In 2012, a search engine's index contained 30 trillion web pages. The size of the index triples every year. Let f(t)be the number of web pages (in trillions) in the index at t years since 2012. a. Find an equation of f.
b. Predict the number of web pages the index will contain in 2017.

a) t'(-3, 6) and v'(0, 3)  

step-by-step explanation:

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 %
