Part A: Calculate and interpret the mean of X. Part B: The standard deviation is 0.879, interpret the standard deviation.

Create and solve a linear equation that represents the model, where squares and triangles are shown evenly balanced on a balance beam. assume the weight of a square is 1 unit and the weight of a triangle is unknown.

Select 2 statements that are true about the equation y+6=-10(x-3).1) the slope of the line is -102) the slope of the line is 33) one point on the line is (3,6)4) one point on the line is (3,-6)

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827
