One brand of cookies is sold in three different box sizes: The small box had half the volume of the medium box. The large has twice the volume of the medium box . The volume of the medium box is x. If someone bus ones of each size which expression shows the combined volume of three boxes ?

Step-by-step explanation:

There are three different box sizes: The small, the medium, and the large size.

The small box has half the volume of the medium box. If x is the volume of the medium box, then:

The volume of small box =

The large's volume is twice the medium's volume, thus:

The volume of large box=2x

The total volume of the three boxes is:

Operating:

The expression for the combined volume of the three boxes is

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 %
