No. 1: A water system of 2 inches (inside diameter) pipe, having a length of 1/4mile, is to be flushed with a volume of water equal to twice that contained in the system. How much water
(number of gallons) must be flushed through the system. (1f13 = 7.481 gallons)

slope is 35 and 20 miles is the y-intercept.

step-by-step explanation:

answer: 7

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 %
