Atank containing oil is in the shape of a downward-pointing cone with its vertical axis perpendicular to ground level. in this exercise we will assume that the height of the tank is h=10 feet the circular top of the tank has radius r=5 feet, and that the oil inside the tank weighs 57 pounds per cubic foot. how much work (w) does it take to pump oil from the tank to an outlet that is 1 foot above the top of the tank if, prior to pumping, there is only a half-tank of oil? note: "half-tank" means half the volume in the tank. for this problem a pound is to be taken as a unit of weight (not of mass), so it is not necessary to multiply by the gravitational acceleration constant in order to find the work.

can i get the link to the assignment?

step-by-step explanation:

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

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 %
