Answer:
n(A) = 3
n(B) = 6
-6 ∈ A => True
-14 ∈ A => False
k ∈ B=> True
Q∈B = >False
Step-by-step explanation:
Given
A is the set of integers greater than - 7 and less than - 3
B={c, h, j, k, v, y}
For set A:
The integers greater than -7 will be -6,-5 ....
As the set has integers less than -3, the set will be:

<u>Cardinalities:</u>
Cardinality is the number of elements in the set.
So,

Now for the statements:
-6 ∈ A True as -6 is a member of set A
-14 ∈ A False as -14 is not a member of A
k ∈ B True
Q∈B False
Hence,
n(A) = 3
n(B) = 6
-6 ∈ A => True
-14 ∈ A => False
k ∈ B=> True
Q∈B = >False
Answer:
opt. B
Step-by-step explanation:
g=60 because equilateral triangle ang=60
<KMN=120 because of linear pair
<h= 180-(120+29)= 31
g+h= 60+31= 91
Answer:
C. 4000
Step-by-step explanation:
let the number of females be : x
number of males be: 10000-x
(10000-x)*105/100 + x*106/100 =10540
10000*105/100 - 105x/100 + 106x/100 =10540
100*105 + x/100 =10540
x/100 =10540-10500
x =40*100
x =4000
Hope this helps!
