<em>Complete Question:</em>
In a jar there are 19 red jelly beans and 10 green jelly beans. In how many ways can you pick 4 red jelly beans and the same number of green jelly beans?
Answer:
Step-by-step explanation:
Given
Red Jelly Beans = 19
Green = 10
Required
Select 4 out of 19 red jelly beans and 4 out of 10 green jelly beans
The keyword in the question is pick and this implies combination;
4 from 19 red jelly beans is calculated as follows
Where n = 19 and r = 4
Similarly;
4 from 10 green jelly beans is calculated as follows
Ways of selecting both is calculated as follows
Answer:
A - Not Function
B - Function
C - Function
D - Not Function
E - Function
Step-by-step explanation:
For a relation to be a function, each value of input should have exactly one output. Which means that for one value of x, there should only one value of y. If the relation has repetition of x in its ordered pairs, it means that for one value of x, there are two or more values of y, hence the relation is not a function
(Consult the diagram below)
<h3>A - {(6,12),(3,1),(−1,13),(6,4)} </h3>As x = 6 is being repeat, it means that x=6 has two values of y that are 12 and 4. IT IS NOT A FUNCTION.
<h3>B - {(−1,−2),(−4,−4),(0,−5),(7,−5)} </h3>No repetition of x, IT IS A FUNCTION.
<h3 /><h3>C - {(−5,1),(4,10),(5,10),(6,7)} </h3>No repetition of x, IT IS A FUNCTION.
<h3 /><h3>D - {(−1,4),(1,6),(−1,−2),(0,7)} </h3>As x = -1 is being repeat, it means that x=-1 has two values of y that are 4 and -2. IT IS NOT A FUNCTION.
<h3>E - {(−2,8),(2,1),(−4,8),(7,9)}</h3>No repetition of x, IT IS A FUNCTION.
