I'll give you brainlest if you can solve this one! I need STEP, please read the question.

What is the logarithmic function modeled by the following table? x f(x) 9 2 27 3 81 4

Solve the system of equations. y= 2x y= x^2 - 15

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
