Acircle is inscribed in an equilateral triangle. a point in the figure is selected at random. find the probability that the point will be in the part that is not shaded.

a. about 25%
b. about 40%
c. about 60%
d. about 50%

see explanation

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

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
