Number of functions from X to X are:
Ques 2)
Number of relation from X to X are:
<h2>
Step-by-step explanation:</h2>
Relation--
A relation from a set A to set B is the set of all the ordered of the type:
(a,b) where a belongs to A and b belongs to B.
if A has m elements and B has n elements.
Then the total number of relation from A to B are:
Function--
A function from a set A to set B is the set of all the ordered pair where each element of set A is mapped to a single element of the other set.
i.e. every element has a single image.
if A has m elements and B has n elements.
Then the total number of functions from A to B are:
5) slope is y=mx+b
3) cross the y-axis
1) perpedicular to the y-axis
4) parallel
sorry it's in a random order and idk #2
Answer:
Step-by-step explanation:
Given that in the American justice system, a criminal is presumed innocent until proven guilty, meaning that the prosecution must gather enough evidence to prove that the defendant has actually committed a crime.
H0: The defendent is not guilty
Ha: The defendent is guilty
(Two tailed test)
a) given above
b) Type I error here is false rejection of H0, i.e. charging defendent guilty even though actually he is not guilty
c) Type II error here is accepting that the defendent is not guilty even though he is guilty
d) Whenever type I increases type II error decreases and vice versa.
But as per ethics, an innocent person should not be punished at any cost, so care should be taken to avoid type I error which is more serious than avoiding type II error.
