Answer:
Option (A)
Step-by-step explanation:
A set of real numbers is a combination of both rational and irrational numbers.
But the elements in the sets of rational and irrational numbers will be different.
In short, rational and irrational number sets are the two subsets of real numbers.
Hence, the number is an element of either the set of rational numbers or the set of irrational numbers.
Option (A) is the correct option.

Perimeter = 2L + 2W
42= 2L + 2(8)
26 = 2L
13 = L
Answer:
a)
Step-by-step explanation:
The article reported that only 26% of american adults ate 3 or more servings of vegetables per day. We don't know if the subjects were asked how many servings per day they consume (in this case the variable would be quantitative since they would answer with a number) or if they were asked if they ate 3 or more servings per day (in this case the variable would be categorical since they would answer with a yes or no)
Answer:
2200
Step-by-step explanation:
4.5% × ? = 99
? =
99 ÷ 4.5% =
99 ÷ (4.5 ÷ 100) =
(100 × 99) ÷ 4.5 =
9,900 ÷ 4.5 =
2,200
