A teacher writes the name of each of her 25 students on a slip of paper and places the papers in a box. To call on a student, she draws a slip of paper form the box. Each paper is equally likely to be drawn, and the papers are replaced in the box after each draw. If there are 9 students in the last row, what is the probability of calling on a student in the last row

36%

Step-by-step explanation:

Total Number of Students = 25

The number of students on the last row = 9

The probability of calling a student in the last row

The probability of calling a student in the last row is 36%.

In order to write the formula for another line which is parallel, we need the slope (m). Parallel lines never in fact touch or intersect at any one point. They are either the same lines, occupying the same points, or different parallel lines, never occupying the same points, but sharing the same slope (m).
If we put out equation in slope-intercept format: y = mx+b, we can obtain our needed m.
12x+3y=24 ->> 3y = -12x+24
3y/3 = (-12x+24)/3 ->> y = -4x+8, therefore our m = -4
Now we can use our info to make the line in point-slope format: y-y1 = m (x-x1)
So, y-7 = -4 (x--2) or y-7 = -4 (x+2)
You can leave it like that or convert it:
y-7 = -4x -8 ->> y = -4x -8+7 ->> y = -4x-1
or even in this format: 4x+y=-1
