For this case, the first thing you should know is:
d: v * t
Where,
d: distance
v: speed
t: time
To go to school by bus we have:
d = 45 * t
To return from school we have:
d = 2.5 * (1-t)
how the distance is the same:45 * t = 2.5 * (1-t)
Answer:
the equation that will help find the time it takes chelsea to get to school on the bus is:
45 * t = 2.5 * (1-t)
Note: the equation will have one solution.
Answer: The correct answer would be 0.58.
The value of r of a set of data tells us how close the values are to the line of regression of the data. If you add in an outlier, it would make the overall r value of the points further from the line. In other words, it would go further from 1.
In this case, our initial r value was positive, so it makes sense to keep it positive. 0.58 would be the best choice.
