Step-by-step explanation:
(2ab-7a-4) - (7ab-4)
= 2ab - 7a - 4 - 7ab +4
(-) × (-) = (+)
(-) × (-) = (+)-(-4)= +4
then 4 will be cancelled
= 2ab - 7ab - 7a
= -5ab -7a

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

What is the question?
Step-by-step explanation:
Answer:
There are 6 more girls than boys
Step-by-step explanation:
boys :girls : total
2 3 2+3 = 5
There are 30 total students
30/5 = 6
Multiply each number by 6
boys :girls : total
2*6 3*6 5*6
12 18 30
There are 18 girls and 12 boys
18-12 = 6
There are 6 more girls than boys
