Tan finished 3/5 of 45 math problems. each math problem took him 1 4/5 of a minute to complete. at this pace, how much more time, to the nearest minute, will the rest of the problems take him to finish

To solve this problem you must apply the proccedure shown below:

1. Calculate the number of problems finished by Tan, as following:

2. Calculate the number of problems that he has not finished:

3. If each problem finished took him , you have that the rest of problem will take him:

The answer is:

dont know

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 %
