Astudent entering a doctoral program in educational psychology is required to select two courses from the list of courses provided as part of his or her program.
(a) list all possible two-course selections.
(b) comment on the likelihood that
epr 602 and epr 684
epr 602 and epr 684 will be selected.
epr 622 educational research planning and interpretation
epr 664 nonparametric statistic
epr 602 interpretive methods in educational research

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

the two may have that, even a breakdown is probably offered

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
