F(x) = (128/127)(1/2)x, x = 1,2,. determine the requested values: round your answers to three decimal places (e. g. 98.765). (a)p(x ≤ 1) (b)p(x > 1) (c) mean (d) variance

yes

step-by-step explanation:

give me the question

\

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.
