An animal researcher randomly selected 98 dogs and cats and recorded if they napped between 2:00 p. m. and 2:30 p. m. The two-way table displays the data. Suppose an animal is randomly se cat and let event N = nap. What is 0 38 Napping Habit Nap No Nap Total o Dog 15 32 47 Animal Type Cat 23 28 51 Total 38 60 98 0 23 ​

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.

the answer is su.k.my? ? co.kc
