Pls Help asap Directions: Find the range and IQR for the following data sets.
1. {6, 12, 8, 15, 9, 7} 2. {2, 12, 52, 33, 8, 14}

Q1

Q3

IQR (Q3-Q1)=

3. {3, 9, 11, 8, 6, 12, 5, 4}

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.
