Answer:
Step-by-step explanation:
How do you find the midpoint of A and B?
To calculate it:
Add both "x" coordinates, divide by 2.
Add both "y" coordinates, divide by 2.
The coordinates of the midpoint of the line segment with endpoints A(4, 2) and B(1, -2) are found by averaging the corresponding x- and y-coordinates of the endpoints. This yields a midpoint of (2.5, 0)
The coordinates of the midpoint of the line segment with endpoints A(4, 2) and B(1, -2) can be determined by the midpoint formula. The midpoint formula states that the x-coordinate of the midpoint is the average of the x-coordinates of the two endpoints, and the y-coordinate of the midpoint is the average of the y-coordinates of the two endpoints.
Therefore, the x-coordinate of the midpoint is:
(x1 + x2) / 2 = (4 + 1) / 2 = 2.5
and the y-coordinate of the midpoint is:
(y1 + y2) / 2 = (2 + -2) / 2 = 0
Hence, the coordinates of the midpoint of AB are (2.5, 0).

Answer:
There are 200 girls in that school
Step-by-step explanation:
The correct and complete question is as folly;
In a school 3/5 pupils are boys. One day 1/6 of the boys were absent when 250 boys were present. How many girls are in the school?
SOLUTION
Let the total number of students in the school be x students
Since 3/5 are boys , then the number of girls in the school would be 1-3/5 = 2/5
The number of boys are 3/5 * x = 3x/5
The number of girls are 2/5 * x = 2x/5
Now on a particular day, 1/6 of the boys were absent and 250 boys were present.
What this means is that the fraction of boys present is 1-1/6 = 5/6
Now, 5/6 of the total boys population were present.
Mathematically;
5/6 * 3x/5 = 250
3x/6 = 250
x/2 = 250
x = 2 * 250 = 500
So there are 590 students in the school.
The number of girls in the school is ;
2x/5 = 2/5 * 500 = 200 girls
