QUICK Which question is best modeled with a division expression? A: How much does it cost to buy 3 and one-half pounds of apples at $2 per pound?
B: How many apples are needed for 2 pies if the recipe uses 3 and one-half apples per pie?
C: How many more apples are needed if a recipe uses 3 and one-half apples and you only have 2 apples?
D: How many apples are in each pie if a total of 3 and one-half apples were used to bake 2 pies?

D

Step-by-step explanation:

Which is about .57

Let's see if we can recreate the histogram from the description.

Time count

0.5  0

1       0

1.5    2

2      1

2.5   3

3       1

3.5    2

4       1

4.5    0

5       0

The mean is between 2.5 and 3 so that will definitely decrease with a data point that's less that that, as 0.5 is.  

For 10 data points the median is the average of the 5th and 6th when sorted, and those are both 2.5.  When the new point is added the median will be the 6th of 11 points, still 2.5 in this story.

B  the mean will decrease
