p-q
q + p
If p then q is represented as p -> q Negation of "if p then q" is represented as ~(p -> q)
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.
The truth values.
p --> q and q --> p are not equivalent p --> q and q --> (not)p are equivalent The truth table shows this. pq p --> q q -->(not)p f f t t f t t t t f f f t t t t
It depends. If the cross is homozygous, then the punnett square will be PPXpp P P p Pp pp p Pp pp Heterozygous PpXPp P p P PP Pp p PP pp If you know how to do the geno and the phenotypes then you're all set
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.
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
The sum of p and q means (p+q). The difference of p and q means (p-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
q + p
If p = 50 of q then q is 2% of 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
If p then q is represented as p -> q Negation of "if p then q" is represented as ~(p -> q)
The expression ( p \land q ) is called the conjunction of ( p ) and ( q ). It represents the logical operation where the result is true only if both ( p ) and ( q ) are true. If either ( p ) or ( q ) is false, the conjunction ( p \land q ) is false.
P! / q!(p-q)!
Use p for a single page. For example: (p 7) Use pp for multiple pages. For example: (pp 300-301)
