Can you consider marking my answers as brainliest lol it would mean a lot. Hope this helped.
Answer:
the answer is f(x) = n*(-2)
ratio is the wrong word to use, it is for contolled variation in probability. a sequence is controlled by what is known as a function - f(x) is the symbol for a function
Step-by-step explanation:
the following number of the previous one in the sequence is derived by the function f(x)=n*(-2)
2 x -2 = -4 (positive x negative = negative)
-4 × -2 = 8 (negative x negative = positive)
8 x -2 = -16 (positive x negative = negative)
so in the sequence, the trend of -,+ double will go on
Percent means per one hundred so we can say that:
p/100≈(28)/(28+81+45+63+35) guessing with my old eyes :)
p/100≈28/252
p≈2800/252
p≈11.11%
So rounded to the nearest 5% you'd have:
p≈10%
I think the answer is 0.31!
