Answer:
The equation of the line in the slope-intercept form will be:
- y = -7x
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
- m is the slope
- b is the y-intercept
From the attached graph, taking two points
- (0, 0)
- (-10, 70)
Finding the slope between (0, 0) and (-10, 70)
Determining the y-intercept:
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear that:
at x = 0, y = 0
Thus, the y-intercept b = 0
Now, substituting m = -7 and b = 0 in the slope-intercept form
y = mx+b
y = -7x + 0
y = -7x
Therefore, the the equation of the line in slope-intercept form will be:
- y = -7x
Answer:
0.1997 or 19.97%
Step-by-step explanation:
Have taken course online (H) = 23%
Have NOT taken course online (N) = 77%
Have taken course online and don't believe they provide same value (H&D) = 61%
Have NOT taken course online and don't believe they provide same value (N&D) = 73%
The probability that a student has taken a course online given that she does not believe that online courses provide the same educational value as one taken in person is;
There is a 0.1997 or 19.97% chance that she has taken an online course before.
