ANSWER



EXPLANATION.
The given binomial is

One property about all the terms in this binomial expansion is that:
The degree of each term is 10.

degree=4+6=10

degree=3+7=10

degree=6+4=10

degree=5+0=5
All the terms with degree 10 are the correct options
can be factored into
. To double-check, you can multiply the terms together again using FOIL: first, outside, inside, last.
(3x)(x) + (3x)(8) + (-1)(x) + (-1)(8)
3x² + 24x - x - 8
3x² + 23x - 8
Check.
In finding this value you average lower and upper bound
(0.6+0.82)/2 = 0.71
=0.71 estimated
margin of error = distance from estimate point lower/ upper bound
This interval will be twice margin error
(0.82-0.6)/2 = 0.11
How far is 0.82 from 0.71 ??
=0.11=11%
