ˉx = 28.55, ˜x = 28, mode = 28. ˉx = 2.05, ˜x = 2, mode = 1. Mean: nxmin ≤ ∑ x so dividing by n yields xmin ≤ ˉx, so the minimum value is not above average. Median: the middle measurement, or average of the two middle measurements, ˜x, is at least as large as xmin, so the minimum value is not above average.Find A. When divided by x - 1, the polynomial P (x) = x 5 + 2x 3 +Ax + B, where A and B are constants, the remainder is equal to 2. When P (x) is divided by x + 3, the remainder is equal -314. Find A and B.
