What is the mean
of 98, 99, 100,
90, 98, 100?

97.5

Step-by-step explanation:

Mean is calculated as total sum of values in a data set ÷ number of values in a data set

Given the data set below, add the values in the data set then divide by number of values in the data set (6)

Mean = 98 + 99 + 100+ 90 +98 +100/6

=585/6

=97.5

answer: i can’t tell you that

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.
