The multiple regression formula with two predictor variables is ŷ = a + (b1/x1) + (b2/x2). ŷ = a1 + a2 + (b1/x1) + (b2/x2). ŷ = a + (b1)(x1) + (b2)(x2). ŷ = a1 + a2 + (b1)(x1) + (b2)(x2).

The graph shows the distance y, in inches, a pendulum moves to the right (positive displacement) and to the left (negative displacement), for a given number of seconds x. how many seconds are required for the pendulum to move from its resting position and return? enter your answer in the box.

Two language majors, anna and megan, took exams in two languages. anna scored 85 on both exams. megan scored 74 on the first exam and 85 on the second exam. overall, student scores on the first exam had a mean of 82 and a standard deviation of 4, and the second exam scores had a mean of 71 and a standard deviation of 13. a) to qualify for language honors, a major must maintain at least an 85 average across all language courses taken. so far, which of anna and megan qualify? b) which student's overall performance was better?
