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:
33
Step-by-step explanation:
You find the area of each triangle and that is (4*3)/2 which is equal to 6 but because all four sides are the same size you would multiply 6 by 4 so 6*4=24 you must also find the area of the bottom and that would be 3*3= 9 then you'd add them together 24+9=33 i hope that this helps!
-3 because 3-3=0! So that is your answer! Hope this helps
Part 1) The equation of a circle is (x+4)²+(y−5)²<span>=121.
What is the center and radius of the circle?
we know that
the equation of a circle is of the form
(x-h)</span>²+(y-k)²=r²
in the problem
(x+4)²+(y−5)²=121.------> (x+4)²+(y−5)²=11²
the center (h,k) is the point (-4,5) and the radius is 11
Part 2) we have that
(x+15)²+(y−12)²=25-------> (x+15)²+(y−12)²=5²
we know that
<span>the greatest distance, in feet, a person could be from the lamp and be detected is the radius
</span>
the radius is equal to 5 ft
the answer Part 2) is 5 ft
Part 3) we have that
(x−9)²+(y+11)²=16--------> (x−9)²+(y+11)²=4²
the radius is equal to 4 m
so the diameter is ------> 4*2-----> 8 m
the answer Part 3) is
8 m
If we know price of 10 pounds sack and we want to know price of 1 pound we have to just divide price of 10 by 10, so:
6.55=10=0.655
Now we can round it
0.655=0.66 because the last digit is 5.
Answer is 0.66
