What is the mass of a liquid having a density of 1.40g/ml and volume of 30ml

42mL

Step-by-step explanation:

Density equals Mass divided by Volume. In that way, you are missing the Mass, so it would be Density multiplied by Volume.

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 %
