Explain the place value relationship when the same two digits are next to each other in a multi-digit number

An eight-sided die, which may or may not be a fair die, has four colors on it; you have been tossing the die for an hour and have recorded the color rolled for each toss. what is the probability you will roll a brown on your next toss of the die? express your answer as a simplified fraction or a decimal rounded to four decimal places.

If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).

Graph the equationy= x+3[tex]y = x + 3[/tex]
