Answers

Answer 1

Answer:

What is the cardinal number of a set?

The number of distinct elements in a finite set is called its cardinal number. It is denoted as n(A) and read as ‘the number of elements of the set’.

For example:

(i) Set A = {2, 4, 5, 9, 15} has 5 elements.

Therefore, the cardinal number of set A = 5. So, it is denoted as n(A) = 5.

(ii) Set B = {w, x, y, z} has 4 elements.

Therefore, the cardinal number of set B = 4. So, it is denoted as n(B) = 4.

(iii) Set C = {Florida, New York, California} has 3 elements.

Therefore, the cardinal number of set C = 3. So, it is denoted as n(C) = 3.(iv) Set D = {3, 3, 5, 6, 7, 7, 9} has 5 element.

Therefore, the cardinal number of set D = 5. So, it is denoted as n(D) = 5.

(v) Set E = {   } has no element.

Therefore, the cardinal number of set D = 0. So, it is denoted as n(D) = 0

Step-by-step explanation:

Answer 2

Using the cardinality concept, it is found that the cardinal number of the set is of 6.

------------------------------------------------------

The cardinality of a set is given by the number of unique elements in the set.For example: set {a,a,a} has cardinality 1, as there is only one unique element, which is a.set {a,b,c} has cardinality 3, as there are three unique elements, which are a,b and c.set {a,a,b} has cardinality 2, as there are two unique elements, which are a and b.

------------------------------------------------------

set {a,b,c,d,e,f} has cardinality 6, as there are 6 unique elements, which are: a, b, c, d, e and f. Thus, the cardinal number of the set is of 6.

Question 1: 367.5 ft squared

Question 2: 21.6 miles

Step-by-step explanation:

Answer:

11. 367.5 sqft   12. 21.6 sqmiles

Step-by-step explanation:

Well for 11. if each inch is 3.5 feet then you would wan t to multiply 5 and 6 by 3.5. You get 17.5 and 21. To find area, you'll have multiply the height and width which is 17.5 and 21. Once you do that you end up with 367.5ft squared.

For 12. each inch is 4.8 mines and there are 4.5 inches. So you want to do 4.5 times 4.8 which gives you 21.6 square miles. I hope you do well.

When doing a survey you must make sure it is unbiased by asking a variety of people for example if you are wondering what is the favorite class at school you have to ask a certain amount of people from each class because if you ask only people from P.E the answer more than likely will be P.E or if u ask 3 people from Art and 17 from P.E your answer will properly be P.E.
