the table shows the number of minutes per day students spend outside of school reading and doing their math homework. What is the difference of the means as a multiple of the approximate mean absolute deviation​

Using the completing-the-square method, find the vertex of the function f(x) = 2x2 − 8x + 6 and indicate whether it is a minimum or a maximum and at what point. maximum at (2, –2) minimum at (2, –2) maximum at (2, 6) minimum at (2, 6)

The mean of a set of data is -3.82 and its standard deviation is 2.31. find the z score for a value of 3.99.

Look at the following graph of the given equation. determine whether the equation is a function. explain why or why not.
