<span>(230 + w) x ( t ) = ( 275 )
(230 - w) x ( t ) = ( 185)
t = 275 / (230 + w)
t = 185 / (230 - w)
275 / (230 + w) = 185 / (230 - w)
275(230 - w) = 185(230 + w)
63250 - 275w = 42550 + 185w
20700 = 460w
w = 45mph

The median of the distribution is 4.
<h3>What is the median?</h3>
A histogram is used to represent data graphically. The histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval.
The median is the number at the center of the data set.
Arranging the numbers in the histogram in ascending order is: 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 6, 6, 7, 8, 9, 10
- Total numbers = 21
- Median = 1/2 x (n + 1)
1/2 x 22 = 11th number 4

Answer:
11
Step-by-step explanation:
Let the number be x.
Then by the question,
2x+4 = 3x-7
x=11
Well, what you need to figure out is what times 9 is 63. That would be 7. So n=7 :)
