Consider adding to the incidence axioms another that says "axiom4: every line contains exactly three distinct points." we know that fano's geometry (p. 18) satisfies this set of axioms. explain carefully using only the 4 axioms why there must be at least 7 points and at least 7 lines in order for a geometry to satisfy these 4 axioms.

Which of the following system of equation is not equal to the system of equations is not equal to the system of equations shown below

Write two subtraction equations that are equivalent to 5 + 12 = 17.

Christine wong has asked dave and mike to her move into a new apartment on sunday morning. she has asked them both, in case one of them does not show up. from past experience, christine knows that there is a 40% chance that dave will not show up and a 30% chance that mik a. what is the probability that both dave and mike will show up? (round your answer to 2 decimal places.) b. what is the probability that at least one of them will show up? c. what is the probability that neither dave nor mike will show up? (round your answer to 2 decimal places.)e will not show up. dave and mike do not know each other and their decisions can be assumed to be independent.
