Select the line plot with a median score of 6.

mafiozo [28]

Answer: top left
Reason: all plots have twenty dots. Count from either side. If the tenth and eleventh are both on six than that plot is correct. Top left is the only one like that. (the median of 20 being between 10 and 11)

Two trains leave the station at the same, one heading west and the other east. The westbound train travels at 55 miles per hour.

Mars2501 [29]

The time that taken for the two trains is 1.2 hours.

The computation of the time taken for the two trains is shown below:

Given that

The westbound train travels 55 miles per hour.

And, the eastbound train travels 75 miles per hour.

So, the total speed is

= 55 miles per hour + 75 miles per hour

= 130 miles per hour

The distance is 156 miles

So, the time taken is

$= \frac{distance}{speed}\\\\= \frac{156\ miles}{130\ miles\ per\ hour}\\\\$

= 1.2 hours

Therefore we can conclude that the time that taken for the two trains is 1.2 hours.
