Iwill give brainliest to the correct answer. sam rotated parallelogram abcd 90° clockwise around the origin. if angle a is 130° and angle b is 50°, what is the degree measurement of angle a'? a. 80° b. 130° c. 50° d. 180°

Describe the symmetry of the figure. identify lines of symmetry, if any. find the angle and the order of any rotational symmetry.

One line passes through (-7,-4) and (5,4) . another line passes through the point (-4,6) and (6,-9)

which of the following sets of data would produce the largest value for an independent-measures t statistic? the two sample means are 10 and 20 with variances of 20 and 25 the two sample means are 10 and 20 with variances of 120 and 125 the two sample means are 10 and 12 with sample variances of 20 and 25 the two sample means are 10 and 12 with variances of 120 and 125
