A set-builder notation describes or defines the elements of a set instead of listing the elements. For example, the set { 1, 2, 3, 4, 5, 6, 7, 8, 9 } list the elements. The same set could be described as { x/x is a counting number less than 10 } in set-builder notation.

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

if x = 1, then the answer is 3.5
