Total number of ways will be 
Step-by-step explanation:
We have to select 7 countries
3 countries selected from a block of 54
So number of ways of selecting these three countries 
Now 1 country is selected from 66 block
So number of ways to select 1 country = 
Now next 3 country is selected from 69 country
So 
So total number of ways to select 7 countries = 24804×65×52394 
X=2
-x^2=-2^2=4
-(x)^2=-(2)^2=-4
3(X+5)=3X+15
3 x X+5=3X=5
Answer:
C
Step-by-step explanation:
In a proportional relationship the constant of proportionality k is
k = 
Check this ratio for each of the values
A
= 1.5 ,
= 1.5 ,
= 1.4347.... ← Thus not A
B
= 1.1875 ← Thus not B
C
= 1.5 ,
= 1.5 ,
= 1.5
Thus the table with k = 1.5 is Table C
