10. In list T, consists of 30 positive decimals. None of which are integers. The sum of the 30 decimals is S. The estimated sum of the 30 decimals is E. The estimated sum is calculated as follows: Each decimal in T whose tenth digit is even is rounded up to nearest integer, and each decimal in T whose tenth digit is odd is rounded down to nearest integer. E is sum. If 1/3 of decimals in T have even tenth digit that is even, what is a possible value of E-S? I. -16 II. 6 III. 10 A. I only B. I and II only C. I and III only D. II and III only E. I, II, and III

I've been working on this for a few days and i just don't understand, it's due in a few hours. you.the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case.part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
