I know it’s a bit blurry, but option A. If 60 students read four books, then 15 students read 5 or more books.

B. More than half of the students read fewer than 3 books.

C. If 60 students read four books, then 120 students read two or more books.

D. Twenty-two percent of the students read four or more books.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
