n(A) = 26
Solution:
Let us first define the cardinal number of the set.
Cardinal number of the set:
The number of distinct elements in a finite set is called its cardinal number. It is denoted as n(A).
Given set: A = {a, b, c, .... z}
We know that, there are 26 elements in the alphabet "a to z".
Number of elements in the set A = 26
Hence n(A) = 26.
Answer: 8.5%
7/82=0.0853
Multiply by 100 to get percentage
0.0853 x 100 = 8.53
X= 180
now you have to multiply all them with 180
5(180)= 900
2(180)= 360
Collect like terms
2n2 i’m gonna assume is 2n^2
and n2 is 2n
2n^2-10n+5
B
