What is q²-p² divided by q-p?
q + p
How do you write the negation of if and then?
If p then q is represented as p -> q Negation of "if p then q" is represented as ~(p -> q)
How does every rational number have an additive inverse?
By definition, every rational number x can be expressed as a ratio p/q where p and q are integers and q is not zero. Consider -p/q. Then by the properties of integers, -p is an integer and is the additive inverse of p. Therefore p + (-p) = 0Then p/q + (-p/q) = [p + (-p)] /q = 0/q.Also, -p/q is a ratio of two integers, with q non-zero and so -p/q is also a rational number. That is, -p/q is the additive inverse of x, expressed as a ratio.
Where p and q are statements p and q is called what of p and q?
The truth values.

In pea plants purple flowers are dominant to white flowers what is the punnet square?
For the cross between two pea plants with purple flowers that are both heterozygous (Pp), the Punnett square would show the genotypes: PP, Pp, Pp, and pp, and the phenotypic ratio of 3 purple flowers to 1 white flower.
If p q and q r then p r. Converse statement B.A syllogism C.Contrapositive statement D.Inverse statement?
Converse: If p r then p q and q rContrapositive: If not p r then not (p q and q r) = If not p r then not p q or not q r Inverse: If not p q and q r then not p r = If not p q or not q r then not p r
What are the results of a cross between parents with genotypes Pp and pp?
The results would be a 50% chance of offspring with genotype Pp and a 50% chance of offspring with genotype pp. This is because the parent with genotype Pp can pass on either a P or a p allele, while the parent with genotype pp can only pass on a p allele.
What is the sum or difference of p and q?
The sum of p and q means (p+q). The difference of p and q means (p-q).
What is the truth table for p arrow q?
Not sure I can do a table here but: P True, Q True then P -> Q True P True, Q False then P -> Q False P False, Q True then P -> Q True P False, Q False then P -> Q True It is the same as not(P) OR Q
What is q²-p² divided by q-p?
q + p
If p is 50 of q then what percent of p is q?
If p = 50 of q then q is 2% of p.
What are some eight letter words with 1st letter Q and 4th letter P and 5th letter P?
According to SOWPODS (the combination of Scrabble dictionaries used around the world) there are 5 words with the pattern Q--PP---. That is, eight letter words with 1st letter Q and 4th letter P and 5th letter P. In alphabetical order, they are: quippers quippier quipping quippish quopping
How do you write the negation of if and then?
If p then q is represented as p -> q Negation of "if p then q" is represented as ~(p -> q)
What does p over q mean in algebra?
P! / q!(p-q)!
Do you use pp or pg for pages?
Use p for a single page. For example: (p 7) Use pp for multiple pages. For example: (pp 300-301)
Why does multiplication or division with a negative number yield a negative answer?
The assertion in the question is not always true. Multiplying (or dividing) 0 by a negative number does not yields 0, not a negative answer.Leaving that blunder aside, let p and q be positive numbers so that p*q is a positive number.Thenp*q + p*(-q) = p*[q + (-q)] = p*[q - q] = p*0 = 0that is p*q + p*(-q) = 0Thus p*(-q) is the additive opposite of p*q, and so, since p*q is positive, p*(-q) must be negative.A similar argument works for division.
