Solve the problem. a class has 9 students who are to be assigned seating at random. what is the probability that the students will be arranged in order from shortest to tallest? (assume that no two students are the same height.) 0.00000276 0.1000 0.0000248 0.00002756

there are 9 possible arrangements so it would be 1:9 converted to a decimal. i would guess its option A

I'm not confident

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
