Minimum fraction: 0
Question summary: Let us consider the sets [Error converting from MathML to accessible text.] Choose the true statement (there may be more than one) : The origin belongs to both [Error converting from MathML to accessible text.]; For every [z equals z subscript 0] the set X can be identified with a subset of [real numbers squared]; [Y with ring operator on top subset of partial differential X]; The complement set of Y is compact; The sections of Y by planes [z equals z subscript 0] are ellipses; [X with ring operator on top subset of Y to the power of c subset of Y apostrophe subset of X with bar on top subset of X apostrophe]
Right answer summary: The origin belongs to both [Error converting from MathML to accessible text.]; For every [z equals z subscript 0] the set X can be identified with a subset of [real numbers squared]; [Y with ring operator on top subset of partial differential X]
