Using it's concept, the interval that contains the median number of characters is: 30 - 40.
<h3>What does the histogram shows?</h3>
The problem is incomplete, but researching it on a search engine, we have that:
- She had 3 messages between 0 and 10 characters.
- She had 1 message between 10 and 20 characters.
- She had 1 message between 20 and 30 characters.
- She had 2 messages between 30 and 40 characters.
- She had 1 message between 60 and 70 characters.
- She had 1 message between 100 and 120 characters.
<h3>What is the median of a data-set?</h3>
The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.
In this problem, we have a data-set of 9 elements, hence the median is the 5th element, as:
- The first half is composed by the first four elements.
- The second half is composed by the last four elements.
The fifth element of the histogram is in the interval 30-40, which is the interval that contains the median.

Answer:
-6+4=-2
Step-by-step explanation:
That is one solution
i think its twenty hours.....but dont take my word on it im not 100% on it
if the medicine leaves the blood stream at 10% per hour and 6 hours goes by 60% of the medicine would be gone. 60% of 50 is 30. so 30mg would have left. so there is only 20mg left.
Note: Consider the below figure attached with this question.
Given:
The ordered pair(6,y) is on line AC.
To find:
The y of this ordered pair.
Solution:
From the below figure it is clear that endpoints of AC are A(-7,-4) and C(1,4). So, equation of AC is
Subtracting 4 from both sides, we get
Thus, the equation of line AC is .
Put x=6 to find the y for the ordered pair (6,y).
Therefore, the value of y is 9.
