A quality control inspector randomly selected 40 phones to be tested at the Y-Phone Factory. The researcher dropped each phone from a height of a table onto a concrete surface and found only 15 of the phones had the glass surface break Based on this test what is the probability that the glass won't break on the next test?
0.375
O 0.415
0.395
O 0.355

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 discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

from the sentence, "tomorrow morning, akiko will arrive an hour late" depicts a third person perspective because it doesn't use any pronoun to replace akiko, the subject of the sentence, and it is in singular form since akiko is only one person.
