Question

**1. What is the contradiction and its truth-value of the
true claim “All trapeze artists are daring people?”**

**2. Given “All scholars are philosophers” is false, what
is the contrary and its truth-value?**

**3. What is the converse of “Some women are body
builders”?**

Answer #1

1. "All trapeze artists are daring people". So the statement is true if the artist is a trapezee artist. That is "if the artists are trapezee artists, then they are daring".Contradiction is "Some artists who are not trapezee artists are not daring people".

2. "All scholars are philosphers is false". So, the truth statement is "Not all scholars are philosophers". Contradiction statement is "All scholars are not philosophers".

3. Converse of "Some women are body builders" is "All women are not body builders".

3. Multiple-Line Truth Functions
Compound statements in propositional logic are truth functional,
which means that their truth values are determined by the truth
values of their statement components. Because of this truth
functionality, it is possible to compute the truth value of a
compound proposition from a set of initial truth values for the
simple statement components that make up the compound statement,
combined with the truth table definitions of the five propositional
operators.
To compute the truth value...

Given the following prediction Sample ID Predicted Value Ground
Truth 1 0.9 1 2 0.3 1 3 0.7 1 4 0.8 -1 5 0.4 -1 6 0.2 -1 (a) (18
Pts) Using 0.5 as the cutoff value, namely, the sample is predicted
as 1 if predicted value >=0.5, otherwise -1. Please compute true
positive rate (tpr, also called recall/sensitivity), false positive
rate (fpr), true negative rate (tnr), false negative rate (fnr),

Claim: If (sn) is any sequence of real numbers with
??+1 = ??2 + 3?? for
all n in N, then ?? ≥ 0 for all n in N.
Proof: Suppose (sn) is any sequence of real numbers
with ??+1 = ??2 + 3??
for all n in N. Let P(n) be the inequality statements ??
≥ 0.
Let k be in N and suppose P(k) is true: Suppose ?? ≥
0.
Note that ??+1 = ??2 +
3?? =...
