Answer:
2
Step-by-step explanation:
you add 1 to 1 and that gives you 2
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

4x-12+12=28+12=40
40/4=10
x=10
$4.20
that is the answer to the question
Looks like 14.4 because you have to add them all together and divide by the total numbers
(20+22+10+5+15)/ 5
