Answer:
The statement 
is neither a tautology nor a contradiction.
Step-by-step explanation:
A tautology is a statement that is always true.
A contradiction is a statement that is always false.
We are going to use a truth table to determine whether the statement is a tautology, contradiction, or neither
A truth table shows how the truth or falsity of a compound statement depends on the truth or falsity of the simple statements from which it's constructed.
The statement is compound by these simple statements:
and we are going to use these simple statements to build the truth table.
The last column contains true and false values. Therefore, the statement is neither a tautology nor a contradiction.
Answer:
The value of PC is 40.
Step-by-step explanation:
Consider the complete question is " C is the circumcenter of triangle PQR. PC=3X-7 RC=5X-15 & QC= 51-X What does PC equal?"
All vertices or a triangle are equidistant from its circumcenter.
The value of x is 11.
We need to find the value of PC.
Substitute x=11 in the above equation.
Therefore, the value of PC is 40.
Answer:
The probability of flipping heads is 1/2 and the probability of picking a vowel is 4/10 or 2/5
This thing doesn’t make sense you need to fix for someone can Asher it
Step-by-step explanation:
their sum is
x - 1 + x + x + 1 = 3x
their product is
(x - 1)x(x + 1) = x(x² - 1)
96 × 3x = x(x² - 1)
96 × 3 = x² - 1
288 = x² - 1
x² = 289
x = 17
so, the solution is 16, 17, 18
