What is the theoretical probability of rolling a sum of 8 on one roll of two standard dumber cubes?

Agiven line has the equation 2x + 12y = −1. what is the equation, in slope-intercept form, of the line that is perpendicular to the given line and passes through the point (0, 9)? y = ( )x + 9

Which shows the image of rectangle abcd after the rotation (x, y) → (–y, x)?

Create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1.
