Comprehension:Read the following information and answer the questions ...
Formula used:
n(A U B) = n(A) + n(B) - n(A ∩ B)
Calculation:
n(A) = 28
n(B) = 32
n(A U B) = 40
n(A ∩ B) = 32 + 28 - 40 = 20

Similar ACT Doubts

Adapted from “The Fear of the Past” in What’s Wrong with the World by G.K. Chesterton (1910)The last few decades have marked by a special cultivation of the romance of the future. We seem to have made up our minds to misunderstand what has happened; and we turn, with a sort of relief, to stating what will happen—which is (apparently) more easy. The modern man no longer presents the memoirs of his great grandfather; but is engaged in writing a detailed and authoritative biography of his great-grandson. Instead of trembling before the specters of the dead, we shudder abject under the shadow of the babe unborn. This spirit is apparent everywhere, even to the creation of a form of futurist romance. Sir Walter Scott stands at the dawn of the nineteenth century for the novel of the past; Mr. H. G. Wells stands at the beginning of the twentieth century for the novel of the future. The old story, we know, was supposed to begin: "Late on a winters evening two horsemen might have been seen . . ." The new story has to begin: "Late on a winters evening two aviators will be seen . . ." The movement is not without its elements of charm; theres something spirited, if eccentric, in the sight of so many people fighting over again the fights that have not yet happened; of people still aglow with the memory of tomorrow morning. A man in advance of the age is a familiar phrase enough. An age in advance of the age is really rather odd.Which of the following is the best form of the underlined selection, "The movement is not without its elements of charm"?

Directions:Read the passages and choose the best answer to each question.PassageThe molar heat of fusion is the amount of heat necessary to melt (or freez e) 1.00 mole of a substance at its melting point at a constant pressure. The molar heat of fusion for water is 6.02 kilojoules per mole (kJ/mol).The equation for molar heat of fusion is:q = ΔHfus(mass/molar mass)In this equation, q is the total amount of heat involved, ΔHfus represents the molar heat of fusion (this value is a constant for a given substance), and (mass/molar mass) represents the number of moles of a given substance.The following table lists molar heats of fusion, boiling points, and melting points for several elements.Q.The boiling point of potassium is 759.90 C. If potassium follows the general pattern of the other elements in the table, its heat of fusion would be
