What is the explicit formula for the geometric sequence with this recursive formula? a1 = -6

an = an-1•(¼)

○A. an = ⅙•(-4)(n-1)

○B. an = -4•(⅙)(n-1)

○C. an = -6•(¼)(n-1)

○D. an = ¼•(-6)(n-1)

C

Step-by-step explanation:

I think

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
