Answer:
<h3>12</h3>
Step-by-step explanation:
The cardinal number of a set is the number of element in the set. Given the set A = {{3, 5, 7, ... 25}}, you can see that the elements of the set are odd numbers from 3 to 25. Writing out the full set;
A = {{3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25}}
Counting the total number of element in the set, you will see that there are only 12 elements in the set. Hence the cardinal number of the set is 12 i.e n(A) = 12
Answer:
a
Step-by-step explanation:
a = 3
b = 2
divide by -3, change the sign:
(a-b) > 0
a always has to be greater than be to be true
The mean is the average.
To find the mean, you add up all the numbers, and then divide by the number of numbers.
