You are using the table of random digits to choose a simple random sample of 6 students from a class of 30 students. you label the students 01 to 30 in alphabetical order. line 133 of table b is given below.
line 133: 45740 41807 65561 33302 07051 93623 18132 09547
using this line of random digits, your sample contains the students labeled
04, 18, 07, 13, 02, 05
04, 18, 07, 13, 02, 07
30, 20, 31, 32, 09, 07
45, 74, 04, 18, 07, 65

its a

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.
