First divide 6/(6+6+8) =0.3
Then multiple it by 100 to get the probability percentage 30%
The wording of this question is a bit confusing... You can't write a sequence in sigma notation, but rather a series or sum. I think the question is asking you to write the sum of the sequence,

which would be

in sigma notation.
To do this, notice that the denominator in each term is a power of 2, starting with
and ending with
. So in sigma notation, this series is

Answer:
0.79
Step-by-step explanation:
add up the probability that is less than or equal to 0, which is 0.17+0.13+0.33+0.16 = 0.79
Answer:
Step-by-step explanation:
I assume you mean to write a polynomial function. I don't know how righting works.
The simplest one I can think of is
y = 3x⁷
