0.4 ,2/5 as a fraction, and a ratio 2:5 !
Though you did not post the scatter plot, I was able to figure out the scatter plot.
From the scatter plot, the labelled points are (32, 23) and (43, 30).
The equation of a line passiong through the points (32, 23) and (43, 30) is given by:

Therefore, the equation that represents the linear model is
Answer:
26 students are good in mathematics only.
28 students are not good in any of the three courses.
30 min = 30/60 hr = 0.5 hr
d = rt
100 = r*0.5
100/0.5 = r
200 = r
r = 200 mph.
We know that Rate = distance/time
(30 minutes is .5 hour)
Rate=100 mile/.5 hour
Divide and we get:
Rate=200 MPH
(Hint: MPH is Miles per Hour---Per means "for each")
Make sense?
