A student entering a doctoral program in educational psychology is required to select three courses from the list of courses provided as part of his or her program. (a) List all possible three-course selections. (b) Comment on the likelihood that EPR 659, EPR 683, and EPR 628 will be selected. Click the icon to view the course list. A. 659, 628, 687 B. 683, 684, 687 C. 659, 659, 683 E. 683, 628, 687 G. 683, 684, 628 I. 659, 659 K. 659, 684, 687 M. 687, 604, 687 D. 659, 684, 628 F. 684, 628, 687 H. 684, 687, 684 J. 659, 683, 684 L. 659, 683, 628 N. 659, 683, 687 ​

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

its a, i had the same answer, its from study island right
