A statistics student had excluded three outlier values when constructing a histogram of a frequency distribution. His teacher directed him to remake the histogram and include the outliers. Which of the following must be true? The class boundaries would change.

The shape of the histogram changes.

The shape of the histogram remains the same.

The interpretation of the histogram remains the same.

529 and 531

step-by-step explanation:

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.
