Answer:

$V=4x^3-30x^2+54x$

Step-by-step explanation:

From the question we are told that

Breath of cardboard h=6

Length of cardboard l=9

Let x be the height when fold

Generally the new rectangle is mathematically given as

Breath $h'=(6-2x)$

Length $l'=(9-2x)$

Generally the Volume of tray is mathematically given as

$V=L*B*H$

$V=(9-2x)*6-2x*x$

$V=x(4x^2-30x+54)$

$V=4x^3-30x^2+54x$

Suppose that a class contains 15 boys and 30 girls, and that 10 students are to be selected at random for a special assignment.

natka813 [3]

Prob of selected students times prob of selecting boys times prob of selecting 3 boys
total students = 15b + 30g = 45 students

1. 10s/45t = 0.22
2. 15b/45t = 0.33
3. 3b/15b = 0.2

0.22×0.33×0.2=0.0148

1.48%

I'm not sure 100%... double check answer please
