human center because we describe stuff by what we see and obserevs
Let me re-write the proposition:
p↔q⊕(¬p↔¬r)∧¬q.
Generally, the number of rows in a truth table depends on the number of Variables. Here we have 3 Variables: p,q and r. Each of them can have either the value of 1 or 0, which gives us 2*2*2 possibilities, or 2³, that is 8 possibilities and 8 rows:
p=0, q=0, r=0
p=0, q=0, r=1
p=0, q=1, r=0
p=0, q=1, r=1
p=1, q=0, r=0
p=1, q=0, r=1
p=1, q=1, r=0
p=1, q=1, r=1
Answer:
Optimistic duration
Explanation:
The following three concepts are Project management concepts:
Optismitic duration: Estimation of the shortest duration of a task, taking into account the difficulty, etc.
Pessimistic duration: Estamation of the longest duration of a task, taking into account the difficulty, etc
Expected duration: Expected duration of a task, kind of a compromise between the optmistic duration and the pessimistic duration.
Which of the following is the estimate of the minimum amount of time it would take to perform a task?
The answer is Optimistic duration
Answer:
public static String repeat(String text, int repeatCount) {
if(repeatCount < 0) {
throw new IllegalArgumentException("repeat count should be either 0 or a positive value");
}
if(repeatCount == 0) {
return "";
} else {
return text + repeat(text, repeatCount-1);
}
}
Explanation:
Here repeatCount is an int value.
at first we will check if repeatCount is non negative number and if it is code will throw exception.
If the value is 0 then we will return ""
If the value is >0 then recursive function is called again untill the repeatCount value is 0.
