Answer:
C
Step-by-step explanation:
This is a combination question.
In the first instance, we select 5 from 20 and in the second case , we select 4 from 20.
The total number of ways to solve the first instance is 20C5 = 15504 ways
The total number of ways to solve the second instance is 20C4 = 4,845
The ratio of the first to the second scenario is 15,504/4,845 = 3.2 = 16 to 5
Answer:
(-1,-9) and (-3,-11) are two pairs whose difference is 8. (-1,-9) and (-3,-11) are two pairs whose difference is 8.
step by step explanation:
subtract and subtract makes addition [- , - = (+) ]
and
addition and subtract makes subtraction = [ + ,- = ( - ) ]
so,
(-1 ) - (-9) = (-1)+ 9
= 8
same with second one
