Creating an equation gives n - 5 as our answer.
The answer is 1/4
2 divided by 2 is 1
and 8 divided by 2 is 4
Answer:
What are the answers to your question?
Step-by-step explanation:
Out of the 52 cards in a deck, there are 13 clubs and 4 aces. The given situation is an inclusive event because out of the 4 aces there is one of them that is a club. The probability therefore,
P(ace) + P(club) - P(inclusive event)
Substituting gives,
4/52 + 13/52 - 1/52 = 4/13
The answer is letter C. 4/13.
Given:
4 relations in the options.
To find:
The relation which represents a function.
Solution:
We know that, a relation is a function if there exist a unique output value for each input value.
In option A, we have two output values y=-5 and y=1 for single input value x=-1. So, it is not a function.
In option B, we have two output values y=2 and y=4 for single input value x=3. So, it is not a function.
In option C, we have two output values y=1 and y=7 for single input value x=-1. So, it is not a function.
In option D, we have unique output value for each input value. So, it is a function.
Therefore, the correct option is D.
