Alternative Fuel Vehicles A survey was conducted by the local chapter of an environmental club regarding the ownership of alternative fuel vehicles (AFVs) among the members of the group. An AFV is a vehicle that runs on fuel other than petroleum fuels (petrol and diesel) or that does not involve solely petroleum fuels. It was found that of the 80 members of the club surveyed, 22 of them own at least one hybrid car, 12 of them own at least one electric car, and 4 of them own at least one hybrid and at least one electric car. If a member of the club selected at random is surveyed, what is the probability that he or she:
a. Owns only hybrid cars?
b. Owns no alternative fuel vehicles?

Select each true statement about the continuity of f(x) at x = 1. Select all that apply: ☐ f(x) is not continuous at x = 1 because it is not defined at x = 1. ☐ f(x) is not continuous at x = 1 because lim f(x) does not exist. x+1 ☐ f(x) is not continuous at x = 1 because lim f(x) ‡ f(1). x+→1 ☐ f(x) is continuous at x = 1.arrow_forward2. Consider the following argument: (a) Seabiscuit is a thoroughbred. Seabiscuit is very fast. Every very fast racehorse can win the race. .. Therefore, some thoroughbred racehorse can win the race. Let us define the following predicates, whose domain is racehorses: T(x) x is a thoroughbred F(x) x is very fast R(x) x can win the race : Write the above argument in logical symbols using these predicates. (b) Prove the argument using the rules of inference. Do not make use of conditional proof. (c) Rewrite the proof using full sentences, avoiding logical symbols. It does not need to mention the names of rules of inference, but a fellow CSE 16 student should be able to understand the logical reasoning.arrow_forward

Prove the following. Use full sentences. Equations in the middle of sentences are fine, but do not use logical symbols. (a) (b) (n+3)2 is odd for every even integer n. It is not the case that whenever n is an integer such that 9 | n² then 9 | n.arrow_forward3. (a) (b) Prove the following logical argument using the rules of inference. Do not make use of conditional proof. Vx(J(x)O(x)) 3x(J(x) A¬S(x)) . ·.³x(O(x) ^ ¬S(x)) Rewrite the proof using full sentences, avoiding logical symbols.
