The New York City Department of Education (NYCDOE) reported that in 2013 from 15,280 seniors in the Borough of Manhattan only 3,401 graduated with advanced Regents diplomas. Concerned educators wanted to implement strategies to improve the number of students receiving advanced diplomas. They selected 180 seniors at random who received advanced Regents diplomas to evaluate their study programs. Identify the population of interest to the concerned educators.

What is the greatest number of parts of a circle that can be formed by cutting the circle with 7 straight cuts? (note: the parts do not have to be equal in size)

If abcde is reflected over the x-axis and then translated 3 units left, what are the new coordinates d?

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 > ?
