Find the product and express it in scientific notation. 3.1 x 10-4 x 8.5 x 10-2

Step-by-step explanation:

The given expression :

To solve it , we first combine decimal numbers together, we get

 [∵In scientific notation the decimal number has only one number at the left-side of the decimal.]

Hence, the answer is . [In scientific notation.]

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 %

the answer would be c
