We have been given that
Luke can read 4 3/4 pages in 15 minutes.
Hence in 1 minute Luke can read 19/60 pages.
Sarah can read 1 1/2 pages in 4 minutes.
Hence, in 1 minute Sarah can read 3/8 pages.
Now, let us find how many pages they can read in 2 hours = 120 minutes.
In 2 hours Luke can read pages.
In 2 hours Sarah can read pages.
The difference in the number of pages is 45 - 38 = 7 pages.
Therefore, Sarah can read 7 more pages than Luke in 2 hours.
Answer:
The correct answer is B) the mean will decrease and the median will stay the same.
Step-by-step explanation:
This is true because the mean is the average, which is all of the values added together and then divided by the number of teachers. Reducing anyone's salary will reduce the mean.
The median stays the same since she was already the lowest (or tied for the lowest) paid in the group. Therefore, the middle term (the median) is unchanged.
The answer is 0.87. Hope i could help
