Select the correct answer. Given
D = {xIx is a whole number}
E = {xl x is a perfect square between 49 and 100}
F={xl x is an even number between 10 and 20}
The expression Du F means...
The expression DNF means
The expression Dn E means
The expression E N F means
The expression Dn (EU F) means

Step-by-step explanation:

D = {x | x is a whole number}

D = {0, 1, 2, 3, 4,}

E = {x | x is a perfect square between 49 and 100}

E = {64, 81}

F = {x | x is an even number between 10 and 20}

F = {12, 14, 16, 18}

D∪F = {x | x is whole number}

D∩F = {x | x is an even number between 10 and 20}

D∩E = {x | x is a perfect square between 49 and 100}

E∩F = {null set}

D∩(E∪F) = {12, 14, 16, 18, 64, 81}
