Abox with a square base and open top must have a volume of 32,000 cm3. find the dimensions of the box that minimize the amount of material used.(a) sides of base (cm)(b) height (cm)

Step-by-step explanation:

Given

Volume of box

Let b be the square base and h be the height of box

Volume

Surface Area

Differentiate A w.r.t b to get maxima/minima

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 %

2x+60=
