O 3x2 - 4x - 1 = (3x + 1)(x - 1)
O 3x2 - 2x - 1 = (3x - 1)(x + 1)
o 3x2 - 4x + 1 = (3x - 1)(x - 1)
O 3x2 - 2x + 1 = (3x - 1)(x - 1)

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

the one below it is a function

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
