ABCD is a quadrilateral inscribed in a circle, as shown below: Circle O is shown with a quadrilateral ABCD inscribed inside it. Angle A is labeled x plus 16. Angle B is labeled x degrees. An

What equation can be used to solve for angle A? (5 points)

(x + 16) + (6x − 4) = 180
(x + 16) + (x) = 90
(x + 16) − (x) = 90
(x + 16) − (2x + 16) = 180

Given a(-12,5) and b(12,29) find the point that divides the line segment ab three-eighths of the way from a to b

Evaluate the expression for the given value of the variable 7a - 4a for a =8

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
